Constructor Detail

IndexedQuadStripArray

public IndexedQuadStripArray()
Constructs a QuadStripArray with default values.

Method Detail

isVisible

protected boolean isVisible()
Check to see if this geometry is making the geometry visible or not. Returns true if the defined number of coordinates, indices and strips are all non-zero.

Overrides:
isVisible in class IndexedBufferGeometry
Returns:
true when the geometry is visible

pickLineSegment

public boolean pickLineSegment(float[] start,
                               float[] end,
                               boolean findAny,
                               float[] dataOut,
                               int dataOutFlags)
                        throws NotPickableException
Check for all intersections against this geometry using a line segment and return the exact distance away of the closest picking point.

Specified by:
pickLineSegment in interface LeafPickTarget
Overrides:
pickLineSegment in class Geometry
Parameters:
start - The start point of the segment
end - The end point of the segment
findAny - True if it only has to find a single intersection and can exit as soon as it finds the first intersection. False if it must find the closest polygon
dataOut - An array to put the data in for the intersection. Exact format is described by the flags
dataOutFlags - A set of derived-class specific flags describing what data should be included in the output array
Returns:
True if an intersection was found according to the input request
Throws:
NotPickableException - This object has been marked as non pickable, but you decided to try to call the method anyway

pickLineRay

public boolean pickLineRay(float[] origin,
                           float[] direction,
                           boolean findAny,
                           float[] dataOut,
                           int dataOutFlags)
                    throws NotPickableException
Check for all intersections against this geometry using a line ray and return the exact distance away of the closest picking point.

Specified by:
pickLineRay in interface LeafPickTarget
Overrides:
pickLineRay in class Geometry
Parameters:
origin - The start point of the ray
direction - The direction vector of the ray
findAny - True if it only has to find a single intersection and can exit as soon as it finds the first intersection. False if it must find the closest polygon
dataOut - An array to put the data in for the intersection. Exact format is described by the flags
dataOutFlags - A set of derived-class specific flags describing what data should be included in the output array
Returns:
True if an intersection was found according to the input request
Throws:
NotPickableException - This object has been marked as non pickable, but you decided to try to call the method anyway

render

public void render(javax.media.opengl.GL gl)
Issue ogl commands needed for this renderable object.

Parameters:
gl - The gl context to draw with

compareTo

public int compareTo(java.lang.Object o)
              throws java.lang.ClassCastException
Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Parameters:
o - The objec to be compared
Returns:
-1, 0 or 1 depending on order
Throws:
java.lang.ClassCastException - The specified object's type prevents it from being compared to this Object

equals

public boolean equals(java.lang.Object o)
Compare this object for equality to the given object.

Specified by:
equals in interface Renderable
Overrides:
equals in class java.lang.Object
Parameters:
o - The object to be compared
Returns:
True if these represent the same values

setStripCount

public void setStripCount(int[] counts,
                          int num)
                   throws InvalidWriteTimingException
Set the number of valid strips to use. A check is performed to make sure that the number of vertices high enough to support the total of all the strip counts so make sure to call setVertex() with the required array length before calling this method. Each strip must be a minumum length of three.

Parameters:
counts - The array of counts
num - The number of valid items to read from the array
Throws:
java.lang.IllegalArgumentException - Invalid total strip count or individual strip count < 3
InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener bounds changed callback method

getValidStripCount

public int getValidStripCount()
Get the number of valid strips that are defined for this geometry.

Returns:
a positive number

getStripCount

public void getStripCount(int[] values)
Get the sizes of the valid strips. The passed array must be big enough to contain all the strips.

Parameters:
values - An array to copy the strip values into

compareTo

public int compareTo(IndexedQuadStripArray ta)
Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Parameters:
ta - The argument instance to be compared
Returns:
-1, 0 or 1 depending on order

equals

public boolean equals(IndexedQuadStripArray ta)
Compares this object with the specified object to check for equivalence.

Parameters:
ta - The geometry instance to be compared
Returns:
true if the objects represent identical values
