The invention is further described with reference to the following specific examples:
the invention relates to a system for realizing the diversification of particle expression, which mainly provides two directional ideas, one is to support various emitter settings in an emitter module, the other is to add an influencer module, and a custom influencer is added in the module to influence the particle attribute of the particle emission process.
The general implementation of the transmitter module direction steps: based on the basic emitter module, the original setting of a single emitter is changed, a plurality of emitters are realized, the initialized particle array is added into each emitter according to a certain rule, the birth position attribute of each particle in the array is modified, and the work of the emitter module is completed. The specific implementation steps are as follows: each emitter presets parameters such as emission rate, duration of particles in the emitter, etc. Traversing the emitter array, multiplying the time elapsed for each frame by the emitter emission rate and rounding down to obtain how many particles the emitter needs to emit per frame, and so on, and the rest particles are distributed to different emitters according to the value. The modification of the particle birth position is realized according to the requirements of different emitters, such as a circular emitter, a radius parameter r is transmitted to the circular emitter, a percentage a between 0 and 1 and a random degree b are obtained through random numbers, a is multiplied by the radius r to obtain a random length ra, and ra is multiplied by sin values and cos values of random angles to obtain final position information, so that the birth position of the particle in the emitter is determined.
The implementation steps of the direction of the affector module are as follows: firstly, setting three most basic modules of a particle system according to the original flow: the device comprises an initialization module, an emitter module and a rendering module, wherein final attribute data of particles passing through the modules are calculated and stored in a predefined storage medium temporarily. And adding an influencer module, wherein the influencer module comprises various types of influencers, each influencer sequentially reads the particle attribute in the storage medium according to the number, and the previous influencer reads and processes the particle attribute data and then transmits the data to the next influencer for gradual iteration. The order of the influencers in this process will influence the final behavior of the particles. Finally, the CPU transmits the relevant attribute data (position, material, scaling, rotation and color) of the particles to the GPU and draws the data.
The application scene of the invention is as follows:
the implementation of the direction of the affector module takes as an example the rendering of a particle system affected by a plurality of affector, as shown in fig. 3, there is a particle system in the scene that is emitted linearly upwards, the affector module of the particle does not add any affector, the particle already contains the necessary particle properties. The influencer module is turned on and a linear force (linear force) implemented in advance according to an algorithm is added, and as shown in fig. 4, the influencer can influence the movement speed of the particles during each frame update, so that the whole particles are offset. In addition, a line drop effector (line segment dither) is added, which is implemented in advance and can dither particles in a certain direction at a specific dither frequency, and as shown in fig. 5, the two types of effectors are combined to change the existing movement speed of the particles, and a dither effect can be generated.
The implementation of the emitter module direction takes as an example the rendering of a particle system with a plurality of emitters, as shown in fig. 6, a point emitter in the scene that only supports the emission of particles from the origin. After modifying its emitter type to a circular emitter, as shown in fig. 7, the distribution of the particles appears circular, and the emitter module is modified according to the emitter direction scheme to achieve two or more emitter compatibility, as shown in fig. 8, the distribution of the particles is both at the origin and at the circle.
