Detailed Description

Texture2D class is for processing 2D textures. The class is used to create textures on the fly or to change the existing texture resources.

The ordinary surface mesh of object geometry gives a rough approximation of a form, while most of minutiae is presented as a texture. Texture2D is a standard bitmap image that is applied to a surface mesh. You can think of a texture image, as if it would be printed on "rubber sheet" able to stretch and be fixed to this mesh in corresponding positions. Positioning a texture is performed with the software of math kernel that is used to create a surface mesh. Texture2D can import textures from most common file formats of images, i.e. those formats supported by, for example, Vision::Image. Texture2D has a set of useful functions. Texture2D can be initialized in two ways: using image or bit map, besides, there is a capability to convert a texture to Vision::Image.
