Rushan, please could you specify what you specifically mean under the notion of 'geometric modelling', e.g. 2D, 3D; or geometry in N-dimentional spaces?
"The shapes studied in geometric modeling are mostly two- or three-dimensional, although many of its tools and principles can be applied to sets of any finite dimension."
Geometrical modeling from insider’s perspective have very long history. People explain their own geometric ideas and knowledge to perform their everyday activitie. For eg stone carvers and wood carvers create different geometric objects in their work implicitly but those people performed since long in craft model approaches.
