technique which allows to simulate an higher number of polygons on a given object using a specific texture. For example, with the tread in a tire you can avoid to create grooves using a bump-mapped texture.
A new 3D feature implemented into the newest video cards. This allows for advanced texture filtering to look as if you ran your finger across a texture with bump mapping, that you could feel it.
A technique used to simulate rough or bumpy textures.
A process by which textures are assigned depth information, which allows the display of relief or raised structures.
Bump mapping is a means of applying textures to give the 2D image on screen a more rough (or bumpy) 3D appearance. Lighting effects are used to create light and dark areas to simulate the surface of items like walls, rocks, etc.
This is a technique used in rendering to create the illusion of texture. Two textures are used; the ordinary texture and a bump map. The bump map is usually a greyscale image that will represent the texture's displacement on the image surface. It creates dark areas (depressions) and light areas (elevations).
A shading technique using multiple textures and lighting effects to simulate wrinkled or bumped surfaces. Bump mapping is useful because it gives a 3D surface the appearance of roughness and other surface detail, such as dimples on a golf ball, without increasing the geometric complexity. Some common types of bump mapping are Emboss Bump Mapping, Dot3 Bump Mapping, Environment Mapped Bump Mapping (EMBM) and True, Reflective Bump Mapping.
A 3D rendering lighting technique designed to give a texture a three-dimensional, animated feel.
Bump mapping adds lighting detail to an otherwise flat surface, giving the surface a "bumpy" look and feel. There are several methods for creating bump mapping, one involves using paletted textures and the other involves multi-pass rendering. Voodoo3 3D supports both these methods at full rendering performance and with all filtering modes. In fact, Voodoo3 supports bump mapping at full speeds, in a single pass and single cyle. This full speed approach to bump mapping makes Voodoo3 unique among graphics architectures, offering full speed performance even while bump mapping.
Bump mapping is a computer graphics technique where at each pixel, a perturbation to the surface normal of the object being rendered is looked up in a heightmap and applied before the illumination calculation is done (see, for instance, Phong shading). The result is a richer, more detailed surface representation that more closely resembles the details inherent in the natural world. Normal mapping is the most commonly used bump mapping technique, but there are other alternatives, such as Parallax mapping.
