Switch between representations on Point() object

[jkissi]

Hi Marco, hope you are well!

I would like to be able switch between views of my pointcloud coloured for my classification or curvature (with the curvature option having an accompanying cmap.scalarbar()).

I also want to be able to turn the normals of the points on or off. You gave me a previous answer using a button to call plt.remove(pcl).add(new_pcl) but I am confirming because if I use this method, I would have to have a different point cloud for each of the different combinations:

vpts0 # classification with normals 
vpts1 # classification without normals 
vpts2 # curvature with normals etc.... 

Is this the most efficient way of doing this or can I use the pointdata.select() method to switch between different point representations on the same cloud?

If I use the pointdata.select() method, is there a way to remove the scalarbar() from the Points object dynamically and render, or is it the case that once you add this to an object, you're stuck with it? (so you have create a different object if you don't want it to show)

Thanks, hope you had a good weekend!

Hi, you can add and remove any item(s) with
plotter.remove(some_list).add(some_other_list)
(probably you want to do this in a callback function)

Another option is to switch on and off an object visibility with:
myobject.on()
myobject.off()

For the scalarbar you may need to extract it from the associated mesh and handle it like any other vedo object:
myscalarbar = mymesh.scalarbar

Give it a try!

PS: sorry while reading back I think I missed some of the points you raised.. You can use select() you just need to add as many arrays to the point cloud as you wish then you can select the relevant one and render() the scene (you do this in a callback or button).
Hope this helps,
Marco
