ABSTRACT
An urban 3D simulation engine with multi-GPU and multi-channel is designed and implemented to enhance the authenticity of urban 3D simulation scenes and to provide users with more feelings of scene immersion. The core procedures of engine is discussed and the optimization strategies including multi-GPU-CPU thread model, terrain loading and rendering strategies based on Tessellation, as well as screen subdivision and deferred rendering based parallel rendering strategies are elaborated. The performance of the engine is tested and analyzed with examples.

    In the watermarking schemes based on depth-image-based rendering (DIBR), the left-eye image and the right-eye image are rendered from the center image by shifting the pixels horizontally. The watermark embedded in the center image may be terrible disturbed, thus the watermark can not be detected...
