Get Rotation Matrix from 2 Orthogonal Planes

07 Jun 2012

Computes a 3x3 rotation matrix from two orthogonal planes in a 3D point cloud.

File Information
Description	Shows a 3D point cloud and lets the user select a plane by clicking on two points. The selected plane is highlighted. The math is pretty simple: A surface normal is computed for each plane using eigenvectors, later the y axis is set to be 0, any rotation is subtracted from it to obtain orthogonals surface normals. The cross product ot them is computed to obtan the z axis normal and conform the 3x3 rotation matrix.
