ISO Surfaces

[andreholzmeister]

A few years ago there were a plugin for VRay to create complex ISO surfaces out of procedural textures, it feels weird that nobody talks about this anymore, and that this feature is not present in most renderers of today...

Is it possible to have it on Corona? It is such a great feature and hard to achieve I believe...

Here are some examples of the past:

But is this a Shader ?

    Very nice and interesting ! :)

I remember that... it was a good one!.

The way that it was done by the Vray plugin, was a modifier, that interpreted the texture much like a shader i guess... I believe it is a very old feature in renderman, it works like a boolean shader, I always tought it was just achieved by a shader, but when I was searching for it a few days ago, I found that there was a modifier involved... Mentalray had one too called solid volume, here is an old example: http://www.maxforums.org/threads/_mr_solid_volume_shader/0001.aspx

The mentalray one looks like it was done only by the shader itself... I saw something

Some ancient POVray stuff too http://home.no/t-o-k/povray/Isosurface-Rotated_Noise.jpg

I found something about cinema 4D too, but cant find it anymore...
