Detailed Description

Skinned mesh with skeletal animation, loaded from FBX (Mixamo).

Uses Assimp to extract skeleton, skin weights, and animation from FBX. Converts to ozz-animation runtime format for efficient CPU-side playback. Each update() call advances the animation clock, samples the skeleton pose, and rewrites the vertex buffer with linear-blend skinning.

Workflow:

1. load() → parse FBX, build ozz skeleton + animation
2. getLoadedModel() → hand to Renderer for initial GPU upload
3. update(dt) each frame → recompute skinned vertices
4. getSkinnedVertices(meshIdx) → re-upload to GPU vertex buffer

)

const

Current frame's skinned vertices for mesh meshIndex.

Parameters

meshIndex

Index of the mesh to query (default 0).

Returns

Reference to the skinned vertex buffer, updated by update().

load()

bool SkinnedModel::load

(

const std::string &

path

)

Load an FBX file containing skeleton, mesh, and animation data.

Parameters

path	Absolute path to the .fbx file.

Returns

True on success (skeleton + at least one skinned mesh + animation).
