Particle special effect rendering method and apparatus, and device and storage medium

An electronic device, comprising:

• at least one processor and a memory;
• wherein the memory stores computer-executable instructions;
• and
• when the at least one processor executes the computer-executable instructions stored in the memory, the at least one processor is caused to perform a particle effect rendering method,
• wherein the particle effect rendering method comprises:
• obtaining an object to be rendered;
• generating, based on the object to be rendered, a force field corresponding to the object to be rendered, wherein the force field comprises one or more positions, and a vector value corresponding to a position of the one or more positions is used to indicate a force applied to a particle when the particle is at the position;
• based on a 3D texture map of the force field, obtaining, according to a vector value corresponding to a first position of a particle in the force field in an image frame at a t-th moment, a second position of the particle in the force field in an image frame at a (t+1)-th moment, wherein t is a non-negative integer;
• and
• rendering and generating, according to the second position of the particle in the force field in the image frame at the (t+1)-th moment, the image frame at the (t+1)-th moment, so as to obtain a particle effect rendering result of the object to be rendered according to image frames corresponding to respective moments in a preset time period.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer-executable instructions, when a processor executes the computer-executable instructions, a particle effect rendering method is implemented,

• wherein the particle effect rendering method comprises:
• obtaining an object to be rendered;
• generating, based on the object to be rendered, a force field corresponding to the object to be rendered, wherein the force field comprises one or more positions, and a vector value corresponding to a position of the one or more positions is used to indicate a force applied to a particle when the particle is at the position;
• based on a 3D texture map of the force field, obtaining, according to a vector value corresponding to a first position of a particle in the force field in an image frame at a t-th moment, a second position of the particle in the force field in an image frame at a (t+1)-th moment, wherein t is a non-negative integer;
• and
• rendering and generating, according to the second position of the particle in the force field in the image frame at the (t+1)-th moment, the image frame at the (t+1)-th moment, so as to obtain a particle effect rendering result of the object to be rendered according to image frames corresponding to respective moments in a preset time period.
