HelloIs there a way to retrieve an array of only visible points of selected object in scene view?
Just like e.g. standard selection tool is able to select only visible polys/points, I am looking for a way to do the same thing from code but for the entire object.

Hi and Welcome to the Plugin Cafe forums!
The class ViewportSelect gives the information needed to obtain an object's visible points.
Call ViewportSelect::Init() with op set to the selected object and onlyvisible set to true.
Then use ViewportSelect::GetPixelInfoPoint() with each pixel coordinate of the view and check if the object for the pixel (ViewportPixel::op) is the active object. If true retrieve the point index (ViewportPixel::i) and process the next pixel.

If point is smaller than a pixel the point is not selected (that also happend with c4d selection tool) is there a workaround?

Thank you Yannick, I was hoping there is a nice class that offers a method to achieve this. It's exactly what I needed to make things work! ****

This is a limitation of ViewportSelect class.

Thanks for the answer. It's very sad. I hope it will be "fixed".
