gluSphere — draw a sphere

## C Specification

```	GLdouble radius,
GLint slices,
GLint stacks )```

## Parameters

Specifies the radius of the sphere.

slices

Specifies the number of subdivisions around the z axis  (similar to lines of longitude).

stacks

Specifies the number of subdivisions along the z axis (similar to lines of latitude).

## Description

gluSphere draws a sphere of the given radius centered around the origin. The sphere is subdivided around the z axis into slices and along the  z axis  into stacks (similar to lines of longitude and latitude).

If the orientation is set to GLU_OUTSIDE  (with gluQuadricOrientation), then any normals generated  point away from the center of the sphere. Otherwise, they point toward the center of the sphere.

If texturing is turned on (with gluQuadricTexture), then texture  coordinates are  generated so that t ranges from 0.0 at $z\text{ }=\text{ }-\text{}\text{radius}$ to 1.0 at  $z\text{ }=\text{ }\text{radius}$ (t increases linearly along longitudinal lines), and s ranges from 0.0 at the +y axis, to 0.25 at the  +x axis,  to 0.5 at the -y axis, to 0.75 at the -x axis, and back to 1.0  at the +y axis.
