Hello, I need calculate the angles projections of a segment in space by planes. For example the segment foot and shank, where the foot is defined by P1 and P2 and shank is defined by P2 and P3 in the space, I need obtain the angle between the segments, but I need too of your projections, anyone help me? Thanks for your attention. Best wishes.
% Example:
P1(68,7910000000000 -79,5270000000000 18,0130000000000)P2(40,3690000000000 57,5610000000000 -86,0590000000000)P3(-94,3560000000000 109,322000000000 78,3600000000000)
If you see the image, I need the angle projection in xy, xz and yz plane. Do you understand my question?
