Maximum Mipmaps for Fast, Accurate, and Scalable Dynamic Height Field Rendering
This paper presents a GPU-based, fast, and accurate dynamic height field rendering technique that scales well to large scale height fields. Current real-time rendering algorithms for dynamic height fields employ approximate ray-height field intersection methods, whereas accurate algorithms require pre-computation in the order of seconds to minutes and are thus not suitable for dynamic height field rendering. We alleviate this problem by using maximum mipmaps, a hierarchical data structure supporting accurate and efficient rendering while simultaneously lowering the pre-computation costs to negligible levels. Furthermore, maximum mipmaps allow for view-dependent level-of-detail rendering. In combination with hierarchical ray-stepping this results in an efficient intersection algorithm for large scale height fields.

Abstract
After decades of research on digital representations of
material and object appearance, computer graphics has more
recently turned to the problem of creating physical
artifacts with controllable appearance characteristics.
While this work has mostly progressed in two parallel
streams – display technologies as well as novel fabrication
processes – we believe there is a large overlap and the
potential for synergies between these two approaches. In
this report, we summarize research efforts from the worlds
of fabrication display, and categorize the different
approaches into a common taxonomy. We believe that this
report can serve as a basis for systematic exploration of
the design space in future research.
