NPR stands for Non-Photorealistic Rendering, which is a technique for creating and rendering images that simulate artistic styles or hand-drawn effects. In NPR, textures are commonly used to add painting effects or textures to the image.
Common NPR textures include:
1. Line art texture: used to generate line and contour effects.
2. Watercolor or oil brush stroke texture: used to simulate the effects of brush strokes, adding artistic flair to the image.
3. Texture maps: used to add textures or special effects such as pencil textures, sketches, or ink renderings.
The RGB channels in NPR are primarily used to define color and transparency information. The RGB channel values of each pixel determine the intensity of its corresponding color and transparency.
