Web14 de ago. de 2016 · Generating a geometry that has one vertex per pixel Let’s do the calculations in the vertex shader instead of the fragment shader. OpenGL ES guarantees high precision floats in vertex shaders but not in fragment shaders, so generating the fractal there should greatly increase the resolution. WebOpenGL ES exposes a precision modifier that allows control of the desired precision for different data types: highp, mediump and lowp. When used on floats, the mapping is typically as follows: highp - generally 32-bits (on some devices 24-bits in fragment shader) mediump - generally 16-bits lowp - generally 11-bits
