A pixel is the smallestelement of a display. Texels are the pixels that a texture map is composed of. Source alpha pixel blending A combination of alpha transparency and pixel blending. Source alpha pixel blending uses an alpha channel from the texture instead of the vertex. A lighting characteristic that determines how light should reflect offan object.
Specular highlights are typically white and can move around an object, based on camera position.
Supersampling A method of anti-aliasing that involves rendering the scene at a higher resolution than necessary, then reducing it to the required size. This has the effect of smoothing jagged edges across the entire scene, rather than specific lines and objects. The process of reducing complex shapes into a number of simpler shapes. In the case of 3D graphics, this is typically triangles. Wireframe Also known as a polygon mesh.
