public class ParticleSystem
extends X3DConcreteNode
implements ParticleSystem

ParticleSystem specifies a complete particle system.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. ParticleSystem node tooltip: (X3D version 3.2 or later) [X3DShapeNode] ParticleSystem specifies a complete particle system. It can contain Appearance for particle appearance, a geometry node if gemoetryType='GEOMETRY', a color field with Color|ColorRGBA node for changing base color over each particle's lifetime, a texcoord TextureCoordinate node to control texture coordinates of provided texture(s) in the Appearance node over time, a single emitter X3DParticleEmitterNode, and an array of physics X3DParticlePhysicsModelNode nodes.

• Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/concepts.html#ExecutionModel
• Hint: Wikipedia, particle system https://en.wikipedia.org/wiki/Particle_system

Note that SFColor provides a variety of color constants.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
