Title: Calculation optimal settings Post by: mario837 on August 11, 2011, 10:56:18 PM One of the sections of MB3D that produces me (probably to some others) the most confusion is the 'Calculation' settings.
The only clear variable to me is the DE Stop: lower it and you get more details. Increase it and the image begins to fatten in some way. So, the usual Menger3 you get with DE Stop=1 turns into sort of an irregular ball with this same value increased to 100. Now, for the remaining 7 values we have the help legends that gives some direction of its impact but no precise indication of when to check or uncheck one of them or the range which is the best compromise between quality and render time, nor the limit that some of them may have. On the latter, I have read recently that Stepcount for binary search is not very useful over 12 and Smooth normals doesn't need higher than 3. I include below an acronym of each so to facilitate reference. DES = DE Stop VoFOV = Vary DE stop on FOV RSM = Raystep multiplier SWL= Stepwidth limiter SBS = Stepcount for binary search SN = Smooth normals NDE = Normals on DE FSR = First step random Any idea wil be more than welcome!

Sorry for that! :o :D

Sorry for that! :o :D Yep, that was me in my previous life ^-^ All i can say is that i begin with high Stepwidth multiplier + limiter and decrease the multiplier until overstepping seems ok, on problem formulas like inverse thingies reducing the limiter also tested. On bigger pic i test certain parts also with postprocess->Recalc a selection and adjust these so that overstepping is just gone. All with first step random on to see the random noise. Normals on DE always turned on to get the normals of the surface, only if this seems to be a problem or for smooth effect turned off. *monk gif not found* :suspious: Title: Re: Calculation optimal settings Post by: mario837 on August 13, 2011, 09:32:43 PM The last person that knew the answer was an old monk, he lived all his life alone and died 500 years ago.

This is really impressive. DarkBeam seems to have privileged information of the real origins of the 'Mandelbrot Set'... or should we call it the 'Udo Set' to be fair? Anyway, that lead me to listen Carmina Burana. I always loved it!
