                         grammars for representing and rendering massive 3D CAD models in 
                         real time. Procedural modeling is an appealing approach to quickly 
                         generate massive scenes while maintaining compact representation. 
                         Until now, procedural modeling has not been explored in the domain 
                         of large industrial projects. Traditional procedural modeling 
                         techniques generate parameterized random scenes. In order to 
                         achieve an accurate representation for pre-existing 3D CAD scenes, 
                         we propose a specialized Shape grammar. We used common geometric 
                         primitives found in real 3D CAD models to create a compact model 
                         representation. In addition, we describe an efficient rendering 
                         algorithm to draw CAD Shape Grammars in real time. We evaluated 
                         both performance and memory consumption of our proposed technique 
                         using real-world CAD models. Results indicate not only high 
                         rendering performance, but a significant reduction in the memory 
                         required to represent massive 3D CAD models.",
