Elastic Deform: Integrate Grab Kelvinlets
Needs ReviewPublic

Authored by Pablo Dobarro (pablodp606) on Thu, Oct 31, 5:10 PM.



This patch uses RK4 integration in the grab kelvinlets. In theory this is the right way to use them, but I think I prefer the old behavior when doing just a single evaluation for the grab brushes. Maybe there is something wrong with the implementation.

Not sure how we should proceed with this patch? So perhaps have more feedback from users.


we should add a the link to the original paper and add its name as numbers may get outdated more quickly and does not tell us a thing


so grab_delta is not a delta, but a direction. or this is something to investigate or use the correct namings.

The Grease Pencil Team was also interested in these brushes and the Kelvinlet formulas are the same for mesh sculpting and Grease Pencil.
@Antonio Vazquez (antoniov) Maybe we can take a look at this during 2.82, move the Kelvinlets to a place where can be reused in both sculpting systems and check if everything is correct?
