None standard extensions for the standard VRML97 nodes in Cover/Covise
(the line with ... reminds to the standard fields of this node):<br>
<ul>
<li><a name="Appearance"></a><b>Appearance</b><br>
<pre>
Appearance {
...
exposedField SFNode texture2 NULL
exposedField SFNode textureTransform2 NULL
exposedField SFNode texture3 NULL
exposedField SFNode textureTransform3 NULL
exposedField SFNode texture4 NULL
exposedField SFNode textureTransform4 NULL
}
</pre>
The texture2/texture3/texture4 fields are similar to the texture
field of the standard VRML97 Appearance node. They can be used
for multitexturing with texture nodes like ImageTexture, PixelTexture,
MovieTexture or the none standard Cover/Covise CubeTexture node.<br>
<br>
The textureTransform2/textureTransform3/textureTransform4 fields are
similar to the textureTransform field of the standard VRML97 Appearance
node. The data of textureTransform2 is applied to texture2, the
data of textureTransform3 is applied to texture3, the
data of textureTransform4 is applied to texture4.
</li>
<li><a name="ImageTexture"></a><b>ImageTexture</b><br>
<pre>
ImageTexture {
...
field SFBool environment false
field SFInt32 blendMode 0 # (0,5)
field SFInt32 filterMode 0 # (0,5)
field SFInt32 anisotropy 1 # (0,2)
}
</pre>
The <a name="blendMode"></a>blendMode field is important for
multitexturing. Each number stands
for the function the texture is mixed with other textures of a multitextured
node.<br>
The meaning of the numbers are:<br>
<ul>
<li>
1: Modulate
</li>
<li>
2: Blend
</li>
<li>
3: Decal
</li>
<li>
4: Replace
</li>
<li>
5: Add
</li>
</ul>
The number 0 means to use the default, which is set in the covise/cover
configuration files.<br>
<br>
The filterMode field is used for texture filtering.
The meaning of the numbers are:<br>
<ul>
<li>
1: LINEAR
</li>
<li>
2: LINEAR_MIPMAP_LINEAR
</li>
<li>
3:LINEAR_MIPMAP_NEAREST
</li>
<li>
4:LINEAR_MIPMAP_LINEAR
</li>
<li>
5:NEAREST
</li>
</ul>
The number 0 means to use the default, which is set in the covise/cover
configuration files.<br>
<br>
The anisotropy field is used for anisotropic texture filtering.
The meaning of the numbers are:<br>
<ul>
<li>
1: anisotropisches Filtering
</li>
<li>
2: GL_EXT_texture_filter_anisotropic
</li>
</ul>
The number 0 means to use the default, which is set in the covise/cover
configuration files.<br>
</li>
<li><a name="IndexedFaceSet"></a><b>IndexedFaceSet</b><br>
<pre>
IndexedFaceSet {
...
exposedField SFNode texCoord2 NULL
exposedField SFNode texCoord3 NULL
exposedField SFNode texCoord4 NULL
}
</pre>
The texCoord2/texCoord3/texCoord4 fields are similar to the texCoord
field of the standard VRML97 IndexedFaceSet node. They can be used
for multitexturing with TextureCoordinate nodes.<br>
</li>
<li><a name="MovieTexture"></a><b>MovieTexture</b><br>
<pre>
MovieTexture {
...
field SFInt32 blendMode 0 # (0,5)
}
</pre>
The blendMode field of the MovieTexture node is similar to the
<a href="#blendMode">blendMode field of ImageTexture</a>
</li>
<li><a name="NavigationInfo"></a><b>NavigationInfo</b><br>
<pre>
NavigationInfo {
...
eventIn SFBool set_bindLast
exposedField SFFloat scale -1
}
</pre>
The set_bindLast eventIn is used for returning to the last status
of the node as the node was active.<br>
The scale field is used to redefine the units of the world.<br>
In Cover/Covise, the units of the world are per default different from the
1 unit/1 Meter recommendation in the ISO 14772. Instead, Cover/Covise use
a 1 unit/1 millimeter default. Cause size is especially important in
immersive virtual reality, Cover/Covise has the nonstandard field scale
for easy integration of usual sized worlds.
</li>
<li><a name="PixelTexture"></a><b>PixelTexture</b><br>
<pre>
PixelTexture {
...
field SFInt32 blendMode 0 # (0,5)
}
</pre>
The blendMode field of the PixelTexture node is similar to the
<a href="#blendMode">blendMode field of ImageTexture</a>
</li>
<li><a name="Shape"></a><b>Shape</b><br>
<pre>
Shape {
...
field SFNode effect NULL
}
</pre>
The effect field is intended to be used by shader based geometry
modificators. Currently the only valid nodetype allowed for the
effect field is the now deprecated Wave node.
</li>
<li><a name="Transform"></a><b>Transform</b><br>
<pre>
Transform {
...
... scale ... # [-infinite, infinite]
}
</pre>
The only difference between the standard fields of the Transform node
and the Covise/Cover extension is the range of allowed values of the
scale field. In standard VRML97 the range is [0, infinite] which means
that only positive scale values are allowed. The Covise/Cover extension
also allows negative values. If a negative value occures in the x, y or
z axis, the children content of the Tranform node is mirrored in the
matching direction.
</li>
<li><a name="Viewpoint"></a><b>Viewpoint</b><br>
<pre>
Viewpoint {
...
eventIn SFBool set_bindLast
exposedField SFString type "" # "" "HORIZONTAL"
}
</pre>
The set_bindLast eventIn is used for returning to the last status
of the node as the node was active.<br>
If the type field is set to the value "HORIZONTAL", rolling movements
of the viewpoints are avoided. This is usefull, because rolling movements
of the viewpoint can be cause motion sickness in immersive virtual reality
systems.
</li>
<li><a name="WorldInfo"></a><b>WorldInfo</b><br>
<pre>
WorldInfo {
...
field SFBool correctBackFaceCulling TRUE
field SFBool correctSpatializedAudio TRUE
}
</pre>
</li>

eventOut SFVec3f avatar1Position
eventOut SFRotation avatar1Orientation
eventOut SFVec3f localPosition

exposedField SFInt32 soundEnvironment 26
}
</pre>
The fields localPosition and localOrientation act like a ProximitySensor,
but unlike a ProximitySensor it deliver the data of the tracking system,
not the data of the virtual camera: turning the head in a CAVE do not
change the Proximitity data but change the localPosition/localOrientation
data<br>
<br>
The fields position1 - position8 and orientation1 - orientation8 are
related to some covise plugins they are "not important"<br>
<br>
The meaning of the other fields are not known yet

exposedField MFString urlYN ""
exposedField MFString urlZP ""
exposedField MFString urlZN ""
exposedField SFBool repeatS TRUE
exposedField SFBool repeatT TRUE
exposedField SFInt32 blendMode 0
}
</pre>
The COVER CubeTexture node implements environment mapping
("fake realtime mirror").
Mirror images are simples mapped as Texture to a object.
If the object rotates, the Texture on the object rotate accordingly.<br>
<br>
The urlXP, urlXN etc. urls similar to the texture fields in the
VRML97 Background node
