Canoma was a 3D-modelling application for Windows and Macintosh. Released by MetaCreations Corp. in 1999,[2] this application allowed users to create 3D models based on one or more photographs taken from various angles. This process is known as photogrammetry. The user "pinned" the corners of wireframe primitives over real world shapes such as buildings, boxes, cylinders and other geometric shapes (it could not really handle organic shapes), the application then dynamically extrapolated the perspective, angles and shapes and produced a 3D realization, applying the textures from the
photograph(s) onto the models.
