Deformación de modelos elastoplásticos mediante interacción háptica

Zusammenfassung

Solid deformation has always been a field of great interest within the Computer Graphics community. Many works have aimed to create a natural, reliable interaction with elastic or elastoplastic solids. However, there are also many problems that appear when playing in this scenario. When designing a simulation, realism is always confronted with performance, and there are indeed many aspects of solid deformation that require intensive use of the computation resources. It is therefore necessary to find a compromise between these two desired properties. This work targets creating a new simulation environment for deformable materials, trying to maximize realism while maintaining interactive response times. Additionally a method of tactile interaction method is proposed. Whereas other works have focused on creating a fast response using the intuitive behaviour of clay, continuum mechanics are used in this work to inspire and support the force rendering algorithm and the visualization of the modeled deformation. This PhD thesis details the motivation, formalization, design process and evaluation of the proposed system will be detailed. Thus these pages explain how following the formal behaviour of an elasto-plastic solid, a method offering a natural, efficient, and plausible interaction with deformable materials, has been built.
