Can cc display the coordinates of each point? Can cc display video?

[xiaolu]

Hi there,

I would like to know
can cc display the coordinates of each point?
can cc display video?

Thanks for the help!

You can create a label on any point to show its coordinates (with SHIFT + LEFT CLICK on the point, or via the 'Point picking tool').

And you can create videos (with the Animation plugin: https://www.cloudcompare.org/doc/wiki/i ... n_(plugin)

(but it cannot 'display' videos).

thanks for your reply，
Can cc “visualize” the coordinate axis? Instead of displaying numbers? I want to see more intuitively.
Thanks.

Sorry, I'm not sure to understand?

I want to display the coordinates for each point, just like the picture.

Are you interested by the number attached to each point, or by the trihedron (the 3 vectors)?

Well, you can't display any of them in CloudCompare. But mind that to display a trihedron, you need more that a point, but also at least 2 vectors (and more probably 3 vectors, or a 3x3 matrix).

So actually you can do both of these (sort of).

for the point index label, use the point picking tool, select a single point and create a 2d label, then select the label in the DB tree and turn off "Show 2D label" and turn on "Show legend(s)"

for the coordinate display you can use the "CoordinateSystem" primitive with the translation vector set the same as the point coordinates. (you will need to decide orientation with some more information like Daniel said)

Here is an example of following those instructions, on one of the CoordinateSystems I turned off plane display

But this is a fair amount of effort per point so it would not be optimal to do this by hand for a large qty of points.

Thank you all for your advice,
I did this with pcl.
