[Note] floating-point/fixed-point operations versus OpenGL

From the Android NDK example "bitmap-plasma": We're going to perform computations for every pixel of the target bitmap. floating-point operations are very slow on ARMv5, and not too bad on ARMv7 with the exception of trigonometric functions. For better performance on all platforms, we're going to use fixed-point arithmetic and all kinds of tricks I… Continue reading [Note] floating-point/fixed-point operations versus OpenGL
