invalidateViewport();
invalidateVisualization();
deprecate3DLayer();

When I was sorting out the code, after seeing a lot of setcameraposs, I entered these three codes, and I couldn't understand what these three codes do. I have seen your comment, but I don't understand what it does.

Thank you for your guidance, I am going to improve my plug-in function, I believe I will come to ask you again in the near future

First of all thank you for your guidance. I wrote the functions I needed in the plug-in. I used the setCamerePos and setCustomView functions, and set different coordinates in a loop to achieve the effect of dynamically displaying the point cloud. It’s a pity that the display interface would have bee...

Sorry, I did not find the code that only refreshes the display interface, can you tell me, thank you!

Terrible!
refreshAll();
updateUI();

These two lines of functions seem to refresh the entire interface. This is not what I want. What I want is to refresh the display interface. It seems that I need to find a way again.

setCustomView（）

regret！
For this function, I need to use the negative number of the coordinates, but when the coordinates are set to a certain value, it's the opposite again.

refreshAll();
updateUI();

Excited!
By accident, I found these two lines of code, and my camera started to change position, not just displaying the last coordinate. Can you tell me what these two lines mean?

I'm so excited I set the coordinates! But I set multiple coordinates and cc only shows the location of the last coordinate. For example: setCameraPos(3,5,0); sleep(1); setCameraPos(5,1,0); sleep(1); setCameraPos(10,15,5); sleep(1); setCameraPos(3,5,4); So I set up the coordinates of four positions, ...

Yes, I need a fixed perspective.
I needed to set different coordinates for the camera to see the point cloud.
Thank you for your reply.
