Abstract
Systems and methods are disclosed for removing details from three dimensional (3D) objects, such as cavities and holes. Complexity reduction via cavity removal reduces storage, transfer, and rendering costs without adversely impacting quality and is implemented in an automated manner. In some examples, distance fields internal and external to the 3D object are removed in a layered manner, and new object surfaces are added wherever openings are narrower than the cavity's internal dimensions, to seal off the cavities. Holes and cavities, which are obscured in many viewing angles, are thus filled in (e.g., removed), thereby reducing the burden of storing and processing hidden interior surfaces. Various approaches, leveraging distance fields, may be combined for improved benefit.
