public abstract class BaseTextureCoordinate
extends BaseGeometricPropertyNode
implements VRMLTextureCoordinateNodeType

Common base implementation of a texture coordinate node.

Points are held internally as a flat array of values. The point list returned will always be flat. We do this because renderers like point values as a single flat array. The array returned will always contain exactly the number of points specified.

The effect of this is that point values may be routed out of this node as a flat array of points rather than a 2D array. Receiving nodes should check for this version as well. This implementation will handle being routed either form.

Empty constructor

BaseTextureCoordinate

protected BaseTextureCoordinate(VRMLNodeType node)

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

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not the same type

Method Details

getNumTextureComponents

public int getNumTextureComponents()

Get the number of components defined for this texture type. SHould be one of 2, 3 or 4 for 2D, 3D or time-driven textures. Simple VRML textures only allow 2D texture coordinates to be used.

Specified by:

getNumTextureComponents in interface VRMLTextureCoordinateNodeType

Returns:

one of 2, 3 or 4

getNumSets

public int getNumSets()

Get the number of texture coordinate sets contained by this node

Specified by:

getNumSets in interface VRMLTextureCoordinateNodeType

Returns:

the number of texture coordinate sets

getSize

public int getSize(int setNum)

Get the size of the specified set

Specified by:

getSize in interface VRMLTextureCoordinateNodeType

Parameters:

setNum - The set to size

Returns:

setPoint

public void setPoint(int setNum,
 float[] newPoint,
 int numValid)

Accessor method to set a new value for field attribute point. Attempts to set nodes > numSets will throw an exception.

Specified by:

setPoint in interface VRMLTextureCoordinateNodeType

Parameters:

setNum - The set which this point belongs.

newPoint - New value for the point field

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

Throws:

ArrayIndexOutOfBoundsException

getPoint

public void getPoint(int setNum,
 float[] point)

Accessor method to get current value of field point. Sets outside the numSize will throw an exception.

Specified by:

getPoint in interface VRMLTextureCoordinateNodeType

Parameters:

setNum - The set which this point belongs.

point - The current value of point

Throws:

ArrayIndexOutOfBoundsException

isShared

public int isShared(int index)

Determine if this index is shared via DEF/USE inside this set

Specified by:

Parameters:

index - The index to check

Returns:

The index if not shared or the original index DEFed

getTexCoordGenMode

public String getTexCoordGenMode(int setNum)

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

Returns:

A representation of this field's information

getNumFields

public int getNumFields()

Get the number of fields.
