Problems solved by technology
In PBF simulation, the collision between the fluid and the rigid body is usually realized by means of signed distance functions (SDF). However, this method needs to calculate the SDF of the rigid body model in the three-dimensional space, which is complicated to calculate and takes up a lot of video memory. Moreover, the SDF of the model needs to be recalculated after the rigid body model moves, which takes a long time
If this method is applied to a mobile terminal, since the computing and storage resources on the mobile terminal are very limited, this method usually cannot meet the resource requirements and real-time requirements of the mobile terminal.

The invention provides a dynamic fluid effect processing method and device, an electronic device and a readable medium, and relates to the technical field of computers. The method comprises the following steps of displaying a first object and a fluid in a user display interface; acquiring the position of each model particle in an object model corresponding to the first object; acquiring the position of each fluid particle corresponding to the fluid; and when the first object collides with the fluid, for each fluid particle, adjusting the position of the fluid particle according to the position of the model particle colliding with the fluid particle so as to dynamically display the motion change of the fluid on the user display interface. According to the technical scheme, when the first object collides with the fluid, the positions of the fluid particles are adjusted according to the positions of the model particles colliding with the fluid particles, and the SDF of the first object does not need to be calculated, so that the calculation process is simplified, and the motion change effect of the fluid can be presented in real time on a mobile terminal.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular, the present disclosure relates to a dynamic fluid effect processing method, device, electronic equipment and computer readable medium. Background technique [0002] Computer Graphics (CG) is the science of using mathematical algorithms to convert two-dimensional or three-dimensional graphics into a raster form for computer displays. Simply put, the main research content of computer graphics is to study how to represent graphics in the computer, and to use the computer to calculate, process and display the related principles and algorithms of graphics. [0003] Fluid simulation based on physical animation is an important research field in computer graphics. Position Based Fluids (PBF) simulation is widely used in 3D fluid simulation due to its advantages of unconditional stability and allowing large time steps. In PBF simulation, the collision between the fluid and ...
