The FireFly™ particle system allows creating elaborate real-time particle effects in a true interactive 3D compositing space. Various emitters can be setup and applied with forces such as Wind & Gravity. The 3D and 2D particle systems are available on Pandoras Box Server systems whilst the Player systems support 2D particles only.

Basics information:
In order to use the Firefly Particles you have to add a Particle System to a video or graphic layer first. As a second step you may then drag one or several emitters onto the specific system.

Adding a Particle System to a layer

To add a particle system to your layer, drag and drop the 2D or 3D Particle System from the FireFly Particles Tab on the layer, just like you are adding FX to the layer. The particle system will appear right from the default layer parameters, see image below.

_img105

If you expand the layer in the device tree tab now, you will see that there is a new entry for the particle system in the folder “PS”, see image to the left.

With the particle system you define the environment, setting up the opacity of the system, Gravity and Wind. To see how these settings affect the emitters, you have to add at least one emitter.

Adding a Particle Emitter  to a Particle System

To add a particle emitter to your system, drag and drop the 2D or 3D Particle Emitter from the FireFly Particles Tab onto the system, not the layer:
- either into the Device Controls tab where you can see the faders of the Particle System
- or into the Device Tree tab, onto the entry that says "Particle System"

The particle system section is now enhanced by the emitter parameters.

Drag

Drag of particles; as drag is a force which decreases the velocity / speed of an object it resists the particle´s motion, thus it increases the influence of gravity and wind

Particle Examples

In the following examples these files are used:
_img107

In the examples only the parameter values different from the default values are mentioned.

Example 1:
_img108
Image above: Here the emitter type is set to “Point”, there is no gravity set for the particle system.

_img109
Image above: The particle systems gravity is now set to 155 – the emitters will fall down after they flew into positive Y direction.

_img110
Images above: The emitter type is changed to “Line”, with the Radius set to 12. No gravity.
Left) Viewed from the front, Right) viewed from the side.

_img111
Images above: The emitter type is changed to “Circle”, with the Radius set to 12. No gravity.
Left) Viewed from the front, Right) viewed from downside.
