Tight angles with extruder #18

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Using BezierPath in an extruder can produce visual bugs, especially when 
working with tight angles. A workaround should be found to make it look 
visually OK.

Algorithm idea:
- First, find the bounding circle of the shape
- Determine the intersection line between the two planes (last path point and 
current point)
- Project q*circleCenter3 on this line
- If distance from this point to its projection is > enclosingCircleRadius, no 
action taken
- Otherwise, shift v0 by the amount needed

Implementing the method described above gave weird results, because while 
translating shape, orientation was not updated.
Another approach to take:
- Let this function be a part of Path, so orientations are re-computed when 
extruding.
- Create a function in Shape/multiShape to find the smallest bounding circle.

Didn't work either... disabled feature and postpone to 0.3...
