Method Detail

draw

public void draw(float radius,
        int slices,
        int stacks)

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 glu.quadricOrientation), 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 glu.quadricTexture), then 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 +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.
