Anybody willing to write a dot3 bumpmapping tutorial? I''ve downloaded the sample code from Apple and will be looking through it later on (I''ve already skimmed through it) - but Apple''s sample codes are usually very messy and poorly explained and I don''t think this one is any different. Another question re dot3; how does one make the cyan/magenta emboss texture that seems to be necessary in addition to the bumpmap texture? Can this be done by ramming a texture through a standard series of Photoshop filters? C Lund

You could do it with only standard filters in PS, but because it can''t normalize, it won''t work.

So instead, use this:
http://developer.nvidia.com/view.asp?IO=ps_normalmapfilter

http://users.ox.ac.uk/~univ1234/tutorials/simplebump/simplebump.htm

for your dot3 tutorial
I might write one for nehe''s code, but of got other things to worry about right now. I DID get it working with nehe''s base code, so that''s a start.

That looks like it could have been quite useful. Unfortunately, it requires DirectX8 to work (according to the readme http://developer.nvidia.com/docs/IO/1169/ATT/Readme.txt) and that''s not something I plan on installing on my mac..

I tried the plugin anyway, but it didn''t do anything. Thanks anyway.

This looks like what I was looking for. If nothing else it explains what the normal maps are. I suppose I''ll have to start by making an app that creates normal maps. It''s a pity Adobe charges for ASN Dev memberships or I''d have tired to write a plugin that does this. Oh well. Now to wrap my head around the tutorial. Thanks. B)

Even though you didn''t ask one, let me point out some sample source code for normalization cubemap here. I don''t really know if you need it.

Though, I know that you need a normal map generation, and I''ve copied one from Mark Kilgard that I''ll post a bit later if you wish.

Ok, you can find the article at developer.nvidia.com and in the end of the document there is source code for things such as normalization cubemep or normal map generation.

vincoof; thanks for the links. I''ll be spending a lot of time with the stuff there.

Another good link.
