Constructor Detail

TriangleArray

public TriangleArray()

Constructs a TriangleArray with default values.

Method Detail

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

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

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

setEdgeFlags

public void setEdgeFlags(java.nio.ByteBuffer flags)
                  throws java.lang.IllegalArgumentException,
                         InvalidWriteTimingException

Set the edge flag reference to the new array. The number of valid items is taken to be the length of the array (there's only one flag per edge). This replaces the existing edge flag array reference with the new reference. If set to null, will clear the use of edge flags.

In a live scene graph, can only be called during the data changed callback.

Parameters:

flags - The new array reference to use for edge flag information

Throws:

InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener data changed callback method

java.lang.IllegalArgumentException

compareTo

public int compareTo(TriangleArray 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(TriangleArray 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
