I tried to incoporate your change into shader.ijs
with f8/f9 to change value for gl_translate.
The changes lines are marked by NB. <
pressing f8/f9 can trigger repaint and the matrix
display also updated, but I can't see the cube at all.
Pressing F10 to start original code, the cube came back.

Dear all,
I would like to know what is the best way to flatten a deeply nested array
to a single level of boxing. Essentially:
(0 ;<(1;'a');<(2;<<'b')),:|.(3 ;<(4;'c');<(5;<<'d'))
would yield
0;1;2;3;4;5;'a';'b';'c';'d'
where order is unimportant.
Thanks!

I think you can't call a_g_paint directly. Even you call, opengl code won't
work because it must be executed inside paint event.
you can trigger a repaint gl_paint and let the OS to call event handler.
Why didn't you print out the y to see what is its value?

Yes, I think I understand the normally gl_paint is called from event
handler,
and I am calling gl_paint directly myself. Can you tell me where the code
for event handler is so that I can see if it is making another call that I
am not aware of?

a_g_paint is called from event handler, not from your code.
unless you had called this verb directly.
the viewport is glu_lookat, but I forgot most of it already.

Bill (et al),
Can you comment on my initial assumption that shader.ijs is not really
moving the cube but is moving the eye in relation to the cube, (and that a
more common way to move **multiple** objects is to move them, not the eye.)
Bill,
Replying to your 3 comments:
1)I have stopped the time
This works OK for me (in Windows):
NB.* fcopy: copy x (fully-pathed name of file) to y.
fcopy=: 4 : 'shell (''copy "'',x,''" "'',y,''"'') rplc ''/\'''
NB.EG 'C:\Temp\foo.txt' fcopy 'E:\Perm\foo2.txt'
I just noticed I had a commented-out version of "fcopy" using the win32api
with 'CopyFileA', so pr
I think you should stop the timer so as not to interference your code.
handler for paint event (and all events) receive no y argument.
not sure what it looks like if mvp is translate only without projection
from 3D to 2D. the screen is flat 2D.

Bill,
I have changed the original F10 to produce `paint 0` and the usual key to
produce `paint 1`.
I have critical new information though: If I press x and y several times to
reposition the cube in the expected manner, and then I press F10. The cube
seems to go back to its original position (appr
It's quite difficult to follow what you had changed and the final script.
Anyway mvp is recalculated inside paint event, not when F10 is pressed.
