Folks,
The test release for M4 is now available on the web pages of the Web3d
consortium. We'd appreciate some feedback on how well this works - for
example, whether it even installs, or installs, but can't run stuff etc.
We'd like to avoid any stupid errors like we had last time with the

There are several problem in your test program:

Thank you for your valuable suggestions.
I am using OpenGL version. Yes, I did set the

I realise there's been a lot of talk about flickering displays but this

I think I may have found a bug in Java3D 1.3 beta1.
I've attached a small program that adds points to a LineStripArray to
make it form a circular path. When it adds a new point, it increments
the line's visible length by calling setStripVertexCounts(). It also
sets the color of the vertex to a f

Ok, some math following:
we'll start with a simplified case, mapping a line to a circle in 2D space.
suppose we have a line given by a point o_ and a directlional vector y_
which we conveniently normailse to have a length of 1: |y_|=1. The equation
for the line is then
x1_ = o_ + a * y_. (1)

Well I tryed to run my j3d app on SGI (IRIX 6.5, j3d 1.2, don't know the type of

Hi,
Did you set the driver option
Display Properties->GeForce2->Additional Properties
->OpenGL Setting->Vertical sync
to On ? (by default it is Off).
Also, there is no need to have 2 swap(), one
is good enough at the end for both left and right eye.
Thanks.

Good design often separates data from implementation
code and loading 3d models as VRML datafiles into
a modern, efficient language like Java3d gives you
a portable, efficient, network friendly solution.

Looks like the geometry array was built without a COLORS_3 or COLOR_4 flag.
That would mean that the geometry array cannot have its colors set. If you
