Greater control in segmentation tool

[andrewmcunliffe]

Hi,

Would it maybe be possible to increase control over the segmentation tools; for example, by segmenting a sphere with a specifiable radii around a user-selected point?

(My application has many overlapping scans around the same site, so I'm trying to only incorporate data from a few of the closest and most accurate scans in the final registered model).

Cheers, Andy

It may be a bit 'heavy' to add such an option to the segmentation tool.

But you can do this "manually":

• use the point "Point list picking' tool to select the center point and create a new cloud with it
• compute the distances between the original cloud (as 'compared') and the new single point cloud (as 'reference') - use a very low octree level as the computation might be very long.
• eventually segment the original cloud based on its distances to the single point (with "Edit > Scalar Fields > Filter by value")

Thanks, I'll try that solution
