Method Details

getConvexRadius

public float getConvexRadius()

Return the convex radius.

Returns:

the added distance (in meters)

getSupport

public Vec3 getSupport(float dx,
 float dy,
 float dz)

Calculate a support vector for the specified direction.

Parameters:

dx - the X component of the input direction

dy - the Y component of the input direction

dz - the Z component of the input direction

Returns:

a new location vector relative to the shape's center of mass

getSupport

public Vec3 getSupport(Vec3Arg direction)

Calculate a support vector for the specified direction.

Parameters:

direction - the input direction (not null, unaffected)

Returns:

a new location vector relative to the shape's center of mass

getSupportBulk

public void getSupportBulk(FloatBuffer directions,
 FloatBuffer storePoints)

Calculate support vectors for the specified directions.

Parameters:

directions - the input directions (not null, capacity a multiple of 3, unaffected)

storePoints - storage for location vectors relative to the shape's center of mass (not null, same capacity as directions)
