Detailed Description
Specialized field for automatically generating normals from coordinates.
The resulting Normal node will contain normals per face if normalPerVertex is false or creaseAngle <=0. if normalPerVertex is true, then the normals returned will be a normal per vertex in coord if creaseAngle >= pi and a normal per vertex specified with coordIndex if 0 < creaseAngle < pi
routes_in[0] is the normalPerVertex field. routes_in[1] is the coord field. routes_in[2] is the coordIndex field. routes_in[3] is the ccw field. routes_in[4] is the creaseAngle field.

Create a new X3DNormalNode from the arguments given with one normal for each face specified.
- Parameters
-
_coord Node with the coordinates. coord_index The indices in coord for the vertices. _ccw Defines the ordering of the vertex coordinates of the geometry with respect to generated normal vectors used in the lighting model equations. If ccw is TRUE, the normals shall follow the right hand rule; the orientation of each normal with respect to the vertices (taken in order) shall be such that the vertices appear to be oriented in a counterclockwise order when the vertices are viewed (in the local coordinate system of the Shape) from the opposite direction as the normal.
- Returns
- A new Normal node with a normal for each vertex.
References H3D::Normal::vector.
◆ generateNormalsPerVertex() [1/2]
|
virtual |
Create a new X3DNormalNode from the arguments given with one normal for each vertex in coord.
The normal for each vertex will be the average of the normal of all faces using that vertex.
- Parameters
-
_coord Node with the coordinates. coord_index The indices in coord for the vertices. _ccw Defines the ordering of the vertex coordinates of the geometry with respect to generated normal vectors used in the lighting model equations. If ccw is TRUE, the normals shall follow the right hand rule; the orientation of each normal with respect to the vertices (taken in order) shall be such that the vertices appear to be oriented in a counterclockwise order when the vertices are viewed (in the local coordinate system of the Shape) from the opposite direction as the normal.

◆ generateNormalsPerVertex() [2/2]
|
virtual |
Create a new X3DNormalNode from the arguments given with one normal for each vertex specified by coord_index, i.e.
the number of normals will be the number of non-(-1) values in coord_index.
- Parameters
-
_coord Node with the coordinates. coord_index The indices in coord for the vertices. _ccw Defines the ordering of the vertex coordinates of the geometry with respect to generated normal vectors used in the lighting model equations. If ccw is TRUE, the normals shall follow the right hand rule; the orientation of each normal with respect to the vertices (taken in order) shall be such that the vertices appear to be oriented in a counterclockwise order when the vertices are viewed (in the local coordinate system of the Shape) from the opposite direction as the normal. crease_angle If the angle between the geometric normals of two adjacent faces is less than the crease angle, normals are calculated so that the faces are shaded smoothly across the edge; otherwise, normals are calculated so that a lighting discontinuity across the edge is produced.
- Returns
- A new Normal node with a normal for each vertex.
