Fireworks particle plugin helps AE make brilliant fireworks

Delirium de Fireworks is an excellent particle system designed to help aftereffects simulate the effects of large fireworks.

The basic idea of this plug-in is to control the flame by adjusting the launch position, the launch speed and the angle, and the flame flying to a certain altitude or velocity to explode into a gorgeous firework.

Fireworks special effects parameters are mainly image mode (picture pattern) Launch System (Launch System), explosion system (explosion system) and Sparkler system (scintillation System) environment (environment) Glow (luminous) composition.

The establishment fireworks fireworks effect mainly starts from the following three subsystems: The launch System, the explosion system, the flicker system.

Where the launch system controls the flying state of the fireworks, determine the speed and explosion point at the time of the explosion, which is a process from launch to explosion; the explosive system deals with the color, velocity and direction of the particles after the explosion, the duration of the explosion, the velocity of the particles falling after the explosion, and the simulation of the scintillation system to realize the real spark flicker

Let's look at a set of effect sequence diagrams first.

Effect sequence diagram

I. Establishment of synthetic documents COMP1

The settings are as follows:

Preset (Preset): small,160x120;

Width (width): 160 height (height): 120

Pixel Aspect Ratio (percentage of pixels): SQUARE PIXELS

Frame Rate (frames rate): 30

Duration (duration): 5S

Second, the establishment of fireworks solid layer black SOLID1

Layer->new solid, the size of the same COMP1, black color, the system has been automatically named the Dark Solid1.

Third, the introduction of special effects

Select Menu effect-> digieffects delirium->de Fireworks:

(i) The launch system controls the fireworks launch, the explosion speed, the altitude and so on parameter

Figure 1

Main parameter Description:

1, integrate over time: NOTE: If you set keyframes, you must check the key, if you do not set keyframes for other parameters, do not check this box, which can reduce rendering time.

2, the launch source has bottom of Layer (the bottom of the layer) point (dot) two.

Bottom of Layer: Fireworks will start firing from one o'clock at the bottom of the layer.

Point: Used in conjunction with the "Launch points", the fireworks will begin firing from the location of the launch site identified by "Launch".

3, Launch angle: Determine the angle of the fireworks launch, when the angle is 0, the fireworks will be fired vertically upward, for negative numbers, fireworks to the left, when a positive number, the fireworks to the right to launch.

The following are the different emission angles of the effect diagram.

The angle is negative and the angle is 0 positive.

Fig. 2 Effect of different launch angles

3. Explosion mode: There are two kinds of explode at height (explosion at a certain height) and explode at Speed (at a certain speed).

Explode at height mode together with "Explode height" to determine the height of the fireworks at the start of the explosion;

Explode at Speed mode "Explode Speed" to determine the speed at which the fireworks start to explode, the more negative the Explode Speed, the more the fireworks will move downward and the effect of the explosion is obvious.

(ii) Effect of explosive system on fireworks after explosion

Including the shape of the explosion, motion trajectory, color, etc.:

Fig. 3 parameter setting of explosive system

Main parameter Description:

1. Explosion shape: The shape of the explosion, there are explosive (explosive), Oval (oval) spherical (spherical) and geometrical (geometrical) four of shapes. The spherical effect looks more natural, geometrical is commonly used to establish special landscape fireworks.

2, Rotation: control particles around the explosion point of rotation, that is, the particle movement trajectory. There are four ways of Constant (invariant, continuous) varying (change) squiggle (flower body). One of the None (no rotation) means the trajectory of the fireworks is a straight line.

(iii) scintillation system

When the exploding particle lands, the fireworks system will increase the blink of the particle's tail, but will increase the rendering time.

Four Environment (Environment)

Adjust gravity, wind direction, air resistance and other parameters to better simulate the natural environment, create a sense of reality.

Five Glow (Glow)

Figure 6 setting of the luminous parameters

Special effects plug-in the use of key is to master the settings of different parameters, adjustment and comparison, as long as the parameters can be understood the meaning and role, we can freely create the effect of beautiful brightly-colored fireworks.
