Real-time water rendering using projected grid
Zhao Ya Peng · Cehui kexue · 2008
This thesis will examine how a large water surface can be rendered in an efficient manner using modern graphics hardware.We often treat the water surface as a height field for simplification.To allow spatial scalability,different methods of Level-Of-Detail(LOD) are often used.The thesis presents an alternative technique called projected grid.It creates a grid mesh whose vertices are even-spaced,not in world-space,which is the traditional way but in post-perspective camera space.This will deliver a polygonal representation that provides spatial scalability along with high relative resolution without resorting to multiple levels of detail.
