Extract trapcode's Particle System Operation

I. particle generator

Particle generator: used to generate particles and set attributes such as particle size, shape, type, initial speed, and direction.

1. Number of particles: the number of particles produced per frame can be controlled.

2. particle generator type: there are seven types of particle generators: Point, box, sphere, grid, light, layer, and layer grid.

3. particle position: 3D coordinates.

4. Particle Motion Direction:

5. particle beam divergence: directional, bi-directional, disc, and outwards. It does not work when the beam direction is set to uniform and the light is used as the particle generator.

6. particle emission direction:

7. Initial Velocity of newly generated particles: it can be set to a random value.

8. Particle inheriting speed of the particle generator: You can set the multiplication parameter.

9. particle generator size:

Ii. Particles

All external attributes of a particle, such as size, transparency, color, and changes to these attributes throughout the lifecycle.

1. Life: the random value of life.

2. particle types: sphere, Glow sphere, Star, cloudlet, and smokelet), custom shape (custom, custom colorize, custom fill) and so on.

3. Sphere/cloudlet/smokelet feather: controls the softness (softness) of sphere, cloud, and smoke particles. The larger the value, the more authentic the particles are.

4. Particle rotation and rotation speed: Only applicable to star, cloudlet, smokelet, and custom particles.

5. Particle Size: Random size value and size change.

6. Particle transparency: Random transparency value and transparency change.

7. Color: color change.

8. Particle synthesis: ordinary (masked), overlay (brightness and other overlay), and screen. The last two are very useful for generating light and flame effects.

Iii. physical attributes

1. Physical Model: Air and bounce (collision)

Air: air resistance, rotation, wind field, irregular size, irregular location, interference field (interfering with the movement of particles, such as black holes ).

Bounce: collision mode: Bounce (bounce coefficient), slide (friction coefficient), and disappear.

2. Gravity coefficient:

3. Acceleration:

Iv. Motion Blur

Before rendering, the system inserts additional particles directly into the particle queue.

1. Two Motion Blur modes: linear line and interpolation (displacement and other interpolation ).

5. Additional launch options

Particle luminescence degree.

...

And so on.
