Implemented general transformation tool Rotation for motion tracking data.
Mainly used to rotate pattern of markers.
To achieve most of usability, added configurable pivot point which is in fact
was median point before, but now can be chosen from boundbox center, median point
or individual centers. Individual centers means transformation would be performed
around marker's position, which is useful for rotation and scale.
Also implemented alternative scaling transformation -- hit S, S leads to
scaling of pattern area only.
TODO:
- clamping in some cases isn't working well, but that's easier to be resolved
after moving search are to marker.
- Update startup.blend so clip editor in Motion Tracking screen would be set to
Individual Centers by default.
This commit adds the ability to normalize patterns by their
average value while tracking, to make them invariant to global
illumination changes.
To see this in action, check out the "Lobby" scene from Hollywood
VFX. If you track the markers that are shadowed by the actress,
previously they would not track. With the scale adaption on, the
tracker would shrink the area to compensate for the changed
illumination, losing the track. With "Normalize" turned on, the
patch is correctly tracked and scale is maintained.
A remaining problem is that only the Ceres cost function is
updated to handle the normalization. The brute translation search
does not take this into account. Perhaps "Prepass" (see below)
should get disabled if normalization is enabled until I fix the
prepass to normalize as well.
There are a few other changes:
- Cleanups in tracking RNA comments.
- Bail out of the sampling loop early if the mask is zero; this
saves expensive samples of the image derivatives.
- Rename the wordy "Translation initialization" to "Prepass" at
Sebastian's suggestion.
- Fix a bug where the mask was ignored when sampling in the cost
functor.
This replaces the old style tracker configuration panel with the
new planar tracking panel. From a users perspective, this means:
- The old "tracking algorithm" picker is gone. There is only 1
algorithm now. We may revisit this later, but I would much
prefer to have only 1 algorithm. So far no optimization work
has been done so the speed is not there yet.
- There is now a dropdown to select the motion model. Choices:
* Translation
* Translation, rotation
* Translation, scale
* Translation, rotation, scale
* Affine (Not implemented yet)
* Perspective
The most stable is the "translation" parameterization. The
others work but still require some tweaking.
- The old "Hybrid" mode is gone; instead there is a toggle to
enable or disable translation-only tracker initialization. This
is the equivalent of the hyrbid mode before, but rewritten to work
with the new planar tracking modes.
- The pyramid levels setting is gone. At a future date, the planar
tracker will decide to use pyramids or not automatically. The
pyramid setting was ultimately a mistake; with the brute force
initialization it is unnecessary.
* Use custom names for the keying options enum. The old automated layout dumped
out lengthy names which
didn't work well with the limited UI widths we were using, leading to all the
interesting stuff getting cropped out
* Moved the "array target" options to be in line with the rest of the target
specification stuff. I've ended up flattening that set of options into a single
row, which seems to work quite well.
* Removed label from grouping method enum. There was a perfectly good section
header above, and with narrow UI's, the name of this and the one below ended up
looking the same/confusing.
Removing this option from the UI. Cyclic offset and/or other the myriad of other
half-working walk/stride cycle stuff has been removed pending further review at
a later date about what's really needed, and the best way to do so with regards
to different rig types (i.e. setup antagonistic).
Settings are shown in both the View3D toolbar and texture properties
panel; code is now in shared sculpt_brush_texture_settings() function
in properties_paint_common.py.
Also added a few new properties to the SculptCapabilities RNA to
replace "X in {Y, Z}" tests in the Python code.
Have to use a ugly hack, as for pose bones, rotscale transform matrix is not always the same as translate one... :/
Adresses feature request [#30979] snapping: "align rotation with the snapping target" and pose-mode.
* Changed Duplicate and Exture Operator fpr Curves/Surfaces to Duplicate/Extrude and Move, like for Mesh objects, for consistency. This is also consistent with Shift+D and E shortcut.
This fixes [#31429] Curve menu polish.
* Fixed a wrong tooltip for metaball duplication.
* Add CTRL+IKEY to invert the mask.
* Add ALT+MKEY to clear the mask.
* Change the 'Hide' menu in sculpt mode to 'Hide/Mask', adds entires
for clearing, filling, and inverting the mask, as well as hiding
masked regions.
- rename seqelements.push(file) --> filename
- rename SoundSequence.waveform --> show_waveform
- dont pass context to sequencer functions. editing any scenes sequence can be done, irrespective of context.
from Sebastian Nell (codemanx), with some edits
- Changed key shortcut to Shift+Enter.
- made into its own operator since it works differently to delete.
Now only one operator. Same options for vertices, edges and faces (so adds edges sorting, and some options to vertices sorting).
Face sorting should behave as previously. However, XSortVerts won’t pack anymore selected vertices at the begining of the vert array (as it used to), if you want such behavior you’ll have to first run SortElements with Selected action.
Also added bug ref I forgot in r46354 (armature.c).
for the contexts they appeared in
The VIEW3D_MT_transform menu was being used everywhere, although not all the
operators there applied to the current mode (e.g. the pivot point, animated
transforms to deltas, and a few others were Object-mode only). Split off the
offending parts into separate menus for the specific modes, and made these
extend the basic menu type.
As far as I could tell, these were really only still used for "virtual
modifiers", though we really don't use these anymore. Instead, most of the time,
people need to set these settings in armature modifiers directly (these didn't
even get copied over in that case). This was a source of confusion and
redundancy, so removing these now.
This change can be reverted if these were actually of some use out there...
* Added proper "update" operators in place of the abuse of the calculate
operators, so now the display ranges won't get overwritten everytime (with the
default values) you go to update the paths.
* Display range settings in properties editor now actually work. Before, the "In
Range" mode only displayed the entire paths.

The 'use_panorama' option is now part of a new Camera type: 'Panorama'.
Created two other panorama cameras:
- Equisolid: most of lens in the market simulate this lens - e.g. Nikon, Canon, ...)
this works as a real lens up to an extent. The final result takes the
sensor dimensions into account also.
.:. to simulate a Nikon DX2S with a 10.5mm lens do:
sensor: 23.7 x 15.7
fisheye lens: 10.5
fisheye fov: 180
render dimensions: 4288 x 2848
- Equidistant: this is not a real lens model. Although the old equidistant lens simulate
this lens. The result is always as a circular fisheye that takes the whole sensor
(in other words, it doesn't take the sensor into consideration).
This is perfect for fulldomes ;)
For the UI we have 10 to 360 as soft values and 10 to 3600 as hard values (because we can).

Note, this is not a real simulation of the light path through the lens.
The ideal solution would be this:

Thanks Brecht for the fix, suggestions and code review.
Kudos for the dome community for keeping me stimulated on the topic since 2009 ;)
Patch partly implemented during lab time at VisGraf, IMPA - Rio de Janeiro.
Submitted by: Justin Dailey (dail)
Patch allows the current line (or selected lines) to be moved up and down with
Ctrl+Shift+Up and Ctrl+Shift+Down. Has undo/redo support and operators in python
menu.
All operators which changes tracking data now just tags dopsheet as outdated,
actual re-calculaiton of happens only when this information is actually needed
(like on dopesheet draw).
This makes things a bit faster when there's no dopesheet visible in current
screen and also makes it much easier to update dopesheet using dependency
graph.
Also renamed dopesheet_sort_order to dopesheet_sort_method in rna and internal
stuff which makes much more sense and also correlated with naming in
file browser.
Supported sorting by name, longest tracked segment and total tracked frames.
Internally tracks are stored in Tracking datablock, but sort order is
a clip editor space property and sorting happens on clip editor draw.
If there's no dopesheet opened with different sort orders it's not
a problem due to re-sorting wouldn't happen.
Also fixed draw issue of tracked segments introduced in previous commit.
