Test My Heightmap
Author
Hi,
the last few days, I tried to make a heightmap implementation in OpenGL. Finally, I am at a stage to show it the world ;)
But the real reason I post this, is that I want to know, whether the lighting seems to be okay. I have never done lighting in OpenGL before, so I don't know, if it's correct (the vertex normals). And the more I look at my heightmap, the more I think it is wrong :)
So, please test it download win32 (400 kb)
I just see a really cool looking level. Maybe fix collision detection. On the lighting, I think you got it right. You're not flat shading, and I can't find a flaw with the rest of the shading. Keep it up!
Yes, the culling is a bit dodgy. Also the movement was pretty jerky.
As for the lights, the shadows seem to fall on the wrong side with the red light, but the others look ok. Try inverting the normals.
Other than that, it's looking very nice!

Actually to me it looks as if the both the red and the green moving light lights up the wrong side of the faces. Definitely Invert the normal, or change the winding order in OpenGL.

Thanks for all the answers :)
I've inverted the normals as you said (there was also another bug in the normals calculation). Now it looks much better. So, could you take a look at it again?
The 3D camera is only for testing, normally I use this terrain in an isomectric perspective, and there the culling works fine.

The floor texture is doing crazy things for me. It's moving like superfast for no aparent reason. I really dont know how to explain it.

Okay, I fixed that. It was a multi-texturing problem. I forgot to comment some code out :)
Nice, thanks
your program looks good.
i crashed on me though.
dunno if this was a quick hack up to test your heigthmap or whatever.
maybe you dont care :)
i wasnt paying attention to what i was doing at the time, but i think i was moving off the side
