    Programatically creating the bodies

    Hi, I would like to know whether it is possible to programatically (in the code) create parameterized rigid bodies in the world, not via...

  2. Xiya Cao replied to the thread Defining contacts and detecting collisions.

    Hello, I know how to do that! There is a number ncon which indicate the number of contacts. I can read the first ncon from the contacts...

  3. Xiya Cao replied to the thread Defining contacts and detecting collisions.

    Hi, I tried to print the contact info. It seems like some contacts are always in the list even though the two geoms are not contacting....

  4. Emo Todorov replied to the thread Computational effort weld constraint.

    Yes, there is a significant difference. You should always use a single body with multiple geoms when possible. Same goes for joints:...

    Computational effort weld constraint

    Is there a computational difference between having a body with multiple geoms and having a single geom per body, fixed together by a...

  6. Kyokushin liked Ethan Brooks's post in the thread touch sensor for contact between arbitrary geoms.

    I just returned to this thread and realized how completely unreproducible these code samples are, so apologies to Emo and the Mujoco...

  7. Kyokushin liked Ethan Brooks's post in the thread touch sensor for contact between arbitrary geoms.

    Ok. I have a minimal example that reproduces the issue: #include "lib.h" #ifdef MJ_EGL #include "renderEgl.h" #else #include...

  8. Kyokushin liked yongxf's post in the thread Comparing two methods for obtaining the contact force on the object.

    Hi, thanks for your reply. I have checked all the forces using the frame that you explained, and now they are exactly same. Actaully, I...

  9. Kyokushin liked Emo Todorov's post in the thread Comparing two methods for obtaining the contact force on the object.

    cfrc_ext is neither in the world frame nor in the object frame. Its frame orientation is aligned with the world frame, while its frame...

  10. Kyokushin liked Emo Todorov's post in the thread Contact locations on object.

    I am not quite sure about your indices... Anyway, I would do it using the built-in BLAS-like functions. Note that xmat is a 3x3 matrix...

  11. Kyokushin liked Emo Todorov's post in the thread Contact locations on object.

    The procedure you described is the correct way to compute the contact point coordinates in the local frame of each body. In addition to...
