3// This class is part of the Open Inventor Medical utility library.
4//
5// The medical utility classes are provided as a prebuilt library named
6// "fei_inventor_medical", that can be used directly in an Open Inventor
7// application. The classes in the prebuilt library are documented and
8// supported by Thermo Fisher Scientific. These classes are also provided as source code.

SoSFInt32 width
Specifies the width of the gnomon viewport in points (default is 100).
Definition Gnomon.h:72
void setGeometry(SoNode *geometrySceneGraph)
Replace the gnomon geometry (default is basic medical gnomon).
static void exitClass()
Finish using class (called automatically by InventorMedical::finish()).
Gnomon()
Constructor.
void setScale(SbVec3f scale)
Scale the size of the gnomon (default is 1,1,1).
