Shading of images using texture
摘要:
Colors are obtained and used to shade two-dimensional non-photo realistic images of three-dimensional models. The colors are stored as texels in texture maps. The texels are chosen to shade the images based on their orientation in a scene. The colors may be obtained once, in a pre-rendering process. The colors may then be selected in a run-time process.
