Name

common_line_in3D - locate a common line between projections. The latter are denoted by the rotations RA and RB, where RA is (phiA,thetaA,psiA) etc.

• Formula is (RB^T zhat) cross (RA^T zhat) Returns phi, theta of the common line in degrees.

Usage

• phiC, thetaC = common_line_in3D(phiA,thetaA,phiB,thetaB)

Input

phiA, thetaA

first two Eulers of the rotation describing the first projection.

phiB, thetaB

first two Eulers of the rotation describing the second projection.

---

Output

• phiC, thetaC = the spherical coordinates of the common line
