Pointcloud type casting question

Post by PhilipK »

Hello,

I want to adapt the distance-function in

Code: Select all

DgmOctree::findTheNearestNeighborStartingFromCell
to include different features (scalar fields). For this, I have to get access to all available scalar fields in the cloud but m_theAssociatedCloud is of type GenericIndexedCloudPersist. Is it save to cast m_theAssociatedCloud into a ccPointCloud? Or is there another way of getting access to the cloud's scalar fields?

I thank you in advance for your answers!

Best regads,
Philip

Hum, sadly, CCCoreLib cannot handle multiple scalar fields per cloud. The best way to do that would be to copy the code in a different part of CloudCompare (e.g. the CloudCompare project itself, or a plugin). Then, update it there, and replace the generic clouds by ccPointClouds, etc.

Hi Daniel!

Okay I understand - than I will move / copy the necessary code parts into a plugin!
Thanks for your answer!

Best regards,
Philip
