Hardware-based techniques applicable for ray tracing for efficiently representing and processing an arbitrary bounding volume
Granted: May 30, 2023
Patent Number:
11663770
A bounding volume is used to approximate the space an object occupies. If a more precise understanding beyond an approximation is required, the object itself is then inspected to determine what space it occupies. Often, a simple volume (such as an axis-aligned box) is used as bounding volume to approximate the space occupied by an object. But objects can be arbitrary, complicated shapes. So a simple volume often does not fit the object very well. That causes a lot of space that is not…
