IndexedTriangleArray
public IndexedTriangleArray()
- Constructs a TriangleArray with default values.
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 segmentend
- The end point of the segmentfindAny
- 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 polygondataOut
- An array to put the data in for the intersection. Exact
format is described by the flagsdataOutFlags
- 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 raydirection
- The direction vector of the rayfindAny
- 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 polygondataOut
- An array to put the data in for the intersection. Exact
format is described by the flagsdataOutFlags
- 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.
- Parameters:
o
- The object to be compared
- Returns:
- True if these represent the same values
compareTo
public int compareTo(IndexedTriangleArray 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(IndexedTriangleArray 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
