A spatial partitioning heuristic for automatic adjustment of the 3D navigation speed in multiscale virtual environments
With technological evolution, 3D virtual environments continuously increase in complexity; such is the case with multiscale environments, i.e., environments that contain groups of objects with extremely diverging levels of scale. Such scale variation makes it difficult to interactively navigate in this kind of environment since it demands repetitive and unintuitive adjustments in either velocity or scale, according to the objects that are close to the observer, in order to ensure a comfortable and stable navigation. Recent efforts have been developed working with heavy GPU based solutions that are not feasible depending on the complexity of the scene. We present a spatial partitioning heuristic for automatic adjustment of the 3D navigation speed in a multiscale virtual environment minimizing the workload and transferring it to the CPU, allowing the GPU to focus on rendering. With the scene topological information obtained in a preprocessing phase, we are able to obtain, in real-time,...
