load other YCB object #3

Open shivanimall opened 3 years ago

shivanimall commented 3 years ago

Hi @eleramp

I am trying to load other YCB objects than the ones you have, and I am wondering if blender v-hcad is the only option to generate the collision_vhcad files? I am facing some issues with blender v-hcad geenration. In particular I am urgenly in need of wood_block YCB object (036_wood_block)

Thank you

Hi @shivanimall a possibility could be to directly use pybullet, which has a script to generate the vhcad decomposition here: https://github.com/bulletphysics/bullet3/tree/master/Extras/VHACD/test/src

It converts convex triangle mesh in an OBJ file into a new OBJ file with multiple convex hull objects.

Otherwise, if you don't need realistic collision detection, you can start by using the same mesh file both for visualization and collision.

thanks for the response @eleramp will try out and update.

@shivanimall, did you have any luck with this? I am also in need of the other YCB objects. Happy to lend a hand if I can.
