Change number colour in 3D plot - map.pick method

[npuletti]

Dear all,
I'm trying TreeMap function with map.pick method.
somenthing like treeMap(tls, map.pick(min_h = 1, max_h = 5)) When I right-click over a trunk, a number in black appears. The background is in black too and such configuration is not suitable to check the status of trunk selection.
Can I set a different colour for tree-id numbers (e.g. Yellow)?

Thanks

Thanks for the comment!

The black number that appears after the click is the row number of the closest point, so the number itself is not useful whatsoever. I just wrapped rgl::identify3d inside map.pick, and unfortunately I can't change the label styling inside of it. I'll consider refactoring that function to improve interactivity though.

Cheers

We have also used this function after the map.hough function to pick up trees missed in messy point clouds. Rather than change the color of the ID numbers, it would be easier to change the background color of the rgl instance. Especially since the points are variously colored already. I tried adding rgl::bg3d('gray50') but since the rgl instance is opened in the function and then the picking, it changes the background after the picking is done. If this command was wrapped in the map.pick function after the rgl was called, it might work.

fair enough. I'll add a parameter to select the background color then. Thanks @spokswinski
