I'm running into something curious, I'm creating a PointArray and placing it
in a Shape object. Then I apply PointAttributes setting the point size and
antiailasing. If antiailiasing is off, the points displayed are the correct
size. But when I turn antiailiasing on, the points drop down to a point size
of 1 even though they're set to say... 10.
This is on a Windows NT 4.0 (service pack 4) workstation with a Intense3D
Wildcat 3510 graphics card.
Now on my old workstation with a generic "crappy" graphics card things seem
to work just fine.
In another program using a PointArray like above, if I turn on antiailasing,
no points show up at all. I've searched through both codes and can't find
anything different between the two in how the Shape is set up, yet they
don't behave the same way. This second program does use MathEngine to
generate and move the Point3d coordinates, but not to display anything. Is
it possible that this makes a difference?
How can I tell if I've installed J3D with DirectX or OpenGL (I don't
remember), and does this make a difference?
I have other appearance problems on the Wildcat workstation as well, weird
effects when displaying surfaces with materials and specular lighting
etc....
Is the Wildcat Card the problem, or possibly DirectX or OpenGL?
