Lazy Occlusion Grid Culling

  • Publication Type: Technical Report
  • Keywords: real-time rendering, hardware acceleration, image-based, visibility, occlusion culling

Abstract
THIS TECHNICAL REPORT IS OUTDATED AND HAS BEEN SUPERSEDED BY TR-186-2-01-02. We present Lazy Occlusion Grid Culling, a new image-based occlusion culling technique for rendering of very large scenes which can be of general type. It is based on a low-resolution grid that is updated in a lazy manner and that allows fast decisions if an object is occluded or visible together with a hierarchical scene-representation to cull large parts of the scene at once. It is hardware-accelerateable and it works efficiently even on systems where pixel-based occlusion testing is implemented in software.
