btSoftBody Mysteries
Posted: Tue Nov 20, 2012 4:07 am
Hello Friends,
I'm starting some studies about Bullet's soft body simulation. Since the manual has only two pages about it, I started to dive into the demo.
After simulate successfully some soft bodies, some questions arose:
- What is sparseSDF and it's role in simulation? I managed to understand that's kind of a graph, and it's used when a softbody collides.
- What is the "m" parameter in btSoftBody's constructor? All codes that I saw in the demo, its value is zero.
- Is there any way to reduce the size of the shape collision for each node in a mesh?
- What is the default mass of a node in a mesh?
Best Regards!
