METHOD, SYSTEM, AND COMPUTER PROGRAM PRODUCT FOR MODIFIED BLENDING BETWEEN CLIP-MAP TILES |
摘要 |
A method, system, and computer program product for modifying blending between at least first and second clip-map tiles. Blending of a texel accessed in a modified blending region of the first clip-map tile is modified such that a blending profile between the first clip-map tile and a second clip-map tile is more smooth. Sharp transitions in blending between the first and second clip-map tiles are reduced or avoided. The magnitude of the modification of blending is a function of the location of the texel within the modified blending region. In one example, a determination is made on whether a texel to be accessed lies within a modified blending region within the first clip-map tile. A modified blending coefficient b is calculated when the texel to be accessed lies within the modified blending region.
