Hi,
How can I get the difference in z between the camera position and the terrain beneath the camera at its current position?
I want my camera position to always be at 2 units above the terrain.
Thanks in advance..
It depends...you can use the methods for collision detection or calcMinDistance and adjust the height according to the result.
Edit: Depending on the complexity of the terrain, you might want to calculate an OcTree and enable use for collision detection (and disable use for rendering) on it.
