Mouse position in 3d space
Feb 26th, 2009, 2:20am  
Hey all,
I'm working on a relatively simple game and have created a grid for positioning.  To get a perspective on it, I used the following on the camera position:
rotateX(-PI/7);
translate(-50,190,30);

Now, I've got this grid that looks like this:

Each quadrant of the grid checks if the mouse is over it, but since the mouse position wasn't remapped, it's off by a bit.  
The question: how could I translate the mouse position so it would be in the same plane as the field?  
Thanks in advance!

If you're using OpenGL, you might find some use in:
