@ SOLID
Shape is known to be solid.
@ UNKNOWN_SHAPE_TYPE
Nothing is known about shape.
@ CONVEX
Faces are all convex.
@ UNKNOWN_FACE_TYPE
Nothing is known about faces.
@ UNKNOWN_ORDERING
No ordering info is known.
@ COUNTERCLOCKWISE
Vertices are ordered CCW around faces.
@ CLOCKWISE
Vertices are ordered CW around faces.
Node that provides hints about shapes.
FaceType
Hints about faces of shape: if all faces are known to be convex or not.
SoSFEnum vertexOrdering
Indicates how the vertices of faces are ordered.
SoSFEnum shapeType
Indicates whether the shape is known to enclose a volume (SOLID) or not.
SoShapeHints()
Creates a shape hints node with default settings.
static void initClass()
SoSFBool useVBO
Allows shapes to make use of vertex buffer objects if available.
SoSFEnum faceType
Indicates whether each face is convex.
virtual void doAction(SoAction *action)
This method performs the "typical" operation of a node for any action.
VertexOrdering
Hints about ordering of face vertices: if ordering of all vertices of all faces is known to be consis...
