Public bug reported:
I tried to profile hugin on a large project with 500 images and 100000
control points. I identified and fixed some bottlenecks:
ImageVariable.patch - reimplemented ImageVariable with shared_ptr -
reduces complexity from O(n) to O(1)
ImageVariableGroup.patch - move some method calls out of a loop
GreatCircles.patch - reduce number of segments for short lines
GreatCircles-image.patch - HuginBase::SrcPanoImage is expensive,
initialize equirectangularImage only once
** Affects: hugin
