DESCRIPTION

This node specifies how the current normals are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently.

The bindings for faces and vertices are meaningful only for shapes that are made from faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow indexing. For bindings that require multiple normals, be sure to have at least as many normals defined as are necessary; otherwise, errors will occur.

FIELDS

SoSFEnum value

Specifies how to bind normals to shapes.

METHODS

SoNormalBinding()

Creates a normal binding node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoRayPickAction

Sets the current normal binding type.
