Detailed Description

handles properties associated with a texture map

vtkTexture is an image algorithm 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.; Some renderers such as old OpenGL require that the texture map dimensions are a power of two in each direction. If a non-power of two texture map is used, it is automatically resampled to a power of two in one or more directions, at the cost of an expensive computation. If the OpenGL implementation is recent enough (OpenGL>=2.0 or extension GL_ARB_texture_non_power_of_two exists) there is no such restriction and no extra computational cost.
