poincare_disk

Arguments:

  • _size>=0,_p>2,_q>2,_angle,_tiling={ 0:Triangular | 1:Polygonal },_nb_max_iter>=0,_xmin,_ymin,_xmax,_ymax

Description:

Return a 3-channels image of a poincare disk. Output channels are [x,y,it].

Default values:

size=1024, p=5, q=3, angle=0, tiling=0, nb_max_iter=20, xmin=ymin=-1 and xmax=ymax=1.

Example of use:

repeat 4 { poincare_disk 1024,{3+$>} channels[-1] 2 mod[-1] 3 neq[-1] 2 } rescale2d 50%
