All,
Attached
is the discussion I had with Lofton over the weekend regarding the transform
spec. ***_draft4 is what Lofton
already had a look at, updates*** is the remaining stuff including the
table. We can also remove the
bounding box sentence. It’s a
leftover from previous drafts but not needed
anymore.
Thanks
and regards
Ulrich

Draft
Hi Ulrich,
This is an excellent piece of
work. Please congratulate Airat.
If anything, it is my initial
sense that it is might more than we need, particularly the presence of both
variants (around origin, and around specified point) for the convenience
functions scale, rotate, translate.
There are also some statements that I
need to think about -- don't understand on first reading. E.g., the 1st
paragraph of "General remarks", about the need to specify a bounding box via
some API.
NEXT STEP: I think you should get this to the TC as soon
as possible. There are some things that we need to discuss and resolve
Wednesday, before I attempt to implement the stuff in the 2.1 draft. These
are complicated technical questions and I don't want to prejudge the
answers.

Hi Lofton,
Attached you
will find the text for the transform functions. The text is not structured
as in your WebCGM 2.1 draft as we don t know what you want to put into chapter
5.4.4. It appears as if more than half of the text can go
there.
I agree. I will try to put most of the text
there, with references to it.
Airat will still work on the XCF
chapter 4 today. In addition, in his submission he is referring to a
Transformation Style Properties Table in accordance with Stuart s text, but I
don t see it. I will thus ask him to prepare one. If you see topics
missing (for example, I find no mentioning on the inheritance or child node
behavior issues) please tell him. Airat should also be available tomorrow
so that he can prepare an updated delivery on Sunday evening
(PST).
He can put XCF into a separate document, if
easier.
Airat also told me that he put
the TransformSP functions at the picture interface (as in chapter 5.7.5) while I
mentioned we would put them at the APS interface. I trust Airat
here.
Okay. That is another topic for the TC to
discuss.
Thanks,
-Lofton.
Thanks and
regards
Ulrich
