The createSprayEmitter method sets the radius and height of the cylinder, creates a new SprayParticleEmitter object which is assigned to the particleEmitterType property. Any particle with a start position inside the blue region is emitted horizontally. In order to determine where a particle is emitted from, the cylinder is divided into two regions as in the diagram below.Īny particle with a start position inside the red region is emitted in the direction from the center to the particle. You can create your own ParticleEmitterType by extending IParticleEmitterType and assigning it to particleEmitterType, overriding the default methods startDirectionFunction and startPositionFunction.īelow is an example to create a new spray emitter which will send streams of particles out of the top, bottom and sides of a cylindrical region. You use the startDirectionFunction and startPositionFunction as methods for objects of this type to determine the region of space that the particles are emitted from and their direction of travel. These objects are assigned to a new property particleEmitterType of the particleSystem. Examples of this type of object are sphereParticleEmitter and coneParticleEmitter which are produced by using createSphereEmitter and createConeEmitter. ![]() Starting from Babylon.js V3.2 you can create a new object of type IParticleEmitterType into the particle system. In this video tutorial from Vox Lab, we see how to create a simple smoke source using the particle playground effect. Creating and Tracking Smoke in Adobe After Effects CS6. a custom event defined by body() comp // every time an obj with tag bomb hits the. In the following article, we’ll take a look at a few different ways to create smoke in After Effects. } Growing Particles Particle Emitter Type Play with it yourself or check out the examples in the Playground. The start direction function has the default form Since Babylon.js V3.2 you can use the first two, startDirectionFunction and startPositionFunction, in creating a new particle emitter type as was done with the createBo圎mitter, createSphereEmitter and createConeEmitter. You can directly attach all these functions to the particleSystem. updateFunction: provides an update to each particle on each frame and can affect position, color, age, size etc. ![]()
