Nice displacement...

[masterxilo]

Any chance we can get this demo or better yet, the code?

I want this...on minecraft lol

[UltraGigala]

reminds me of halo

Looks great and the tesselation isn't obvious.

[FrankDodd]

That's very nice, the texturing looks very good too.

[HelpMyFellowPeople]

this is amazing! Now we dont need directx 11

the surface is built up by marching cubes, the shorter the distance the higher the cube density, so I call it tesslation

the whole asteroid shape is defined by a 3 dimensional density field (advanced perlin noise ), not by pregenerated polygons ( or flat surfaces )

the "tesslation" is high enough to futher displace it by a displacement map, which generates the micro structure on the surface, i will add a wireframe video to clearly visualize whats going on soon, thanks for the interest btw

If this uses a tesselation algorithm, and is a flat surface, then it's not technically marching cubes, is it? Are there pixel-sized cube shapes in the shape of the landscape as it's tessalated or something?

[fimbo1234]

there is a base geometry generated by a noise field which is tesslated on the gpu with an added height texture, see the little craters on the surface, be sure to watch in HD, some more information here: surface.at
