  hmi.xml.XMLStructureAdapter
      hmi.graphics.scenegraph.VertexWeights

All Implemented Interfaces:

XMLStructure

public class VertexWeights
extends XMLStructureAdapter

A VertexWeight object couples GMesh vertices to one or more joints, with a certain weight. The number of joints associated which a single vertex is variable, and specified with the jcount parameter of the constructor. Joints are referred to by means of joint indices, resolved within the GMesh to actual joint names.

Constructor Detail

VertexWeights

public VertexWeights()

Default constructor

VertexWeights

public VertexWeights(int[] jcount,
                     int[] jointIndices,
                     float[] jointWeights)

Creates a new VertexWeight object: jcounts specifies, for every GMesh vertex, the number of associated joints. The jointIndices array contains the actual joint indices, arranged into small (variable length) segments with lengths specified by the jcount parameter. Each element of a segment refers to a single joint. The jointWeights array has a structure similar to jointIndices. It specifies the weights for the vertex-to-joint links.

Method Detail

calculateOffsets

private int calculateOffsets()

getJointIndices

public int[] getJointIndices()

Returns the jointIndices array.

getJointWeights

public float[] getJointWeights()

Returns the jointWeights array.

getJCounts

public int[] getJCounts()

remapData

protected void remapData(int nrOfDistinctVertices,
                         int[] map)

checkAccumulatedWeights

public boolean checkAccumulatedWeights(float epsmin,
                                       float epsplus,
                                       boolean showdeviations)

getVertexWeightColors

public float[] getVertexWeightColors(boolean useWeights,
                                     float[][] colorCoding)

Returns a float array filled with vertex colors, encoding the vertex weight information.

toString

public String toString()

Description copied from class: XMLStructureAdapter

the default toString() method returns the result of toXMLSTring()

Overrides:

toString in class XMLStructureAdapter

appendAttributeString

public StringBuilder appendAttributeString(StringBuilder buf,
                                           XMLFormatting fmt)

appends the id and sid XML attributes to buf.

Overrides:

appendAttributeString in class XMLStructureAdapter

decodeAttributes

public void decodeAttributes(HashMap<String,String> attrMap,
                             XMLTokenizer tokenizer)

decodes the id and sid XML attributes.

Overrides:

decodeAttributes in class XMLStructureAdapter

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:
