[ Java3D API DOC ]
Data in any array that is referenced by a live or compiled GeometryArray
object may ONLY be modified via the updateData method (subject to the
ALLOW_REF_DATA_WRITE capability bit). Applications must exercise care not to
violate this rule. If any referenced geometry data is modified outside of the
updateData method, the results are undefined.
[/ Java3D API DOC ]
one of my problems was that with the upadateDate(Geometry) method i only have
access to the GeometryArray, but often i need more data for updating, in the
follwing case weights and transformIndices for every vertex. so i'VE done a
quick code abstract, to which i have two questions:
- is this code right, and save for future Java3D version and plattforms ?
- is there a more efficient/flexible way to achive the same results ?
the code goes here:
---------------------------------------
---------------------------------------
public interface MeshUpdater extends javax.media.j3d.GeometryUpdater
{
void updateData(Mesh mesh);
}
---------------------------------------
public class Mesh
{
GeometryArray geometryArray;
float[][] weights;
int[][] transformIndices;
public Mesh(){}
public void updateData(MeshUpdater meshUpdater)
{
meshUpdater.updateData(this);
}
//set and get methods:..
}
---------------------------------------
public class Skeleton implements MeshUpdater
{
Transform3D[] transforms;
//mesh attributs needed for updating
float[][] weights;
int[][] transformIndices;
public Skeleton() {}
public void updateData(Geometry geometry)
{
//now i can use the weights und transformIndices for manipulart..
}
public void updateData(Mesh mesh)
{
weights = mesh.weights;
transformIndices = mesh.transformIndices;
mesh.geometryArray.updateData(this);
}
}
---------------------------------------
