Mehtod for Estimating Surface Normals?

Post by Xifa »

Hi, I want to know more about how the Normals\Compute function works in CloudCompare. Is there any paper that explains how the method works, and maybe some examples to help understand it?

I don't believe there's any paper (or maybe my PhD manuscript, but it's in French sadly...).

You can refer to https://www.cloudcompare.org/doc/wiki/i ... %5CCompute

Or https://pointclouds.org/documentation/t ... ation.html which shares same common principles (especially the PCA part when the 'plane' mode is chosen in CloudCompare)

Hi Daniel,

I want to ask about the method used for 2D triangulation in CloudCompare. I couldn't find a method specifically named "2D triangulation." In my work, I’ve explained the plane model using the PCL method and the quadric model with the height function(Normal form of projective quadrics,i think this is the part that used in cloudcompare). However, I need to provide a more detailed explanation of the differences between these methods, including their pros and cons.

Could you provide more information?
