Apprentice Piece by MakinMagic

An apprentice piece, not sure if it's wooden, imitation or bakelite

Created from one of my 3D fornulas for Ultrafractal - it's actually just one way of viewing the "Julibrot" for z^2+c (the original Mandelbrot set and Julia sets) in 3D (a complete Julibrot is actually 4D).

that's some impressive resolution you've achieved! i mean resolution in the 3d sense, not only the 2d sense - the fine/thin details are very well resolved.

about the lighting model, phong is just the sum of diffuse and specular terms, so adding is the right thing to do, and no one multiplies it

i'm surprised that this needs two passes though - can't you combine them in your script?

I think I rendered it at 4096 wide

The animation I mentioned I think is also 4096 wide and a lot of stages - hence it's taking around 460 hours on a 2Ghz P4.

It's possible to combine diffuse and specular correctly in one layer but only if you use direct colouring mode - the diffuse needs to be multiply but the specular should be lighten which you can't do in a single palettised layer, I intend to do custom colourings for my new 3D formulas which will open up a lot of new options.

this makes me even more interested to learn about your ray/fractal intersection algorithm - a simple gpu implementation (and i must stress simple, since it comes with all the texturing/colouring ops you'd need too - all with dedicated hardware support) would no doubt run realtime with moderate settings, and in a few minutes you could easily render something with really really high quality!

if you could send me a little email describing/referencing the algo you use i should be able to cook something up you can play around with!

Hi, you can get the algorithm from [link] it's in mmf.ufm as "Solid3D-Complex" and there's also "Solid3D" formulas for quaternions and hypercomplex too.
Having said that a better algorithm for GPU implimentation can be found in Ron Barnett's "reb.ufm" as his 3D raytrace formula.
The problem with the "Solid3D" ones is they're implimented in a rather non-optimum way due to the way UF handles transfer to the display (in order that you can actually see the fractal being rendered).

btw forgot to say, and this ties in with my post at fractalforums, any shader model 3 gpu will do for this - i have a spare geforce 6600 you can use in the worst case, but shipping it to the us will cost more than buying one new!

Awesome and excellent, rich and beautiful. Amazing 3D!

Thanks Linda !

very 3d ! nice work

MakinMagic Featured By Owner Sep 27, 2006 Hobbyist Digital Artist

Thanks, I'm still waiting for an animation of this to finish - it's been rendering in the background on my work machine when I'm there - 360 hours so far (around 20% to go).

good god! and I bet you have a fast machine too!

MakinMagic Featured By Owner Sep 29, 2006 Hobbyist Digital Artist

It's a 2GHz processor, but it's taking a lot of hours partly because it's running minimised in the background

just curious...do you use a pc or a mac for your graphics stuff??

MakinMagic Featured By Owner Sep 30, 2006 Hobbyist Digital Artist

I use a Windows PC, 99% of my fractals are created using either Ultrafractal or MMFrac which both only run at full speed on a PC as there's no dedicated MAC versions of them (MMFrac is actually DOS32 rather than Windows).

good to know, thanks!!

Unreal fractal, Dave/ I love the flow of its form. This is some neat stuff you've been doing - sorta like if XD and Apophysis were melded into one fractal type. Very freah and new stuff!

MakinMagic Featured By Owner Mar 5, 2006 Hobbyist Digital Artist

Thanks Rick, I'm enjoying doing the 3D stuff again, I gave up previously because the render times were so slow but it's passable on my 3GHz P4 - though I'd love to have say three or four networked

Very cool and very smooooooth looking fractal

MakinMagic Featured By Owner Feb 28, 2006 Hobbyist Digital Artist

Thanks - I got the great lighting by having the diffuse (Gourad) and specular (Phong) in separate layers, using the specular layer in lighten merge mode instead of multiply. This method produces better results than having just one lighting layer mixing the diffuse and specular components but obviously increases render time somewhat
