sheaf	ced714987e	Implement adaptive shaving algorithm	2024-04-21 18:09:21 +02:00
sheaf	01fdd9a126	Improve robustness of quadratic equation solver ... Based on ideas from the paper "The Ins and Outs of Solving Quadratic Equations with Floating-Point Arithmetic" (Frédéric Goualard, 2023) Could still be improved further, but I think this is acceptable for now.	2024-04-21 14:19:37 +02:00
sheaf	1338d7ddbe	Improve intervallic rotation computations ... This commit bakes in a certain kind of representation for brush strokes: c(t,s) = p(t) + R(theta(t)) b(t,s) This representation allows us to cancel out some rotation terms when computing the envelope equation, improving the efficiency of the cusp-finding methods.	2024-04-20 18:28:41 +02:00
sheaf	2b167f594a	Make it easier to switch between 2 and 3-dim ... This commit makes it easier to switch between the 2-dim and 3-dim formulations of the cusp-finding problem. This is still work in progress, trying to improve the performance of the cusp-finding algorithms.	2024-04-18 21:33:55 +02:00
sheaf	0160081e80	Further modularisation of root isolation code ... The code is now generic over the dimension. There is a slight performance loss that I need to investigate; perhaps some things are not getting specialised? Maybe it is better to be more explicit about staging and splice in the functions with fixed dimensions.	2024-04-18 20:14:19 +02:00
