I have loaded a .RAW file into a 2x2 array in my class. The way I am rendering it works fine but I am struggling to get the camera to move on top of the terrain. The terrain renders from 0,0,0 (x,y,z) as that is where I put my camera. My camera class allows to the "camera" to move through the scene.

I want to be able to "walk" on top of the terrain with some basic collision detection (if possible). Any tips on where to go for this or any tips?

An easy thing to do that doesn't involve collision detection would just be to figure out the height of the heightmap at a given X,Y location and just set the Z value (assuming Z is up) of the camera (plus some offset probably) there. – Tetrad♦ May 7 '12 at 16:22
@Tetrad +1 That's the first step to collision, once you know the height (Z in your case) and you have XY, there ya go =) But just the height would work really well for a camera. – Patrick Hughes May 7 '12 at 19:07
This is a lot to ask in one go. Collision detection alone is a big topic. – Nicol Bolas May 8 '12 at 2:05
Thanks for commenting. I have tried something like that except I think the problem lies with rendering my heightmap and storing the x and z values (y is up for me). So I have rendered my heightmap from the array and then when each point is being rendered I save that value in another array so I have array of z and x and then test like that but it does not seem to work... – M1kstur May 12 '12 at 17:43
