<h2><b>3D Viewing Format<br>
</b></h2>
Gamut and other 3D output visualisations can be created in one of 3
formats:<br>
<br>
<b>VRML</b><br>
A legacy web 3D file format, using the <b>.wrl</b>
file extension.<br>
Either a standalone viewer of a web browser
plugin is needed to view the file.<br>
<br>
<b>X3D</b><br>
A current web 3D file format modeled after VRML,
using the <b>.x3d</b> file extension.<br>
Either a standalone viewer of a web browser
plugin is needed to view the file.<br>
<br>
<b>X3DOM</b><br>
An HTML file using a javascript viewer and an X3D
scene, using the <b>.x3d.html</b> file extension.<br>
Any web browser supporting javascript and WebGL
can be used to display this.<br>
<br>
By default ArgyllCMS tools will output VRML format, but the defaul
can be overridden by setting the environment variable<br>
<b>"ARGYLL_3D_DISP_FORMAT"</b> to <b>"VRML"</b>, <b>"X3D"</b> or <b>"X3DOM"</b><br>
<br>
Note that the X3DOM file has references to the x3dom.css and
x3dom.js support files in the same directory as the created
.x3d.html file, and the tools will create a copy of these files in
that directory if they don't exist. These two files must be copied
with the .x3d.html if it is moved somewhere else.<br>
<br>
To check if your browser supports X3DOM, try <a
href="http://www.x3dom.org/check/">this test page</a>.<br>
<br>
X3DOM navigation in Web browser:<br>
<p>"Examine" - default viewing mode, which can be<br>
re-activate this mode by pressing the "e" key.</p>
