DESCRIPTION

This node defines a set of 3D surface normal vectors to be used by vertex-based shape nodes that follow it in the scene graph. This node does not produce a visible result during rendering; it simply replaces the current normals in the rendering state for subsequent nodes to use. This node contains one multiple-valued field that contains the normal vectors.
 
Surface normals are needed to compute lighting when the Phong lighting model is used. Most vertex-based shapes that use normals can compute default normals if none are specified, depending on the current normal binding.

FIELDS


SoMFVec3f vector
 

Surface normal vectors.
 

METHODS


SoNormal()
 

Creates a surface normal node with default settings.
 


static SoType getClassTypeId()
 

Returns type identifier for this class.
 

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoRayPickAction
 

Sets the current normals in the traversal state.
 

FILE FORMAT/DEFAULTS
