REMOTE SHADING-BASED 3D STREAMING APPARATUS AND METHOD

A remote shading-based three-dimensional (3D) streaming apparatus includes a 3D streaming server and a 3D streaming client. The 3D streaming server includes a 3D primitive extraction unit for extracting 3D primitives from 3D scene data provided thereto; a 2D primitive conversion unit for converting the extracted 3D primitives into 2D primitives; a 2D scene and network packet construction unit for constructing 2D scene data and network packets; a network packet transmission unit for transmitting the network packets to a 3D streaming client. The 3D streaming client includes a 2D scene reconstruction unit for reconstructing 2D scene data from the network packets; a 2D primitive extraction unit for extracting 2D primitives from the 2D scene data; a 2D rasterizing unit for determining screen pixel values within a primitive region; and a display unit for providing 3D and/or virtual reality contents using the determined screen pixel value.
