OpenGL picking and finding hitpoint of texture
-
18-06-2021 - |
Question
I'm currently into looking into picking using a ray. I can find which model is selected, but how can I retrieve the position on the texture which is picked? I'm talking about a quad in this case.
Edit: Also, if I want to check whether the hitpoint is transparent/translucent, can I best check this with a shader?
Solution
I figure by splitting the quad after getting the specific quad id, then picking again, will give me a point on the quad.
