Storing PointCloud2 type msgs in an octomap

Hello everyone,

I am receiving a pointCloud2 type messages by subscribing to a topic, in my code. Now I need to build an octomap from this. I am currently using Groovy and Octomap libraries for ROS Groovy.

I have gone through the documentation of octomap, but couldn't retrieve much from that. The function octomap::insertPointCloud() is somewhat close to my requirement.

Is there a way to create an octomap using this API for the callback being received ? And can I eventually write an octomap-file to the disk using some function ?

I have gone through few threads like this also but not able to get a concrete idea. http://

I'd be grateful if someone can point me to an example code for the same or the order we need to follow to achieve this ?
