Java 3D community on java.net (see
<a href="https://java3d.dev.java.net">https://java3d.dev.java.net</a>).
They are already part of daily and periodic stable builds available on
java.net.</p>

<h3><a name="Default_values"></a>2. Default values for read capability
bits<br>
</h3>
<p>Capability bits control whether data in a Java 3D scene graph
object
may be read or written when it is part of a live or compiled subgraph.
We propose to change the default value for all read capability bits to
true, meaning that all attributes may be read by default (the default
value for all write capability bits will remain false, meaning that no
attributes may be written by default). Note that read capability bits
are defined as those capability bits of the form <code>ALLOW_*_READ</code>,
plus the <code>ALLOW_INTERSECT</code> capability bit.<br>
</p>
<code></code>
<p><br>
</p>
<h3><a name="Picking"></a>3. Picking<br>
</h3>
<p>We propose to add a new PickInfo class (with an inner class to hold
intersection information), and new core picking methods that return
objects of this new class type.<br>
</p>
<p>New Classes:<br>
</p>
<ul>
<code><span style="font-weight: bold; text-decoration: underline;"></span>public
class <span style="font-weight: bold;">PickInfo</span> extends Object<br>
public class <span style="font-weight: bold;">PickInfo.IntersectionInfo</span>
extends
Object<br>
</code>
</ul>
<p>New methods:<br>
</p>
<ul>
<code><span style="font-weight: bold; text-decoration: underline;">Locale</span><br>
public PickInfo[] pickAll( int mode, int flags,
PickShape pickShape )<br>
public PickInfo[] pickAllSorted( int mode, int
flags, PickShape pickShape )<br>
public PickInfo pickClosest( int mode, int
flags, PickShape pickShape )<br>
public PickInfo pickAny( int mode, int flags,
PickShape pickShape )<br>
<br>
<br>
<span style="font-weight: bold; text-decoration: underline;">BranchGroup</span><br>
public PickInfo[] pickAll( int mode, int flags,
PickShape pickShape )<br>
public PickInfo[] pickAllSorted( int mode, int
flags, PickShape pickShape )<br>
public PickInfo pickClosest( int mode, int
flags, PickShape pickShape )<br>
public PickInfo pickAny( int mode, int flags,
PickShape pickShape )</code>
</ul>
<p><br>
</p>
<h3><a name="Stencil"></a>4. Stencil<br>
</h3>
<p>We propose new stencil functionality. Here are the proposed new
fields and methods:<br>
</p>

public int getStencilSize()<br>
</code>
</ul>
<p><br>
</p>
<h3><a name="Rendering_attributes"></a>5. Rendering attributes<br>
</h3>
<p>We propose to add new rendering attributes/modes to enable
applications to specify the depth test function, additional raster
operations, and additional blending modes. The new fields and methods
are as follows:<br>
</p>
<ul>
<code> <span style="text-decoration: underline; font-weight: bold;">RenderingAttributes</span><br>

<h3><a name="Other_minor_features"></a>6. Other minor features<br>
</h3>
<p>We propose to add the following new features: a name for all scene
graph objects; the ability to get the Locale or parent from a live or
compiled scene graph, a scene graph structure change listener, and a
method to get the tessellated glyph geometry for a character in a 3D
font.
</p>
<p>The following new class has been added:</p>
<ul>
<code>public interface <span style="font-weight: bold;">GraphStructureChangeListener</span><br>

</ul>
<p>The new fields and methods are as follows:</p>
<ul>
<code> <span style="font-weight: bold; text-decoration: underline;">VirtualUniverse</span><br>
