The +sphere is subdivided around the \f2z\fP axis into slices and along the +\f2z\fP axis +into stacks (similar to lines of longitude and latitude). +.P +If the orientation is set to _gluconst(OUTSIDE) +(with _cmnd(QuadricOrientation)), then any normals generated +point away from the center of the sphere. +Otherwise, they point toward the center of the sphere. +.P +If texturing is turned on (with _cmnd(QuadricTexture)), then texture +coordinates are +generated so that \f2t\fP ranges from 0.0 at $ z ~=~ -^_eqnparam2 $ to 1.0 at +$ z ~=~ _eqnparam2 $ (\f2t\fP increases linearly along longitudinal +lines), +and \f2s\fP ranges from 0.0 at the +\f2y\fP axis, to 0.25 at the ++\f2x\fP axis, +to 0.5 at the \-\f2y\fP axis, to 0.75 at the \-\f2x\fP axis, and back to 1.0 +at the +\f2y\fP axis. +.SH SEE ALSO +_cmnd(Cylinder), _cmnd(Disk), _cmnd(NewQuadric), +_cmnd(PartialDisk), _cmnd(QuadricOrientation), +_cmnd(QuadricTexture) -- cgit v1.2.3
