The bump mapping shader thats not too complex and just looks amazing

[Xetick]

I have been looking for that shader that 'everyone' seems to be using that just make objects look so good. Finally I do think I have found it.

Example of a torus knot without any bump map applied


The same with a noise bump map


So whats so special with this algorithm. For one it looks very good. It's also not too complicated but more specifically it doesn't need any tangents to work. The noise applied in my example is just a real time noise height field generated in the shader. This can of course be any texture or function something that is incredibly useful.

The shader and example program with source can be found on mikkelsen's blog

Thanks for finding this tutorial, even i understood the process behind such beautiful effect

wow, I am working on bump mapping too. 10x

Nice find there Xetick - Thanks for sharing it with us

The bump mapping looks really excellent.

Good one. Thx for sharing!

Well done

Looks very nice Xetick. I shall have to try and implement this

I played around with it a bit more and got the image below. The whole scene is as usual all generated procedurally. The name of the lighting algorithm is Torrance Sparrow with the addition of the normal adjustment linked to at the start of this thread.



Physically based lightning can obviously make all the difference!

Nice!

Xetick, that looks lovely! Like chiseled stone.

I was going to say that it looks like a stone sculpture too but Raizor beat me to it.

It looks awesome.
