SpiderPig Posted December 21, 2018 Posted December 21, 2018 Does any one know how to get a normal that will tell the general direction all the vertices of an object lay in? Like an average position, but as a normal... any one got any ideas? Quote
Josh Posted December 21, 2018 Posted December 21, 2018 Take a 360 degree (in 3D space) sample of all vertex deviances from the average 2D position, transformed to that vector / angle, and try to find the angle with the smallest deviance? 1 Quote My job is to make tools you love, with the features you want, and performance you can't live without.
Solution Ma-Shell Posted December 22, 2018 Solution Posted December 22, 2018 The problem you are trying to solve is called "Principal Component Analysis (PCA)". The process involves quite a lot of math, computing Eigenvalues, etc. I'm not entirely familiar with how it works either but just throwing this term at you, so you can use the name for further research 1 Quote
Josh Posted December 22, 2018 Posted December 22, 2018 Wow, we got a smart person here. 1 1 Quote My job is to make tools you love, with the features you want, and performance you can't live without.
