Class EmitterMeshConvexHullShape

java.lang.Object

com.jme3.effect.shapes.EmitterMeshVertexShape

com.jme3.effect.shapes.EmitterMeshFaceShape

com.jme3.effect.shapes.EmitterMeshConvexHullShape

All Implemented Interfaces:

EmitterShape, Savable, JmeCloneable, java.lang.Cloneable

public class EmitterMeshConvexHullShape
extends EmitterMeshFaceShape

This emitter shape emits the particles from the given shape's interior constrained by its convex hull (a geometry that tightly wraps the mesh). So in case of multiple meshes some vertices may appear in a space between them.

Constructor Detail

EmitterMeshConvexHullShape

public EmitterMeshConvexHullShape()

Empty constructor. Sets nothing.

EmitterMeshConvexHullShape

public EmitterMeshConvexHullShape(java.util.List<Mesh> meshes)

Constructor. It stores a copy of vertex list of all meshes.

Parameters:

meshes - a list of meshes that will form the emitter's shape

Method Detail

getRandomPoint

public void getRandomPoint(Vector3f store)

Randomly selects a point inside the convex hull of a randomly selected mesh.

Specified by:

getRandomPoint in interface EmitterShape

Overrides:

getRandomPoint in class EmitterMeshFaceShape

Parameters:

store - storage for the coordinates of the selected point

getRandomPointAndNormal

public void getRandomPointAndNormal(Vector3f store,
                                    Vector3f normal)

Randomly selects a point inside the convex hull of a randomly selected mesh. The normal argument is not used.

Specified by:

getRandomPointAndNormal in interface EmitterShape

Overrides:

getRandomPointAndNormal in class EmitterMeshFaceShape

Parameters:

store - storage for the coordinates of the selected point

normal - not used in this class
