Web31 jul. 2009 · You have a simple triangle, so your problem is solveable with the law of cosines. No need for any polar coordinate tranformation or somesuch. Say the distances are P1-P2 = A, P2-P3 = B and P3-P1 = C: Angle = arccos ( (B^2-A^2-C^2) / 2AC ) All you need to do is calculate the length of the distances A, B and C. Web13 okt. 2013 · A surface normal for a triangle can be calculated by taking the vector cross product of two edges of that triangle. The order of the vertices used in the calculation …
