NAME

defbasis − defines a basis matrix

SPECIFICATION

C
defbasis(id, matrix)
long id;
Matrix mat;

FORTRAN
subroutine defbas(id, mat)
integer*4 id
real mat(4,4)

Pascal
procedure defbasis(id: longint; var mat: Matrix);

DESCRIPTION

defbasis defines basis matrices to generate curves and patches.  matrix is saved and is associated with id.  id can be used in subsequent calls to curvebasis and patchbasis.
