trilinear interpolation A texture mapping technique that produces the most realistic images and requires the most computations. This technique is used in conjunction with MIP mapping, which provides texture maps in different depths.An algorithm is used to map a screen pixel location to a corresponding point on the two nearest texture maps (MIP maps). A weighted average of the attributes (color, alpha, etc.) of the four surrounding texels on each MIP map is computed (bilinear interpolation). Then the weighted average of the two results is applied to the screen pixel. This process is repeated for each pixel forming the object being textured. The term trilinear refers to the performing of interpolations in three dimensions (horizontal, vertical and depth). See texture map, MIP mapping, bilinear interpolation and point sampling.

Unlike other 3D graphics accelerators available today, RealiZm V25 uses the highest-quality texturing at full speed with trilinear interpolation of MIP-mapped images -- with no trade-offs made in features, performance and quality -- guaranteeing accurate, artifact-free displays at all depths. Sophisticated trilinear interpolation creates the rich textures necessary for 3D applications, and is supported by RealiZm 3D's huge texture memory, which provides up to 64MB of texture RAM. |
