on #2 I'll say smaller textures take less memory
though there are different types of memory:
main memory & memory used by the graphics card /
hardware accelerator so it can be system dependent
including what type OS, renderer ( OpenGL vs DirectX )
and graphics hardware.
I'd suggest asking the questions serpartely and
to the appropriate forms.

Sorry for asking this dump question but could you point me to where I

I really appreciate your help.

I'm running Red Hat 7.3 on an Intel Chip,
you need a version of OpenGL, I'm using Mesa3d,
and you need the Java 2 / 1.2+ and the Java3d
from Blackdown.org ( details below ).

From: Juergen Kreileder <j...@BLACKDOWN.DE>
Organization: Blackdown Java-Linux Team
Subject: [ANNOUNCE] Java3D 1.3 for Linux/i386
The Blackdown Java-Linux Team is happy to announce the availability of
Java3D 1.3 for Linux on i386:
The Java 3D API enables the creation of three-dimensional graphics
applications and Internet-based 3D applets. It provides high-level
constructs for creating and manipulation of 3D geometry and building the
structures used in rendering that geometry. With this software, you can
efficiently define and render very large virtual worlds.
Requirements and installation instructions can be found at
http://www.blackdown.org/java-linux/java2-status/README-3D13
Please choose one of our FTP mirrors
(http://www.blackdown.org/java-linux/mirrors.html) for downloading.
Documentation for the Java3D 1.3 API can be downloaded from
http://java.sun.com/products/java-media/3D/download.html

Your KnowledgeBoard sounds like a good "Web Friendly"
soltion that doesn't make "Unfriendly" demands like
requiring people use software from the Monopolist
or as SAIC points out, dangerous & risky schemes:

True, but total misleading here.
Shrek, Pixar etc. do rendering on Linux, the use for 3D rendering like
it is done with VRML, java3D, OpenGL, directX is different.
Didn't you understood the difference between "realtime" 3D rendering
(hopefully) on the graphicscard and offline "movie" rendering on the
processors of a "rendering Farm" (multiple computers, each render
one picture of the movie on the processor in minutes or hours) ?
Of course, building a movie requires also "realtime" 3D rendering
while working with a 3D modeller/animation tool.
Despite some of the expensive movie creation tools like maya or
SideFX houdini have been ported to Linux, information about their usage
as Modellers on Linux in the movie industry is meager 8-(
It is not uncommon, to use different computer systems for modelling
and offline rendering.
Pixar used for years SGI IRIX machines for modelling and a big cluster
of SUN machines for offline rendering.
In earlier days, there were example of render farms made of a room of
Amiga 2000 homecomputers...
