## DESCRIPTION

**A field containing a plane equation (an SbPlane).**

**SoSFPlanes** are written to file as four floating point values separated by whitespace. The first three are the normal direction of the plane, the fourth is the distance of the plane from the origin (in the direction of the normal).

## METHODS

**static SoType**	**getClassTypeId()**\
 **virtual void**	**getTypeId() const**\
 Returns the type for this class or a particular object of this class.

**const SbPlane &**	**getValue() const**\
 Returns this field's value.

**const SbPlane &**	**operator =(const SbPlane & newValue)**\
 **void**	**setValue(const SbPlane & newValue)**\
 Sets this field to **newValue**.

**int**	**operator ==(const SoSFPlane &f) const**\
 **int**	**operator !=(const SoSFPlane &f) const**\
 Returns TRUE if **f** is of the same type and has the same value as this field.
