A method for encoding video for streaming includes receiving a plurality of sequential image frames generated by a 3D graphics rendering engine. Graphics rendering contexts are obtained, including pixel depth map, rendering camera parameters, and camera motion from the 3D rendering engine. The method next entails selecting key frames among the plurality of sequential image frames, interpolating non-key frames via 3D image warping, and encoding all key frames and warping residues of non-key frames. The system is implementable on a server linked to a mobile user device for receiving the encoded frame data. The mobile user device is configured to decode the encoded frame data and display a corresponding image to a user of the mobile user device.
