PROGRAM 3: Behavior of rotations

CHARACTERISTICS: nnnn

OPERATOR SCRIPT: passive test.

DESIGN:

TEST: #SR 1 2 7
      "<Rotate x> should return a correct representation for the
       transformation to rotate a 3D point counterclockwise
       around the x-axis by the specified number of radians."

Set rotate x parameter rotang to 5.678
<Rotate x> with rotang returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 8
      "<Rotate y> should return a correct representation for the
       transformation to rotate a 3D point counterclockwise
       around the y-axis by the specified number of radians."

Set rotate y parameter rotang to -0.007373
<Rotate y> with rotang returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 9
      "<Rotate z> should return a correct representation for the
       transformation to rotate a 3D point counterclockwise
       around the z-axis by the specified number of radians."

Set rotate z parameter rotang to 8.52525
<Rotate z> with rotang returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 10
      "<Rotate> should return a correct representation for the
       transformation to rotate a 2D point counterclockwise
       around the origin by the specified number of radians."

Set rotate parameter rotang to -11.1111
<Rotate> with rotang returns act3x3 = actual array
Compute exp3x3 = expected array
pass/fail depending on (act3x3 represents same transformation as exp3x3)
