That blending method is one commonly used for particle systems and has a
multiplicative effect on any alphas which are blended. That's probably not
the one that you want. I think the default created by new
TransparancyAttributes() is the one you want.

Subject: [JAVA3D] Too Bright?
Hello,
Does anyone know a solution or workaround for the problem where obscured
transparent objects appear much too bright?
I'm displaying stereo images for viewing with 3D glasses. I use the
following
appearance code:
ap2.setMaterial(new Material(red, black, red, black, 1.0f));
float transparencyValue = 0.5f;
TransparencyAttributes t_attr =
new TransparencyAttributes(
TransparencyAttributes.BLENDED,
transparencyValue,
TransparencyAttributes.BLEND_SRC_ALPHA,
TransparencyAttributes.BLEND_ONE);
ap2.setTransparencyAttributes( t_attr );
ap2.setRenderingAttributes( new RenderingAttributes() );
This works fairly well for simple shapes like I used in
http://www.fungames.org/Pyramid.html
but more complex objects look odd because the parts of the object at the
back
are much too bright,
for example, at http://www.java3d.org/redgreengirl the girl's pony tail is
much
brighter when viewed from the
front (through her head) than when it is viewed from the side.
Any idea what is going on?
From,
Greg
