Incorrect Hand-Object Contact #16

Closed zhangy76 closed 8 months ago

zhangy76 commented 8 months ago

Hi,

Thank you for sharing the great work! When visualizing the data, I obtain incorrect hand-oject contacts as the examples shown below: 1 2

The hand and object mesh are obtained from the MANO hand data (pose, shape, global rotation, translation) and object data (object template, object global rotation, translation). I wonder if there are errors in my visualization process or the data can include these errors?

hi i've solved this issue. I applied the translation and rotation matrix directly to the vertices of the object(rigid body), rather than applying the matrix to a center of the rigid body. I think it is because the "center" is inaccurate.
