Abstract
The purpose of this project is to create a virtual environment for engineering design optimization. NURBS-based free form deformation techniques have been combined with stress sensitivities and implemented in a virtual environment to allow a designer to change the shape of a design and immediately view the stress distribution changes. Designer-weighted optimization is implemented to guide the designer to investigate designs in the vicinity change the shape of the design using natural three-dimensional movements. Stereo viewing further enhances the three-dimensional appearance and interpretation of computer-generated geometry. This intuitive interface allow the designer to concentrate on evaluation of the analysis results and provides a natural interface to interacting with computer images and databases.
