By reducing the data amount to graph pipeline, the rendering efficiency can be improved significantly. We present a novel frustum culling approach (2D frustum culling) for the scene that has only one layer of objects, such as forest. This scene meets the condition `when projecting all the objects to one plane, the point on projected plane corresponds to only one object'. Our approach contains three...
The development of virtual scene involves too many object; however, in most cases they share some common parts. After researching the modeling method of sky and terrain, one basic framework of virtual scene's development is put forward. The framework covers both the modeling and rendering technique of sky and terrain, and any operation on camera. Detailed design is presented in relative section, by...
