OpenGL C bindings library: libGL.a
void gluQuadricNormals( GLUquadric* quad, GLenum normal)
The gluQuadricNormals subroutine specifies the desired normals for quadric objects rendered with the quad parameter option. Legal parameter values are as follows:
| GLU_NONE | No normals are generated. |
| GLU_FLAT | One normal is generated for every facet of a quadric. |
| GLU_SMOOTH | One normal is generated for every vertex of a quadric. This value is the default. |
| quad | Specifies the quadrics object created with the gluNewQuadric subroutine. |
| normal | Specifies the desired type of normals. Valid values are as follows: |
| /usr/include/GL/gl.h | Contains C language constraints, variable type definitions, and ANSI function prototypes for OpenGL. |
