3D Organic Modeling Using Hybrid Techniques with Polygons

This work presents a methodology of 3D modeling suitable for the design and manufacture of components with complex forms of organic inspiration. It is applied to a real case of development of a sculptural element related to the corporate image of a company. In the introduction, the boundary conditions of the project and the product to be modeled with the starting specifications are presented. Next, the stages followed for the execution of the project that give justification to the methodology developed are described. The document shows the general flow of activities presenting in each one the particularities and resolved contingencies. The tangible results of the project that includes the variations of the model generated for 3D animation equipped with articulated bones are also exposed. It has been experimentally verified that the proposed modeling methodology allows the integration of components designed by CAD, generates topologies coherent with innovative criteria that they facilitate production through additive manufacturing with related surfaces free of errors. It is, therefore, a hybrid method based on the manipulation of mesh polygons with accessible tools that is suitable for the design and manufacture of bio-inspired products, paleontological reconstructions, prostheses or bio-engineering components. The UV coordinate maps and the designed textures make it possible for the same geometry or simplified versions of the manufactured model to be modified by means of 3D animation techniques with skeletons, to be used in virtual representations and in augmented reality environments, increasingly demanded in the field of Graphic Engineering.
