- Here is a proposal for another way of picking colours in
- escape orbit type fractals:
-
- For every pixel
- If NOT coloured
- Do Until ( maxiter OR escaped )
- [Begin Proposal]
- calculate distance of calculated point z(n+1) from z(n)
- set colour of z(n+1) according to calculated distance
- [End Proposal]
- Done
- EndIf
- EndFor
-
- This is essentially an escape velocity representation of
- the orbits. Yet another variation would consist in giving
- all pixels in the orbit the same colour as the last pixel
- of the orbit.
-
- There is also an interesting way of generating the image
- in slow motion:
-
- Do Until ( maxiter )
- For every pixel
- If ( ( NOT escaped ) AND ( NOT coloured ) )
- perform just one iteration
- [escape velocity colouring would fit here]
- EndIf
- EndFor
- Done
-
- Enjoy...
