I am thinking about using opengl picking vs. ray picking.
My program is a pretty simple 2D program so picking will probably be sufficient and i won’t have to get into reverse projecting and intersection detections.
There is one thing i couldn’t find the answer to and i’d like to know before i choose.
When i have a polygon that has a texture on it, and part of the polygon is transparent (due to 0 value in the texture alpha channel), when i click on the transparent part will it get picked or not (obviously i’d like it to not get picked).
Also, in this same case how would ray trace picking help?
Thanks for your help
