Its been just short a year since I last done any graphics programming, so I sit down and start writing a simple engine to write some games with. Got the map loader working, so I've just went to put lighting in, not a difficult task. The only problem is that the lighting is not working correctly. My normals are correct, already checked that, but anyways, here is a few shots:
This one is with the light in the same position as the camera. The origin of the world is roughly in the centre of the balls.
And now the light position is roughly at the origin.
And the light just not being correct inside a quake level - red lines are the vertex normals for each face, and the red ball is the light position. Will be the same problem as is causing my balls to be rendered as if they were using directional lighting.
I think that the light is being calculated where the lights direction is relative to the origin, not to each vertex for some reason, but I don't have the foggiest idea why, and no web site or text book is helping me out at all here. Some other information: each one of the those balls is a seperate mesh, the vertices locations are actually where they are draw, the balls dont have a position, just a mesh. After I load my camera matrix into GL, I set the lights position, and then render the mesh of each brush.
Anyone had any similar problems with lighting, and if so how did you solve the problem?
