Load a label list

Post by westergu »

Hi,
Is it possible to load and visualize 3d points with labels in CC? I have a list of 3D points that all have uniqe names (control points). I would really like to visualize these points togheter with their names, like when you have a "point pick list".
In the Point picking tool you can save the picked points in the format "label name,x,y,z", but I can not find a way then how to open such kind of formats. I thought I could trick the program that my control points is a "Picked point list" with labels.

Is there a way how to do this?

Best regards,
Gustav Westerlund

We'll have to work on this, but it should be feasible.

Hi, i have the exact same problem. I need to visually see labels on a set of control points, in order to perform an align point pairs operation.

It looks like you found a way to address the problem, which is great! But the link you provided no longer works. Could you please reactivate it?

Just to say a big thanks for providing such a magnificent software. I recently made a sizeable cash contribution on account of using it so much. You sir are a Saint.

That's great, but which tool is used to perform this function?

Thanks

You actually have to load the points (with labels) as a text/ASCII file.

On each line you will have the coordinates of each point (X Y Z) as well as other fields (colors, normals, etc.) and the label. Then you can choose the corresponding column to be loaded as "labels". That's all.

First off, many thanks for this software! I will be sending over some data sets that my team is working with for the CC dev team to play with.

I also have points that have a unique identifier and would love to be able to have this unique identifier appear when I pick points. I have tried to load in points with labels with the method described above, but CC freezes with large point clouds (I'm importing a file with ~2mil points). I can load smaller point clouds, but it is wayyy slower than normal. Even with a beefy desktop with 32gb ram and a gtx 960 GPU.

Is there a way to assign labels but not "enable" the labels automatically? Like a toggle to show labels of selected points or individually or just have them included when you pick points to a list?

Thanks a ton!
