| Class | Description | 
|---|---|
| EmitterBoxShape | |
| EmitterMeshConvexHullShape | 
 This emitter shape emits the particles from the given shape's interior constrained by its convex hull
 (a geometry that tightly wraps the mesh). 
 | 
| EmitterMeshFaceShape | 
 This emitter shape emits the particles from the given shape's faces. 
 | 
| EmitterMeshVertexShape | 
 This emitter shape emits the particles from the given shape's vertices
