Visualização de malhas com adaptação de resolução e textura dependente do observador

Abstract

This work has the goal of explore the triangulated mesh visualization problem in order that geometry and texture information could be computed adaptively according to the view position. As only the essential information from the mesh is going to persist, the main applications involved are linked with real-time mesh visualization which concerns a large number of scientific areas. To adapt the mesh geometry, its resolution is being locally changed through the insertion/removal of vertices, edges and faces, view-dependent considering the number of polygons to preserve smooth forms near to the original mesh. In the texture adaptation, the texture map association of the mesh is being adapted to the resolution changes minimizing or eliminating the texture distortion resulting from the collapse of vertices, edges and faces
