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.
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.
** Library:** Use Glu32.lib.
