Infinite 3D heightmap landscape

someone mentioned generating a landscape so I wrote one for 3D height maps with perlin noise :). Point your iPad in the direction you want to go. need to add some shader code to make visibility shorter. and need to make it faster, quite slow now. Is cullface supported yet?

I think culling is automatic, I had a play with the other one it’s great!
Edit: doesn’t matter tried it out, good job!
