Hi:
Yes, with noncircular its always possible to clip, the user has to play with things such as width and such to
ensure its a match that will work. The reason for this is that to tooth a noncircular gear is a subtractive process
and one that used the second derivative of the generating formula. Unless I use a very small derivative step
which would take a very long time to calculate , the possability fo overlap can occur, Gearotic is balanced between
speed, complexity and accuracy.. over time each is tweaked as versions show weaknesses on eother side.
Its kinda like trying to figure out the perimeter length of an ellipse, sounds easy but its actually a derivative
function that has no answer, the longer you calculate it the closer you get.. so in the end some things will always
be a mathematical compromise between speed and accuracy, I figure no-one wants to wait an hour for toothing
when moving to a .48 width can fix a firly well represented answer.
(We'll discuss this more in the next module release..which while easy to use I think, is easily the most complex
gear module to be put in the program.)
