Dear All,
I am still miffed at why I cannot modify the Appearance of the
utils.geometry Sphere class during execution. The CREATE SPHERES section
below shows my basic arrangement for creating a number of Spheres and
setting all capabilities to read and write. The MODIFY COLOUR section is the
method I use to modify the Appearance objects during execution. I keep
getting a
javax.media.j3d.CapabilityNotSetException: Shape3D: no capability to
set appearance
at javax.media.j3d.Shape3D.setAppearance(Compiled Code)
at com.sun.j3d.utils.geometry.Sphere.setAppearance(Compiled Code)
at appearance.ColourSchemeManager.process(Compiled Code)
at
appearance.AppearanceManager.setColourScheme(AppearanceManager.java:7
exception when calling the MODIFY COLOUR part of the code. Strangely enouogh
if I use the COLORCUBE subclass of SHAPE3D then it all works fine. Is this
somethng to do with Sphere's superclass being PRIMITIVE???
Any help REALLY appreciated.
Cheers,
Allistair Crossley
CREATE SPHERES CODE
----------------------------------------
{
Atom[] atoms = m.getAtoms();
boolean renderHeteroAtoms = dOptions.isHeteroAtomsOn();
TransformGroup aTG = new TransformGroup();
aTG.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
aTG.setCapability(Group.ALLOW_CHILDREN_READ);
for(int i = 0; i < atoms.length; i++)
{
if( (!renderHeteroAtoms) && (atoms[i].isHetatm()) )
continue;
Transform3D atomT3D = new Transform3D();
atomT3D.set(0.1, new Vector3d(atoms[i].getX(), atoms[i].getY(),
atoms[i].getZ()));

file://atomTG.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
atomTG.setCapability(Group.ALLOW_CHILDREN_READ);

Appearance app = new Appearance();
Sphere atom = new Sphere(5.0f, app);
file://Sphere s = new Sphere(
(ElementsManager.getElement(atoms[i].getRefNo()).getVDWRadius()) / 20, 1,
app);
file://Shape3D atom = s.getShape();
atom.setCapability(Group.ALLOW_CHILDREN_READ);

return aTG;

MODIFY COLOUR CODE
-------------------------------------
this.molecule = m;
Atom[] a = molecule.getAtoms();
Bond[] bonds = molecule.getBonds();
TransformGroup theAtoms;
int numAtomChildren;
switch(mode)
{
case DisplayModeManager.SPACEFILL :
int numChildren = atomsTG.numChildren();
for(int i = 0; i < numChildren; i++)
{
TransformGroup atomTG = (TransformGroup)atomsTG.getChild(i);
Sphere atom = (Sphere)atomTG.getChild(0);
switch(s)
{
case AMINO : atom.setAppearance(getAmino(a[i],
DisplayModeManager.SPACEFILL, false));
break;
case CHAIN : atom.setAppearance(getChain(a[i].getChain(),
a[i].isHetatm(), DisplayModeManager.SPACEFILL, false));
break;
case CPK : atom.setAppearance(getCPK(a[i],
DisplayModeManager.SPACEFILL, false));
break;
}
}
break;
