Linear, high precision HalfFloatType buffers don't have these issues and are the preferred option for HDR-like workflows on desktop devices. Mips are copies of the texture, each one half as wide and half as tall as the previous So the trick here is to use some math to transform 1 unit to 1 pixel and change the perspective to increase or decrease the distortion effect. The noise pattern will evolve and change over time. As you can notice, we have created a plane of 1 on 1px with 1 row and 1 column.
