Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

First, the technical terms in the embodiments of the present invention are introduced:

Particle System: Particle system is a technique in computer graphics used to simulate common physical phenomena. A particle system is composed of many particles. By controlling the properties and states of each particle, the macroscopic phenomenon of the particle system can finally be formed.

Ice crack style image: Ice crack is an ancient Chinese porcelain firing process. It is called because of the cracked pattern of ice, the layered slivers, and the three-dimensional effect. It has a typical beauty of turning decay into magical incompleteness. An ice crack style image refers to an image with an ice crack texture.

The inventor found that the generation of ice crack style images mostly relies on traditional manual processes, and there are few other ways to generate ice crack style images. People cannot easily obtain ice crack style images. Dissemination, application and innovation in fields such as art have been greatly restricted. To solve this problem, the inventor proposes a method for generating an ice crack style image. FIG. 1 is a schematic flowchart of a method for generating an ice crack style image in an embodiment of the present invention. As shown in FIG. 1 , the method includes the following steps:

Step 101, initialize the particle system and the force field of the particle system;

Step 102, according to the force field of the particle system, guide the force movement of the particles in the particle system;

Step 103: Update the trajectory of the particle in the particle system according to the motion state of the particle in the particle system;

Step 104 , after all particles in the particle system finish moving, generate an ice crack style image according to the trajectories of all particles in the particle system.

It can be known from the process shown in FIG. 1 that in the embodiment of the present invention, the particle system and the force field of the particle system are initialized; according to the force field of the particle system, the force movement of the particles in the particle system is guided; The motion state of the particle, and the trajectory of the particle in the particle system is updated; after all the particles in the particle system have finished moving, the ice crack style image is generated according to the trajectory of all the particles in the particle system. The embodiment of the present invention generates an ice crack style image through a particle system, the method is simple and the effect is remarkable, so that the generation of the ice crack style image no longer depends on the traditional manual process, people can obtain the ice crack style image more conveniently, and professionals can use the ice crack style image. Crack-style images are used for secondary creation, and non-professionals can use ice-crack-style images for social entertainment, which facilitates the dissemination, application and innovation of ice-crack-style images in industrial manufacturing, artistic creation, and the Internet industry.

During specific implementation, first, initialize the particle system and the force field of the particle system. For example, use a programming language to initialize the particle system and the force field of the particle system. The programming language may include programming languages such as C language, C++ language, and JAVA language, which are not specifically limited in this specification.

In one embodiment, initializing the particle system includes: initializing the position, velocity, charge amount, and positive and negative charge of particles in the particle system. Particles have properties such as position, velocity, acceleration, charge, and electropositivity. The behaviors of particles are: moving under the action of a force field, that is, moving positions. When each particle is generated, its position, velocity, charge, and positive and negative properties are initialized (the charge and positive and negative properties are randomly generated according to the program running time, and continue to change randomly in each subsequent update). The acceleration of particles is produced by the action of the force field.

FIG. 2 is a diagram of a specific example of a method for generating an ice crack style image in an embodiment of the present invention. As shown in FIG. 2 , in this example, there are four primary particles when initializing the particle system, and the speed directions of the four particles are specified as Along the positive and negative directions of the x-axis and the y-axis, the positions of the four particles are all in the middle of the force field, and the velocity, charge, and positive and negative electrical properties are randomly generated.

It should be noted that, in one embodiment, the particles in the particle system are affected by the force field of the particle system. In other embodiments, the particles in the particle system are not only affected by the force field of the particle system, The interaction between particles also needs to be considered, such as same-sex repulsion, opposite-sex attraction, etc. In the following embodiments, the particles in the particle system are affected by the force field of the particle system as an example for description.

In one embodiment, initializing the force field of the particle system includes: initializing the magnetic induction intensity of the force field of the particle system. For example, when initializing the force field of a particle system, configure the magnetic induction of the force field. For example, a magnetic field with a constant magnetic induction intensity of (0,0,-1) can be given.

In one embodiment, according to the following formula, according to the force field of the particle system, the force movement of the particles in the particle system is guided, including:

F=qV×B;

Among them, F is the force on the particle in the particle system; q is the charge of the particle in the particle system; V is the velocity of the particle in the particle system; B is the magnetic induction intensity of the force field of the particle system.

After initializing the particle system and the force field of the particle system, the force movement of the particles in the particle system is guided according to the force field of the particle system; the trajectory of the particles in the particle system is updated according to the motion state of the particles in the particle system.

For example, after initializing the particle system and the force field of the particle system, all particles are accelerated by the force field and start to move, and the position, velocity, charge, positive and negative charge, and trajectory of all particles in the particle system are updated in real time. .

In one embodiment, the force movement of the particles in the particle system is guided according to the force field of the particle system, and the trajectory of the particles in the particle system is updated according to the motion state of the particles in the particle system, which may include:

According to the force field of the particle system, guide the force movement of the first-generation particles in the particle system, and update the trajectory of the first-generation particles in the particle system according to the motion state of the first-generation particles in the particle system;

After the primary particle in the particle system finishes moving, the child particle is generated on the trajectory of the primary particle;

According to the force field of the particle system, guide the force movement of the child particles in the particle system, and update the trajectory of the child particles in the particle system according to the motion state of the child particles in the particle system;

After the child particles in the particle system end their motion, the grandchild particles are generated on the trajectory of the child particles;

According to the force field of the particle system, guide the force movement of the grandchild particles in the particle system, and update the trajectory of the grandchild particles in the particle system according to the motion state of the grandchild particles in the particle system;

And so on, until all particles in the particle system stop moving.

In one embodiment, generating child particles on the trajectory of the first generation particle may include:

Daughter particles are alternately generated by the set length thresholds on both sides of the trajectory of the primary particle, wherein the initial velocity direction of the child particle is perpendicular to the tangent direction of the trajectory of the primary particle that generates the child particle;

Spawns grandchild particles on their trajectories, which can include:

The length thresholds set on both sides of the descendant particle's trajectory alternately generate grandchildren particles, wherein the initial velocity direction of the grandchildren particles is perpendicular to the tangent direction of the trajectory of the descendant particles that generate the grandchildren particles.

The child particles continue to move until the movement ends. Those skilled in the art should know that the length threshold can be preset according to actual requirements, which is not limited in this specification.

As shown in FIG. 3 , in this example, the next-generation particles are alternately generated by the length thresholds set at intervals on both sides of the trajectory of the particle that has ended motion. .

Then, grandchild particles are generated on the trajectory of these child particles, and so on and so forth, until all the particles stop moving. The growth process of the particle system ends. FIG. 4 is a diagram of a specific example of a method for generating an ice crack style image according to an embodiment of the present invention, and FIG. 4 shows the trajectories of all particles after the growth process of the particle system in this example ends.

In one embodiment, when the particle in the particle system moves to the boundary of the canvas that generates the ice crack style image, or moves to the trajectory of other particles, it is determined that the particle ends the movement.

For example, when a particle in the particle system moves to the border of the canvas where the ice crack style image is generated, it is determined that the particle ends its movement, and the particle is deleted from the particle system.

For another example, when a certain particle in the particle system moves to the trajectory of other particles, it is determined that the particle ends the movement, and the particle is deleted from the particle system.

In one embodiment, before generating the ice crack style image according to the trajectories of all particles in the particle system, the method further includes:

Sets the background of the canvas that generates the ice crack style image to a preset color, or to an image entered by the user.

After all particles in the particle system have finished moving, an ice crack style image is generated according to the trajectories of all particles in the particle system.

For example, set the background of the canvas for generating the ice crack style image to white, and after all particles in the particle system have finished moving, generate the ice crack style image according to the trajectories of all particles in the particle system. FIG. 5 is a diagram of a specific example of a method for generating an ice crack style image according to an embodiment of the present invention. FIG. 5 shows an ice crack style image generated when the background of the canvas for generating the ice crack style image is set to white.

For another example, the background of the canvas for generating the ice crack style image is set as the image input by the user, and after all particles in the particle system finish moving, the ice crack style image is generated according to the trajectory of all particles in the particle system.

Step 703, update the position, velocity, charge, and positive and negative charge of the particle;

Step 704, update the trajectory of the particle;

Step 705, determine whether the particle ends movement, i.e. determine whether the particle moves to the canvas boundary of the ice crack style image, or moves to the trajectory of other particles, if so, determine that the particle ends movement; if not, return to step 701 to continue the cycle;

Step 706, if the particle ends moving, delete the particle from the particle system;
