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
