Hello, You most definitely need to write a GLSL shader when dealing with OpenGL ES 2.0 or later. But it will be a very simple one where you need to sample two textures and calculate mixed color output value from them.
Instead of calculating linear interpolation by hand there is a built-in command "mix" too which gives you linear interpolation between two values. Or "smoothstep" if you prefer to do the so called accelerate-deccelerate interpolation within shader code. -- Harri On Dec 29, 2014 1:30 PM, "MobileVisuals" <[email protected]> wrote: > That sounds promising!
