<h3>1.4 Committed Features<br>

capability bit in <code>Node</code>

to be called on live/compiled scene graph</li>
<li>Ability to get the locale from a live node: add public <a
href="http://download.java.net/media/java3d/javadoc/1.4.0-latest/javax/media/j3d/Node.html#getLocale%28%29"><code>getLocale()</code></a>
method and <a

capability bit to <code>Node</code>
class</li>
<li>Add a new attribute for depth test function to
RenderingAttributes: public <a

methods that takes as values one of: <code>ALWAYS, NEVER,
EQUAL, NOT_EQUAL, LESS, LESS_OR_EQUAL, GREATER, GREATER_OR_EQUAL</code>.
The default value is <code>LESS_OR_EQUAL</code> for backward
compatibility.</li>
<li>Method to retrieve the geometry data from the tessellation
of a glyph in a 3D font: a public <a

</ul>
<p>This is a list of features that we propose to <a
href="#Footnote_1">deprecate<sup>1</sup></a> in
the API.<br>
</p>
<ul>
<li><code>CompressedGeometry</code> class (no HW support, lack
of
industry
acceptance)</li>
<li>Sensor prediction (has never been implemented)<br>
</li>
<li><code>PickPoint</code> class (not fully implemented, cannot
be
used for
geometry-based picking; use PickBounds with
a
BoundingSphere that has a small radius)</li>
<li><code></code><code>Morph</code> node (expensive, picking
doesn't
work,
can be done
in a utility)</li>
</ul>

<p><small><a name="Footnote_1"></a>1 – Note that deprecated
features will not actually be removed. It
instead
reflects a decrease of emphasis on these features. While they should
continue
to function normally, no additional effort is likely to be put into
them (for example, compressed geometry will not be supported with
programmable shaders). This action paves the way to remove them from a
future major release (e.g., a 2.0 release).</small></p>
