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.
