Abstract

A rendering method includes first constructing a first phase field based on information about a to-be-rendered zone, where the first phase field indicates density distribution in the to-be-rendered zone; obtaining acting force on the to-be-rendered zone, where the fluid flows under action of the external force; obtaining, with reference to the first phase field, velocity distribution of each point in the to-be-rendered zone; performing an advection operation on the first phase field based on the velocity field to obtain a second phase field, wherein the second phase field comprises density distribution obtained by performing the advection operation on the fluid in the to-be-rendered zone; and rendering the to-be-rendered zone based on the second phase field to obtain a rendering frame.
