StereoWorld

Official model weights for StereoWorld: Camera-Guided Stereo Video Generation.

Models

This repository contains two models:

Directory	Model	Description
StereoWorldModel/	Fixed-Baseline Stereo	Generates side-by-side stereo video with a configurable but fixed stereo baseline. Use --use_raymap during inference.
StereoWorldFlexModel/	Flexible Stereo	Independent left/right camera control with multiple right-camera modes (converging, horizontal offset, depth offset, height offset).

Fixed-Baseline Stereo (StereoWorldModel/)

A binocular teacher model that produces left-right stereo pairs with a fixed baseline between cameras. Best for standard stereo video generation where consistent disparity is desired.

Flexible Stereo (StereoWorldFlexModel/)

A more general multi-view world model that allows independent camera trajectories for left and right views. Supports four right-camera modes for creative stereo effects.
