The aim of this document is to explore the way that Blender 2.32 stores the information for modeling static scenes. First, the conceptual model the system uses to store geometric objects is explained, guiding the user to inspect it using the OOPS Schematic view. The data structures Blender uses for generic objects, geometric elements, materials and different kind of links between these entities are reviewed. Special emphasis is made for the case of meshes, and the main features of the mesh editor are enumerated. Finally, a collection of exercices for the user is suggested, with the aim that he/she enforces these concepts.
