METHOD AND SYSTEM FOR EFFICIENTLY RENDERING 3D PARTICLE SYSTEMS FOR WEATHER EFFECTS

摘要

To provide a method for generating graphics in a three-dimensional (3D) virtual environment.SOLUTION: A method comprises: receiving, with a processor, a first camera position in a 3D virtual environment and a first viewing direction in the 3D virtual environment; receiving, with the processor, weather data including a first precipitation information according to a first geographic region corresponding to the first camera position in the 3D virtual environment; defining, with the processor, a boundary geometry dimensioned so as to cover a field of view from the first camera position in the first viewing direction at a first position that is a first distance from the first camera position in the first viewing direction; and rendering, with the processor, a 3D particle system having features depending on the first precipitation information in the 3D virtual environment depicting precipitation only within the boundary geometry.SELECTED DRAWING: Figure 2
