Abstract: We present in this paper the IMOGENE II system, a massively parallelMulti-SIMD graphics system. This architecture uses a new rasterization scheme combining Object Parallelism and Parallel Virtual Buffers. This scheme leads to a better efficiency than other massively parallel SHvlD systems, and allows a cost-effective, powerful and easily expandable system to be designed. The system consists of several SIMD ScanConversionPipelines each connected to a Multi-Level Virtual Buffer, a Shading Unitcomputing true Phong Shading, a Virtual Accumulation Frame Buffer for anti-aliasing,and a. classical Frame Buffer.
