Sets the current normal vector.
void WINAPI glNormal3dv( const GLdouble *v );
A pointer to an array of three elements: the x, y, and z coordinates of the new current normal.
This function does not return a value.
The current normal is set to the given coordinates whenever you call the glNormal3dvfunction.
Byte, short, or integer arguments are converted to floating-point format with a linear mapping that maps the most positive representable integer value to 1.0, and the most negative representable integer value to -1.0.
Normals specified by usingglNormal3dv need not have unit length. If normalization is enabled, then normals specified with glNormal3dv are normalized after transformation. You can control normalization by using glEnable and glDisable with the argument GL_NORMALIZE. By default, normalization is disabled. You can update the current normal at any time. In particular, you can callglNormal3dvbetween a call to glBegin and the corresponding call to glEnd. The following functions retrieve information related to glNormal3dv:
glGet with argument GL_CURRENT_NORMAL
glIsEnable with argument GL_NORMALIZE
