This paper presents a very simple and effective procedure to combine data from two cameras, and different positions, to produce clouds of points in regular meshes. The main idea starts by setting two independent coordinates for a node from a regular mesh. The third coordinate is found by scanning the dependent coordinate across the measurement volume until the phase values of the fringe patterns, acquired by the cameras, reach the same common value. This approach naturally produces structured clouds of points independently of the number of cameras used. To measure large or complex volumes, some marks are distributed by the geometry. Two geometry parts with common marks are measured in different positions and stitched. Many parts can be measured and stitched, until the complete measurement of geometry. The final result is a regular mesh of the cloud of points.
