I don't know about Display.ShapeAngle, but here is an example of how I
rotate a VisADGeometryArray ("shape" in this example). It uses stuff
from Java3D's javax.vecmath package.
Vector3f v
null;
float[] t = new
float[3];
Matrix3f matrix = new Matrix3f();
matrix.rotZ( angle );
for( int i=0; i<shape.coordinates.length; i+=3 ) {
v = new Vector3f( shape.coordinates[i],
shape.coordinates[i+1],
shape.coordinates[i+2] );
matrix.transform(v);
v.get(t);
shape.coordinates[i] = t[0];
shape.coordinates[i+1] = t[1];
shape.coordinates[i+2] = t[2];
}
Hope this helps,
Doug
