Many tasks typical for High Energy Physics such as simulation,event display,maintenance of the geometry database of an experiment,require input of geometrical data.To simplify the process of preparation of such kinds of data an interactive graphica tool GBuilder is being develogped.Definition of the geometry model in GBuilder is based on the Constructive Solid Geometry approach where objects are defined using boolean operations on basic shapes.To provids parameterization of the model arithmetic expressions may be used in place of numbers,A wide list of predefined materials is also available.Different drivers allow to output the geometry model in a form suitable for specific simulation of visual analysis tools. 展开更多
