  • Methods and systems for motion vectors in 3D graphics
    Patent number: 11941744
    Abstract: Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV1) and a 0-phase motion vector (MV0), each MV1 and MV0 having an associated depth value, to thereby form an MV1 texture and an MV0 texture; converting the MV1 texture to a set of MV1 blocks and converting the MV0 texture to a set of MV0 blocks; and outputting the set of MV1 blocks and the set of MV0 blocks for image processing.
    Type: Grant

  • METHODS AND SYSTEMS FOR 0-PHASE MOTION VECTORS IN 3D GRAPHICS
    Publication number: 20240087210
    Abstract: Various methods are provided for the generation of motion vectors in the context of 3D computer-generated images. In one example, a method includes generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV1) and a 0-phase motion vector (MV0), each MV1 and MV0 having an associated depth value, to thereby form an MV1 texture and an MV0 texture, each MV0 determined based on a camera MV0 and an object MV0, and outputting MV1 texture and the MV0 texture for image processing.

  • METHODS AND SYSTEMS FOR DUAL CHANNEL TRANSFER OF GAME
    Publication number: 20230245326
    Abstract: Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, based on a current frame to be rendered, a block-level motion vector with depth (MVD) texture comprising a set of block-level motion vectors each having an associated depth value, outputting the block-level MVD texture for image processing on a first channel, and outputting at least a portion of the current frame on a second channel.
