Perlin Noise

I've managed to make a perlin noise script which puts a texture across my sphere. How would I make it so I can raise different colors? so black would be the top level and then lighter going down. I can't seem to find a tutorial on this....

 

Do you mean extrude/displacement, like

A terrain has a heightmap value, just set the texteure as the heightmap and you're done. Another option would be a mesh where you use the values as points in the mesh right away instead of the texture. This also gives you the option of making caves and holes.

 

Yes thats exactly what I mean, I have done a cube sphere with 6planes for the mesh but it can't seem to find any tutorials on how to make my terrain (perlin noise) raise up from the sphere.

 

Is they any examples you can show me so I can look through to have a better understanding? I've literally looked so much but not found anything they is ones where people have 'started and will keep everyone posted' but no more posts after.

 

some options with shaders:
- dx11 tesselate & displacement shaders (your perlin noise texture is heightmap) : http://docs.unity3d.com/Manual/SL-SurfaceShaderTessellation.html
- vertex displacement/extrude (see normal extrusion, using perlin texture as heightmap in vertex shader, but needs hipoly mesh) http://docs.unity3d.com/Manual/SL-SurfaceShaderExamples.html

or do you want to walk on the sphere and use collider on the surface, or its just for display?

tutorials,

• similar question, directly moving vertices based on perlin noise, instead of using texture : http://answers.unity3d.com/questions/571673/generating-a-displacement-map-in-unity3d.html

• using normal map it "looks" like having height : http://catlikecoding.com/unity/tutorials/octahedron-sphere/

• mesh deformation (could use texture as reference and move vertices) : http://catlikecoding.com/unity/tutorials/mesh-deformation/

 

Legend the last link actually is how i have my setup so that helps me loads. Thanks!
