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