.SH NAME
SoTextureCoordinateNormalMap \- 
.PP
The \fBSoTextureCoordinateNormalMap\fP class generates texture coordinates by projecting onto a surrounding texture\&.
.PP
The texture specifying the enviroment will be mapped around the scenegraph below this node using a sphere\&. The texture will be mapped onto the scenegraph taking camera position into account\&. This will lead to an object reflecting its enviroment\&.

.SH "Detailed Description"
.PP 
The \fBSoTextureCoordinateNormalMap\fP class generates texture coordinates by projecting onto a surrounding texture\&.
.PP
The texture specifying the enviroment will be mapped around the scenegraph below this node using a sphere\&. The texture will be mapped onto the scenegraph taking camera position into account\&. This will lead to an object reflecting its enviroment\&. 

Here is a scenegraph example showing how enviroment mapping can be applied to an object:
.PP
\fC #Inventor V2\&.1 ascii\fP
.PP
\fCSeparator {\fP
.PP
\fC Texture2 { filename 'ocean\&.jpg' # the enviroment, in this case ocean } TextureCoordinateNormalMap {}\fP
.PP
\fC Cube {} # the enviromentally mapped object } \fP

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi
.PP
.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP subclasses\&. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.
.PP

.PP
Reimplemented from \fBSoTextureCoordinateFunction\fP\&.
.SS "const \fBSoFieldData\fP * SoTextureCoordinateNormalMap::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP
Reimplemented from \fBSoTextureCoordinateFunction\fP\&.
.SS "void SoTextureCoordinateNormalMap::doAction (\fBSoAction\fP *action)\fC [virtual]\fP"
This function performs the typical operation of a node for any action\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureCoordinateNormalMap::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP"
Action method for the \fBSoGLRenderAction\fP\&.
.PP
This is called during rendering traversals\&. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureCoordinateNormalMap::pick (\fBSoPickAction\fP *action)\fC [virtual]\fP"
Action method for \fBSoPickAction\fP\&.
.PP
Does common processing for \fBSoPickAction\fP \fIaction\fP instances\&. 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "void SoTextureCoordinateNormalMap::callback (\fBSoCallbackAction\fP *action)\fC [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\&.
