needs more recursion!

blocks decompose into blocklets, blocklets into grains, grains into dust.

EDIT: Wait just another bad idea by me - lol. This is discontinuous but I didn't notice because I used it with the original frag which is somewhat symetrical.

Here is a "simple" optimization that should get rid of 7/8 of the blocks but due to parallelism it doesn't come close to that speed. For high numbers of blocks I saw a slight improvement in speed.
Code:
	float sx=((p.x<=0.0)?FragmentsX/2:0);
	float ex=((p.x>0.0)?FragmentsX/2+1:FragmentsX);
	float sy=((p.y<=0.0)?FragmentsY/2:0);
	float ey=((p.y>0.0)?FragmentsY/2+1:FragmentsY);
	float sz=((p.z<=0.0)?FragmentsZ/2:0);
	float ez=((p.z>0.0)?FragmentsZ/2+1:FragmentsZ);
	for (float x=sx; x<ex; x++) {
		for (float y=sy; y<ey; y++) {
			for (float z=sz; z<ez; z++) {
It just chooses the octant to check. Always keeping the middle layer. Whatever speedup is gained seems lost in compilation time smiley

Nice work eiffie, thanks! I saw your post earlier but only tested it today... I don't know what you think is a "slight improvement", but it renders a lot faster for me.

The problem is with the randomize option, but it should be a way to avoid the issue...

I attached the optimized frag, just don't use it with randomize.

I think the best solution is ray TRACING to the boxs then using distance estimation from there - but the scripts get more complicated that way. I've been cheating and using OpenGL's poly rendering to do the trace then there is almost no limit to the number of pieces. I still haven't tried cutting the fractal fractally but I will when I find time. Thanks for sharing your ideas and pics!

You are welcome eiffie, thanks to you for your interest and your help.

Btw, I'm having trouble implementing the optimized version of fog shadows in Fragmentarium. Everything seems to be ok, except it does not work ok grin
I had no problems with the buffer, the shadow map seems to be generated ok, but I think the conversion from sphere to screen coordinates is the problem.
I'll try a few more things, and if I can't do it I'll have to ask for your help  smiley.

P.S.: I'll have to delete the "Iñigo Quilez didn't accept me on Facebook" comment from the .frag, he just did  joy

Spent hours working on a fractal and you don't like the final result?

Ever thought of smashing it and breaking it to pieces?

Don't waste your money on a 3D print only to violently express your frustration!

And you don't have to use that hammer on your expensive monitor anymore!

I have the solution:

<a href="https://dl.dropbox.com/s/scxoucnt9nfjw5b/fragmentest.swf?token_hash=AAH6vay72NzJ6WPuJuYpJ2eqrfemn-TLaACHZJAvUEghrw" target="_blank">https://dl.dropbox.com/s/scxoucnt9nfjw5b/fragmentest.swf?token_hash=AAH6vay72NzJ6WPuJuYpJ2eqrfemn-TLaACHZJAvUEghrw</a>

Download the .frag, replace the formula section with that fractal you hate so much, and enjoy the fractal rage!


Genius!
