The recent discussion of periodically using either
draw_keep or draw and using or not using alloc in the paint
verb, which is fundamentally a "glCallLists 1,#LISTS" has
direct implications for the turtle graphics simulation
system I have been developing. The upshot of this
discussion is that I believe it would be best for my
application if the new openGL utilities reverted somewhat to
the previous ones which relied on the (pseudo-)code
"[EMAIL PROTECTED] LISTS" for painting most of the
routine painting. I don't mean that a total reversion is
needed; the new approach is very effective. But the
reintroduction of some features would be very appealing.
I don't know whether the LISTS noun needs to be
filled with the lists that were created by stdlist and
stdlightlist, for example, but the LISTS values created by
genlist seem to be necessary. Of course I can do this
myself, but I would very much like to stick with the
utilities offered in jzopenglutil and that is where the
difficulty comes. I understand that Chris is going to rework
jzopenglutil to accommodate some additional "housekeeping"
and I guess I am saying that it would be best for me if that
revision also contemplated the need for reintroducing
genlist and LISTS as well as multiple paint verbs, not just
the one defined by GS_PAINT. The discussion thread focused
only on paints for resizing being different from paints
resulting from transforming the objects, but in a simulation
there are the startup paints and the simultaneous repaints
of multiple dynamic objects, also.
I realize I may not have explained my need well or
with enough detail, but I hope the idea is clear.
