Summary | 0027160: Weird results of the pipe algorithm | ||||||||||||
Description | The pipe algorithm produces a seemingly wrong result - the resulting surface is self-intersecting and has a U0 isoline (same as 2*PI) as self-intersecting in the beginning, although the path curve does not have such issues. Another observation is that poles are very far distant from the path. This is a regular observation on the pipe algorithm. Perhaps twisting and skewing has the same root-cause as in 0025426. | ||||||||||||
Steps To Reproduce | restore path.rle p tuya r p 0.2; fit #see fit.png clear r; mkface f r; isos f 20; wz #see wz.png uiso u0 r 0 #wrong isoline, self-intersecting cvalue p 0 x y z d1z d1y d1z d2x d2y d2z line l1 x y z d1x d1y d1z line l2 x y z d2x d2y d2z trim tl1 l1 0 1 trim tl2 l2 0 0.2 #see all.png, 1st and 2nd derivative seem OK without issues that might lead to self-intersections | ||||||||||||
