forge-skinning-animations

What problem does it solve?

Real-time skeletal animation for SDL GPU projects by applying glTF skinning data (joints, inverse bind matrices, and per-vertex weights) to deform meshes, enabling believable character animation.

Core Features & Use Cases

• GlTF skinning data support: joints, inverseBindMatrices, and weights enable correct deformation.
• Shader-based skinning: four-joint weighted skinning in the vertex shader for performance.
• Animation evaluation: per-frame evaluation of animation channels and hierarchical transform propagation to update joint matrices.
• Pipeline integration: integrates with SDL GPU rendering and existing asset pipelines for animated characters.

Quick Start

Load a glTF model with skinning data and run the provided skinning shader to render an animated character.
