public abstract class AbstractBox extends Mesh
A Box
is defined by a minimal point and a maximal point. The eight
vertices that make the box are then computed, they are computed in such
a way as to generate an axis-aligned box.
This class does not control how the geometry data is generated, see Box
for that.

It's a one-to-one ratio, where each plane of the box has its own copy of the texture. That is, the texture is repeated one time for each face.
protected abstract void doUpdateGeometryVertices()
These eight points are determined from the minimum and maximum point.

public final void updateGeometry()
For example, if you call getXExtent().x = 5.0f
then you will
need to call this method afterwards in order to update the box.
public final void updateGeometry(Vector3f center, float x, float y, float z)
Note that the actual sides will be twice the given extent values because the box extends in both directions from the center for each extent.
center
- the center of the box.x
- the x extent of the box, in each directions.y
- the y extent of the box, in each directions.z
- the z extent of the box, in each directions.public final void updateGeometry(Vector3f minPoint, Vector3f maxPoint)
The box is updated so that the two opposite corners are minPoint
and maxPoint
, the other corners are created from those two positions.
minPoint
- the new minimum point of the box.maxPoint
- the new maximum point of the box.public void read(JmeImporter e) throws java.io.IOException
