C# Class Protogame.AssimpReader

Reads a model file using AssImp and converts it to an IModel, which can be used at runtime for rendering, or serialized for storage as an asset.

Public Methods

Method	Description
AssimpReader ( IModelRenderConfiguration modelRenderConfigurations, IRenderBatcher renderBatcher ) : System
Load ( byte data, string name, string extension, byte[]>.Dictionary rawAdditionalAnimations, string options ) : IModel	Load an FBX file from an array of bytes.
Load ( string filename, string name, string>.Dictionary additionalAnimationFiles, string options ) : IModel	Load an FBX file from a file on disk.

Private Methods

Method	Description
BuildBoneWeightingMap ( Assimp.Scene scene ) : Dictionary>	Builds a bone weighting map. A bone weighting map is a map of each vertex to the bone indexes and weightings that apply to it. This is used to build up the map which is assigned against the vertexes in the model. These bone indices and weightings are then pushed through to the hardware in the BLENDWEIGHTS and BLENDINDICES semantic fields.
BuildStaticTransformMap ( Assimp.Scene scene ) : Matrix>.Dictionary	Builds the static transform map. This is used by vertexes which do not have bones to weight them. When there are no bone weights available, we transform the vertexes based on the scene hierarchy directly on import.
ConvertMaterial ( Assimp m ) : Material
ConvertMaterialColor ( Color4D c ) : Color
ConvertMaterialTexture ( Assimp.TextureSlot t ) : IMaterialTexture
GetStaticTransformMatrixForFirstMesh ( Assimp.Node node ) : Matrix?	Returns the cumulative transformation matrix if the specified node or one of it's descendants specifies the transformation matrix for the first mesh in the scene (the only one that this importer processes).
ImportAnimation ( string name, Assimp assimpAnimation ) : IAnimation	Imports an FBX animation, storing the transformations that apply to each bone at each time.
ImportBoneHierarchy ( Assimp.Node node, Mesh mesh ) : IModelBone	Imports the FBX bone hierarchy of the specified mesh, converting each node in the hierarchy to a model bone. This function recursively traverses the hierarchy, calling itself each time with a different node argument.
ImportIndices ( Assimp.Scene scene ) : int[]	Imports the mesh indices from the scene.
ImportVertexes ( Assimp.Scene scene, Vector4>.Dictionary boneWeightingMap, Matrix>.Dictionary staticTransformMap ) : Protogame.ModelVertex[]	Imports the mesh vertexes from the scene and adds the appropriate bone weighting data to each vertex.
LoadAssimpLibrary ( ) : void	Loads the AssImp library.
MatrixFromAssImpMatrix ( Matrix4x4 matrix ) : Matrix	Creates a Matrix from an AssImp Matrix4x4.
