- void patchbasis
- (long tid,long uid)
Define the t and u basis matrix id's of a patch. It is
assumed that tbasisid and ubasisid have matrices associated
with them already (this is done using the
defbasis call).
- void patchprecision
- (long tseg,long useg)
Set the minimum number of line segments making up
curves in a patch.
- void patchcurves
- (long nt,long nu)
Set the number of curves making up a patch.
- void rpatch
- (Matrix gx,Matrix gy,Matrix gz,Matrix gw)
Draws a rational patch in the current basis, according
to the geometry matrices gx, gy, gz, and gw.
- void patch
- (Matrix gx,Matrix gy,Matrix gz)
Draws a patch in the current basis, according to the
geometry matrices gx, gy, and gz.
