31
- ## 1. 定位与完整流程 [S01–S06]
32
-
33
- - S01 类型:三维飞行穿环计时挑战(12 环三段航线)。
34
- - S02 核心循环一句话:调整姿态 → 穿环 → 应对风场/失速 → 碰撞复位 → 完成航线。
35
- - S03 流程:起飞 → 低空入门环(环 1–4)→ 风场区环链(环 5–8)→ 高空精密环(环 9–12)→ 终点结算。
36
- - S04 最低完整流程:开始界面、起飞、飞行 HUD、漏环警告、复位、结算、重开必须全部存在且有真实入口。
37
- - S05 失败恢复入口:碰撞回最近环前检查点(环序不回退);超时或复位超限判负后一键重开;Esc 暂停。
38
- - S06 本局耦合边速览:碰撞复位系统→环序进度系统(复位不回退环序);风场系统→飞行轨迹系统(区域风持续偏移航迹)。
39
-
40
- ## 2. 完整核心循环与阶段 [S07–S12]
41
-
42
- 完整循环:主菜单 → C01 起飞 → 低空入门环 → 风场区环链 → 高空精密环 → 终点结算 → 重开/返回菜单;任意飞行阶段可 Esc 暂停。每阶段六要素如下(引用本 spec §3–§7 对应规则):
43

86
-
87
- ## 3. 数值口径与全局规则 [G01–G07]
88
-
89
- - G01 统一刻度:速度按单位/秒、坐标按单位计、角度为度;时间用游戏模拟秒(暂停冻结)。
90
- - G02 飞行与失速(本包冻结值):基础巡航速度 60,速度区间 40–90(Shift 加速至 90、松键回落 60,回落为空气阻力自然衰减);速度 <40 触发失速——垂直下坠 20/秒且操控力矩减半;俯冲或加速使速度回到 ≥50 才脱离失速;失速预警(速度 ≤45 时 HUD 黄色预警与预警音,G07);W/S 俯仰、A/D 横滚,均为连续输入。
91
- - G03 航线与穿环(本包冻结值):航线共 **12 环**——低空入门环 4(环 1–4)、风场区环链 4(环 5–8)、高空精密环 4(环 9–12);环为半径 6 的圆环(高空环收窄为半径 4),飞行器中心穿环平面且距环心 ≤6(高空环 ≤4)才计入;必须按 1→12 顺序穿环,穿到未解锁环不计并出漏环警告;环位由 seed=1039 冻结。
92
- - G04 判定与独立 oracle(本包冻结值):失速 oracle——速度降到 35 必然触发失速事件且下坠率 20;俯冲至 55 必然脱离失速。风场 oracle——无风区正对环 6 直线飞行 10 秒横向位移为 0(偏航 0);风场区同操作 10 秒横向位移 150(±15 容差)。穿环 oracle——按序穿环 1、2 计入推进;直飞环 3 平面(跳过环 2)不计且出漏环警告。任何偏离即 FAIL。
93
- - G05 失败与复位(本包冻结值):撞岛体/环架/水面 → 复位到最近已穿环后方检查点(每环配 1 个),复位次数上限 **10 次**(第 11 次判负);航线总时限 **420 秒**(自起飞离地起算,暂停不计入),超时判负。
94
- - G06 风场与暂停(本包冻结值):风场区(环 5–8 区段)持续侧风 15/秒(固定指向,seed 冻结);区内另设 2 个上升气流柱(半径 10,垂直 +25/秒);高空精密环区无风但环径收窄为半径 4。Esc 暂停冻结计时、风场与失速判定,UI 过渡不推进游戏状态。
95
- - G07 复位朝向与手感(本包冻结值):复位后机头朝向下一目标环的航线方向(姿态角重置为航线切向,速度恢复 60 巡航);横滚信息——相机地平线随横滚同步倾斜,HUD 提供俯仰角/横滚角读数;输入到姿态可见响应 ≤100 毫秒(I07)。
96
-
97
- ## 4. 操作与输入 [I01–I07]
98
-
99
- - I01 键位:W/S=俯仰(拉杆/推杆);A/D=横滚;Shift=加速;R=碰撞后手动确认复位;Esc=暂停;结算界面 Enter=重开。
100
- - I02 输入语义边界:失速期间操控输入仍接受但效果减半;暂停/结算期间输入无效;无鼠标瞄准需求。
101
- - I03 HUD 必须显示:速度、当前环序(下一目标环)、计时(420 秒剩余)、复位计数(0–10)、失速预警(黄)与失速警报(红)、风区提示(进入/离开风场区)、俯仰角/横滚角读数(G07)。
102
- - I04 输入优先级:暂停与结算状态阻断全部玩法输入;面板打开时玩法键不串入;同帧多输入按 §6 各机制声明的顺序结算。
103
- - I05 焦点与点击穿透规则:点击画布捕获输入焦点;面板层阻断点击穿透;窗口失焦自动暂停(G06)。
104
- - I06 UI 必须显示的状态:按 §3 G01 刻度与 §7 结算字段显示本 spec 各规则要求的状态(速度/环序/计时/复位/失速/风区),HUD 对照见 rubric。
105
- - I07 输入延迟目标:按键到姿态可见响应 ≤100 毫秒(桌面 P95,每类输入 ≥30 次采样)。
106
-
107
- ## 5. 航线与内容清单 [L01–L04]
108
-
109
- - L01 生成对象:飞行器 1(原创造型)、穿环 12(套件实例化)、环前检查点浮标 12、上升气流柱标记 2、风线仪/风幡若干(风区边界)、起飞平台 1、HUD。
110
- - L02 航线(冻结布局):单条三段穿环航线;环位、气流柱位置与风场向量由 seed=1039 冻结,不随机扩展;环前检查点位于每环后下方 20 单位处(复位用)。
111
- - L03 目标物/交互物/场景/UI 对象:本 spec §3–§7 引用的界面元素(菜单/HUD/结算面板)与交互物(穿环判定体、碰撞体、检查点复位体、气流柱判定体)逐类存在且运行时可进入;**程序性穿环判定体不得烘进装饰场景模型**——环架模型为外观件,判定体由引擎触发器构建(A 层资产诊断重点)。
112
- - L04 冻结需求 vs 实现默认 vs 生成自由度:本 spec 明确写出的数值与数量为冻结需求;未给数值的表现层(装饰造型、配色、粒子参数、音色)为生成自由度,不得评估为缺失;实现默认值必须明确标注且符合核心机制。音效为冻结需求(F06 ��单逐条交付,缺失按 FAIL 计)。
113
-
114
- ## 6. 机制系统 [M01–M04]
115
-
116
- - M01 三维姿态与失速(主机制)
117
- - input:俯仰/横滚/加速输入(玩家)
118
- - precondition:处于飞行阶段(非暂停/结算/复位中)
119
- - state_change:姿态角连续变化;速度 <40 → 失速(下坠 20/秒、操控减半);速度 ≥50 → 恢复巡航;≤45 → 失速预警(黄)
120
- - output:按 G02 结算飞行状态
121
- - observable:失速进入/脱离/预警事件与速度、姿态采样流
122
- - invalid_case:复位中与暂停中姿态输入无效;失速期间输入减半为规则而非错误
123
- - recovery:俯冲或加速回到 ≥50 脱离失速(M01 自恢复);撞体后走 M04
124
- - M02 有序穿环
125
- - input:穿越环平面(系统判定体)
126
- - precondition:环处于已解锁序号(前序环全部通过)
127
- - state_change:仅当前序号环计入并推进环序;漏环不计
128
- - output:按 G03 结算环序
129
- - observable:ring_passed 事件(环号)与 miss_warning 事件
130
- - invalid_case:越序穿环不计且出漏环警告(无副作用);判定体半径按 G03 冻结值(6/高空 4)
131
- - recovery:回头补穿被漏环后继续按序推进
132
- - M03 风场
133
- - input:进入/离开风场区与气流柱(系统判定体)
134
- - precondition:飞行器处于航线空间
135
- - state_change:风区侧风 15/秒持续偏移航迹(偏航须修正);气流柱内获得垂直速度 +25/秒
136
- - output:按 G06 施加风与气流
137
- - observable:风场进入/离开事件与位置差分流(10 秒横移 150±15 可复现)
138
- - invalid_case:风区外无侧风(E02 对照探针)
139
- - recovery:借气流柱爬升或常规俯冲恢复高度
140
- - M04 碰撞复位
141
- - input:撞击岛体/环架/水面(系统)+手动 R 确认
142
- - precondition:发生碰撞且玩家确认(R);或自动(水面)
143
- - state_change:回到最近已穿环后方检查点;机头朝向下一目标环(G07);速度恢复 60;环序进度保持不回退;复位计数 +1
144
- - output:按 G05 计数与判定
145
- - observable:respawn 事件(含检查点 ID、环序、复位计数、朝向)
146
- - invalid_case:未碰撞时 R 无效;结算/暂停期间复位无效
147
- - recovery:第 11 次碰撞 → V02 判负;复位为唯一恢复入口
148
-
149
- 系统耦合边(玩法必需、可复现):
150
-
151
- - E01 from_system=碰撞复位系统 → to_system=环序进度系统;changed_state=复位后环序不回退(已穿环保持、当前目标环不变),复位朝向指向下一目标环;验证方式=state_before/after 环序对照(复位前后环序差分=0)。
152
- - E02 from_system=风场系统 → to_system=飞行轨迹系统;changed_state=进入风场区后持续侧风改变航迹(无修正 10 秒横移 150±15),气流柱内垂直分量 +25/秒;验证方式=风区内外同操作轨迹差分采样。
153
-
154
- ## 7. 成功、失败与恢复 [V01–V05]
155
-
156
- - V01 成功条件:按序穿完 12 环 → 终点结算(显示用时与复位次数)。
157
- - V02 失败条件:复位超过 10 次或 420 秒超时 → 失败结算(注明当前环序与原因)。
158
- - V03 恢复语义:碰撞回最近环前检查点继续(环序与计时不重置);判负后一键重开全量重置(seed 复现)。
159
- - V04 persistent_state:局内(环序进度与复位计数局内保留;重开全量清空)。
160
- - V04 软锁与不可达处理:不设永久软锁——关键目标均可通过正常飞行达成,或触发 V02 失败路径进入结算;结算界面重开为最终恢复出路。
161
- - V05 persistent_state 生命周期:当前动作级状态即时结算;当前局级状态(环序/复位/计时)局内保留、重开清空;跨局状态无。
162
-
163
- ## 8. 世界设定与创作基线 [W01–W08]
164
-
165
- - W01 世界与时代背景:「浮空群岛」的候鸟节——每年季风转向时,群岛信使驾驶滑翔机沿 12 环天路巡游,向各岛灯塔投递新年的第一封信;天路穿过风谷与云柱,是对飞行员技术的最高礼赞。
166
- - W02 场景所在地:悬浮于云海之上的群岛天路——起飞平台立于首岛崖顶,环 1–4 沿低空岛缘铺设,环 5–8 横穿风谷(侧风常驻、双气流柱),环 9–12 升入高空窄环,终点环悬于终岛灯塔上空。
167
- - W03 玩家身份与当前任务动机:玩家是群岛信使候补飞行员,须在 420 秒内按序穿完全部 12 环、且复位不超过 10 次,完成首次正式投递。
168
- - W04 失败代价与结局表达:超时或复位超限=「信件延误」——灯塔灯暗、信封被风卷走(C03 失败意象);完成航线=灯塔点亮、信封送达(C03 胜利意象)。
169
- - W05 叙事来源:滑翔机=信使邮翼机(双翼轻航风格);穿环=群岛灯塔联盟的悬空环门;气流柱=风谷上升暖流;检查点浮标=灯塔联盟的救援浮标。全部原创,不用商业作品命名。
170
- - W06 视觉风格与色彩材质:明快云���插画风;主色=云白 #F4F7F2、邮翼红 #D9553F、灯塔金 #E8B84B、远岛青 #6A9C8F;材质为帆布翼面、轻木机身、铜色环架与半透明风线。
171
- - W07 环境氛围与声音语言:高空风啸与远处海鸟声为底;音效语言=引擎、风线、穿环提示、失速警报、复位(F06 冻结清单);混音优先级:失速警报 > 漏环警告 > 穿环提示 > 引擎 > 风环境。
172
- - W08 故事表达方式:C01 开场交代候鸟节与投递任务 → 过程中风线与环门脉冲承载航线推进 → C03 结算双意象收束;叙事只做包装不改数值。
173
-
174
- ## 9. 演出、镜头与反馈 [F01–F10]
175
-
176

177
- - F02 关键操作镜头变化:穿环瞬间轻微 FOV +4°(0.3 秒);碰撞/复位 0.3 秒中幅震动;失速期间镜头下沉跟随表达下坠感;设置可关闭(F09)。
178
- - F03 输入与延迟:见 I07(≤100ms P95);顿帧不改变计时口径。
179

231
-
232
- ## 12. 参考图绑定 [A01–A02]
233
-
234
- - A01 绑定原则:参考图只约束对应资产的造型、配色与比例,不约束航线布局(环位/气流柱/风场以本 spec L02 与 seed 为准);R 条件提供 images/ 参考图,N 条件仅有文字描述,评测不得因 N 条件未见参考而追加扣分项。
235
- - A02 绑定表(文件 → 对象):
236

245
- ## 13. 复杂度档案
246
-
247
- ```yaml
248
- difficulty:
249
- tier: M
250
- complexity_profile: {coupling: C2, persistence: P1, recovery: R2, runtime_complexity: B2, hidden_state: H0}
251
- dominant_dimensions: [coupling, runtime_complexity]
252
- rationale: "局内多系统耦合:碰撞复位→环序、风场→轨迹两条可复现 A→B 边(C2);实时三维飞行与风场连续判定(B2);环序进度局内推进(P1);检查点复位且环序不回退、失速自恢复(R2);状态全可见(H0)"
253
- downgrade_boundary: "删去按序穿环与复位保留(任意穿环即计、碰撞重开)后降为 S"
254
- upgrade_boundary: "若环序进度或成绩跨局保留并解锁新航线,升 L-Regular"
255
- stress_axes: []
256
- ```
257
-
258
- ## 生成任务明确性补充(2026-10-12)
259
-
260
- > 本补充只约束游戏生成输入,不引用 rubric。所有生成器必须以本文件规则和下列 JSONL 任务为准;未列出的装饰细节可以自由发挥,但不得省略已列资产或生命周期。
261
-
262
- ### 故事与流程最低合同
263
- - **玩家身份与当前冲突**:以 §1、§8 的角色/世界/冲突为唯一叙事入口;开局必须让玩家知道“我是谁、现在要解决什么问题”。
264
- - **阶段性目标**:必须有可操作的阶段目标、至少一次状态变化/升级,并在 §7 的胜利、失败、重开入口中闭环;不能只生成一个无结果的场景演示。
265
- - **结果承接**:胜利/失败都要有明确结果文案或演出,并回到可重开、暂停或标题入口;视频、音频和 VFX 不得推进未完成的玩法状态。
266
-
267
- ### 生成任务清单(JSONL 冻结口径)
268
- - scene:1 个;必须生成连贯可游玩的空间,不得出现下半部文字、拼贴面板、物体 lineup 或 UI。
269
- - object:6 个(text-to-3D 4,image-to-3D 2);object 任务资产为:sky_glider, ring_gate_kit, thermal_column_marker, checkpoint_beacon, wind_stream_vane, takeoff_skydeck。每项只允许一个物体;组合物必须拆成独立任务。
270
- - motion:1 个;覆盖动作:ring_bank_turn。
271
- - video/audio/mechanic/UI:分别为 3/14/1/1 个任务;若某项为 0,只能是本案例明确的 N/A,不得默默遗漏。
272
-
273
- ### Video / motion / audio 生命周期
274
- - Video 每项必须写清 `trigger`、`start_condition`、`duration_sec`、`skippable`、`skip_behavior`、`end_condition` 和进入的下一个游戏状态;播放期间不得偷偷消耗计时或改变战斗/任务数值。
275
- - Motion 每项必须写清 `source_asset`、`trigger`、`start_condition`、`duration_sec`、`loop`、`end_condition` 和 `cancel_behavior`;动作要与对应输入/机制事件绑定,不可只写“walk animation”。
276
- - Audio 每项必须写清触发事件、时长、`loop`、`stop_condition`、优先级和 ducking;关键命中/提示音必须与事件帧同步,暂停/结算时按 §9 处理。
277
-
278
- ### Mechanic / UI / 游玩手感
279
- - Mechanic JSON 与 §1–§7 配对:每个输入都要有 precondition、state_change、feedback、next_state;必须说明失败/禁用分支。
280
- - UI JSON 与 §9/F10 配对:HUD、菜单、结算、暂停、错误/禁用态要有 state binding;关键状态不能只用颜色表达。
281
- - 手感冻结:相机跟随/构图、FOV、碰撞/遮挡、镜头调整与镜头震动必须在 §9 说明;震动反馈必须写明触发、强度和持续时间,并提供关闭设置且不改变判定。
282
-
283
- ### VFX 时机合同
284
- 每个特效必须写清 `trigger event`、预备/前摇、active window、持续时间、结束条件、被打断/取消条件,以及和相机震动、音效、UI 的同步关系;命中特效、失败特效、胜利特效不能只写“有粒子”。

7
- ## 1. 建议首轮组合
8
-
9
- | 类别 | 首轮建议 | 放在哪组 | 选择理由 / 限制 |
10
- |---|---|---|---|
11
- | 3D Object | Meshy + Tripo + 腾讯云 Hunyuan3D Pro 商用 API | B1 商用生成 API;逐版本核对开放权重状态 | 三家即可;人物/刚体、T2/I2 分组,保持同输入和低模预算 |
12
- | 3D Scene | 新增 World Labs Marble World API;保留 WorldPlay/HY-World 2.1 Scene → WorldMirror → 导出,以及 LLM 布局/组合 | Marble 为 B2 商用 direct 候选;另两路为组合方法对照 | Marble 提供世界生成和 mesh 导出;不拿仅视频输出替代 3D 交付 |
13
- | 自然音 / SFX(看情况吧) | ElevenLabs Sound Effects v2 + Stable Audio 3.0 Large 商用 API | B4 Environment / Foley 子组 | 一个面向音效、一个通用音频基线;先用声音事件和环境音 pilot 验证,不跑成音乐任务 |
14
- | 中文人物语音 | MiniMax Speech(优先验证 `speech-2.8-hd`)+ ElevenLabs TTS 的固定中文支持版本 | B4 Speech 子组 | 当前 38 条都是中文;固定说话人、情绪映射和完整台词 |
15
- | CG | Seedance + MiniMax Hailuo(优先验证 `MiniMax-Hailuo-2.3`) | B3;T2V 与 I2V 分开 | 先跑两家即可,不急着加入第三家;按 API 的时长/分辨率能力冻结共同条件 |
16
- | Motion | MoMask + Puppeteer 对比 LLM 直出;可再加 Meshy Text-to-Motion | 前两路是开放模型链 / 系统对照;Meshy 是 B5 商用 API 候选 | 先满足用户要的两路比较;若 B5 必须有闭源专用生成 API,再加第三路 |
17
- | T-pose | 同一份冻结准备输入 | 不新增主表 | 两个动作方法共享角色输入,不把图像准备差异算成动作模型收益 |
18
-
19
- 商用 API 不自动等于闭源模型。特别是 Hunyuan3D 必须登记云端实际版本,不能把本地
20
- 开放权重版本包装成闭源行;MiniMax 的视频实验也要写清 Hailuo 的具体 ID,不能只写品牌。
21
- MoMask、Puppeteer、WorldPlay、WorldMirror 的源码/模型发布可在官方仓库核对 [R1–R4]。
22
- 上述 API 的能力入口见文末官方来源;账户权限和实际可用版本仍需 pilot 确认。
23
-
24
- **规模建议**:B1 三家、CG 两家、音频按两种任务各两家;场景优先补 Marble,而不是
25
- 为了凑三列加入不能导出场景的模型。B2 暂时只有一个确认能力范围的商用 direct 候选,
26
- 如需至少两家闭源 direct API,仍须找到并实测第二家,不能用组合方法假充。
27

28
- ## 2. 为什么按这些方法分组
29
-
30
- 原方案 §1/§4 要求闭源专用生成 API、开放模型与多模型组合分开,首轮主表不混排。
31
- 因此保留用户提出的系统比较,但不悄悄改掉主表含义:
32
-
33
- - B1/B3/B4:按相同任务和输入条件比较商用服务,记录模型的权重开放状态。
34
- - B2:Marble direct 与 WorldPlay + WorldMirror / LLM composition 分 panel 报告。
35
- - B5:MoMask 生成人形动作,Puppeteer 在本项目链路中主要承担绑骨/蒙皮准备;
36
- LLM 直出是另一条系统方法。不能把它们标为两个闭源 motion API。
37
- - 如果研究问题改成“各种资产生成方法谁更适合游戏”,可以增加系统对照表,
38
- 但需要显式修改协议,而不是沿用 `Closed-source method` 表头。
39
-
40
- 为了隔离动作生成能力,建议先冻结一套人形骨架和白模,两路动作采用同一个映射、
41
- retargeter、20 fps 和接触检查;角色网格、绑骨差异另在第三阶段端到端比较。
42
- LLM 直出必须交付轨迹/骨骼动画文件,只有 Blender 脚本、文字或预览视频不算交付成功。
43
-
44
- ## 3. 与当前优先清单对齐的阻塞项
45
-
46
- ### 3D Object:低模与上下文能力
47
-
48
- 现有 200 条保留低模 prompt,且 `decimation_target` 最高 8000。
49
- 建议统一保存原始 API mesh 和固定后处理后的导入 mesh,分别报告;不要只给一家减面,
50
- 也不要把减面后生成的新几何缺陷完全归给原始模型。
51
-
52
- Hunyuan3D Pro 的普通模式中 `Prompt` 与图像输入互斥,不能假设 I2 能同时传游戏梗概。
53
- 这类调用按原方案记为 `reference-only` 辅助组;T2 可以拼接冻结的短版梗概。
54
- 其 3.0/3.1 的 LowPoly 支持不同,先确定使用的版本和后处理政策 [R5]。
55
- 其他 I2 API 也逐一核对文本上下文能力,不能只在 judge 阶段补梗概。
56
-
57
- 不要用 `latest` 当作冻结版本。Meshy 文档还提示其 `lowpoly` 模型类型将在
58
- 2026-10-30 退役;现有清单的 `poly_policy: low_poly_priority` 只是实验政策,
59
- 不等于必须调用这个即将退役的 API 类型 [R6]。
60
-
61
- ### 3D Scene:交付要有真实场景
62
-
63
- 69 条现有场景任���要求 `output_format: glb`。WorldPlay 的视频需经 WorldMirror 重建
64
- 及场景导出后,才与场景任务对齐;只生成视频不能记 Delivery 成功。
65
-
66
- Marble 的世界接口返回 splats 和 collider mesh,并另提供高质量带纹理 GLB 导出。
67
- 建议正式 B2/第三阶段使用后者,保存碰撞网格和世界尺度信息;不要拿无外观的 collider
68
- mesh 冒充完整美术场景,也不要把 splat 文件简单改后缀作为 GLB [R7]。
69
- 生成和导出都计入耗时/成本;若导出不可用,保留该任务的未交付状态,不替换成全景图。
70
-
71
- LLM composition 固定资产池、资产提供者、坐标系统、规划调用数和修补预算;
72
- 若它额外调用对象生成器,费用和调用全部计入系统方法,不能只记 LLM 的 token 成本。
73
-
74
- ### Audio:需要按声音任务选方法,不是一种模型跑全部
75
-
76
- 当前非语音 706 条:623 条 `one_shot`、83 条 `ambient_loop`;语音 38 条,全部中文。
77
- 这是分类字段统计;实际循环要求仍以每条任务的 `loop` / 生命周期字段为准。
78
- 非语音时长为 0.15–45 秒,其中 93 条短于 0.5 秒、281 条短于 1 秒、19 条长于 30 秒。
79
-
80
- ElevenLabs SFX API reference 写 0.5–30 秒,能力总览却写 0.1–30 秒,存在官方文档差异;
81
- 开跑前应实测短音边界并保存实际请求/响应,不自行认定所有短音都支持 [R8, R9]。
82
- Stable Audio 的 API 时长范围也应从具体 endpoint 核对。这里建议验证 3.0 Large 商用服务,
83
- 而不是把已开放权重的 3.0 Medium / Small / Small SFX 当作闭源方法 [R10]。
84
- 若账户仍使用 2.5 API,则固定并单列 2.5 版本,不混写成 3.0 的结果 [R16]。
85
- 共同能力子集用于配对排名;其余任务仍留在第三阶段完整清单中,标注能力缺口。
86
-
87
- 解码、重采样到要求的 48 kHz / 24 kHz 可采用同一确定性工具并保存原件。
88
- 短音裁切、长音拼接/循环、生成式延长不是无代价格式转换:如要使用,须预先冻结规则,
89
- 单列 pipeline 结果及成本,不能悄悄改任务时长来让 API 通过。
90
-
91
- 语音不得把“游戏梗概 + 角色介绍”拼进需要念出的台词。检查 API 是否有独立的
92
- instruction/style 通道;没有时仅可使用冻结的 voice/emotion 参数映射,单列标准 TTS
93
- 条件,不宣称模型直接读取了梗概。MiniMax 的 TTS 参数和 ElevenLabs 版本入口见 [R11, R12]。
94
-
95
- ### CG:现有任务与 reference-image 协议不一致
96
-
97
- 194 条中 190 条 `text_to_video`、4 条 `image_to_video`,但当前全集和优先清单都没有
98
- 参考图路径字段。不能用这批数据直接声称完成“194 条 reference-image-to-video”评测。
99
-
100
- 建议明确选择:保留 T2V 子表、Q1 预声明 N/A;同时为 I2V 冻结真实的共同参考帧,
101
- 补齐路径和来源后再运行 Q1。若要全部改成 I2V,应生成并冻结共享参考图,然后形成新的
102
- 任务版本;不能各视频方法自行画图作为自己的参考。
103
-
104
- 现有时长 4–12 秒、输出 1280×720/24 fps;Hailuo 2.3 文生接口的原生规格是
105
- 768P 的 6/10 秒或 1080P 的 6 秒,不能把原 JSON 原样发出去 [R13]。
106
- 先冻结共同能力 pilot 子集;非原生任务保留并标注,不隐式拉伸视频来满足事件时长。
107
- Seedance 使用已接入的实际 model ID,先验证能力矩阵,不将品牌名当成版本。
108
-
109
- ### Motion:保留非人形与短动作
110
-
111
- 新增 78 条中,76 条人形、G040 一条 vehicle、G030 一条 mechanical。
112
- 两个非人形任务必须保留用于第三阶段,不能因为 MoMask 主要面向人形就删去。
113
- 按 rig group 单列,不支持时明确记录;需要 procedural 交付时另列方法,不冒充 MoMask 结果。
114
-
115
- Meshy Text-to-Motion 的官方接口提供自然语言动作和 FBX/BVH,当前时长要求为
116
- 2–10 秒且按 0.5 秒步长 [R14]。它适合补商用动作 API 对照,但不是现有所有短动作的
117
- 无缝替换。LLM 直出也固定同一骨架、帧数和时长,不只比较好看的视频。
118
-
119
- ## 4. 最小执行顺序
120
-
121
- 1. 先为 13 个 L 级游戏准备第三阶段的全部既有资产任务;完整性与模型共同能力子集是两件事。
122
- 2. 选 G003/G025/G040 等 3–5 个游戏做 pilot,覆盖中文语音、RTS 压力、机械/载具边界。
123
- 每类先挑少量代表任务;这不缩减 L 级正式导入清单。
124
- 3. 冻结游戏梗概、任务/参考输入、适用指标、API 版本、调用次数、超时重试和后处理。
125
- 4. 报 Delivery、C、Q1/Q2/Q3、Coverage 和成本,按游戏宏平均;不挑 best-of,也不将
126
- 未测能力缺口伪装成 API 生成失败。正式分母政策在开跑前固定。
127
- 5. 第三阶段各 repair 方法共享同一冻结资产包。提前固定每类资产的交付来源,不能按
128
- 单条 judge 最高分挑选,也不能悄悄用 LLM 补产物来遮盖某个生成方法的失败。
129
- 若比较资产来源,另设因子并保持 repair 方法与预算一致。

8
- Contract: `agent_skills/develop_harness/api_model_require.md` R9.

- This module owns R9.6 (submit → poll → download behind a blocking call),

13
- It knows nothing about 3D, audio or video — only HTTP, money and failure modes.

- Why this exists instead of `trimesh.load(...)`: the API wrappers must report the
7
- triangle count of what they just paid for (`api_model_require.md` R9.8), and

- that number has to be available on a CPU-only box with nothing but the stdlib

11
- `glb_summary` and `glb_triangle_count` read the JSON chunk only. `read_glb_mesh`
12
- decodes vertex data as well, because a generated part has to be *composed* with
13
- primitives rather than merely counted, and that needs its triangles in the same

3
-
4
- MeshyModel — wrapper around Meshy's cloud 3D-generation API (image-to-3D and
5
- text-to-3D), producing GLB / FBX / OBJ / USDZ / STL.
6
-
7
- Reference: https://docs.meshy.ai/ (base https://api.meshy.ai)
8
-
9
- Second backend for the `gen_3d_object` slot. Its `infer` / `infer_and_save`
10
- signatures are identical to `TripoModel`'s and positionally identical to
11
- `Trellis2Model`'s, so `Gen3DObjectOperator` dispatches on class name alone
12
- (model_require.md R6).
13
-
14
- CONTRACT DEVIATIONS (model_require.md targets local-weight models; the rules that
15
- replace it live in agent_skills/develop_harness/api_model_require.md):
16
- C1 R2.1/R2.2 → R9.1 `model_path` carries a *model version id* ("meshy-6").
17
- C2 R2.3 → R9.2 `device` accepted for interface parity and ignored.
18
- C3 R3.6/R5.5 → R9.3 no @torch.no_grad(); torch is not involved.
19
- C4 R4.1-R4.3 → R9.4 `unload()` is a no-op that closes the HTTP session.
20
- C5 R3.3/R3.4 → R9.5 `seed` is forwarded for text-to-3D only, where the API
21
- accepts it; image-to-3D has no seed. Reproducibility is
22
- NOT guaranteed server-side and is never faked locally.
23
- C6 R3.1 → R9.6 task-based API (submit → poll → download); `infer()`
24
- blocks until completion or `timeout` (default 300 s).
25
- Text-to-3D runs two tasks (preview → refine) when a
26
- texture is requested; both ids are logged.
27
- C7 R1.2 uses the documented `infer_and_save(..., output_path)`
28
- exception; the bytes-returning `infer()` exists alongside.
29
- C8 (new) → R9.8 `cache_dir` prevents re-billing an identical request.
30
- C9 (new) → R9.9 `max_retries` + exponential backoff; retryable and
31
- terminal failures are split.
32
-
33
- Environment:
34
- MESHY_API_KEY required at the first infer() call, not at construction.
35
- Get one at https://www.meshy.ai/api (a `msy_dummy_...`
36
- test-mode key returns canned assets without spending credits).
37
- MESHY_API_BASE optional override of the API root.
38
- `pip install requests` is needed for the API backends only.
39
-
40
- Usage:
41
- from models.gen_3d_object.meshy_model import MeshyModel
42
- model = MeshyModel(model_path="meshy-6", output_format="fbx")

- CONTRACT DEVIATIONS (model_require.md targets local-weight models; the rules that
10
- replace it live in agent_skills/develop_harness/api_model_require.md):
11
- C1 R2.1/R2.2 → R9.1 `model_path` carries a *model version id*
12
- ("v3.1-20260211"), not a weight location.
13
- C2 R2.3 → R9.2 `device` accepted for interface parity and ignored.
14
- C3 R3.6/R5.5 → R9.3 no @torch.no_grad(); torch is not involved.
15
- C4 R4.1-R4.3 → R9.4 `unload()` is a no-op that closes the HTTP session.
16
- C5 R3.3/R3.4 → R9.5 `seed` is forwarded as model_seed/texture_seed when the
17
- provider accepts it; server-side reproducibility is NOT
18
- guaranteed and is never faked locally.
19
- C6 R3.1 → R9.6 task-based API (submit → poll → download); `infer()`
20
- blocks until completion or `timeout` (default 300 s).
21
- A timeout error carries the `task_id`.
22
- C7 R1.2 uses the documented `infer_and_save(..., output_path)`
23
- exception; the bytes-returning `infer()` exists alongside.
24
- C8 (new) → R9.8 `cache_dir` prevents re-billing an identical request.
25
- C9 (new) → R9.9 `max_retries` + exponential backoff; retryable (5xx/429/
26
- transport) and terminal (400/401/402) failures are split.

- Environment:
29
- TRIPO_API_KEY required at the first infer() call, not at construction.

-
45
- * naming an ``asset_id`` in the task hands the finished mesh to the
46
- three.js adapter — staged, oriented, manifest rewritten;
47
- * ``run_art_plan(game_id, image_model)`` generates a whole game's
48
- recorded art plan (``funcs/art_plan.py``) that way in one call.
49
-
50
- ``funcs/asset_pack.py`` covers the other case: three CC0 models,
51
- downloaded and imported in seconds, for when generating is overkill.
52
-
53
- A third route skips inference entirely. Passing ``spec`` instead of an
54
- image builds the mesh from a declarative part list
55
- (``funcs/code_asset.py``), which suits anything exactly describable — a
56
- crate, a sign, a wheel, a rifle. It needs no model and no GPU, states its
57
- own facing and size instead of leaving them to be guessed, and keeps its
58
- parts as named glTF nodes so gameplay can still move them::

73
- The two can be mixed, which is usually the best available answer for a
74
- detailed hard-surface asset. A ``mesh`` part reads a GLB off disk — one
75
- component generated by a cloud model — and is placed, measured and gated
76
- exactly like a primitive. What each side contributes is not
77
- interchangeable: the generator supplies shapes no formula states (a
78
- moulded grip's finger swells), and the spec supplies the dimensions and
79
- placement a prompt cannot specify (a rail's 30 mm slot pitch). Spending
80
- generation on something a lathe states exactly buys an approximation at a
81
- hundred times the triangles, and the approximation is the part that can no
82
- longer be adjusted by editing a number — so the ``provenance`` gate
83

2
-
3
- 你正在执行同一个游戏测例的第二阶段资产生成。**开始前必须先阅读 `{SETTING_OVERVIEW}`,并严格遵循其中的 asset refinement、asset QA 和 validation 流程。**
4
-
5
- ## 测例输入
6
-
7
- - 游戏测例:`{GAME_ID}`
8
- - 测例目录:`{CASE_ROOT}`
9
- - GameFactory-3A 根目录:`{FRAMEWORK_ROOT}`
10
- - 总入口文档:`{SETTING_OVERVIEW}`
11
- - 目标引擎:`{ENGINE}`
12
- - 完整游戏需求:`{GENERAL_REQUIREMENT}`
13
- - 当前 run 根目录:`{RUN_ROOT}`
14
- - runner 控制面(冻结索引、prompt/packet/log):`{GENERATION_CONTROL_ROOT}`
15
- - 第一阶段白模 run:`{WHITEBOX_RUN_ROOT}`
16
- - 第一阶段白模 workspace:`{WHITEBOX_WORKSPACE}`
17
- - 第一阶段资产接口:`{ASSET_SLOTS}`
18
- - 第一阶段计划/TODO:`{GENERATION_PLAN}`
19
- - 外部冻结的资产任务索引:`{ASSET_TASK_INDEX}`
20
- - 资产输出根目录:`{ASSET_OUTPUT_ROOT}`
21
- - 当前阶段 pipeline task 目录:`{STAGE_WORKSPACE}`
22
- - 资产 QA 证据根:`{RUN_ROOT}/eval/<task_kind>/<task_id>/`
23
-
24
- 请读取游戏完整梗概和玩法,再读取 `{ASSET_TASK_INDEX}` 中列出的**每一条**资产任务、对应的 requirement、JSONL 和参考图片。**每一个资产生成任务都必须使用完整游戏梗概作为上下文**,不能只把孤立的资产 prompt 交给生成流程。
25
-
26
- ## 本阶段任务
27
-
28
- 1. 根据第一阶段的任务拆解、TODO 和 `asset_slots.json` 确认资产用途、生命周期、比例、朝向、挂点和风格;
29
- 2. 按 `setting_overview.md` 路由到对应的 T-pose、3D object、3D scene、Motion、Audio、CG video 或其他资产 Skill;
30
- 3. 逐项生成冻结任务索引中的所有资产,并执行对应的结构/视觉 QA;
31
- 4. 保持第一阶段定义的 asset ID 和游戏/UI/mechanic contract 不变;
32
- 5. 记录资产来源、配置、参考图、QA 和后续导入要求;
33
- 6. 生成完整的资产 manifest,供第三阶段导入使用。
34
-
35
- ## 限制
36
-
37
- - 不修改第一阶段核心游戏机制和需求;
38
- - 不擅自删除、合并或跳过资产任务;
39
- - 资产失败必须记录为失败,不能伪造成功;
40
- - 不将资产生成 QA 当成游戏已经完成;
41
- - 本阶段默认不执行 Agent repair。
42
-
43
- ## 输出位置和 Layer 规则
44
-
45
- 资产必须按框架标准布局写入:
46
-
47
- - `{ASSET_OUTPUT_ROOT}/tpose/<task_id>/`;
48
- - `{ASSET_OUTPUT_ROOT}/3d_object/<task_id>/`;
49
- - `{ASSET_OUTPUT_ROOT}/3d_scene/<task_id>/`;
50
- - `{ASSET_OUTPUT_ROOT}/motion/<task_id>/`;
51
- - `{ASSET_OUTPUT_ROOT}/audio/<task_id>/`;
52
- - `{ASSET_OUTPUT_ROOT}/cg_video/<task_id>/`。
53
-
54
- 每个任务目录至少应有资产文件、`meta.json`、预览(若适用)和 QA 证据。资产 manifest 和阶段产物说明写入 `{ASSET_MANIFEST}`(位于标准 `pipeline/<task_id>/` task 目录);冻结索引只读自 `{ASSET_TASK_INDEX}`,runner 控制文件写入 `{GENERATION_CONTROL_ROOT}`。每个资产任务的 QA 证据写入 `{RUN_ROOT}/eval/<task_kind>/<task_id>/`。至少生成:
55
-
56
- - `asset_manifest.json`;
57
- - `asset_generation_report.json`;
58
- - `asset_task_index.json`(由外部入口生成,不得删改任务);
59
- - 失败任务及其失败原因。
60
-
61
- 不要写入 case 输入目录、不要覆盖白模 run,也不要创建 `pipeline/assets/` stage 目录;真实资产必须按 `assets/<task_kind>/<task_id>/` 放置,不能把所有文件平铺在 pipeline task 目录。
62
-
63
- ## 已确认的优先 3D Object 双服务对比
64
-
65
- 当用户明确选择优先 200 条对象任务的 Meshy / Tripo API 对比时,使用
66
- `scripts/asset/generate_3d_comparison.py` 与 `config/asset_3d_comparison.json`,
67
- 具体命令和费用见 `scripts/asset/README_3d_comparison.md`。这是跨游戏的对象生成实验;
68
- 各游戏只包含 3D Object 子集,不能将其标为六类资产齐全的完整 Stage 2。
69
-
70
- - 输入以 `test_data/priority_gen/3d_object_priority_lowpoly_collect.jsonl` 的全部 200 条为准,
71
- 保留原 task ID、prompt、seed、参考图及最高 8000 三角面的既定政策。
72
- - 完整游戏需求保留在冻结输入包;两家文生调用使用完全相同的短梗概和原资产 prompt,
73
- 合计不超过 800 字符。API 未接收完整正文这一事实必须记录,不能宣称正文已送入模型。
74
- - 两家图生均使用同一冻结参考图,列入 `reference_only` 辅助组;不要为了补文字上下文
75
- 悄悄改图、另画参考图、改变原任务的输入模式或仅给一家添加贴图提示词。
76
- - 每家分别运行全部 200 条。按人物/刚体、文生/图生及上下文条件分组;Hunyuan3D Pro
77
- 仅保留后续接入口,本轮不启用、不消耗第三家额度。
78
- - 固定具体模型版本,不使用 `latest`;Meshy 本轮使用 standard + remesh,
79
- 不依赖将于 2026-10-30 退役的 `model_type=lowpoly`。
80
- - 原始 API mesh 写为 `model.glb`,统一后处理的导入 mesh 写为 `import/model.glb`。
81
- 两家使用同一固定工具、参数与贴���上限;分别记录原始和后处理 QA、耗时及缺陷。
82
- 减面未达到预算应如实记录失败,不增加生成次数、不换模型补齐或挑选 best-of。
83
- - 付费调用前需要用户确认预算并在环境中配置密钥。提交后立刻落盘任务 ID;
84
- 已知远端任务只续查结果,提交结果不确定时停下核对,不自动重发付费任务。
85
- - 本轮按游戏级共享资产目录落盘,在任务目录下加厂商一级:
86
- `test_data/outputs/<game_id>/assets/3d_object/<task_id>/<provider>/`,
87
- `<provider>` 为 `meshy` / `tripo`,不使用 `asset_comparison` 输出目录。
88
- 原始 `model.glb`、`import/model.glb`、`meta.json`、服务端预览均放在厂商目录内;
89
- QA 写入 `test_data/outputs/<game_id>/eval/3d_object/<task_id>/<provider>/`。
90
- manifest/阶段报告按游戏、批次、厂商放在
91
- `test_data/outputs/<game_id>/pipeline/<game_id>_pipeline/<batch_id>/<provider>/`,
92
- 冻结输入、计费回执与跨游戏预览保存在 `test_data/outputs/_asset_batches/<batch_id>/`。
93
- 不覆盖不同批次已有的厂商资产,也不覆盖白模工程。
94
- 结构检查通过不等于视觉 QA 通过;C、Q1/Q2/Q3 的正式评分缺少证据时保持 UNKNOWN。
95
- 第三阶段的资产来源需要另行固定,不能按逐条最高评分混选两家产物。
