WebinterpolateAtSample returns the value of the input varying interpolant sampled at the location of sample number sample. If multisample buffers are not available, the input varying will be evaluated at the center of the pixel. If sample sample does not exist, the position used to interpolate the input varying is undefined. Web"but both do 16 texture reads where only 4 are necessary:" That post is lying to you. Bicubic interpolation is not doing 4 bilinear samplings; that's just linear filtering on a larger scale. Bicubic interpolation requires doing cubic interpolation of the values, not linear interpolation. And you can't do cubic interpolation by doing a bunch of linear interpolations. college park section 8WebVamos jogar Dynamic Rings - GLSL Wallpaper e aproveitar o tempo divertido.
