I too found the errors but cant get any of this to work. There are too few good examples online, it would be nice to get one working

Hey. Just found this. Came across iq’s stuff a while ago, but being a noob I couldn’t do anything with it.

Then while rediscovering GLSL & iq’s website, I found this awesome resource!

But here’s the thing, I can’t get it to work. ;o)

I eventually found 2 errors in the code. Here are the fixes:
line 97: d.x-distance_to_obj(p-e.yyx).x); // had an extra “)”
line 98: N = normalize(n); // was missing “;”

I’m trying to use GLSL Hacker 0.6.0.0 & Blender 2.69 using this tutorial:

Any help?
