Sorry for my in-exact sentence. I meant if there were a new gl3 command
"glDelay", then it will be possible to insert it to display list to provide
delay between drawing. for example
go =: 3 : 0
alloc__ogl HW
CLEARCOLOR =. ?4#2
glClearColor CLEARCOLOR
glClear GL_COLOR_BUFFER_BIT
glOrtho _1 1 _1 1 _1 1
glColor3d 0 0 0
glBegin GL_POLYGON
glVertex 1 ,0 ,0,1
glVertex 0 ,0.5 ,0,1
glVertex _1 ,0 ,0,1
glEnd ''
glDelay 5 NB. delay 5 second
draw__ogl''
wd'pshow;'
)
Having glDelay embedded into display list, so that whenever display list is
redrawed, there will be automatical delay. and
"go[go[go''"
will have 5 seconds of delay for each rendering.
Take it as a request for a new gl3 feature, but it may be difficult to implement
efficiently because the delay in paint event may make system freezing for a few
seconds in each repaint.

Bill,
Regarding glDelay, I could find no such command. But
there is a glFinish which is more forceful than glFlush used
in draw_keep and pixels_keep. But replacing Finish with
Flush did not change the result of my go verb.
