mobRotate
Mobius transformation applied to the given list of objects of the complex plane
induced by the rotation of the Riemann sphere, with the stereographic projection of the
given complex point as axis, by the given numeric angle (in radians)
constructors:
-
mobRotate
(zpoint, float , [list of objects]
)
-
mobTransform
(zpoint, float , [list of objects]
)
Methods defined in mobRotate
Methods defined in _zTransformation
Methods defined in Element
length of the iterable assocaited with the object
method that is called on change events, calling reoutines to find current
position based on dependecies, current visibility status, etc.
each object has a 4x4 matrix associated with it, representing the object's axis of
rotation and translation from the origin. Needed for the implementation of the
Projection class. Set to the identity matrix by default.
test whether any Elements on which there is a dependency
have become 'null', i.e. not calculatable - .e.g, imaginary when
working within real space
check for change in visibiliy status and toggle
visibility as necessary, reset change flag to 0 on
effectuating change in visiblity
toggle the 'null' flag, indicating whether the current postion of the
object's position is visible - e.g. is real when working in real space
f
_setnull(self, to_null=True)
...
set object and the objects dependant on it to 'null' when
its position cannot be made visible- e.g. imaginary when working in real
space.
Routine to return Element to intial position.
Default is to run update routine
method to be overridden to erase loci of objects that are traceable
method to be overridden to erase curves traced by point objects
Methods defined in zdrawArray
iterate through the objects of the array and call the objects _redraw routine to redraw
at its current position
the objects of the array get initialized on creation by the array's init() method - this is only
to mark the array itself as initialized
export the objects of the scene's arrays to PovRay SDL
