This commit attempts to fix some of the problems with the accuracy of strokes recorded.
I've disabled the post-draw smoothing of strokes as it deviated from the source stroke too much. This was introduced to try to eliminate the effects of fine 'jitter' (which is especially noticable when using optical mice + fast computer).
Now, I've introduced two thresholds which determine the 'minimum' distances that the mouse needs to have moved from the previous mouse-coordinates recorded, to be recorded. These are currently hardcoded, but may be exposed in the UI if there is significant need to do so.
- The first is for the distance that the mouse must have moved on both axes to be considered.
- The second is for the 'pythagorean' distance that needs to have been travelled by the mouse.
* For constraint mesh-targets, the check for whether the target mesh was in EditMode didn't check to see if the target mesh was the mesh in EditMode.
Thanks jaguarandi for catching that!
* Bumped up size of buffer for grease-pencil drawing after seeing a program written in 1989 that had a 100 times larger buffer
Early Ehlinger reported a deadlock when a script tells Blender to render an animation and there are pynodes. While investigating I saw related crashes in bg (blender -b) mode, still not fixed. This commit tries to fix the problem for interactive mode, then. What it does is releasing the lock before rendering and relocking after that, like theeth suggests in the bug report:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=17389&group_id=9
It turns out the material AmbCol property was never working properly, or even supported in the renderer, so I've removed it. Also included is a fix to make the 'Amb' input work properly too.
left overs from new particles
-wind and force did not work if aero or edge collision was activated.
-force field had flipped sign compared to particles
tsk who thinks a attractive force should negative sign? well... i am passionless with that.
-adapted effect of wind and fields on softbodies such that softbody "particles" and particle "particles" behave consistently
note!
effect of wind is 1/25 compared to before
other forces 1/10
New Stuff:
* Alt-XKEY / Alt-DelKey will now activate the Grease Pencil "Erase" menu. This will only show up when it's relevant (i.e. when there exists Grease Pencil data). It should make it faster to quickly delete the last stroke made. This hotkey has been added to the tooltips of the relevant buttons.
* Finished off colouring of 'active' layers panel so that they are now easily identify-able. This could also be done for Constraints, but the 'active' one isn't that important there.
Bugfixes:
* Fixed bug with drawing gp-data sources in the Action Editor, which resulted in missing icons.
* Fixed buttons in Grease Pencil panel. My hasty attempt last night at making the Action Editor to refresh was causing problems.
* Added a (hopefully temporary) button that will be used to prevent drawing from occurring with Shift-LMB. This is useful when trying to select stuff sometimes, with LMB as select-button, especially when selecting a bunch of closely spaced bones might be interpreted as a new stroke.
Based on user feedback, I've made some changes to the Grease Pencil UI (most notably in 'Time Editing' facilities).
* 'Edit Timing' button gone
* Pin button and '<Grease Pencil Data' string gone from Action Editor
* Action Editor in 'Grease Pencil' mode now displays all grease-pencil datablocks for current screen.
* AE: GP-Datablocks are drawn like 'groups', with an expand/collapse button to show/hide layers. Its name shows the type of space it comes from, and shows indicative status info (i.e. for 3d-view, it shows view-angle)
* Added refresh calls for action editor after editing relevant data.
I haven't tested all tools yet, but most should be stable.
Also, I've removed some unnecessary buttons, and added a few tooltips. There's also some experimental code to try to get clearer indication of 'active' layer.
Fixes: [#17315] Sequencer: after undo there's no active object
closes: [#17357] fix for bug #17315 - Sequencer: after undo there's no active object
(kiemdoder: thanks for the patch, had to do it in a little bit different way,
since sort_seq will kill your sort order idea...)
The min/max parameters define a minimum/maximum angle
that the object axis can have with the reference
direction without being constrainted. The angle is
expressed in degree and is limited to 0-180 range.
The min/max parameters define a conical free zone
around the reference direction.
If the object axis is outside that free zone, the
actuator will tend to put it back using as a temporary
reference direction the vector that is exactly at
min or max degree of the reference direction
(depending if the axis angle is below the minimum
or above the maximum) and is located in the plane
formed by the axis and the reference direction.
With a low damping value, this is equivalent to
clamping the axis orientation within min/max degree
of the reference direction.
Backward compatibility corresponds to the absence
of free zone: min = max = 0.
Grease Pencil is a tool which allows you to draw freehand in some views, allowing you to annotate/scribble over the contents of that view in either 2d or 3d. This facilitates many easier communication and planning abilities.
To use, simply enable it from the View menu (choose 'Grease Pencil...' and click 'Use Grease Pencil'). Then, click+drag using the left-mouse button and the shift-key held to draw a stroke.

Particle patch from Cédric Paille: bugfixes and child-particles export improvements for .getLoc(), part.getRot() part.getSize(), part.getAge() methods.
Also fix a bug with part.randemission getter (was using PART_BOIDS_2D instead of PART_TRAND), plus typos and duplications in API documentation.
Curve modifier on lattice suffered drawing updates, only when the system
was not animated though, missed depsgraph calls then.
Solved it by forcing lattice to always return displist for its vertices,
that's same as for how mesh/curve works now.
Specular render in Blender still had terminator problems... only the diffuse
part got "phong correction" applied. I didn't fix this before to not change
rendering results just before the release. Now there's time I hope?
Render results should only differ minimal, and only visible for low spec
hardness values (like 1 or 2)
the aspect of a block could become negative and default when scaling icons.
this is caused by the using viewRedrawForce (transforming a mesh) and drawing icons in the image panel.
must look into why bwin_getsinglematrix can give a negative value, probably because the opengl state is set incorrect.
This is still not correct because the aspect will be wrong. but at least it wont crash.
If you enable the Proxy and Custom Dir options and later disable
the Proxy (but not the Custom Dir options), Blender crash every
time that you try select the strip, because the proxy don't exist
anymore.
The solution: only draw the Custom Dir button if the Proxy
option is enable.
* samples that wernt loaded could crash blender - divide by zero errors from having 0 channels or bits.
* could also corrupt memory when selecting samples with long names. from the sample selector menu.
Small one: changed the string attribute in multilayer exr files to be:
"2.43 and newer"
To indicate that it's about compatibility of the exr file, not the version
Blender saved it in.
Ztransp OSA render did not include z values anymore in pass... this is
not good Z anyway (aliased), but at least it's back now.
Note: for composites using Z values: use FSA for superior results.
Patch submitted by Roelf De Kock (kiemdoder)
The parts of the patch affecting the timeline were have not been committed, as there was a better solution.
When searching failed to find any matches, the pointer to a matching pose was cleared. However, it wasn't reset upon clearing the invalid search-string, so a crash occurred.
When the NKEY is pressed in the Action Editor while hovering over the keyframes area, a floating properties panel can now be accessed. It shows relevant properties for the active channel, however this is currently only for Action Groups. Action Channel support will come later.
The key benefit of this panel is that it is now possible to edit the colour set used by a group. Also, there is a button for selecting all the channels in that group (which can also be done by simply Ctrl-Shift clicking on any group).
