Re: Bullet + Ogre: Making holes in a soft body

Ok, so I've made progress in that I'm able to recreate the OGRE mesh from the 'refine'-d Bullet soft body by iterating over the Bullet faces list for the triangle indices (my texture co-ordinates are a mess but that's another story). What I'm thinking now is since Bullet doesn't maintain contact poi...

Re: Bullet + Ogre: Making holes in a soft body

Update: I just realized something terrifying as well as sorta fun :lol: . When you use the 'refine' function of a Bullet soft body to cut it, the vertex and index list change (well duh :roll: ). Now as far as I can tell, OGRE and Bullet don't follow the same pattern of specifying triangle indices. ...

Bullet + Ogre: Making holes in a soft body

Hi I'm currently working on a surgical simulator and am using the OGRE engine for rendering and Bullet for the soft body physics. I was looking into mesh cutting. For testing purposes, I've imported the surgical tool mesh and made it a kinematic body and the organ mesh as a soft body. After looking ...

psb->scale(btVector3(...));

I just tried it, it should scale both the Object Node and the Softbody
Hey, works like a charm. Thanks a lot! :D

AppSoftBodyDemo: How do you get the cloth to tear?

I noticed in the below video that soft body deformation is possible in Bullet vis a vis the cloth tearing.... http://www.youtube.com/watch?v=exss517n1I0 I've been through the demo code more times than I care to recount and I cannot, for the life of me, figure out how they got the cloth to tear. The ...

Re: btSoftBodyHelpers::CreateFromTriMesh - Ogre version?

I scaled down the model in OGRE using mObjectNode->scale(...) where mObjectNode is the scene node of the soft body's corresponding OGRE entity, but when I run the program and I switch on the debug drawer I noticed that the entity has been scaled down but the collision shape hasn't. Does anyone know ...
