The disk has a radius of +_param3, and contains a concentric circular hole with a radius +of _param2. If _param2 is 0, then no hole is generated. The disk is +subdivided around the \f2z\fP axis into slices (like pizza slices), and also +about the \f2z\fP axis into rings +(as specified by _param4 and _param5, respectively). +.P +With respect to orientation, the +\f2z\fP side of the disk is considered to be +"outside" (see _cmnd(QuadricOrientation)). +This means that if the +orientation is set to _gluconst(OUTSIDE), then any normals generated +point along the +\f2z\fP axis. Otherwise, they point along the \-\f2z\fP +axis. +.P +If texturing has been turned on (with _cmnd(QuadricTexture)), +texture coordinates are generated +linearly such that where $ r ~=~ _eqnparam3 $, the value at (\f2r\fP, 0, 0) is +(1, 0.5), at (0, \f2r\fP, 0) it is (0.5, 1), at (\-\f2r\fP, 0, 0) +it is (0, 0.5), and +at (0, \-\f2r\fP, 0) it is (0.5, 0). +.SH SEE ALSO +_cmnd(Cylinder), _cmnd(NewQuadric), _cmnd(PartialDisk), +_cmnd(QuadricOrientation), +_cmnd(QuadricTexture), _cmnd(Sphere) |
