Hi,
I have finally gotten around to implementing tangent space calculations into my program, and I now have basic Parallax Mapping working beautifully. But now I don’t know which way to head.
I have read up on Parallax Occlusion Mapping and Steep Parallax Mapping and both seem impressive. Although I find the example for Steep Parallax Mapping, even more so.
Does anyone with experience with these two recommend a specific one, or is there some other method out there that I should head towards?
I am going for decent quality, but I still want it to run in real time. So relief mapping seems out of the equation.
Also, how does Parallax Mapping differ from Offset Parallax Mapping?
On a different topic, I have lighting in my program which seems to work (specifically diffuse). But I have noticed that on large flat surfaces, the light seems to create a cone from the light position outwards in one direction. So where the light is, the lighting is tighter from behind the light, and spreads alot further from the other side of the light. My light is not set to directional, but it seems to eminate from the light in a certain direction, even though it shouldn’t.
Imagine pointing a torch at a wall on an angle. The light spreads outward along the wall, and doesn’t spread so much where it first contacts the wall.
I will post some images later of this problem, as I am not on my computer at the moment (argh, school). The torch reference was the closest thing I could think of.
Any help would be greatly appreciated.
Thanks.
