Hi there~
I have a shape rendered on the screen and I would like to find the x, y and z coordinates of the shape that is directly under the mouse coordinate. Example - if im running the mouse over a sine wave in 3D- When i do this currently I get the x and y coordinates of the viewport and not the surface.
Does anyone have any advice on how to do this?
Any comments will be much appreciated.
THank you
