Abstract

Visibility culling is a crucial task for managing complex structure of three-dimensional scene especially in Geographic Information System (GIS) domain. According to the recent hardware specification, it is impractical to render large amount of dataset in real-time environment due to the quantity of dataset need to be faced exceeds the capability and performance of computer’s physical memory. Therefore, view frustum culling has been proposed in order to eradic ate the non-visible objects from pyramid of vision and subsequently speed up the system during the runtime process. It is based on predictive hierarchical quadtree structure and intersection test is done by calculating the distance between bounding volume of the object’s surfaces and the view volume. In this paper, we will adopt and adapt this approach to the 3D terrain objects for our deve lopment of 3D Virtual GIS.
