bump mapping

Does Vizard support bump-mapping now?

Hi,

Bump mapping is a very general term. What kind of bumpmapping are you referring to? Vizard does support DOT3 bumpmapping. Other kinds of bump mapping can be implemented using plugins.

[cade_mccall]

Ahh. Well we've done bumpmapping in 3Dmax and we're trying to export the bumpmapped object as a vrml. Do you know if we can do that?

[farshizzo]

The VRML format does not support bumpmapping. You will have to do it manually in Vizard. I can give you some sample code of how to do it in Vizard. The method Vizard uses requires a normal map. Let me know if you would like to see the sample.

[cade_mccall]

Yeah, Farshid, some sample code would be crackin'.

I've attached a bump map demo. As I stated earlier, you will need a normal map and a diffuse map. The diffuse map is simply the regular texture map you want to apply to the object. The normal map is a texture which defines the normal at each pixel location of the diffuse map. You will have to generate this yourself. I'm not sure if 3dsmax will create it for you.

I'm really interested in bumpmapping, but this demo doesn't work for me. When I apply the bumpmap the planet no longer renders.
Is there a plugin I need?
I can multitexture by replacing

planet.bumpmap(norm,'',0)

with

planet.texture(norm,'',0)

any help is appreciated :)

I believe you need a graphics card that supports pixel shaders. In the nVidia world, this means a Geforce4 or higher. These days this sufficiency is pretty much a given. Could this be the cause for you though?

I have a Radeon X800 XT, I'm assuming that's not the issue.
Drat, I really want to bump map my textures. :(
Now I'm frowny.
