QuadArray
public QuadArray()
- Constructs a QuadArray with default values.
renderState
public void renderState(net.java.games.jogl.GL gl,
net.java.games.jogl.GLU glu)
- Issue ogl commands needed for this renderable object.
- Overrides:
renderState
in class NodeComponent
- Parameters:
gl
- The gl context to draw withglu
- The utility context to draw with
restoreState
public void restoreState(net.java.games.jogl.GL gl,
net.java.games.jogl.GLU glu)
- Restore all openGL state.
- Overrides:
restoreState
in class NodeComponent
- Parameters:
gl
- The gl context to draw withglu
- The utility 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. Default
implementation always returns false indicating that nothing was found.
Derived classes should override and provide a real implementation.
- Overrides:
pickLineSegment
in class VertexGeometry
- 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. Default
implementation always returns false indicating that nothing was found.
Derived classes should override and provide a real implementation.
- Overrides:
pickLineRay
in class VertexGeometry
- 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
