create a label from a position

[fblue]

Hello,

Can I create a cc2DLabel which associates a point which doesn't exist in a point cloud?

The method addPoint() in cc2DLabel needs the index of a point in the point cloud to give a label to this point. But if in a known position(x,y,z) where the cloud has no point, can I still create a label? Or I have to create at first a point with this position and add it to the point cloud?

Thanks

Nope. It can only point to an existing point (and it automatically adaptas to this points position, in case the cloud is transformed, etc.).
