You are ... absurdly wonderful

I never understood a word of this...

Another great script, Knighty.

I see you found a work-around for doing some of the work in the vertex shader :-) I'll add vertex init-hooks to the raytracers - it is a good idea. Also, you are right that thes pre-calculations should run on the host, but it would be difficult to implement. It would require embedding a dynamic c-compiler, and implement something like the GLSL matrix and vector classes.

Thank you Darkbeam and Syntopia.

It wouldn't be possible without the feature you provided to embed vs code
I don't think it is necessary to go for a compiler. An interpreter would be sufficient. Anyway, this is not a priority IMHO.
BTW, what happened to reflections in the last version's renderers?

Hmm. They were removed when I refactored some code. They will be put back in, but I need some more generic code to make them work with Image-Based Light.

Wow I love your work !!!!!  I like the spiral and the fluid bubble.  I am new and very beginner to fragmentarium ( I download the program and messing with it).  Can you give me some clues to how I can get a masterpiece like yours and even to animate it...

Thanx in advance

Ben

Download the .zip attachment. For animations, I fear it's not possible?

What if you were to replace each sphere with just a dot of light at the center?

[Syntopia]

For animations, I fear it's not possible?

Possible, but not as easy as M3D. You will have to base animation on the' time' variable in the script (place 'uniform float time;' at top of script), and use animation menu to export single images. Then use something like VirtualDub and HandBrake to create animation.
