Using a bumpmap for a planet sphere
Hello,
I have created a small universe with some planets, I am using Omega headers
(made with Clooties headers) for DX8.1
I have different planet textures and use them on a sphere,
the sphere is an X File. It looks good but perhaps could look better...
What type of bump mapping is it where you have an extra texture that is black and white and is used like a heightmap or something (for bumpmapping)?
Are there any samples about this matter? Or Tutorials or something?
I want my planets to look more 3dish, perhaps somebody can help me with that,
thanks!

Although I'm not sure it holds for the DX8 SDK; the DX9 SDK and up contains a sample that does just that (showing earth with a bump map). It is called BumpEarth and I think it is your best resource! Greetz,

Are you thinking of Parallax Displacement Mapping? I've used it via shaders and I must say the results are quite good! But even otherwise just plain ol' Bumpmappins is good enough provided you generate the normals correctly (use the DDS plugin for photoshop - it has quite a number of things you can tweak).
Hello,
it should also work on older cards, so I'll try Dot3 Bumpmapping, not Displacement. So I'll take a look at that BumpEarth sample...
Too bad I don't have photoshop. Now I need something to make a DDS map out of my planet texture...
Thanks for your help!

Hello,
Look at the DirectX utilities - there should be a texture tool - that will do what you want!
