17 | class Normal from Vrml inherits TShared from MMgt |
18 | |
19 | ---Purpose: defines a Normal node of VRML specifying properties of geometry |
20 | --- and its appearance. |
21 | -- This node defines a set of 3D surface normal vectors to be used by vertex-based shape |
22 | -- nodes (IndexedFaceSet, IndexedLineSet, PointSet) that follow it in the scene graph. This |
23 | -- node does not produce a visible result during rendering; it simply replaces the current |
24 | -- normals in the rendering state for subsequent nodes to use. This node contains one |
25 | -- multiple-valued field that contains the normal vectors. |
