Constructor Details

BaseCylinder

protected BaseCylinder()

Construct a default cylinder.

BaseCylinder

protected BaseCylinder(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

hasLocalColors

public boolean hasLocalColors()

Specified whether this node has color information. If so, then it will be used for diffuse terms instead of materials.

Specified by:

hasLocalColors in interface VRMLGeometryNodeType

Returns:

true Use local color information for diffuse lighting.

hasLocalColorAlpha

public boolean hasLocalColorAlpha()

Specified whether this node has alpha values in the local colour information. If so, then it will be used for to override the material's transparency value.

Specified by:

hasLocalColorAlpha in interface VRMLGeometryNodeType

Returns:

true when the local color value has inbuilt alpha

addLocalColorsListener

public void addLocalColorsListener(LocalColorsListener l)

Add a listener for local color changes. Nulls and duplicates will be ignored.

Specified by:

addLocalColorsListener in interface VRMLGeometryNodeType

Parameters:

l - The listener.

removeLocalColorsListener

public void removeLocalColorsListener(LocalColorsListener l)

Remove a listener for local color changes. Nulls will be ignored.

Specified by:

removeLocalColorsListener in interface VRMLGeometryNodeType

Parameters:

l - The listener.

addTexCoordGenModeChanged

public void addTexCoordGenModeChanged(TexCoordGenModeListener l)

Add a listener for texture coordinate generation mode changes. Nulls and duplicates will be ignored.

Specified by:

addTexCoordGenModeChanged in interface VRMLGeometryNodeType

Parameters:

l - The listener.

removeTexCoordGenModeChanged

public void removeTexCoordGenModeChanged(TexCoordGenModeListener l)

Remove a listener for texture coordinate generation mode changes. Nulls will be ignored.

Specified by:

removeTexCoordGenModeChanged in interface VRMLGeometryNodeType

Parameters:

l - The listener.

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

Parameters:

setNum - The set which this tex gen mode refers

Returns:

The mode or NULL

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

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

Returns:

the number of texture coordinate sets

Get the value of the solid field.

Specified by:

isSolid in interface VRMLGeometryNodeType

Returns:

true This object is solid (ie single sided)

isCCW

public boolean isCCW()

Get the value of the CCW field. If the node does not have one, this will return true.

Specified by:
