I know that you can visualize a .pcd with the intensities by using the pcl
visualizer library, and that you can specify the color of the point cloud in
terminal command 'pcl_viewer' with the "-fc r g b" command, however, it
would be very useful for me to quickly visualize point clouds with intensity
while using the terminal 'pcl_viewer' since it makes it a lot easier for
overlapping various point clouds. Thank you in advance!
