The origin/author of parallax mapping

[Reverend]

IIRC it comes from a few Japanese engineers and there was also a paper by them (a careful and extremely time-consuming search here seem to point to a hardware implementation via a shader in the OpenGL.org forum but my memory says it was proposed before that) . Can anyone provide me the link to that paper? Thanks.

The first time i heard about it was from terry welsh who posted it at opengl.org and later published the paper Parallax mapping : A per pixel approximation of uneven surfaces 2004

Yes this is it, thanks.

I almost thought Humus invented it
remember its demo, and the engine from Artificial Studios which used the same (free) textures to show their parallax mapping?

Well, Terry Welsh seems to have reinvented it. If I recall correctly, he has found the japanese papers only afterwards, as he was searching for existing implementations of his idea. I still remember his post on opengl.org, were is coused real enthusiasm

So I tend to call him the real inventor of parallax mapping, as his work coused the spreading o fthis effect.

p.s. This is a clear proove that new things can be still invented

I jumped on the trend pretty quickly, but Terry Welsh was definitely before me, and I learned the technique from his posting at opengl.org

you maybe interested in this other method, Cone Step Mapping. It is being discused in gamedev

I was writing up a paper too

I posted this in 2003 (which I believe was before the original opengl.org thread),

effectivly closer to occlusion mapping than actually simple parallax mapping. Although highly limited by my radeon 9500 at the time, using 5 iterations.

I eventually came to the conclusion it just didn't look good enoguh for the performance hit and concentrated on my stencil shadows paper which got published the next year.

Ohh well

Clever shaders are evolutionary, not revolutionary.
