| 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 |
