END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

this forum will stay online for reference

@lenord:  This effect is not exponential scaled (for time consumption) in reflection depth, because it calculates only straight reflections (and some DEAO rays) and not do a full monte carlo simulation.  That would take maybe some month to render an image noisefree smiley

not really, the first perspective 3d mandelbulb images done by me in 2007 had fully unbiased global illumination, and that was before distance estimators were introduced.

i've been wanting to add mandelbulb/box support to indigo renderer for some time, but i'm still unsure how to handle (generate DE functions for) all these new formulae that're going around... because then it's easy to have it working with any kind of 3d scene, any materials, gpu acceleration, motion blur, networking, the whole lot smiley

It would be cool to implement those things (Bryce style);

- translucent / semiopaque / mirror materials (I know it's very hard,  undecided ) - the glow fx is already here (the fog wink )
- cloud field, moon, sun fakings (this is more fast I think, for the cloud field you can use sfbm + gnarly patterns? cheesy )

Cool, if not DE then did you used voxel space to render or fixed stepping?

My guess is for some hybrids and more special light options, it would take still a month or more for a fullscreen noisefree render (i am speaking just for me and CPU, of course).

The 4 point method is a very general DE option, but not all formula options gives valid DE's with it.  Don't know how to generate a more general one, beside of analyzing the DE's and make some kind of corrections for it... (just an idea)

All solved in 1.7!! And then you get reflections on top... Just for the fun of it, here's a version of my problematic parameter set in 1.7 . And yes, I had to add some reflections of course grin

Tks Jesse!
