摘要: Various embodiments for hit testing of visual objects are described herein. Data of visual objects is generated in a two-dimensional clip space. The data of visual objects includes two-dimensional projections of the visual objects. Cursor coordinates are transformed into the clip space and bounding box calculations are performed using the transformed cursor coordinates and the generated data. Hit testing is performed when there is a hit on a bounding box of at least one of the visual objects in the clip space. The hit testing is performed in a three-dimensional space. A result is then presented on a user interface based on the hit testing.
