Function Documentation

loadModel()

bool loadModel	(	const std::string &	path,
		LoadedModel &	outModel,
		bool	flipUVs = false
	)

Load a model file via Assimp and decode its embedded textures.

Extracts PBR material properties (metallic, roughness, emissive factors) and tangent vectors for normal mapping. Traverses the full scene-graph and bakes per-node transforms into vertex data.

Parameters

path	Absolute path to the model file (GLB, OBJ, FBX, …).
outModel	Filled on success.
flipUVs	Flip V texture coordinates (V = 1 − V). Set true for models from tools that use V=0 at bottom (Blender, OBJ).

Returns

True on success; false on failure (error logged via SDL_Log).
