public class Skew
extends TransformNode

Skew defines a Collada skewing transform, specified in "Renderman" style. It is defined by a translation vector (vertices are shifted parallel to this vector), and a rotated vector plus rotation angle. The skewing operation should have the effect of rotating this latter vector, in the direction as denoted by the tranlation vector. The angle is specified in degrees. The Renderman/Collada specification is by means of a seven-tuple: angle, rotated vector, translation vector.

     throws IOException

Throws:

IOException

Method Detail

getMat4f

public float[] getMat4f()

Returns the 4X4 skewing matrix, according to the Renderman specification, in row-major order.

Overrides:

getMat4f in class TransformNode

getSkewMat3f

public float[] getSkewMat3f()

Returns the 3X3 skewing matrix, according to the Renderman specification, in row-major order.

appendContent

public StringBuilder appendContent(StringBuilder buf,
                                   XMLFormatting fmt)

Description copied from class: XMLStructureAdapter

Appends a String to buf that encodes the contents for the XML encoding. MUST BE OVERWRITTEN BY IMPLEMENTATIONS. (The default implementation appends nothing). The encoding should start on a new line, using indentation equal to tab. There should be no newline after the encoding.

Overrides:

appendContent in class XMLStructureAdapter

decodeContent

public void decodeContent(XMLTokenizer tokenizer)
                   throws IOException

Description copied from class: XMLStructureAdapter

decodes the XML contents, i.e. the XML between the STag and ETag of the encoding. MUST BE OVERWRITTEN BY IMPLEMENTATIONS.

Overrides:

decodeContent in class XMLStructureAdapter

Throws:

IOException

xmlTag

public static String xmlTag()

The XML Stag for XML encoding

getXMLTag

public String getXMLTag()

returns the XML Stag for XML encoding

Specified by:

getXMLTag in interface XMLStructure

Overrides:

getXMLTag in class XMLStructureAdapter
