Class AnimatedModelCache

Singleton cache managing shared AnimatedModelData instances with reference counting. Ensures each unique GLB file is loaded into GPU memory only once.

EstimateMemoryBytes()

Conservatively estimates the bytes consumed by cached AnimatedModelData entries. Per-cache-entry estimate sums:

  • Mesh vertex buffers across all meshes (32 bytes/vertex for position+normal+uv).
  • Index buffer (4 bytes/index, triangle list).
  • Skeletal animation pose data (animationCount * boneCount * frameCount * 64 bytes per Raylib Transform).
GPU upload overhead and embedded textures are NOT counted here — they live in the asset registry's texture estimator. Intended for diagnostics; O(N) over cached models.
Declaration
public long EstimateMemoryBytes()
Returns
Type Description
long

GetOrLoad(string)

Returns an existing AnimatedModelData for the given path (incrementing ref count), or creates a new one if not yet cached.

Declaration
public AnimatedModelData GetOrLoad(string filePath)
Parameters
Type Name Description
string filePath
Returns
Type Description
AnimatedModelData

Release(AnimatedModelData)

Decrements the reference count for the given data. When ref count reaches 0, the data is disposed and removed from the cache.

Declaration
public void Release(AnimatedModelData data)
Parameters
Type Name Description
AnimatedModelData data
