<h3>1.4 Committed Features<br>
</h3>
<p>This list of high priority features will almost certainly make
it
into the 1.4 version of the Java 3D API.</p>
<ul>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/shaders.html">Programmable
Shaders</a></li>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/graph-change-listener.html">Scene
graph structure change
listeners</a></li>
<li><a
href="http://javadesktop.org/java3d/javadoc/1.4.0-latest/javax/media/j3d/SceneGraphObject.html#setName%28java.lang.String%29">Name
string</a> for all scene graph objects: add public <a
href="http://javadesktop.org/java3d/javadoc/1.4.0-latest/javax/media/j3d/SceneGraphObject.html#setName%28java.lang.String%29"><code>get/setName(String)</code></a>
to <code>SceneGraphObject</code>
class</li>
<li>New <a
href="http://javadesktop.org/java3d/javadoc/1.4.0-latest/javax/media/j3d/Node.html#ALLOW_PARENT_READ"><code>ALLOW_PARENT_READ</code></a>
capability bit in <code>Node</code>
class that will allow <a
href="http://javadesktop.org/java3d/javadoc/1.4.0-latest/javax/media/j3d/Node.html#getParent%28%29"><code>getParent()</code></a>
to be called on live/compiled scene graph</li>
<li>Ability to get the locale from a live node: add public <code>getLocale()</code>
method and <code>ALLOW_LOCALE_READ</code> capability bit to <code>Node</code>
class<br>
</li>
<li>Additional blending functions, for example: <code>BLEND_SRC_COLOR</code>,
<code>BLEND_ONE_MINUS_SRC_COLOR</code>, <code>BLEND_DST_COLOR</code>,
<code>BLEND_ONE_MINUS_DST_COLOR</code>, etc.</li>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/picking.html">Additional
core picking methods</a> (in
Locale and BranchGroup)</li>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/stencil.html">Stencil
buffer</a><br>
</li>
</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>

<h3>Other Features for 1.4, 1.5, ...<br>
</h3>
<p>This list of medium priority features is under discussion for
possible inclusion
into the 1.4 or 1.5 API (or beyond). </p>
<ul>
<li>Non-power-of-two textures</li>
<li>Point sprites</li>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/vsg-op.html">Ability
for nested ViewSpecificGroup nodes
to replace the set of views</a><br>
</li>
<li>API support for retained alpha buffers</li>
<li>Ability to query properties from a <code>GraphicsConfiguration</code></li>
<li>Better support for off-screen configuration parameters
(e.g., an
attribute in <code>GraphicsConfigTemplate3D</code> indicating whether
the requested <code>GraphicsConfiguration</code> is used for on-screen
rendering,
off-screen rendering, or both)</li>
<li>Enhance <code>getLocalToVWorld()</code> to return a valid
result
for non-live graphs.</li>
<li><a
href="file:///home/kcr/java3d/1.3.3/j3d-core/www/j3d1_4/lightweight-canvas3d.html">Lightweight
Canvas3D (e.g.,
JCanvas3D)</a>. <span style="color: rgb(204, 0, 0);">Note: this
feature
will not
happen
without an someone from the community volunteering
to drive it.</span></li>
<li>Add a new attribute for depth test function to
RenderingAttributes: public <code>get/setDepthTestFunction(int function)</code>
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 would be <code>LESS_OR_EQUAL</code> for backward
compatibility. <span style="color: rgb(204, 0, 0);">Note: this feature
will not
happen
without an someone from the community volunteering
to drive it.</span></li>
<li>Method to retrieve the geometry data from the tessellation
of a
glyph in a 3D font: a
public <code>GeometryArray getGlyphGeometry(</code><code>int glyphCode</code><code>)</code>
method in the <code>Font3D</code> class. <span
style="color: rgb(204, 0, 0);">Note: this feature will not
happen
without an someone from the community volunteering
to drive it.</span><span style="color: rgb(204, 0, 0);"></span></li>
<li>Additional texture formats:
<ul>
<li>NIO buffer support</li>
<li>Texture compression formats</li>
</ul>
</li>

<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>
