The IRIS GL Sphere Library

OpenGL does not support the IRIS GL sphere library. You can replace your sphere library calls with quadrics routines from the GLU library. For more information about the GLU library, see the Open GL Programming Guide and OpenGL Utility Library.

The following table lists the OpenGL quadrics functions.

OpenGL function	Meaning
gluNewQuadric	Creates a new quadric object.
gluDeleteQuadric	Deletes a quadric object.
gluQuadricCallback	Associates a callback with a quadric object, for error handling.
gluQuadricNormals	Specifies normals: no normals, one per face, or one per vertex.
gluQuadricOrientation	Specifies direction of normals: outward or inward.
gluQuadricTexture	Turns texture-coordinate generation on or off.
gluQuadricDrawstyle	Specifies drawing style: polygons, lines, points, and so on.
gluSphere	Draws a sphere.
gluCylinder	Draws a cylinder or cone.
gluPartialDisk	Draws an arc.
gluDisk	Draws a circle or disk.

 

You can use one quadric object for all quadrics you want to render in similar ways. The following code sample uses two quadric objects to draw four quadrics, two of them textured.

GLUquadricObj    *texturedQuad, *plainQuad; 
 
texturedQuad = gluNewQuadric(void); 
gluQuadricTexture(texturedQuad, GL_TRUE); 
gluQuadricOrientation(texturedQuad, GLU_OUTSIDE); 
gluQuadricDrawStyle(texturedQuad, GLU_FILL); 
 
plainQuad = gluNewQuadric(void); 
gluQuadricDrawStyle(plainQuad, GLU_LINE); 
 
glColor3f (1.0, 1.0, 1.0); 
 
gluSphere(texturedQuad, 5.0, 20, 20); 
glTranslatef(10.0, 10.0, 0.0); 
gluCylinder(texturedQuad, 2.5, 5, 5, 10, 10); 
glTranslatef(10.0, 10.0, 0.0); 
gluDisk(plainQuad, 2.0, 5.0, 10, 10); 
glTranslatef(10.0, 10.0, 0.0); 
gluSphere(plainQuad, 5.0, 20, 20);
