C# Class open3mod.MaterialMapper

Map assimp materials to OpenGl materials and shaders. Each scene has its own MaterialMapper, which is accessible via the Scene.MaterialMapper property. The class interface is implemented for every type of renderer.

Public Methods

Method	Description
ApplyGhostMaterial ( Mesh mesh, Assimp.Material material, bool shaded ) : void
ApplyMaterial ( Mesh mesh, Assimp.Material mat, bool textured, bool shaded ) : void	Applies a material to the Gl state machine. Depending on the renderer, this either sets GLSL shaders (GL3) or it configures the fixed function pipeline (legacy/classic).
BeginScene ( open3mod.Renderer renderer ) : void
Dispose ( ) : void
EndScene ( open3mod.Renderer renderer ) : void
IsAlphaMaterial ( Assimp.Material material ) : bool	Check if a given assimp material requires alpha-blending for rendering
UploadTextures ( Assimp.Material material ) : bool	Uploads all the textures required for a given material to VRAM (i.e. create the corresponding Gl objects). Textures that have been uploaded before are not attempted again.

return	void

ApplyMaterial() public abstract method

Applies a material to the Gl state machine. Depending on the renderer, this either sets GLSL shaders (GL3) or it configures the fixed function pipeline (legacy/classic).

public abstract ApplyMaterial ( Mesh mesh, Assimp.Material mat, bool textured, bool shaded ) : void
mesh	Assimp.Mesh	Mesh to be drawn. This parameter may be left null /// to use a material with geometry other than assimp meshes (i.e. /// for the material preview tab). In this case, it is assumed that /// the geometry to be used with the materials specifies normals, /// one set of UV coordinates but no vertex colors. /// TODO tangents, bitangents? ///
mat	Assimp.Material	Material to be applied, must be non-null
textured	bool
shaded	bool
return	void
