Hi Dj.
Here is the fragment shader that does the polar coordinates I spoke of:
#extension GL_OES_EGL_image_external: require
uniform samplerExternalOES tex_sampler_0;
precision mediump float;
varying vec2 v_texcoord;
const float PI = 3.14159265358979323846264;
const vec2 texOff = vec2(0.0, 0.0);
const vec2 texSize = vec2(1.0, 1.0);
void main(void) {
vec2 norm = (1.0 - v_texcoord) * 2.0 - 1.0;
float theta = PI + atan(norm.x, norm.y);
float r = length(norm);
vec2 polar = 1.0 - vec2(theta / (2.0 * PI), r);
gl_FragColor = texture2D(tex_sampler_0, (polar + texOff) * texSize);
}
I have tested it myself, and it seems to work great.
