This paper explores the benefits that can be achieved for stereoscopic visualization when using occlusion culling strategies. The virtual environments analysed in this paper are complex mechanical sets that are not densely occluded. Those which are built up by dense geometric sets like aerospace engines composed of thousands of components and millions of polygons. The algorithm uses occlusion queries and succeeds in improving the frame rate of the stereoscopic visualization with an effective scheduling of the queries. Different coherences, including stereo coherence, are used to achieve this effective scheduling. An aggressive approach has been also validated for inclusion in the proposal. The occlusion culling algorithm can be easily implemented and provides a significant boost in performances.
