marching-cubes

I have implemented the Marching Cubes algorithm to display an isosurface based on voxel data. Currently, it is displayed with triplanar texturing. I'm working with unity, so I have a material with the triplanar shader attached. Now, the whole isosurface is rendered using this material. And thats my problem: I want the texture to represent the voxel data. I'm storing a material value for every point in the grid, and based on this value, I want the texture of the isosurface to change. Sadly, I have no clue how to do this. So if the voxel is sand, I want sand to be displayed; if it's stone, then there should be stone. Right now, everything is displayed as sand. Thanks in advance!

Textures on top of other textures when using VBOs

as seen on Game Development - Search for 'Game Development'
I'm currently making a cube style game. With chunks being drawn with VBOs. I'd like to know if there is a way to create an overlay texture on top of the existing texture without the need to rebuild the VBO. This is required to show activity in a cube (think of Minecraft when destroying a block and… >>> More
Texture switching with a entity system

I'm using thinking of using an entity system in my game. So far I've been using Artemis with success. However, I have a question about texture switching. I read that switching textures too often is bad. So I load all the textures when the game loads like so: import org.newdawn.slick.opengl.TextureLoader; … >>> More

"Marching cubes" voxel terrain - triplanar texturing with depth?

as seen on Game Development - Search for 'Game Development'
I am currently working on a voxel terrain that uses the marching cubes algorithm for polygonizing the scalar field of voxels. I am using a triplanar texturing shader for texturing. say I have a grass texture set to the Y axis and a dirt texture for both the X and Z axes. Now, when my player digs downwards… >>> More
How to speed up marching cubes?

as seen on Stack Overflow - Search for 'Stack Overflow'
I'm using this marching cube algorithm to draw 3D isosurfaces (ported into C#, outputting MeshGeomtry3Ds, but otherwise the same). The resulting surfaces look great, but are taking a long time to calculate. Are there any ways to speed up marching cubes? The most obvious one is to simply reduce the… >>> More
