I want to change the color in coloringattributes of shape, which is part
of a life scenegraph...
I set the capabilities of appearance, coloringattributes and shape
accordingly:
shape.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
shape.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
colattr.setCapability(ColoringAttributes.ALLOW_COLOR_READ);
colattr.setCapability(ColoringAttributes.ALLOW_COLOR_WRITE);
and...
app.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_READ);
app.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_WRITE);
Appearance app = shape.getAppearance();
ColoringAttributes colattr = app.getColoringAttributes();
Color3f color = new Color3f();
colattr.getColor(color);
JColorChooser cc = new JColorChooser();
Color newcol = cc.showDialog(this, "Choose Color", new Color(color.x,
color.y, color.z));
float r = newcol.getRed()/256f;
float g = newcol.getGreen()/256f;
float b = newcol.getBlue()/256f;
colattr.setColor(new Color3f(r, g, b));
app.setColoringAttributes(colattr);
shape.setAppearance(app);
but the code does not yield the desired result...
can someone give me a hint? (I already compared the references of the
shape-instance... it is the same at any
time during execution of the app)
so I have to call a kind of refresh-routine for the scenegraph after
modifying the color?
