Drawing Routines.

draw(x, y, z)

Draw from current graphics position to (x, y, z). (x, y, z) is a point in world coordinates.

    Fortran:
         subroutine draw(x, y, z)
         real x, y, z

    C:
         draw(x, y, z)
              float     x, y, z;

    Pascal:
         procedure Draw(x, y, z: real)

rdraw(deltax, deltay, deltaz)

Relative draw. deltax, deltay, and deltaz are offsets in world units.

    Fortran:
         subroutine rdraw(deltax, deltay, deltaz)
         real deltax, deltay, deltaz

    C:
         rdraw(deltax, deltay, deltaz)
              float   deltax, deltay, deltaz;

    Pascal:
         procedure Rdraw(deltax, deltay, deltaz: real)

draw2(x, y)

Draw from current graphics position to point (x, y). (x, y) is a point in world coordinates.

    Fortran:
         subroutine draw2(x, y)
         real x, y

    C:
         draw2(x, y)
              float     x, y;

    Pascal:
         procedure Draw2(x, y: real)

rdraw2(deltax,deltay)

Relative draw2. deltax and deltay are offsets in world units.

    Fortran:
         subroutine rdraw2(deltax, deltay)
         real deltax, deltay

    C:
         rdraw2(deltax, deltay)
              float   deltax, deltay;

    Pascal:
         procedure Rdraw2(deltax, deltay: real)

sdraw2(x, y)

Draw in screen coordinates (-1.0 to 1.0).

    Fortran:
         subroutine sdraw2(x, y)
         real x, y

    C:
         sdraw2(x, y)
              float     x, y;

    Pascal:
         procedure Sdraw2(x, y: real)

rsdraw2(deltax, deltay)

Relative sdraw2. delatx and deltay are in screen units (-1.0 to 1.0).

    Fortran:
         subroutine rsdraw2(deltax, deltay)
         real deltax, deltay
    C:
         rsdraw2(deltax, deltay)
              float     deltax, deltay;

    Pascal:
         procedure Rsdraw2(deltax, deltay: real)
