ANIMATION DEV: Grease pencil mode, what does it do?

[Aligorith]

Just a quick update...
http://aligorith.googlepages.com/greasepencil_11.patch

Nothing much to see here, but there is now OpenGL render support. In the backend, I've done some cleanups in preparation for the code to be available in more places, which have also allowed for htis feature.

Currently, I've still got the following items on my todo list (they have been there for a while too):
* sort out the view-alignment/scaling issue (strokes to 3d-strokes on a drawing plane?)
* implement an eraser! (this is deceptively more difficult than it would seem)
* fix the 'undo' bug... (code is there, but it's not working, perhaps as its per view atm)
* improve tools for frame management

Laters,

mmm quite interesting!

be totally amazing if the sketch lines could be curve objects...

great stuff nonetheless.....

it works great

possible bug..... the pencil disappear while joining 2 views .

waiting for updates !

Man people are always feature crazy. hehe. Anyway. I like the grease pencil concept. Keep up the good work. I like where this is going. Reminds me a lot of tools I've used in other programs.

Another update:

http://aligorith.googlepages.com/greasepencil_12.patch

Changes:
* XKEY/DELKEY can now be used to access options for deleting various things (i.e. erase last stroke, active frame, active layer)
* Fixed a bug with the code for adding new frames (was adding in wrong place)
* Fixed a few other not-so-visible bugs

EDIT: Last patch for today... just a few minor tweaks
http://aligorith.googlepages.com/greasepencil_12b.patch

* Enabled checks for full cache, so now "long"+slow strokes are possible
* Strokes are now drawn as smooth (i.e. antialiased) lines

Enjoy,
Aligorith

sounds really cool... can't test .patch files, also am on windows... Anyway, following the progress

Hi, Aligorith! =)

This is indeed an awesome feature. I'm at work now (yeah, on sunday) but as soon as I get home, I'll compile with your patch.

Thanks a lot for all this animation goodies you keep giving us. =) I'm gonna use it a lot.

Cheers

Hi all,

Here is the latest patch:
http://aligorith.googlepages.com/greasepencil_13.patch

This latest patch introduces the significant ability to "draw in 3d". The "Draw in 3D" option must be turned on for this to work.

Haven't had the chance to apply the patch and build it yet, just scanning through the posts, so correct me if I'm not understanding how it works...

But I wanted to ask, would it be possible to bind the grease pencil markups to a camera? For instance you wouldn't see the grease pencil marks unless you were viewing through the camera, and if you have multiple cameras in the scene, each camera could have it's own grease pencil markups. And as the camera moved, the grease marks would move with it, bound to the camera plane. The grease marks would be keyed as to which frame they are drawn in and which frame they are erased in.

Maybe this doesn't work with the way the current implementation is designed...

I have to say the delete last stroke feature is very useful. I haven't had a chance to use the latest patch yet, but i think once i have used it ill like it and will use it from here on out.

[Virgilio]

Hey, guys. =D

Just in case some of you are interested, I wrote a little article on how can you apply this patch and compile on Ubuntu and also how to use this very neat feature:

I think this tool is not only useful for animators.
People who just model might find it handy as well for quick and dirty topology planning, pointing modeling artifacts or suggesting mesh improvements.

Great work!


btw: is it me, or these svn builds have different (much nicer!) icon set than official version (?)

[Extrudeface]

yep,useful for that too... but the load of freedom that a feature like that can add for keying ,poses, planning animation, etc...

[Aligorith]

Just a quick bump... expect a new patch in the next day or so, which will include the following:
* Support for this in Sequencer (Image Preview), and Nodes
* Ability to load a set of annotations into the Action Editor to adjust timing of frames
* "Toolified" painting
* Improved UI
* ... and maybe a few more little goodies ...

I've holding off doing much major work on this last week, while waiting to see how long it would be before I'd get my laptop back from the repair-shop. Anyways, it's full steam ahead on my trusty (albeit slow and crappy) desktop

Aligorith that looks amazing. I don't have to hop over to pencil anymore!

Can someone post a MacIntel build? I'm struggling trying to build myself.

[dagobert]

I can draw my thumbnail directly over my scene and animate according to that.
very usefull.
How do you know it was my birthdate?
if you know someone that can implement a bone stretching in the ik solver that preserve volume, it will be christmas in summer for me

[hdd]

Should be great to see this tool integrated with the retopo tool.
just 2c.

Markers and grease pencil is pure gold for animation.

Lastest patch:
http://aligorith.googlepages.com/gpencil_16.patch

Notes:
* Files from older versions of this patch may not load correctly
* To draw, use the hotkey Ctrl-D instead of going into a separate mode. LMB to draw, and use standard controls to exit drawing.
* UI for this has been reworked (layers now appear as a stack)
* Colour picker in panel now works correctly (at least during tests here)
* Layers are now automatically named
* This should work in the Nodes editor too
* Sequencer stuff is not quite working yet...
* Action Editor support hasn't been completed yet
* There may be a few more bugs in this patch than in previous ones

Laters,
Aligorith

A small update on previous patch:
http://aligorith.googlepages.com/gpencil_17.patch

Changes (mostly bugfixes):
* Action Editor can now display Grease Pencil data for editing timing, but actual editing will still have to wait
* Locked layers cannot be painted on
* Status info was drawn twice for nodes window (status info button has been removed)
* Drawing of camera borders was affected by grease-pencil drawing not correctly restoring some OpenGL drawing settings (thanks broken)
* Newly added grease-pencil data in the Nodes Editor will add strokes stuck to the view/canvas

Known Issues:
* Events handling in Nodes Editor is still dodgy (so Adding/Deleting layers, etc. using the panel doesn't work. Also, some UI widgets may not work correctly).
* Sequencer view still cannot display the panel correctly
* Action Editor doesn't get refreshed after drawing on a new layer

Enjoy,
Aligorith
