Hi all,
I'm using the openGL version of java1.2.1_03 and I cannot get the
size of my points in a pointarray to change size. I'm using the
pointAttributes class and the setPointSize(float size) method but when I
create my shape3D, the point is always the default size. Is this a bug in
java3d? I checked the bug listings but couldn't find anything. Here's a
sample of my code...
public Shape3D buildParticle() {
/*** Set up the geometry of the rain drop ***/
PointArray point = new PointArray(1, PointArray.COORDINATES);
point.setCoordinate(0, particle.getPosition()); /** position is 0,0,0
**/
/*** Set up the appearance of the rain drop ***/
Appearance appear = new Appearance();
appear.setCapability(appear.ALLOW_POINT_ATTRIBUTES_READ);
appear.setCapability(appear.ALLOW_POINT_ATTRIBUTES_WRITE);
PointAttributes pa = new PointAttributes();
pa.setPointSize((float)particle.getSize());
appear.setPointAttributes(pa);
Shape3D particle_shape = new Shape3D(point, appear);
return particle_shape;
}
