After more than a year of reworking established combinations and using those discovered by others, I finally stumble upon a variation on an existing pairing worthy of mention. The interaction between the JuliaN family and the circular family of variations is well-known (particularly disc, rings2 and lazysusan), although the combination with ortho is less explored. But a chance encounter set me to looking again – it wasn’t until I employed ngon on the final transform that the real magic began.
Using ngon with sides = 4 but power = 0 rather than the default 2 contains the pattern to the central square instead of spreading it outwards (with power = 2 and sides very large, ngon behaves as spherical). The base pairing of ortho and julian began with variation amounts and triangles at their default unity but with the ortho transform weight increased to 30. Much can be explored by varying the ortho_in parameter and rotating the triangle. The essential innovation began by reducing the ortho variation amount whilst simultaneously increasing the size of the triangle – what happens is that effectively, a ‘frame’ appears, that is the outer portion of the square remains unaffected by the rotation:
Linking the ortho transform to another (lazysusan in this case) provides further interest:
Serial-linking that to whorl (with suitably-adjusted whorl_inside parameter) gives a texture reminiscent of combed oil-paint:
Switching attention to the ngon final and taking the power negative effectively ‘extrudes’ what was the frame into a ‘tunnel’:
And going further:
