elkyu Posted June 30, 2015 Share Posted June 30, 2015 Hi, Yes, me again ... So, I still have my plane with some face (triangle) compose by 3 vertex. I can get the face ID, get the 3 vertex which compose a face, get the normal of each vertex but now, I would like to find how to get the normal of a face (not the all plane, just one face) .. I try with the function getNormal() (pickingInformation) but each time that return x=0 y=1 z=0, but some face are inverted and the function return the same result I don't know why Quote Link to comment Share on other sites More sharing options...
