Performance improvements for line shapes #197
Description
Is your feature request related to a problem? Please describe.
The performance of the line shape could be improved, as the performance is a bit slow compared to the circular shapes.
For some performance numbers (tested with cProfile):
python -m cProfile -m data_morph --start-shape panda --target-shape star
320361688 function calls (316213771 primitive calls) in 116.715 seconds
Compare with:
python -m cProfile -m data_morph --start-shape panda --target-shape bullseye
83940221 function calls (83300500 primitive calls) in 41.067 seconds
Seems to be a factor of 4 more function calls, resulting in roughly 3x slower performance.
Describe the solution you'd like
Faster evaluation of line-line shapes.
