Problems solved by technology

However, the generation of details requires high-precision calculation and rendering. Due to the need to deal with large-scale particles, it will generate huge computational consumption in terms of fluid calculation and fluid surface construction.

Existing methods do not take advantage of the multi-precision features produced visually by fluid motion. It is difficult to perform effective fluid calculation and surface generation under the constraints of limited computing resources, which seriously affects the visual realism of animation.
