Complete approach
•Load in an image
•Click on lines parallel to X axis
–repeat for Y, Z axes
•Compute vanishing points
•Specify 3D and 2D positions of 4 points on reference plane
•Compute homography H
•Specify a reference height
•Compute 3D positions of several points
•Create a 3D model from these points
•Extract texture maps
•Output a VRML model
