How to replace points in PCLVisualizer to shape?

Hello All,

I'm drawing the point cloud data using this library, http://docs.pointclouds.org/1.8.1/cl...isualizer.html

Now I can see point cloud data (In terms of points) on the widgets, but I want to replace all points with another shape (like cross and circle).

I know we can add shapes (line, sphere, arrow, polygon) to widgets, but I don't want to add, I just want to replace all point to a particular shape.

So if anyone has done this or has an idea please suggest me.

Thanks in advance!

What does this question have to do with Qt? PCL uses VTK as a visualization tool, and VTK is OpenGL-based. You should be asking this question on a PCL forum.

I have asked them also, but I didn't get a reply so far.
I was developing this in Qt, and I have done it completely. Now I just want to distinguish the data from other PCD if I have connected multiple PCD inputs.
And I think if someone has done the same so far, then it might help me.
