Indicates the method of displaying particle models without using a scene graph.
Although the graphics library demo uses the scene graph feature and demo library rendering system, particles are displayed without using these features when using ParticleLowLayerDemo.
This is the particle version of LowLayerdemo included in 3D model demos.
Node coordinate system calculations can be omitted. Because the particle update process is also called separately, its easy to omit any given update process.
Unwanted overhead can be reduced by creating a container for collecting a series of particle nodes to represent an effect during an animation.
