Abstract
Systems and methods for providing smooth level of detail transitions for geometric objects, such as geometric terrain tiles, are provided. In one embodiment, a parent geometric tile associated with a first level of detail can be partitioned into sub-tiles. The sub-tiles can be blended independently with child geometric tiles associated with a second level of detail. The blends can be adjusted as a function of camera distance over a transition range to provide a smooth level of detail transition. Various enhancements and modifications can be made to the level of detail transition, such as implementing a bias in the level of detail calculation, implementing an unpop algorithm over only a subset of the transition range, implementing a time based fade during a camera stop, and other enhancements.
