Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
A diamond plate texture rendered close-up using physically based rendering principles. Microfacet abrasions cover the material, giving it a rough, realistic look even though the material is a metal. Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map.
Static grass is used in scale models and miniatures to create realistic-looking grass textures. It consists of small coloured fibres charged with static electricity , making them stand on end when sprinkled onto a surface coated with glue that then hardens, holding the fibres in place.
A normal pointing to top right corner of the texture (1,1,0) is mapped to (255,255,128). Hence the top-right corner of an object is usually light yellow. The brightest part of a color map. A normal pointing to right of the texture (1,0,0) is mapped to (255,128,128). Hence the right edge of an object is usually light red.
A normal shader (left) and an NPR shader using cel-shading (right). Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism.
Blender users can create their own nodes using the Open Shading Language (OSL); this allows users to create stunning materials that are entirely procedural, which allows them to be used on any objects without stretching the texture as opposed to image-based textures which need to be made to fit a certain object. (Note that the shader nodes ...
Diagram showing vectors used to define the BRDF. All vectors are unit length. points toward the light source. points toward the viewer (camera). is the surface normal.. The bidirectional reflectance distribution function (BRDF), symbol (,), is a function of four real variables that defines how light from a source is reflected off an opaque surface. It is employed in the optics of real-world ...
