gluSphere

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.
