Implementing A Position Based Cloth Solver From Scratch

- Position Based Dynamic effects are quite popular today as these provide us with fast, predictable and stable simulations. Houdini comes with PBDs packaged inside of the "Grains" node and with H17 with XPBD inside of the vellum solver. This video shows how to implement one of the ancestors of the PBD technique. The idea comes from an aritcle on gamasutra called "Advanced Character Physics" www.gamasutra....
By implementing this Verlet based cloth solver we gain quite some insight in the principles behind Position Based Dynamics.

Great! Love this “behind the scenes” type of tutorial.
Thank you a lot!! I've been learning HOUDINI for not very long yet, and don't have any idea how people created CLOTH before VELLUM had appeared.But now I understand more with your help.
Awesome breakdown! Really wonderful information here, thank you!
Hi sir, ill just want to ask you, if for example i will do a rope simulation with 5 particles, do five particles need to calculate all the force on each particle?
