| // Project the point cloud V_source onto the triangle mesh | |
| // V_target,F_target. | |
| // A ray is casted for every vertex in the direction specified by | |
| // N_source and its opposite. | |
| // | |
| // Input: | |
| // V_source: #Vx3 Vertices of the source mesh | |
| // N_source: #Vx3 Normals of the point cloud | |
| // V_target: #V2x3 Vertices of the target mesh | |
| // F_target: #F2x3 Faces of the target mesh | |
| // | |
| // Output: | |
| // #Vx3 matrix of baricentric coordinate. Each row corresponds to | |
| // a vertex of the projected mesh and it has the following format: | |
| // id b1 b2. id is the id of a face of the source mesh. b1 and b2 are | |
| // the barycentric coordinates wrt the first two edges of the triangle | |
| // To convert to standard global coordinates, see barycentric_to_global.h | |
