PROGRAM 2: Appearance of polymarkers
CHARACTERISTICS: ynny
OPERATOR SCRIPT:
GEOMETRY OF 3D POLYMARKERS: All the squares should contain a
polymarker with multiple asterisk markers. All but one should
have their vertices accurately circled by a polymarker. Identify
the polymarker which is not accurately marked.
GEOMETRY OF 2D POLYMARKERS: Same as GEOMETRY OF 3D POLYMARKERS,
above.
DESIGN:
set polymarker scale factor to reasonable size = 0.02 in WC
Divide screen up into 6 square labelled areas for all tests
sider = list of 6 sides from which cube may be viewed =
front,back,left,right,top,bottom
Throughout, use asterisk for actual polymarker, circle for
expected position.
TEST: #SR 1 4 7
"The appearance of a <polymarker 3> primitive should reflect
its 3D geometry after being transformed."
ngsq = no-good square = random integer from 1 to 6
generate 3D list of points, visually distinct from any side for
3D polymarker
for ix = 1 to 6
rotate to view from sider(ix)
display the 3D polymarker in square #ix
calculate expected position of vertices
if (ix = ngsq) then
distort expected vertices
endif
use 2D circle polymarker to mark expected vertices
next ix
OPQA/GEOMETRY OF 3D POLYMARKERS: Which polymarker does NOT have
all its asterisk vertices circled?
pass/fail depending on:
(operator identifies square #ngsq)
TEST: #SR 1 4 7
"The appearance of a <polymarker> primitive should reflect
its 2D geometry after being transformed."
ngsq = no-good square = random integer from 1 to 6
generate non-linear 2D list of points distinct from any side for
2D polymarker
for ix = 1 to 6
rotate 45 degrees around x and y axis into unit cube to show
z-values
rotate to view from sider(ix)
display the 2D polymarker in square #ix
calculate expected position of vertices
if (ix = ngsq) then
distort expected vertices
endif
use 2D circle polymarker to mark expected vertices
next ix
OPQA/GEOMETRY OF 2D POLYMARKERS: Which polymarker does NOT have
all its asterisk vertices circled?
pass/fail depending on:
(operator identifies square #ngsq)
