Bump mapping techniques are widely used to simulate structural details of tridimensional surfaces in order to improve visual quality and compensate for the low geometric detailing generally applied to models sent to the GPU due to performance issues. Recent advances in the rendering pipeline enabled the massive generation of vertex data in the graphics hardware by means of the tessellation feature, providing developers with a powerful tool to control the meshes’ level of details. The present work proposes a technique for geometric detailing of models using hardware tessellation, both based on pre-computed depth maps and on displacement data generated entirely on the GPU through procedural textures techniques. Performance and visual quality analysis demonstrates the advantages of the proposed method in relation to an image-based technique commonly used in videogames for enhancing the visual quality of the environments.
