In javascript you need Math.sin instead of sin, Math.sqrt instead of sqrt etc.
Most things would could be done with
http://www.web3d.org/x3d/specificat...html#SFRotation
if the VRML97 standard would define what are the arguments of "multiply"
(which rotation is first, which is second), different browsers handle
this differently 8-(

| Thanks a lot.
Quaternion link is good
I cannot download flames.wrl, I see it.
There is a text version available, or a commented version?
Think that It use animated flat box textured ?
How can I render schowave, torus with animated scaling, with texture or
color white with transparency?
That's for fun but there is models of plane "Super sylph" and "FRX99 version
of Yukikaze" available ?
Aircraft carier too?

The files are also part of the white_dune source distribution:

Strange, this is a "text version".

It use one textured face in a billboard. Maybe it is a not so good idea to
use 0 0 0 as billboard axis 8-(

| The click is generated when IE or explorer opens a window.
You can disable this in:
My Computer>Control Panel>Sounds and Audio Devices>Windows
Explorer>Start Navigation
Windows Explorer and IE and practically the same program and share many
common settings.
There is a balistics velocity scripting example in the library section

| Thank you. Your link is very interesting
Do you know links about Inverse kinetics in robotic?
I want to simulate a 3 axes robot (2 rotate in plane X,Z the last is in Z
[move up down])
How to know witch rotation make the axes 1 &2 to position the tool center to
the wanted, X,Z coordinate ?
