hello there,is it possible to create effects like bump-mapping, or
cubic environmetalmapping with Java3D ?think it should cause AFAIK
is at least the first feature uncluded in OpenGL1.2 standard and in DirectX
6 or higher..so dou you know if these features exist and how to use
them..

Does anyone have an ellipse class already
that i can use. I need it to use a major and two semiminors for parameters...
Just wondering.

does anyone have the new version?
Can you send it to me?

Why don't you download the Java source code from JavaSoft and use Sun's
AWT implementation?

Hi,
We have been very disappointed with Java3D for three reasons:
1. Performance:
a. Rasters are incredibly slow (one small raster takes 15 ms to render).
b. Cost of Appearance node component is prohibitive.
According to the Java3D team even the smallest Appearance

Certainly not true in retained mode. For me small raster do not affect
framerate at all. I suppos

As requested - hot off the presses! Not exactly the cleanest set of code
currently, but mostly it works. This is a snapshot of my current HD, so
plenty of stuff not in CVS, and probably so undocumented.

Ah sh*t. Didn't mean to do that - darn reply-tos. Appologies to eve
Hi Tina
I am a subscriber to the Java3D mailing list though I dont post to it directly.
Your mail got me interested.
In creating the texture object you are using the format as
Texture.RGBA. This is valid only for images with an alpha channel.
If your image doesnt contain an alpha
Not in the current API, but will be possible in Java 3D 1.3. You can

For Review" link.

Hi every body.
This my question:
Has Java3d development board consider to take this api to be capable to do
Ray tracing render in comming versions?

Thats an interesting question, considering that Java3D is a scenegraph not
just a drawing api. Scenegraphs are more organized, and setup for finding
objects in a scene, and certainly they support pickRay tools as well.
But I personaly think if they do, do it, it should probably be an API, so
that
It seems to me that java3d is very good api for small scenes - with lot
of static data. It does a lot of optimalization behind the back and is
significatly easier to use efficently than opengl/directx. This makes it
perfect tool for things like molecule viewers, some medical imaging,
maybe also sp
One of the features we are considering for Java 3D 1.4 is extensibility.
As a part of that we are looking at defining a rendering device interface.
This may be an avenue for implementing such a renderer.

Problem is that java3d is purely polygon based.
new hardware over the next 2 years will be close in terms of horsepower
to making real-time raytracing possible.
nvidia has already demonstrated a life-game that mostly runs on the GPU.
not directly related to raytracing, but shows what sort of computations
can be done in shaders already.

Hi,
One option I used was to ray trace the scene and use the data to make a
texture on the scene graph objects. Obviously not a pretty solution and it
would likely not stand up to higher framerates, but it can work, particularly
if you have limited areas to trace (like a mirror on the wall). -
