## triangle alpha-beta-gamma, where alpha+beta+gamma = 360/k degrees
|
|
##
|
|
## You can change alpha (=360/k deg * a/3), beta (=360/k deg * b/3), and k using 'tessellation sliders' in the geometry experiments menu.
|
|
##
|
|
## Changing k reloads the map, while changing other parameters does not
|
|
##
|
|
## Note: the spherical version (k=1) is buggy
