Focusing point with camera
Opened this issue · 5 comments
When generating more complex scenes I would like to guide the user's view to the most important elements.
The demos suggest using
viz.viewer["/Cameras/default"].set_transform(<Some 4x4 matrix>))
viz.viewer["/Cameras/default/rotated/<object>"].set_property("position", [x, y, z])
How do you use these to move the camera close to an arbitrary position, such as (10., 0., 0.) and look at this arbitrary position?
The set_property seems to be able to reposition the camera (in the three js system where "up" = z_meshcat = +y_three_js and z_three_js = -y_meshcat). The camera seems to keep focusing on the origin. How to do you change the position the camera points at and pans around?
Hi @kingjin94 ! I have an open PR about this: #109
Great to hear that it is not just a problem of understanding the available API 😅 Is there any way I could help to expedite this PR?

I'm not sure. The maintainer seems very busy and maybe would like some help to look at PRs and merge them.
@rdeits, are you open to onboarding some folks to help maintain meshcat?
Hi all,
I see that the pull request #109 has been merged. But in my code if do something like:
viz = pin.visualize.MeshcatVisualizer(rmodel, collision, visual)
viz.initViewer(loadModel=True, open=True)
viz.setCameraPosition(np.array([0.6, 0., -0.15]))
viz.setCameraTarget(np.array([0., 1, 0.]))
then setCameraTarget does not change anything and the camera keep focusing on the origin. Am I doing something wrong or the problem is still existing?
I have installed the last versione from source.
It's set_cam_target() and set_cam_pos(), see here.
Working well for me installed from source.
