Too kind words, Sabine!

I won't follow this exact way; it's really ugly to calculate that halfway clean (or touches the borders of M3D where I need to use the standard DE variants etc).
But who knows - a more smooth, straight and systematic way of mutation may be something interesting

Sabine62 In reply to gannjondal [2017-02-01 21:08:42 +0000 UTC]

We have standard DE variants??
Where can I find them?!!

And always very welcome, Gannjondal!

Ahh, you have really made too much with Fragmentarium, Sabine
I only mean that in M3D you have to choose the .DEOption - which chooses both the used tab, and the DE variant (means you can't write your own DE).
And if you really want to compare the DE calculation - well, also M3D is now Open Source

Ohh indeed I was thinking fragmentarium where you must code the DE as well! And though I do understand the general theory behind distance estimation, I really have no clue how to put it to work, as every type of formula has a different DE. There really is a big jump from a mental picture of estimating distances to points making up the object for rays to a line like return r2 / Dd; or return (0.5*(sqrt(0.1*r)))/(abs(DF)+1.); or return abs(0.5*abs(p.z-Offset.z)/DEfactor-DEoffset);. I can follow the variables through the code, but can't for the life of me find out WHY the return for a certain kind of formula has to like like it does :rofl; There's a whole bunch of theory between the general idea of DE and the actual needed code and I cannot find any place that has information about it...

And yes, mb3d is open source, but I am pretty sure from what I hear that the most interesting bits are hardcoded in an assembler-jungle and as a true programmer Jesse couldn't be bothered with clarifying comments in the code

That formulas look indeed somehow hand-optimized
If you have luck there is anywhere a thread in FF - or you must enter the brain of the original developer
And of course, it's not always trivial to conclude from a vizualisation to the actual formulas.

But it's both, a con, and a pro of Fragmentarium.
With M3D JIT I'm completely dependent from the available very few DE variants - and that can become very ugly quite fast...


And you are too hard with Jesse. There are comments within the code. Sometimes

I have searched but not yet found anything really useful. DE-guidelines need not be Fragmentarium-specific. DE does not have a lot to do with the available raytracers, neither with the program itself (which is more or less just a (rather luxurious) IDE to explore your own formulas or those for others). And per formula you must code a fresh DE that works for that particular formula. It's really nothing like mb3d or any other program I know. I even tinker with the ray-tracers (where I am even more monkey at the keyboard ) :}

Comments&code All hail Jesse - All hail Jesse!
