public class SoNormal extends SoNode
Node that defines surface normals for shapes. 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.

File format/default:

Normal {

    vector [ ]
}

Action behavior:

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