  • Light transport consistent scene simplification within graphics display system
    Patent number: 9171394
    Abstract: Method including casting a first plurality of rays towards an original 3-D scene comprising objects with object surfaces. Method also includes constructing a simplified representation of the original 3-D scene and adjusting the simplified representation to be consistent with the original 3-D scene. Simplified representation is adjusted by using known rays and object surface intersections obtained from the casting, to produce an adjusted simplified representation.
    Type: Grant

    Date of Patent: October 27, 2015

  • Surface classification for point-based rendering within graphics display system
    Patent number: 9159158
    Abstract: A method including casting a ray from a point toward a point-based three dimensional scene. The scene includes memory resident objects with object surfaces and a first splat and a second splat associated with the object surfaces. The first splat and the second splat have a position and a normal vector. The method also includes forming an event line through the first splat and the second splat. The event line intersects the first splat and the second splat. The method further includes determining whether a visibility conflict exists between the first splat and the second splat. The method also includes separating the first splat and the second splat to different object surfaces if the visibility conflict exists, otherwise merging the first splat and the second splat to a single object surface.
