gluSphere

  • Article

The gluSphere function draws a sphere.

void gluSphere(
  GLUquadricObj *qobj,  GLdouble radius,  GLint slices,  GLint stacks);

Parameters

  • qobj
    The quadric object (created with gluNewQuadric).
  • radius
    The radius of the sphere.
  • slices
    The number of subdivisions around the z-axis (similar to lines of longitude).
  • stacks
    The number of subdivisions along the z-axis (similar to lines of latitude).

Remarks

The gluSphere function 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), 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): texture coordinates are generated so that t ranges from 0.0 at z = radius to 1.0 at z = radius (t increases linearly along longitudinal lines); and s ranges from 0.0 at the positive y-axis, to 0.25 at the positive x-axis, to 0.5 at the positive y-axis, to 0.75 at the positive x-axis, and back to 1.0 at the positive y-axis.

Requirements

**  Windows NT/2000:** Requires Windows NT 3.5 or later.
**  Windows 95/98:** Requires Windows 95 or later. Available as a redistributable for Windows 95.
**  Header:** Declared in Glu.h.
