SUBROUTINE TPWRZT1 (IERROR)
C
C PURPOSE To provide a simple demonstration of
C entry PWRZT with the THREED utility.
C
C USAGE CALL TPWRZT1 (IERROR)
C
C ARGUMENTS
C
C ON OUTPUT IERROR
C An integer variable
C = 0, if the test was successful,
C = 1, otherwise
C
C I/O If the test is successful, the message
C
C PWRZT TEST EXECUTED--SEE PLOTS TO CERTIFY
C
C is printed on unit 6. In addition, 1
C frame is produced on the machine graphics
C device. In order to determine if the test
C was successful, it is necessary to examine
C the plot.
C
C PRECISION Single
C
C REQUIRED ROUTINES PWRZT, THREED
C
C REQUIRED GKS LEVEL 0A
C
C LANGUAGE FORTRAN 77
C
C ALGORITHM The THREED package is called to establish a
C 3-D projection onto 2 space, and to draw the
C axis lines. PWRZT is then called to label
C the axes for a 3 space plot.
C
C EYE contains the (U,V,Z) coordinate of the eye position.
C
REAL EYE(3)
DATA EYE(1), EYE(2), EYE(3) /3.5, 3.0, 5.0/
C
C Initialize the error parameter.
C
IERROR = 1
C
C Select normalization transformation number 0.
C
CALL GSELNT (0)
C
C A call to SET3 establishes the mapping of 3 space coordinates onto
C the coordinate system of the graphics device.
C
CALL SET3 (.1,.9,.1,.9,0.,1.,0.,1.,0.,1.,EYE)
C
C Draw the 3 space axes.
