Displacing Vertices in the Vertex shader
My code creates a grid of lots of vertices and then displaces them by a random noise value in height in the vertex shader. Moving around using
glTranslated(-camera.x, -camera.y, -camera.z);
works fine, but that would mean you could go until the…

Lining up terrain chunks (Diamond-square algorithm)
I'm programming a terrain engine that uses Minecraft-esque chunks. The chunks are generated seperately using the Diamond-square algorithm.
The problem is that these chunks aren't lining up, they're completely seperate. I've tried a lot of things to…

How to implement the diamond-square algorithm?
I was reading this: http://www.gameprogrammer.com/fractal.html#diamond
And it says:
This is the starting-point for the iterative subdivision routine,
which is in two steps:
The diamond step: Taking a square of four points, generate a random value…

How to arrange faces of a quad sphere to simplify neighbour lookup?
I'm working on a procedural planet generator that uses a quad sphere, or quadrilateralized spherical cube, to represent its surface.
Most authors seem to number and arrange the faces arbitrarily, and so did I. For example, this is the arrangement…
