Not so impressive video..but why so few colors?

[mrrgu]

Hello

I did this rendering through the Mandelbulb, slice by slice 600 iterations per slice and displaying result every 10th iteration.
Displayed the result with colors r g b mapping directly to (x, y, z) from the iterations.

Question is why so few colors and no blue??
Do this mean the vectors are escaping only in certain directions ?

Flickering at least I can explain that is orbits that do not settle.


Video is kind of slow..so you should move forward..

Can no one explain this ?

assuming you get last iteration point for color mapping, try:
(r,g,b) = (kx*abs(x), ky*abs(y), kz*abs(z)), where k ~0.1 ~0.01 ? maybe some shift?
abs for situation if z values are always negative. i don't know if it's possible, but thats probably yields no blue.

I made the same experiment but I have completely another result. Please look at attached picture. There are all 3 colours (R=x, G=y, B = z), also blue. Colours are smooth - it means that vectors are escaping in every direction (not quantised). I think you have some bug in program and colours are clipped.

Nice picture Buddhi

Ok sorry!! My mistake had alpha blending turned on! it made the colors dissapear!

Now it kind of matches Buddi but in lower resolution.



To the right is (theta,phi,z) for debugging..

note temperature outside to the top right..must keep Computer working to get a good temperature in the apartment..bad insulation
