Nowadays computer graphics allows to render realistic images of the 3D world. However, before such images can be generated, graphics models of the world must be available. Traditionally, these models where obtained using 3D modelling packages. This is a very time consuming process and the achievable level of detail and realism is limited. Therefore, more and more 3D models are obtained by sampling the world. Different approaches are available for this. Best known are probably laser range

Another approach consists of using images of the scene or objects one wishes to reconstruct. A simple example consists of taking a picture to use it as a texture map for a 3D model. However, not only the appearance, but also the 3D shape can be extracted from images. This will be the main subject of this paper.
