... the corresponding unit, and the resulting color is passed as input to the next unit, until the final output goes to the next stage of 3D pipeline, i.e., tests and blending. On OpenGL ES 1.1, it ... pixels, and linearly interpolates the associated values such as colors and texture coordinates to the pixels between the vertices. We can express this using so-called barycentric coord...

... since accessing the coarser mipmap levels reduces the texel fetch bandwidth, improves texture cache coherency, and provides higher-quality filtering. 9.2.4 TEXTURE WRAP MODES OpenGL ES supports ... much higher quality and more efficient line and point antialiasing than, for example, multisampling. However, for best results the lines and primitives should be sorted by depth, and dr...

The default rule is still obeyed within each layer, but the layers are sorted in ascending order. The layer with the smallest index gets drawn fir...
