Hi,
I have a problem with picking and zooming.
In my scene I can pick each object without problem,
but when I am getting closer to the scene (with
MouseZoom), I arrive at a certain limit and picking
no longer recognizes any object. If I move away,
picking works again.
Any suggestions on how to
I'm curious why you want to develop a ray tracer yourself? There are plenty
of superb freeware raytracers available, and they would be much faster than
anything Java could do.
If you need Java to develop a scene you could write an application which
would output a scene description file that could
Pete,
then how do you load ArcInfo binaries into Java3D? I think going to j3d was
the initial problem.

hi Peter,
the up vectoe in lookAt() just describes the up direction of the viewer. If
your viewing direction is parallel to the xz pane the up vector is (0,1,0).
In general the up vector should be perpeticular to the viewing vector.

Have you seen if the option in the Java Plug-in Control Panel (located
in the Start/Programs Menu) to enable the plug-in window is selected ?
Normally when the plugi-in is updated this option is disabled.

Where can I find a list of the image formats that the TextureLoader
class can handle. I specifically need a format that can handle
transparency. I have tried PNG and TIF, but neither seems to be
supported. Until now I have used GIF and JPEG, but neither of them
supports transparency. So which imag

an update of plug-in ), and Java1.2 applet runs correctly except for Java3D
aplications ( there are some problems with Canvas3D ).

Vineet,
I too had the same problem and I got a fix for this
problem. Reinstalling JDK1.3/JRE1.3 and then reinstall
plug in should fix this. I don't know why but it's the
combination of installations that made it work.

where v1 has the same
Hi Peter,
take a look to the API Specs, C 11.2 ff. You have to put the transform3d
created by lookAt() into your view object. Use setVpcTo Ec() of View.
This is because the eye position is not the same as the position of your
viewpoint.

You can subclass it, override the appropriate method, put a try-catch

Hi,
This question is related to the question I asked a few days ago regarding
making a component pop-up after an animation completes. I made a counter
class with two counters in it, one for counting the calls to
Interpolator.processStimulus() and one for counting the calls to
Canvas3D.postSwap().

Project the base of the picking ray back a bit. Just look at the vector
pointing in the same direction as the ray, negate it, multiply by a fudge
factor, and add it
Hi,
Does anyone know what is the fastest way to figure out where a point in
3-D gets mapped (in pixel location) on the screen (relative to the
Canvas3D)? I don't like to use image plate coordinates because they are
based on the whole screen, so you also have to track the coordinates of
the Canvas
hi,
it seems, that invoking 'invert()' after 'lookAt()' makes the view (the ego in the
shooter) look in the
right direction !

Per,
GIF files do support transparency, and I've loaded them into Java 3D and
mapped them onto transparent objects... in fact, I even use Paint Shop Pro!
In PSP you can set the GIF file transparent color by selecting Options in
the Save dialog.
I believe the other format people often use (not u

Jimmy,
A simpler (cleaner) way that might work for you is to derive a class from
Alpha. Override the value() method and watch for the values that your Alpha
is returning. The time/value will tell you when a cycle of the Interpolator
is complete, then it is time to activate your "end of animation"
Hi,
I am trying to work with Java3D and Swing on Linux. I was able to

When I run my program I could see my Canvas3D objects very well,

As daniel explains,
gif can handle transparency !!
In paint shop pro define a color as the transparent one and use it as
required,
