Overview
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
Normal {
vector [ ]
}
