.PP 
The \fBSoTextureUnit\fP class is a node for setting the active texture unit\&. 

When an \fBSoTextureUnit\fP node is inserted into the scene graph, all subsequent texture nodes (\fBSoTexture2\fP, \fBSoTextureCoordinate2\fP, \fBSoTextureCoordinate3\fP, \fBSoTexture2Transform\fP, \fBSoTexture3Transform\fP, \fBSoTextureCoordinateEnvironment\fP, \fBSoTextureCoordinatePlane\fP and \fBSoComplexity\fP) will affect the texture unit set in the unit field\&.

.PP
See the SoGuiExample module for an usage example for this node\&.

This static method returns the \fBSoType\fP object associated with objects of this class\&. 
.br
 
.SS "\fBSoType\fP SoTextureUnit::getTypeId (void ) const\fR [virtual]\fP"
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for runtime type checking and 'downward' casting\&. 
.br
 
.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP ** SoTextureUnit::getFieldDataPtr (void )\fR [static]\fP, \fR [protected]\fP"
\fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP
.br

.br
 Returns the \fBSoFieldData\fP class which holds information about fields in this node\&. 
.br
 
.SS "const \fBSoFieldData\fP * SoTextureUnit::getFieldData (void ) const\fR [protected]\fP, \fR [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fRNULL\fP\&. 
.PP
Reimplemented from \fBSoFieldContainer\fP\&.
.SS "void SoTextureUnit::doAction (\fBSoAction\fP * action)\fR [virtual]\fP"
This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureUnit::callback (\fBSoCallbackAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.

.PP
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureUnit::GLRender (\fBSoGLRenderAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.

.PP
This is called during rendering traversals\&. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureUnit::pick (\fBSoPickAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoPickAction\fP\&.

.PP
Does common processing for \fBSoPickAction\fP \fIaction\fP instances\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureUnit::getBoundingBox (\fBSoGetBoundingBoxAction\fP * action)\fR [virtual]\fP"
Action method for the \fBSoGetBoundingBoxAction\fP\&.

.PP
Calculates bounding box and center coordinates for node and modifies the values of the \fIaction\fP to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node\&.

.PP
Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureUnit::getMatrix (\fBSoGetMatrixAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoGetMatrixAction\fP\&.

.PP
Updates \fIaction\fP by accumulating with the transformation matrix of this node (if any)\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "uint32_t SoTextureUnit::getMaxTextureUnit (void )\fR [static]\fP"
Returns the maximum number of texture units for the current GL context\&. Do not call this method if you don't have a current active GL context\&. You should also know that your OpenGL driver supports multi-texturing\&.

.PP
This function is provided only to be compatible with TGS Inventor\&. It's better to use cc_glglue_max_texture_units() if you're using Coin (declared in Inventor/C/glue/gl\&.h)\&. 
.SH "Member Data Documentation"
.PP 
.SS "\fBSoSFInt32\fP SoTextureUnit::unit"
The texture unit which will be used for texture nodes following this node in the traversal\&. Default value of the field is 0\&. 
.SS "\fBSoSFEnum\fP SoTextureUnit::mappingMethod"
The mapping method for this unit\&. Default is IMAGE_MAPPING\&.

.PP
This field is not currently supported in Coin\&. It is included to support TGS' API\&. We might support the field in the future\&.
