<p>The number of computations performed in rendering graphics is reduced by computing certain terms only at the beginning of each scanline (302). A scanline gradient is calculated once at the beginning of each scanline (302) for each of two texture values with respect of the x-coordinate of the scanline (302). Thereafter, a pixel gradient is calculated for each pixel (304) of the scanline (302) with respect to the y-coordinate of the scanline (302). The scanline gradients and pixel gradients are used to find a maximum Rho constant, which is used to select a texture map for rendering the corresponding pixel (304).</p> |
