Parallax Mapping!

Well I was messing around with Irrlicht, and saw this demo:

It looked REALLY awesome, and I think Ogre should have some sort of Parallax mapping, its WAY better than bum mapping, IMO.

It's already (a long time) supported, just make the appropriate shader for it

For example: http://www.ogre3d.org/phpBB2/viewtopic. ... ter+shader

There it is again, we really need some more demos I think

It's a plain shader, in fact, the Irrlicht one doesn't do any type of occlusion. Plainest possible parallax mapping ever. Look at Demo_Grass for a "sample" parallax shader in Ogre.

There's already one in the demos. Open Demo_BumpMapping, change model to the head (or the knot), then change the material a few times until 'Offsetmapping' comes up.

For info, Ogre was one of the very first engines to demonstrate parallax (offset) mapping, before Irrlicht and even before UE3

As others have said, it's getting a bit old now, parallax occlusion mapping is better and you can even have self-shadowing on SM3 hardware. Read ShaderX or GPU Gems.

hmm thats weird.. i cant seem to find the bump mapping demo, is it in the OgreSDK package? or do I have to download the demos?

It's actually called Ogre_Dot3Bump

... or you can just look at the grass demo and need not to worry about changing materials
