Recent advances in visibility determination for large and complex virtual environments

Rendering large and complex virtual environments in real time remains a challenge as the complexity of models keeps growing. Visibility techniques such as occlusion culling can effectively reduce the rendering depth complexity. In my talk I'll survey recent advances in visibility determination. I'll focus on conservative and aggressive techniques and show how these techniques can be combined effectively with level of details and image-based techniques. I'll show how these new techniques can be accelerated by modern graphics cards to achieve interactive rendering of extremely complex scenes.
