Get world coordinates from screen coordinates
Hey there, I am working on a program that requires knowledge of depth information of a particular point on the screen. Currently, I want to get this point through a mouse click on the screen. Becau...
So by pointing device could I still use a mouse? I will have to read up on ray casting in that case.
The point of my application is to simulate retinal blurring when rendering. I need to grab the depth of the point that a person is looking at (simulated by a mouse click) and apply an appropriate blur to the scene. So I guess what I am really looking for is the depth of a point in the scene. Would ray casting be the way to approach this?
