forge-pipeline-skinned-animations

To load and animate skeletal models in an SDL GPU project, use the ForgeSceneSkinnedModel API to load pre-processed assets like .fscene, .fmesh, .fskin, and .fanim, then compute joint matrices per frame on the CPU and upload them to a GPU storage buffer for real-time vertex skinning.

GPU skinning with pre-processed pipeline assets is achieved by computing joint matrices on the CPU each frame and uploading them to a GPU storage buffer, enabling efficient vertex-stage skinning and real-time character animation during rendering with the Forge pipeline.

To update skeletal animations per frame and render them with shadows, call forge_scene_update_skinned_animation to compute and upload joint matrices, then use forge_scene_draw_skinned_model to render the skinned model, including shadow passes, through the Forge pipeline APIs.

Yes, the Forge pipeline supports reusing transform animations for non-skinned models when needed, allowing you to apply similar animation update and world-transform propagation logic without relying on the full vertex skinning storage buffer workflow.

Pipeline-based skeletal animation in SDL requires pre-processed asset formats including .fscene for scene data, .fmesh v3 for meshes, .fskin for skinning data, and .fanim for animation data to properly load and animate models via the ForgeSceneSkinnedModel API.
