Abstract
Methods and systems for fractional level of detail assignment are described herein. A method embodiment for fractional level of detail (LOD) assignment includes obtaining a set of features and image data at a range of LOD values, assigning one or more fractional LOD values to the obtained features and providing the features and the image data at the fractional LOD values. The embodiment also includes hashing an identifier associated with each feature and computing a hash cutoff value by mapping the range of LOD levels onto a range of integers. A system embodiment includes a LOD assigner to assign fractional LOD values to features in image data and to provide the features and the image data at the fractional LOD values. The system embodiment further includes a retrieval engine to return features with a range of LOD values that include the fractional LOD values to the LOD assigner.
