GLNORMAL() GLNORMAL() NAME glNormal3b, glNormal3d, glNormal3f, glNormal3i, glNormal3s, glNormal3bv, glNormal3dv, glNormal3fv, glNormal3iv, glNormal3sv - set the current normal vector delim $$ C SPECIFICATION void glNormal3b( GLbyte nx, GLbyte ny, GLbyte nz ) void glNormal3d( GLdouble nx, GLdouble ny, GLdouble nz ) void glNormal3f( GLfloat nx, GLfloat ny, GLfloat nz ) void glNormal3i( GLint nx, GLint ny, GLint nz ) void glNormal3s( GLshort nx, GLshort ny, GLshort nz ) PARAMETERS nx, ny, nz Specify the $x$, $y$, and $z$ coordinates of the new current nor- mal. The initial value of the current normal is the unit vector, (0, 0, 1). C SPECIFICATION void glNormal3bv( const GLbyte *v ) void glNormal3dv( const GLdouble *v ) void glNormal3fv( const GLfloat *v ) void glNormal3iv( const GLint *v ) void glNormal3sv( const GLshort *v ) PARAMETERS v Specifies a pointer to an array of three elements: the $x$, $y$, and $z$ coordinates of the new current normal. DESCRIPTION The current normal is set to the given coordinates whenever glNormal is is- sued. Byte, short, or integer arguments are converted to floating-point format with a linear mapping that maps the most positive representable in- teger value to 1.0, and the most negative representable integer value to -1.0. Normals specified with glNormal need not have unit length. If normaliza- tion is enabled, then normals specified with glNormal are normalized after transformation. To enable and disable normalization, call glEnable and glDisable with the argument GL_NORMALIZE. Normalization is initially dis- abled. NOTES The current normal can be updated at any time. In particular, glNormal can be called between a call to glBegin and the corresponding call to glEnd.
