Varying composite shapes?

Discussion in 'Modeling' started by ac-93, Apr 17, 2020.

  1. Hi all,

    Is there a method for creating composite objects with shapes outside of the box/cylinder/capsule range?

    Looking to create a hemispherical shape.

    Thanks
     
  2. Hi,

    I have a similar question. I'm trying to implement a textile which geometry is predefined. That means it is flat but not a rectangle. Is that realizable?

    Thanks
     
  3. You can use your own STLs.

    You first need to create a mesh asset of your STL (http://www.mujoco.org/book/XMLreference.html#mesh).
    Then you can create a geom with 'type' set to "mesh" (http://www.mujoco.org/book/XMLreference.html#geom) and then you specify a mesh asset by name:

    <asset>
    <meshfile="forearm.stl"/>
    </asset>

    <bodypos="0 0 0.35"/>
    <jointtype="hinge"axis="1 0 0"/>
    <geomtype="mesh"mesh="forearm"/>
    </body>

    There are some requirements to the STL, I have no experience with it myself.
     
  4. Hi Robert,
    thank you for your answer.

    I tried to follow you suggestion, but unfortunately I can't realize it. I imported the mesh, but the composite plugin doesn't give me the opportunity to setup the textiles geometry based on the mesh.
    Or did you mean the import of a rigid body with a stl-file?

    Best, Marian
     
  5. @Marian K. , my reply was for the original question from ac-93.

    I'm pretty you cannot create soft bodies from STLs. The cloth object is a network of bodies and joints. You could try to manually recreate this for a more free-form shape.
