ok real science talk is how do i find positions, angle, length of lines of
AC , BC, CF, CD as they need to form enough space to create 3d space and then BC to NO and how BC shows it is "above" NO in distance to the eye and its "curvyness" and then FS QR

what are the mathemathics to this or am i wrong to ask this since math is only dealing with values and not about correct forms?
