glmFromAiTransform()

glm::mat4 AssetLoader::glmFromAiTransform ( const aiMatrix4x4 & transformAi )

staticprivate

Convert an Assimp 4x4 matrix to a glm::mat4.

Parameters

transformAi

The Assimp transform matrix.

Returns

The equivalent glm::mat4.

loadAsset()

const aiScene * AssetLoader::loadAsset ( Assimp::Importer & importer, const std::string & fileName, const bool flipUVs )

staticprivate

Read a file from disk through Assimp and return the parsed scene.

Parameters

importer	Assimp importer instance (owns the scene lifetime).
fileName	Path to the asset file.
flipUVs

Returns

Pointer to the loaded scene, or nullptr on failure.

loadMesh()

bool AssetLoader::loadMesh ( MeshIdInt id, const aiMesh & asimpMeshResult )

staticprivate

Import a single Assimp mesh into the global Asset::meshes_ registry.

Parameters

id	Unique mesh identifier.
asimpMeshResult	The Assimp mesh to import.

Returns

True on success.

loadModel()

bool AssetLoader::loadModel ( const ModelIdInt id, const std::string & modelFileName, const std::vector< std::string > & texFileNames, const bool k_flatten, const bool flipUVs )

static

Load a single model from file and register it in Asset::models_.

Parameters

id	Unique model identifier.
modelFileName	Path to the model file.
texFileNames	Paths to associated texture files.
k_flatten	If true, flatten the scene hierarchy via Assimp pre-transform.
flipUVs

Returns

True on success.
