PBD Thesis: They introduce a cloth system based on constraints rather than springs to keep particles at a certain distance.
V Master Class:
Vellum solver is continuation of old grain solver. Vellum is hardware accelerated system and uses GPU for computation. Vellum is Integrated Multiphysics system= can define more than one type of constraints
Vellum is also point based system
The vellum constraint outputs two type of constraints namely bend and distance. Bend takes up 4 points whereas distance takes 2 points. Distance constraint take those two points and makes sure they stay at a certain distance (restlength). Bend constraint refer to 4 points and make sure the angle between the two triangles or dihedral is at a certain angle.
Bend and distance for Cloth
Bendtwist and stretchshear for hair
Pressure constraint for balloon
Strut constraints creates lines which has distance constraint for softbody
Cloth i/o (similar to dopio but for vellum) saves into two: geometry and constraint
V Drape Masterclass:
Entagma: Sub steps and constraint iteration = helps in better simulation outcome
What is PBD?
How Vellum Works?
Types of Vellum Constraint?
SOPS and DOPS Vellum and their differences?
Order I want to try: Cloth, Soft body, Hair, Grain
