"Does anyone know anywhere to get good tutorials on parrallax mapping?"

Hey everyone, im researching into mapping techniques and texturing techniques for my game environment, im a grad student at Portsmouth University in the UK doing computer animation and im making my final uni project.

Anyway.. to the point - Does anyone know anywhere to get good tutorials on parrallax mapping? I can normal map, thats a doddle, but i cant find anything on how to go about learning parralax mapping, im using 3D Studio Max and Photoshop.

Any assistence would be great, thanks!

what exactly do you want to know about parallax mapping? there are no real tutorials about that.

Parallaxmapping techniques usually use a simple heightmaps but often additional maps(which are computed in an offline process) to make the algorithm faster(at least that's how it's done for games). There are algorithm that work also without additional maps like POM(parallax occlusion mapping),relief mapping(IIRC) or offset bumpmapping(this is veeery inaccurate though)

Some algos are:
POM
Relief mapping(with maany additions,like curved relief mapping)
offset bumpmapping
CSM(conestep mapping(search the forums on gamedev.net))
...

You said that you want that for a game environment,so why don't you post that on a game development forum?(gamedev.net)

anyway, i hope that helped

Hey m4gnus thankyou for your reply.

Im basically just trying to get clued up on different mapping techniques, I have heard about parralax mapping, but if im honest i dont know a great deal about it or how to employ it, thus went about doing the initial most obvious thing to my mind, and look for some tutorials. I guess I should read up on parralax mapping, and then go about trying to implement it and learn the details of it. Thanks again i may post on the gamedev forum and see if that brings me any luck also. Thankyou again
