In recent years multithreaded processing has become a important programming aspect. Computers with a multi-core processor are now widely available, enabling the creation of more efficient applications. Many libraries support multithreaded solutions, but performance information is often lacking. The use of appropriate data structures and algorithms significantly speeds up the process of creation and development of applications. Article describes selected elements of the Qt and STL library and compares their performance in concurrent programming. The time needed to perform individual operations was analysed.

Abstract Feature-based design has evolved as a fundamental paradigm for present-day CAD systems. Voxel-based modeling has many advantages over traditional representation schemes but lacks structural information which is lost in voxelization of the objects. In this paper, we propose to augment voxel models with features by a) storing the sequence of modeling operations along with voxel models and b) by defining feature operators. We have implemented these ideas in our prototype system Sirpi as regularised Minkowski operators using simple data structures and algorithms.
