This is an easy operation. Is your point cloud organized to begin with? If so, you can just assemble an image of cloud.width x cloud.height and set your pixels in the image according to whatever free criterion you have in mind. If the dataset is not organized, you might need to do some projection first. PS. Please use pcl-users@ for PCL related questions. Thank you. Cheers, Radu. -- http://pointclouds.org
