Abstract

The invention discloses a water body interactive mapping method which comprises the following steps: emitting particles through a particle emitter, observing by using an orthogonal camera, and simulating fluctuation diagrams of two colors; converting the fluctuation diagrams of the two colors into a Bump map; calculating to obtain a corresponding normal map according to the Bump map; and realizinga water body interaction effect according to the obtained normal map and illumination calculation. The invention further discloses a water body interaction mapping system, an electronic device and acomputer readable storage medium. Therefore, vertex displacement calculation of traditional water body interaction can be replaced, and the water body interaction effect is achieved mainly through normal mapping calculation without depending on the number of vertexes.

Description

technical field [0001] The present application relates to the technical field of graphic processing, and in particular to a water body interactive mapping method, system, electronic device and computer-readable storage medium. Background technique [0002] In computer graphics processing technology, especially in the game development process, water body interaction is a common effect, mainly rendering the shape of the water surface when the water body interacts with objects, which is an important link that can show the details of the game. However, water body interaction is often a difficult point in water surface production technology. Traditional water body interaction effects are generally based on vertex movement, and the vertex displacement is calculated with the wave equation. This implementation method requires a high number of vertices and faces, and in the case of a low number of faces, it is impossible to simulate water bodies by modifying vertices. [0003] It s...
