Method Details

getCentroid

public Vec3 getCentroid()

Copy the centroid of the face. The face is unaffected. (native attribute: mCentroid)

Specified by:

getCentroid in interface ConstChbFace

Returns:

a new location vector

getFirstEdge

public ChbEdge getFirstEdge()

Access the first edge of the face. The face is unaffected. (native attribute: mFirstEdge)

Specified by:

getFirstEdge in interface ConstChbFace

Returns:

a new JVM object with the pre-existing native object assigned, or null if none

getNormal

public Vec3 getNormal()

Copy the normal of the face. The face is unaffected. (native attribute: mNormal)

Specified by:

getNormal in interface ConstChbFace

Returns:

a new vector whose length is 2 times the area of the face

isFacing

public boolean isFacing(Vec3Arg point)

Test whether the face is facing the specified point. The face is unaffected.

Specified by:

isFacing in interface ConstChbFace

Parameters:

point - the location to test (not null, unaffected)

Returns:

true if facing the test point, otherwise false
