getValue
public double[] getValue()
-
setValue
public SbBox2d setValue(double[] components)
-
setValue
public SbBox2d setValue(double[] components, int startIndex)
-
setValue
public void setValue(SbBox2d copyFrom)
-
isEmpty
public boolean isEmpty()
Returns true if the box is empty, and false otherwise. Note: Setting the box to all zeros does not make it "empty". Use themakeEmpty()
method. (This method only returns true if the maximum X value is less than the minimum X value.)
-
makeEmpty
public void makeEmpty()
Makes an empty box.
-
setBounds
public void setBounds(double xmin, double ymin, double xmax, double ymax)
Sets the corners of the box.
-
toArray
public static SbBox2d[] toArray(long nativeArray, long length)
-
equals
public boolean equals(java.lang.Object obj)
- Overrides:
equals
in classjava.lang.Object
-
hasArea

Returns the maximum point of the box.
-
getBounds
public double[] getBounds()
Gets the corners of the box.
-
intersect
public boolean intersect(SbVec2d pt)
Returns true if the specified point intersects this box.
-
intersection
public SbBox2d intersection(SbBox2d box)
Returns the intersection of the specified box with this box. Returned box is empty if there is no intersection.
-
