I am working originally in projection space with some 3d objects drawn. I am then drawing some objects in orthogonal space so that I can move them per pixel correctly with the mouse position. But I also want to be able to apply 3d rotations to this object.
How can I do a 3D rotation on an object drawn in Orthgonal space?
Keep in mind that when I rotate it, I want perspective and everything to still take place.
Or is there a different way to move it with the mouse so that it still uses correct pixel placement in the window? eg: 100,100 is 100 pixels from the top and 100 pixels from the left.
Thanks.
