CloudCompare forum

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...

Hello, Denial I met a very weird problem which did not occur before. I tried to change the color of points in cloudpoints and hoped that their colors could be changed immediately. However, the reality is that the colors would not be changed immediately. In fact, I should change the option of "A...

Hi daniel, My problem is that I want to add point picking function in my plugin and it seems I should inherit ccPointPickingGenericInterface and implement some virtual functions. However, when I inherited ccPointPickingGenericInterface and compiled my plugin, the following errors occurred: error LNK...

Hi Daniel, I met a very thorny problem when I used cloudcompare. When I choose or cut cloud points, it seems that cloud compare would choose all points that is in the polygon drawn by users. However, in most cases, I just want to choose those points which is not covered. In other words, I want choos...

You have to use the point picking mechanism. The best way now is to use the 'PickingHub' class (see how it is used in various places in the code: camera parameters dialog, plane edit dialog, etc.). EDIT: to see how it's integrated in a plugin more specifically, see the QCompass plugin Thanks for yo...

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.

Hi Deniel, I met a very strange problem.

However, if I comment this function and try to compile it again. CC would ad...

Hi Denial! I need your help. Here is my problem, I use CC to read a data and then CC generate a ccGenericPointCloud. now I want to change this ccGenericPointCloud to a ccPointCloud with some scalars and let CC change points' color in this ccPointCloud according to the certain number in the first sca...

Thanks for your response. I have thought this problem for nearly 5 hours, then I know the reason and wondering why I am so stuipd... the answear is there are 2 lays in the picture, the blue one is above the green one, so after blue layer dispears, we can see those green points. But at the begining I...

Hi denial, I met a very strange problem. What I want to do is to change the visibility of each cloudpoints according its classification. But if I try to change the visibility of cloudpoint whose classification is 1(I think 1 represent Vegetation), then those cloudpoints whose classification is 2(Gro...
