OpenGL implGeomementation of an Extrusion

The 1.16 version of OGLExtrusion generates end caps correctly for both convex and concave crossSections. More thorough testing is needed to see if textures are handled properly, however.

Constructor Details

OGLExtrusion

public OGLExtrusion()

Construct a default sphere instance

OGLExtrusion

public OGLExtrusion(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not a Box node, an exception will be thrown.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not a Group node

Method Details

updateNodeBoundsChanges

public void updateNodeBoundsChanges(Object src)

Notification that its safe to update the node now with any operations that could potentially effect the node's bounds.

Specified by:

updateNodeBoundsChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

updateNodeDataChanges

public void updateNodeDataChanges(Object src)

Notification that its safe to update the node now with any operations that only change the node's properties, but do not change the bounds.

Specified by:

updateNodeDataChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

getGeometry

public org.j3d.aviatrix3d.Geometry getGeometry()

Returns a OGL Geometry node

Specified by:

getGeometry in interface OGLGeometryNodeType

Returns:

A Geometry node

setTextureCount

public void setTextureCount(int count)

Set the number of textures that were found on the accompanying Appearance node. Used to set the number of texture coordinates that need to be passed in to the renderer when no explicit texture coordinates were given.

Specified by:

setTextureCount in interface VRMLGeometryNodeType

Overrides:

setTextureCount in class BaseExtrusion

Parameters:

count - The number of texture coordinate sets to add

getNumSets

public int getNumSets()

Get the number of texture coordinate sets contained by this node

Specified by:

getNumSets in interface VRMLGeometryNodeType

Overrides:

getNumSets in class BaseExtrusion

Returns:

the number of texture coordinate sets

getTexCoordGenMode

public String getTexCoordGenMode(int setNum)

Get the texture coordinate generation mode. NULL is returned if the texture coordinates are not generated.

Specified by:

getTexCoordGenMode in interface VRMLGeometryNodeType

Overrides:

getTexCoordGenMode in class BaseExtrusion

Parameters:

setNum - The set which this tex gen mode refers

Returns:

The mode or NULL

setValue

public void setValue(int index,
 float[] value,
 int numValid)
              throws InvalidFieldException,
InvalidFieldValueException

Set the value of the field at the given index as an array of floats. This would be used to set MFFloat, SFVec2f, SFVec3f and SFRotation field types.

Specified by:

setValue in interface VRMLNodeType

Overrides:

setValue in class BaseExtrusion

Parameters:

index - The index of destination field to set

value - The new value to use for the node

numValid - The number of valid values to copy from the array

Throws:

InvalidFieldException - The field index is not known

InvalidFieldValueException - The value provided is out of range for the field type.

allEventsComplete

public void allEventsComplete()

Notification that the rendering of the event model is complete and that rendering is about to begin. Used to update the j3d representation only once per frame.

Specified by:

allEventsComplete in interface FrameStateListener

Overrides:

allEventsComplete in class AbstractNode

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the Java3D scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation.

setupFinished

public void setupFinished()

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class AbstractNode
