PRE- AND POSTPROCESSOR LOGOS PREPOST. SPECIAL FEATURES OF THE ELEMENT PICKING MECHANISM

D. V. Antoshin, A. V. Gordeev
VANT. Ser.: Mat. Mod. Fiz. Proc 2014. Вып.4. С. 73-78.

The paper describes the grid element picking mechanism implemented in the LOGOS-Prepost pre- and postprocessor. Two element picking models are presented: the old one using the VTK filters, and the new one based on the mechanism of operations. The drawbacks of the old model are listed. The features of the new model are described, which provide high gain in speed and enhanced functionality. The model is compared with foreign counterparts with respect to the grid element picking rate.

Keywords: pre- and postprocessor, picking, VTK, mechanism of operations, visualization.
