pmv(3G) pmv(3G)
NAME
pmv, pmvi, pmvs, pmv2, pmv2i, pmv2s - specifies the first point of a
polygon
C SPECIFICATION
void pmv(x, y, z)
Coord x, y, z;
void pmvi(x, y, z)
Icoord x, y, z;
void pmvs(x, y, z)
Scoord x, y, z;
void pmv2(x, y)
Coord x, y;
void pmv2i(x, y)
Icoord x, y;
void pmv2s(x, y)
Scoord x, y;
All of the above routines are functionally the same. They differ only in
the type declarations of their parameters and in whether or not they
assume a two-dimensional or three-dimensional space.
PARAMETERS
x expects the x coordinate of the first point if a polygon.
y expects the y coordinate of the first point of a polygon.
z expects the z coordinate of the first point of a polygon.
DESCRIPTION
pmv specifies the starting point of a polygon. The next drawing command
will start drawing from this point. You draw a typical polygon with a
pmv, a sequence of pdr, and close it with a pclos.
Between pmv and pclos, you can only issue the following Graphics Library
subroutines: color, RGBcolor, cpack, lmdef, lmbind pdr, c family of
subroutines (for example, c3f), n family of subroutines (for example,
n3f), and v family of subroutines (for example, v3f). Only use lmdef and
lmbind to respecify materials and their properties.
EXAMPLE
The following sequence draws a square:

pmv(3G) pmv(3G)
pmv(0.0, 0.0, 0.0);
pdr(1.0, 0.0, 0.0);
pdr(1.0, 1.0, 0.0);
pdr(0.0, 1.0, 0.0);
pclos();
SEE ALSO
bgnpolygon, endpolygon, pclos, pdr, v
NOTES
pmv should not be used in new development. Rather, polygons should be
drawn using the high-performance v commands, surrounded by calls to
bgnpolygon and endpolygon.
There can be no more than 256 vertices in a polygon. Therefore, there
can be no more than 255 pdr calls between pmv and pclos.
