I'm experimenting with additional light-sources. During testing efficiency of shading algorithm I rendered image with 40000 light-sources distributed inside Mandelbox. Each light cast shadow and is rendered with specular effect. Rendering time was 1h 45min. Below is result.

I don't understand where are the 40000 light sources. I can count about 70 on the picture. Is it because it is a zoomed view?

Very nice!
Did you calculate 40000 dot-products for each pixel?
Think that would be too slow...

Yes, there was calculated 40000x2 dot-products. x2 because there are also calculated specular reflection effect. Most of light are invisible because are out of screen or covered by Mandelbox structures.

looks great cheesy
I guess, they're distributed randomly, right?

  It's only a matter of time before a tron-like Mandelbox videogame...

  Makes me wonder if Nethack type video games, or even Diablo 3 (newest nethack type- or should I say newest Omega type (the best roguelike ever)), use fractal level generation algorithms.  I suppose I should remember....

  Awesome job.  In another 33 years you will be creating the greatest video game ever: an evolving fractal universe that changes variables dynamically (such as scale, rotations, etc.) on the quantumbox, in which various fractal based spells (algorithms) will be used to attack other players by altering specific fractal parameters to disrupt their patterns.

   In another 5, I will do that in my mind, with various natural quantum fractal algorithms available to humanity at the moment (which outmatch our current silicon based computational algorithms by google tetrated to the google order of magnitude). 

  Speaking of which, time to make a tetration formula for ChaosPro, if there is not one already.  Image will be posted when done.  2d first... then 3d.  cheesy

I don't understand where are the 40000 light sources.
I can count about 70 on the picture.

Depends on where all of those lights are pointing to, and whether or not multiple lights are pointing to the same area.  Then again, were all of the lights turned on??    grin

And I thought Disco was so out of fashion.

It does remind one of the old mirrored ball reflecting splashes of light in multiple directions.  But with 40,000 small mirrors, that is what heck of a "disco ball".    grin

I do like the effect of the image.    smiley

Because you don't believe me that there was 40000 light sources, I have rendered some another image with Mandelbulb. Now there are 10000 light-sources but distributed much more dense and very near fractal surface. Rendering time was 1h 35 min

Result is nice, like a piece of crystallized carborundum (dark with colorful reflects).
Distribution of light sources seems random. Is there any possibility to distribute them following the shape and its recusivity ? A mandelbox could become a gorgeous sci-fi giant city/cruiser/space station...
