forge-transform-animations

What problem does it solve?

Add keyframe animations to an SDL3 GPU scene by loading glTF data and applying animated transforms to a node hierarchy.

Core Features & Use Cases

• Load glTF animation data into a scene graph and drive transforms per frame.
• Evaluate animation channels with binary search and interpolation (slerp for rotations, lerp for translations/scales).
• Propagate local transforms through the node hierarchy to produce correct world transforms, and support multiple animation layers (data-driven + procedural) for complex motion.
• Use cases include spinning wheels, walking characters, vehicles following paths, and any keyframe-driven motion within an SDL GPU pipeline.

Quick Start

Load a glTF model and start the animation loop to see keyframe-driven motion.
