NAME

       glutSolidTorus, glutWireTorus - render a solid or wireframe torus (doughnut) respectively.

SYNTAX

       void glutSolidTorus(GLdouble innerRadius,
			   GLdouble outerRadius,
			   GLint nsides, GLint rings);
       void glutWireTorus(GLdouble innerRadius,
			  GLdouble outerRadius,
			  GLint nsides, GLint rings);

ARGUMENTS

       innerRadius
		 Inner radius of the torus.

       outerRadius
		 Outer radius of the torus.

       nsides	 Number of sides for each radial section.

       rings	 Number of radial divisions for the torus.

DESCRIPTION

       glutSolidTorus  and  glutWireTorus  render  a  solid or wireframe torus (doughnut) respectively centered at the modeling coordinates origin
       whose axis is aligned with the Z axis.

NAME

       gluPartialDisk - draw an arc of a disk

C SPECIFICATION

       void gluPartialDisk( GLUquadric* quad,
			    GLdouble inner,
			    GLdouble outer,
			    GLint slices,
			    GLint loops,
			    GLdouble start,
			    GLdouble sweep )

PARAMETERS

       quad    Specifies a quadrics object (created with gluNewQuadric).

       inner   Specifies the inner radius of the partial disk (can be 0).

       outer   Specifies the outer radius of the partial disk.

       slices  Specifies the number of subdivisions around the z axis.

       loops   Specifies the number of concentric rings about the origin into which the partial disk is subdivided.

       start   Specifies the starting angle, in degrees, of the disk portion.

       sweep   Specifies the sweep angle, in degrees, of the disk portion.

DESCRIPTION

       gluPartialDisk renders a partial disk on the z = 0 plane. A partial disk is similar to a full disk, except that only the subset of the disk
       from start through start + sweep is included (where 0 degrees is along the +y axis, 90 degrees along the +x axis, 180 degrees along the	-y
       axis, and 270 degrees along the -x axis).

       The partial disk has a radius of outer, and contains a concentric circular hole with a radius of inner. If inner is 0, then no hole is gen-
       erated. The partial disk is subdivided around the z axis into slices (like pizza slices), and also about the z axis into rings  (as  speci-
       fied by slices and loops, respectively).

       With  respect  to orientation, the +z side of the partial disk is considered to be outside (see gluQuadricOrientation).	This means that if
       the orientation is set to GLU_OUTSIDE, then any normals generated point along the +z axis. Otherwise, they point along the -z axis.

       If texturing is turned on (with gluQuadricTexture), texture coordinates are generated linearly such that where r = outer, the value at  (r,
       0, 0) is (1.0, 0.5), at (0, r, 0) it is (0.5, 1.0), at (-r, 0, 0) it is (0.0, 0.5), and at (0, -r, 0) it is (0.5, 0.0).
