ABSTRACT
Texturing plays a key role in increasing the visual realism of the 3D scene. In general, a texture is organized in an array of texels. When the texels store color information, the texture is called an image texture. The texture dimension is not limited to 2D. For example, a 1D image texture is used for coloring a curve. Nonetheless, the main use of a texture is to store 2D image data, and this chapter focuses on 2D image texturing.
