CloudCompare - Unroll Function

Post by Lukas Loula » Tue Jul 15, 2014 6:01 am

Hi everyone,

I would like to ask you if someone have successfully used an unroll function for cone in CloudCompare software.

My expectation was to get as a result of a similar shape to the one from this image:

But the result I got looks significantly different - rectangular:

I have tried different parameters in CloudCompare but all my tests end up as rectangles.

What have I missed? Or would you have suggestions for any alternative to the CloudCompare?

Thanks a lot!

Lukas

Hi,

Indeed the "Unroll cone" function is not a conical projection. It actually unfolds a conical shape as if it was a rectangular paper sheet.

To achieve this in CC you could use the qSRA plugin (http://www.cloudcompare.org/doc/wiki/in ... =PluginSRA) but only to get the distance map relatively to a theoretical shape.
