Particle systems in Moldeo
Image via Wikipedia
According to Wikipedia, particle systems are:
“The term particle system refers to a computer graphics technique to simulate certain fuzzy phenomena, which are otherwise very hard to reproduce with conventional rendering techniques. Examples of such phenomena which are commonly replicated using particle systems include fire, explosions, smoke, moving water, sparks, falling leaves, clouds, fog, snow, dust, meteor tails, hair, fur, grass, or abstract visual effects like glowing trails, magic spells, etc.”
In Moldeo, you can implement particle systems in your projects. You just need to add the particle system plug-in to your project and enable it. I will walk show you how to modify a project with a particle system, and how its main parameters work.
First, open the Simples Project in the Examples Menu of Moldeo Director. After opening the file, you have to disable the icon (just to make the project more clear).
Then, open the parameters page of the particle effect by clicking on the particlesimple effect on the Project tab. The first parameter to modify is maxage, which in miliseconds defines how long the different particles will be displayed.
For instance, change maxage to 10,000 (10 seconds)
Then change the emitionrate up to 20. This parameters tells the system how many particles will be created on every emitionperiod which defines in milliseconds how long it takes to create the particles. Change the emitionperiod up to 100 (0.1 seconds)
If you would like to create the particles at a faster pace, change randomvelocity up to 200 and see what happens. You can also try different values; such as 2, 5, 10 and 100 for the parameters randomvelocityx, randomvelocityy and randomvelocityz.
Then you can change other parameters, such as height and width in order to make your particles smaller or larger.
Don’t feel afraid to modify different parameters and have fun with it.
