Abstract

Industrial designers are always in search of new tools that can create a product more technically and artistically. Conventional Computer-aided Design (CCAD) supports only creation, modification, analysis, and optimization of design. Worthwhile CCAD is not much supportive in the artistic activities associated with the conceptual design phase of the product design. For conceptual design, the designer requires freedom to modify the product specifications frequently to study the product behavior regarding attributes like product shape, strength, deformation, surface roughness, ergonomics, and many other aspects. The present research is made to investigate the deformation of the product using a virtual model of Plasticine material. The virtual product model is generated from point cloud data. The deformable Volumetric Self-organizing Feature Map (VSOFM) is used as an adaptive geometric modeling tool. VSOFM provides a framework for generating objects that dynamically change shape during the design process. To assign the material properties, the point cloud data meshes with B-spline incorporated with spring and dampers. The collision is detected between the tool and the B-spline based teardrop model. Deforming force is applied to the Plasticine model to check the mode of deformation. It is concluded that B-spline based Plasticine model exhibits material properties more efficiently and accurately during collision detection and deformation.
