Hey everybody,

I've made a thread about dynamic terrain, but this will be specifically about voxel terrains. My sister and I are building a space exploration game with all kinds of planets to explore.

Nowadays is the hot trend to have fully editable voxel terrains (either blocks, or smooth). Now I wish to experiment with this technique but have absolutely no idea on where to start with in DBP.

The idea is to make a spherical planet shape with (smooth) voxels. Any ideas or suggestions on how to approach this?

Thanks!

It's pretty advanced stuff. You'll basically have to write your own renderer. You'll keep a 3D array to contain various points (like pixels, but with a depth value as well). Then you figure out, from a given point of view, what pixels are visible, where on the screen they will show up, etc. and draw individual pixels to represent these. For a decent engine you'll want transparancy and lots of funky things, but the basis is rendering that 3D array of points. Each element in it simplest will only have a colour. Start with that and see if you can get anything going

Sounds complicated indeed...

This looks like a mesh that's manipulated, but I do believe its a voxel rendering.

Can't something like this be done with meshes (with culling to remove unseen stuff)?

Al right, thanks Chris. I'll hop into that thread and this one can be considered as closed.
