particle sprites.</p><p>Class is designed to provide same functionality as SpriteKit&rsquo;s SKEmitterNode, just in 3D space. In fact, you can instantiate R4EmitterNode object from SKEmitterNode object and all conversion to 3D space is done automatically. That means that you can use Xcode&rsquo;s Particle editor to create particle effects, save them in .sks files and instantiate R4EmitterNode object from them.</p><p>During conversion, emitter&rsquo;s position, speed and acceleration values are divided by 10
