High performance commodity components are available today to build clusters powerful enough to run high performance virtual reality applications. But cluster programming is time consumming and error prone. Virtual reality platforms that hide the complexity of the cluster architecture and provide automatic parallelization schemes are required. We present in this paper two open source softwares, Net Juggler and SoftGenLock. The association of these libraries makes possible to run a VR Juggler application with active stereo and multi displays on a commodity component PC cluster. Net Juggler turns a cluster running the VR Juggler platform on each node into a single VR Juggler image cluster. Application parallelization is transparent to the user. SoftGenLock provides software genlock and quad buffer page flipped stereo, without requiring specific hardware or graphics card driver source code. The performed tests show these softwares do no introduce a significant overhead. 1
