Affine texture mapping linearly interpolates texture coordinates across a surface, and so is the fastest form of texture mapping. Some software and hardware (such as the original PlayStation ) project vertices in 3D space onto the screen during rendering and linearly interpolate the texture coordinates in screen space between them.
Projective texture mapping is a method of texture mapping that allows a textured image to be projected onto a scene as if by a slide projector. Projective texture mapping is useful in a variety of lighting techniques and it is the starting point for shadow mapping .
During the texture mapping process for any arbitrary 3D surface, a texture lookup takes place to find out where on the texture each pixel center falls. For texture-mapped polygonal surfaces composed of triangles typical of most surfaces in 3D games and movies, every pixel (or subordinate pixel sample) of that surface will be associated with some triangle(s) and a set of barycentric coordinates ...
Tessellation can also be used for implementing subdivision surfaces, level of detail scaling and fine displacement mapping. [5] OpenGL 4.0 uses a similar pipeline, where tessellation into triangles is controlled by the Tessellation Control Shader and a set of four tessellation parameters.
Graphics Environment for Multimedia (GEM) is a set of externals that provide OpenGL graphics functionality to Pure Data, a graphical programming language for real-time audio processing. It is free under the GNU General Public License (GPL).
The OpenGL Architecture Review Board (ARB) was formed in 1992, in part to establish standards for the GPU industry. The ARB and Nvidia established a number of OpenGL extensions to standardize GPU programming: [1] EXT_texture_env_combine - provided a programmable method of combining textures. NV_register_combiners - GeForce 256
Glide is a 3D graphics API developed by 3dfx Interactive for their Voodoo Graphics 3D accelerator cards. It started as a proprietary API, and was later open sourced by 3dfx. [2] [3] It was dedicated to rendering performance, supporting geometry and texture mapping primarily, in data formats identical to those used internally in their cards.
