  • Ray tracing core and method for processing ray tracing
    Patent number: 8836702
    Abstract: A ray tracing core comprises a ray tracing unit (RTU), a control unit, and a tree build unit (TBU). The ray tracing unit performs ray tracing based on a spatial partitioning structure. The control unit calculates the degree of complexity of the spatial partitioning structure by monitoring the load state of the ray tracing unit. The tree build unit builds the spatial partitioning structure having the degree of complexity which is calculated. The load state is determined based on a frame rate which is processed in the pertinent unit. The spatial partitioning structure applies a K-dimensional tree. For example, the degree of complexity can be modified according to either the maximum primitive number of a leaf node with respect to a K-dimensional tree structure or a tree depth.

  • ROY TRACING APPRATUS AND METHOD
    Publication number: 20140176550
    Abstract: A method for selecting a MIP-map level is used for Texture Mapping based on Global Illumination. The method for selecting the MIP-map level confirms Object information on at least one object on a screen. The object information can include the number, shape, and the composition of objects on the screen, and/or the spatial position of a relevant object on the screen. Based on the object information, a MIP-map level selection algorithm is determined. The MIP-map level selection algorithm includes ray tracing and/or distance measuring, wherein the ray tracing selects the MIP-map based on the Differential value of adjacent rays, and the distance measuring can select a MIP-map by calculating the distance at which the ratio of pixels and texels reach 1:1. Based on the determined method, the MIP-map level is selected.

  • METHOD AND APPARATUS FOR VoIP VIDEO COMMUNICATION
    Publication number: 20140132700
    Abstract: In a Voice over Internet Protocol (VoIP) video communication method and apparatus, first and second VoIP-based terminals store video event indexes and images mapped thereto with respect to state information of a user and terminal, and establish a session using session establishment information defining the video event. The first terminal then transmits a data packet including the video event index, and the second terminal receives the data packet and outputs an image mapped to the video event index of the images stored in advance. Thus, by transmitting and receiving a predefined index alone without transmitting user and terminal states as a real time data-type image, the VoIP video communication method and apparatus prevent unnecessary waste of bandwidth in video communication.
