Re: Redraw function did not work

Thank you Daniel(I hope this time I call your name correctly :D), this function works. But I still do not understand what the function of "Redraw()" is. And few weeks ago, the colors of points could be changed immediately when I modified the scalar field even I did not add this function. W...

Could you tell me how to get the closest point in cloud when I click my mouse?

Hi, Denial

I want to implement a simple function in my plugin.

When I click my mouse, I want to get the index of the closest point in the cloud. I think there must be some functions in the cloudcompare that I could use, please tell me.
