Can we visualize an arrow?

[keiohta]

Hi author, thank you very much for your continuous help.
I would like to visualize an arrow as the attached picture (Fig.1 in UMPNet paper [Xu, 2021]) to show force direction, but am not sure what's the best way to do that. I think one way is to load a URDF of the arrow and change its position and orientation when taking a picture, but I haven't found a good arrow model (found one but not so good). So, could you share your thoughts on how to visualize this kind of arrow?

Thank you in advance!

Since arrows are not articulated, you can just add a static/kinematic actor with a visual shape arrow attached (see documentation on adding an actor). You can generate arrows with code or draw one in modeling software.

@fbxiang thanks for your comment. I followed your advice and successfully implemented the arrow using the static actor. Thanks!
