How do I select all the points for rendering at once

[Chenguoz]

Great Work! I tried to render the point cloud file of the example and found that I can only select one point at a time, is there a way to select all the points in the point cloud for rendering？Thank you!

I somehow missed this issue until now... It should by default be rendering all points; isn't the example working? Thanks very much if I can improve it.
