Let’s start with Dual Marching Cubes

After having nicely textured Marching Cubes geometry, it’s time to start with something better, Dual Marching Cubes. But at some point, Marching Cubes will play a role again, hence the name Dual Marching Cubes.

A small introduction to this algorithm is now online.

Away with the white triangles!

So far, the triangles are plain white and boring. But now, they get a nice and realistic look with triplanar texturing with normal mapping!

Putting it all together, it’s now possible to draw actually volume terrain, but not very efficient (yet).
