Abstract

We present in this paper the IMOGENE II system, a massively parallel Multi-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 SIMD systems, and allows a cost-effective, powerful and easily expandable system to be designed. The system consists of several SIMD Scan-Conversion Pipelines each connected to a Multi-Level Virtual Buffer, a Shading Unit computing true Phong Shading, a Virtual Accumulation Frame Buffer for anti-aliasing, and a classical Frame Buffer.
