NAME SoNormal SoNorm "" { node that defines surface normals for shapes }
INCLUDE nodes/SoNormal.h
DESC {
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.
\p
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.
}
FIELD vector { Surface normal vectors. }
METHOD "" SoNormal() { Creates a surface normal node with default settings. }
METHOD "" static SoType getClassTypeId() {
Returns type identifier for this class.
}
ACTION SoGLRenderAction, SoCallbackAction, SoRayPickAction {
Sets the current normals in the traversal state.
}
