Description

Many, many beginning users thinks their code is not working just because of the viewer initial point of view.

The last topics about this "bug": http://www.pcl-users.org/ http://www.pcl-users.org/

I think this concerns both the PCLVisualizer (when displaying axis) and the CloudViewer.

Research direction
Investigate the PCLVisualizer and CloudViewer classes in the PCL source code to find where the default camera position is set. Adjust the initial view to show the point cloud more clearly, possibly by setting a better default viewpoint. Consider looking at the linked forum discussions for user feedback on what initial view would be better.
