I'm working on a little alienshooter for some time and will try to generate landscapes with the Marching Cube algorithmus.
I've startet with dame volumen data from here: scull data

My first test creating a 3d model of that:

Another look in Wireframemode:

You also see the building time (<1sec) with the marching cube and the number of triangles (>300,000) generated.

Here is another way to build the volumen data, a so called wiffle cube out of a complex formula wiffle cube

I will use that for optimizing the mesh later on. I see the results better in that mesh i think :(

Today i tried the first step in texturing that model. I create a textureatlas 128*128*128 by hand (with my graficprogramm)

I think i can make better things using Genetica. Lets see how it wiil go on in the future.

Interesting images. Will the terrain be randomly generated somehow?

Yes !
Goal is to came up with something like this http: GPU Gems 3 :P
Not using GeometrieShaders because i'm developping with xna4. xna is limitid to DirectX9 ( GeometrieShaders came up with DirectX10 )
i'm happy when i end up to something like this : Lords of Uberdark

Will se what i can do.

Here is my first landscape. And all is done with Genetica. The background and the overall texture, but in the main the landscapemesh is done by a simple 3DNoisetexture addet a few times tricky together.
Next thing is to add Multi - and Triplanartexturing and adding some Effecttextures.

Addet a shader for triplanartexturing. Dosn't work perefect by now but i like to show a screenshot:

Texture is one of Geneticas presets ;)

Looks neat, it kind of reminded me of the floating isles in the movie Avatar.

Permission required to use my work. (Seriously!)
