Second picking pass for instanced renderables, point clouds

Why second pass instead of assigning an id per instance during the first pass?

That could work if we think up a way to assign non-colliding IDs inexpensively.

Had a chat and going to push this until after GA.

This ticket is about selecting individual points in point clouds.

Also applies to individual cubes/spheres in cube_list/sphere_list markers, right?

If that is true and we optimize how we render those then I think we need a solution here. Its one thing to wait on selecting individual points in a point cloud but not being able to select the scene objects seems like a loss of functionality that is more than we had in mind when deciding to punt on this.

Selecting cubes/sphere in lists works fine. You are shown the full marker message that contains the specific selection though, instead of drilling down to the array index for the specific cube or sphere you clicked on.

Re-surfacing this as higher priority. This is a feature of the existing 3d panel and is now a customer request. At minimum having the ability to click a point cloud point and see the x/y/z. We can re-target the issue for that specific feature if thats easier than the larger scope this issue might describe.
