Detailed Description

vtkTexture is an object that handles loading and binding of texture maps. It obtains its data from an input image data dataset type. Thus you can create visualization pipelines to read, process, and construct textures. Note that textures will only work if texture coordinates are also defined, and if the rendering system supports texture.
Instances of vtkTexture are associated with actors via the actor's SetTexture() method. Actors can share texture maps (this is encouraged to save memory resources.)
- Warning:
-
Currently only 2D texture maps are supported, even though the data pipeline supports 1,2, and 3D texture coordinates.
- Warning:
-
Some renderers such as OpenGL require that the texture map dimensions are a power of two in each direction. Other renderers may have similar (ridiculous) restrictions, so be careful out there... (Note: a recent change to vtk allows use of non-power of two texture maps in OpenGL. The texture is automatically resampled to a power of two in one or more directions.)
