Hi Devs, I was trying to find a crafty way of sampling a texture outside of a shader so that I could implement some better collision detection. What I need to know is how to access the color information at an exact coordinate in a texture (not in U,V coordinates). So for example, I would like to scan to (450,323) in a 500x500 texture to see if the alpha component is greater than 0.5f. Any ideas or hint code would be much appreciated! Thanks. -Mokda

Thanks MJP! That put me on the right track. I'll keep an eye out for performance...and probably be back on these forums if I do run into problems ;)
