SoNormal — node that defines surface normals for shapes

Action Behavior

SoGLRenderAction,SoCallbackAction,SoRayPickAction
          Sets the current normals in the traversal state.

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

SoMFVec3fvector
          Surface normal vectors.

File Format/Defaults
