pareto based optimization of multi-resolution geometry for real time rendering
This paper proposes a view-dependent quality-cost trade-off decision-taking framework for time-critical multi-resolution rendering. The paper extends existing surface to surface error metrics to a view-dependent accuracy heuristic, used in an off-line process for establishing a representative set of elementary accuracy-cost trade-off curves. These so-called Pareto plots are combined at run-time according to the object meshes visibility and importance (e.g. object distance) for proper global view-dependent quality-cost trade-off decision taking at minimum run-time cost. A more realistic viewpoint-dependent quality metric is introduced without sacrificing too much of the simplicity of earlier proposals.
