CloudCompare forum

Hi Daniel, i need your help again...

I need to understand what does "normals" mean. "Normals" are lines? I am doing a surface from a cloud point with "poisson" but i need to know what mean "normals".

Thanks!!!

Here is what a 'normal' exactly is: http://mathworld.wolfram.com/NormalVector.html

You need them to know on what's 'inside' and what's 'outisde'.

And you can compute normals in CC with http://www.cloudcompare.org/doc/wiki/in ... %5CCompute. But depending on the cloud that might be tricky...
