There are variations on all these routines that end in s and also end
in i.
- void draw
- (Coord x,Coord y,Coord z)
Draw from current graphics position to (x, y, z), a point in world
coordinates.
- void rdr
- (Coord deltax,Coord deltay,Coord deltaz)
Relative draw. deltax, deltay, and deltaz are offsets
in world units.
- void draw2
- (Coord x,Coord y)
Draw from current graphics position to point (x, y).
(x, y) is a point in world coordinates.
- void rdr2
- (Coord deltax,Coord deltay)
Relative draw2. deltax and deltay are offsets in world
units.
