PROFILE
Eran Guendelman
Developed a new kernel for the facebookresearch/momentum repository that unifies mesh vertex projection through a bone-parented camera, targeting enhanced reprojection accuracy in skinned mesh pipelines. Leveraged C++ and Python to implement end-to-end gradient flow across vertex skinning, camera extrinsics, and intrinsics, enabling comprehensive optimization for body pose and camera parameters. Exposed Python bindings and batched constraint APIs to streamline solver integration and experimentation in pymomentum.solver2. Applied multi-threaded processing using dispenso parallel_for to improve performance on large meshes. Completed code review and merge processes, demonstrating depth in 3D modeling, algorithm design, and computer graphics within a production research context.

May 1, 2026May 2026 monthly summary for facebookresearch/momentum focused on feature delivery in the reprojection/face of skinning pipeline. Delivered a new kernel that unifies mesh vertex projection through a bone-parented camera with full support for extrinsics and intrinsics, significantly improving reprojection accuracy for skinned meshes. Implemented end-to-end gradient flow across three paths (vertex skinning chain for body pose derivatives, camera bone chain for camera extrinsics, and intrinsics mapping for focal length and distortion). Exposed Python bindings and batched constraint APIs for solver integration, enabling easier experimentation and production use in pymomentum.solver2. Achieved measurable performance improvements via multi-threading using dispenso parallel_for for mesh-heavy scenarios. PR and code review activity completed (Add CameraVertexProjectionErrorFunction, Differential Revision D104585373; fbshipit PR #1390).
