Remote shading-based 3d streaming apparatus and method

A remote shading-based 3D streaming client, comprising:

• a 2D scene reconstruction unit for decoding network packets received from a 3D streaming server and 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 using color values at vertex coordinates of the 2D primitives;
• and
• a display unit for providing 3D and/or virtual reality contents using the determined screen pixel value.

A remote shading-based 3D streaming method, comprising:

• extracting 3D primitives from 3D scene data;
• converting the extracted 3D primitives into 2D primitives;
• constructing 2D scene data using the converted 2D primitives;
• constructing network packets from the 2D scene data, for transmission via network.
• reconstructing 2D scene data using the network packets, received from a 3D streaming server;
• extracting 2D primitives from the reconstructed 2D scene data;
• determining screen pixel values within a primitive region using color values of vertex coordinates of the 2D primitives;
• and
• providing 3D and/or virtual reality contents using the determined screen pixel value.
