forge-pipeline-morph-animations

To add morph target animation to an SDL GPU pipeline, load .fmesh and .fanim assets, compute per-vertex deltas on the CPU, and upload them to GPU storage buffers for vertex shader displacement using ForgeSceneMorphModel.

Morph target animations work by blending per-vertex position and normal deltas computed on the CPU according to animation weights, then uploading these blended deltas to the GPU for real-time displaced rendering of deformable meshes.

You need FORGE_SCENE_MODEL_SUPPORT enabled, forge_pipeline.h for loading .fmesh and .fanim files, FLAG_MORPHS enabled, and compiled morph shaders scene_morph.vert.hlsl and scene_morph_shadow.vert.hlsl.

Yes, morph targets can be used for facial expressions in an SDL GPU scene by evaluating animation weights and applying per-vertex deltas via ForgeSceneMorphModel for real-time character animation.

Load a morph model using forge_scene_load_morph_model and advance the animation each frame with forge_scene_update_morph_animation to apply real-time per-vertex delta blending.

Yes, morph target rendering supports shadow passes in SDL GPU by utilizing the compiled scene_morph_shadow.vert.hlsl shader alongside the main scene_morph.vert.hlsl shader for displaced rendering.
