A couple of notes;
- I miss the 'flow split'; where transform can become handler by making
an initialize(), doit() and exit() stage. And how an API for this would
- Generic 'type independance' sounds good, but nevertheless you'll find
that some types just need complete different handling. Like vertices
vs. objects, or armature bones. And will we use this for single-value
editing like weights, path-twisting, etc?
- My previous remark on 'abusing transform()' was serious... but what I
meant is transform() can become that good that we don't have to abuse
I hope a drilling tool then can also use the full power of transform,
which would be good.
- You're warned Ipos and ActionChannels need to be inserted somehow...
that's brain-crunch stuff to get right!
- yes you'll need the old values in the struct, it's better not to do
any incremental stuff, but always transform from fixed start (=old)
- The MMB workflow suggestion; I'd like to see that... current MMB
trick works based on largest motion, not closest axis. But it might
- Quote: "Transformation is always done on the matrix and then
transfered back"? That's very dangerous... I still have to see the
first reliable routine to extract size/rot/loc values on a compatible &
predictable level. Here especially ipo key inserting makes it hard.
- As you might have noticed, the Object has a quat already, it was
scheduled to be used from some moment in the future... with old eulers
only optional, or even completely converted.
- What I really miss is the target & result of this work... what is the
