# SoFaceDetail(3iv)

stores detail information about vertex-based shapes made of faces

## NAME

SoFaceDetail — stores detail information about vertex-based shapes made of faces

## INHERITS FROM

SoDetail \> SoFaceDetail

## SYNOPSIS

**#include \<Inventor/details/SoFaceDetail.h\>**

Methods from class SoFaceDetail:

	**SoFaceDetail()**\
 **virtual** 	**~SoFaceDetail()**\
 **long**	**getNumPoints() const**\
 **const SoPointDetail \***	**getPoint(int i) const**\
 **int32\_t**	**getFaceIndex() const**\
 **int32\_t**	**getPartIndex() const**\
 **static SoType**	**getClassTypeId()**

Methods from class SoDetail:

**SoDetail \***	**copy() const**\
 **virtual SoType**	**getTypeId() const**\
 **SbBool**	**isOfType(SoType type) const**

## DESCRIPTION

**This class contains detail information about a point on a face in a vertex-based shape made of faces. The information includes the number of points in the face, the points forming the vertices of the face,** **and the index of the face within the shape.**

**Note that when an SoFaceDetail** is returned from picking (in an **SoPickedPoint**), it will contain details for all points defining the face that was intersected. However, when an **SoFaceDetail** is created for a triangle produced during primitive generation (in an **SoPrimitiveVertex**), it will contain details for only the three vertices of the triangle.

## METHODS

	**SoFaceDetail()**\
 **virtual** 	**~SoFaceDetail()**\
 Constructor and destructor.

**long**	**getNumPoints() const**\
 Returns the number of points in the face.

**const SoPointDetail \***	**getPoint(int i) const**\
 Returns information about the point forming the **i**'th vertex of the face, represented as an **SoPointDetail**.

**int32\_t**	**getFaceIndex() const**\
 Returns the index of the face within the shape.

**int32\_t**	**getPartIndex() const**\
 Returns the index of the part containing the face within the shape.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.
