CPUParticles
============
**Inherits:** :ref:`GeometryInstance<class_GeometryInstance>` **<** :ref:`VisualInstance<class_VisualInstance>` **<** :ref:`CullInstance<class_CullInstance>` **<** :ref:`Spatial<class_Spatial>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
CPU-based 3D particle emitter.
.. rst-class:: classref-introduction-group
Description
-----------
CPU-based 3D particle node used to create a variety of particle systems and effects.
See also :ref:`Particles<class_Particles>`, which provides the same functionality with hardware acceleration, but may not run on older devices.
\ **Note:** Unlike :ref:`Particles<class_Particles>`, the visibility rect is generated on-the-fly and doesn't need to be configured by the user.
