===========================
- Corrected copyrights in my new files header.
- Added debug option to dump as PNG image content of search
areas tracking between which was failed.
- Removed internal tracking settings like pyramid level and
tolerance. Weren't useful neither for me nor for artists.
- Fixed bug in BKE_tracking_get_marker which could lead
to failure of getting marker for current frame when
there's marker for requested frame.
- Fixed bug with disappearing markers after tracking for
cases when marker was added at frame different from
tracking start frame and tracking start frame is
equal to tracking end frame.
- Stop tracking when no markers could be tracked.
- Changed marker selection rules:
* If marker isn't selected, all it's areas are getting
selected with mouse.
* If marker is selected and selection type doesn't have
"extend" mode (SHIFT isn't holded down) the nearest
to mouse cursor area would be selected. All the reast areas
would loose selection.
- Limit number of frames which would be used in "Track Markers"
operator. So now you could easily track along 10/20/etc frames.
- Change scene current frame after "Track Markers" operator.
- Implemented speed limitors. Now tracking could happen:
* As fast as possible
* With reatime speed (scene FPS)
* With half of realtime speed
* With quarter of realtime speed.
- Got rid of orig_user in MovieTrackingContext and user
in TrackMarkersJob. This prevents crashes when user
joins some space to SpaceClip from which tracking was started.
- Made keyframes on path bigger and do not draw keyframes for
non-selected markers.
TODO: need to get rid of storing main, scene and screen
in TrackMarkersJob. This is needed to set scene's
current frame after tracking (such behavior is comfortable
for artists) but this could lead to crash if scene is
getting removed when tracking job is running.
Render animation operator also stores scene and main,
so such solution could be fine for first time before
we've got something smarter.
===========================
Test tool: convert track to location fcurves for object in 3d world.
1 pixel on footage is equal to 1 Blender unit.
Added for testing only, could be removed any time -- real
parenting to markers/bundles are only under design now.
===========================
Refactored interface of movie clip editor:
- Remove all "modal" things like active tool and mode.
They aren't so useful as I thought when was starting
implementation of UI.
- Toolbar (T-panel) now contains tools only, no options/properties there.
- All properties are moved to properties panel (N-panel).
===========================
- libmv's sources would now be added to qtcreator project.
- Fixed compilation with blenderplayer enabled and cmake.
- Fixed bug when tracking was done from frame different from
initial marker's frame number.
- Implemented backwards tracking.
- Added option to draw track's path. Would be enabled by default
for new scenes. Could be enabled on "Display" panel for
files saved in previous version.
- Added operator to clean track path so it could be
easily tracked form scratch.
- Added hotkeys for tracking, backwards tracking and
cleaning track path (Ctrl-T, Ctrl-Shift-T and Alt-T).
- Fixed crash when setting clip as a footage.
- Small optimization when trying to track without
selected markers.
- add support for IDProp array slicing, but not resizing.
- rename array attribute type to typecode and use chars 'f', 'd', 'i' which match pythons array module. (was using int's which only have a meaning internally).
- rename function 'convert_to_pyobject' to 'to_dict' and 'to_list' for IDProp group and array types respectively.
- remove 'len' array attribute, calling len(array) is fine.
This patch adds anisotropic filtering of textures in the viewport and the BGE. The quality of the filtering is adjustable in the user preferences under System. For more information on anisotropic filtering:
http://en.wikipedia.org/wiki/Anisotropic_filtering
One current limitation of this setup (having the option a user preference) is it makes runtimes more troublesome. Runtimes don't have user preferences set, so for now the blender player defaults to 2x AF. Options will be added later to change this value (probably a command line option).
===========================
- Marker's preview panel is now avaliable with any
tool selected (except NONE).
- Fixed bug with marker's point going outside of pattern
when scaling pattern which isn't centered to marker's pos.
- Changed a bit pattern area image generation.
Now it shouldn't give artifacts with different kinds of
offsets caused because of float-?int conversions.
- Rollback code for generating flat buffer of search area
when tracking. It'll be more accurate with current position
calculation.
Will switch to BKE_tracking_acquire_search_imbuf when
backwards position calculation would be implemented.
- Added option to make markers thin. It's in Debug panel due
to this option was really useful for debugging preview image
but not sure it'll be useful for artists.
- Added "View Selected" operator (hotkey is numpad period).
Fits view to show all selection at the frame.
- Added option "Lock to Selection" which locks view
to show centered selection. Useful to visual markers
tracking during playback.
This option is on "Display" panel.
- fix python error when the object had an empty material slot
- initialize start frame from the current frame
- set frame range to 300000 max (which is blenders own maximum)
- mesh order was arbitrary, instead use selected -> active, removed invert option.
also fix for missing include in bpy_extras.view3d_utils
===========================
- itasc adopted for Eigen3 library.
It compiles well, but need deeper testing for regressions.
- Removed Eigen2 library.
- Added settings to tracker which could be changed from UI.
- Pattern area is now affects on tracker.
Currently libmv supports square patterns which are centered
to marker's position. Maximal pattern dimensions is sending
to libmv as pattern size. Would be changed when libmv would
support non-centered and non-square patterns.
- Fixed bug with syncing pattern's flags when tracking.
- Current frame in cache line became a bit more visible.
It's useful for me to when debugging.
- Changed behaviour of "Add Marekr" operator: not it's non-modal
and places marker on mouse position at click.
- Added macro "Add Marekr and Move" which is used to place
markers from toolbar button.
- Added some utility functions to get image buffer under search
and pattern area which also returns relative position of
marker center for this images.
Generated images are more "correct" from coords rounding
POV, but re-calculation of marker position back to
frame coords is more complicated and not implemented yet,
so old not very accurate logic is still used.
- Added preview widget with content of pattern area.
NOTE: files saved in previous versions of this branch could
easily crash on tracking. Use "Reset To Settings" button
from Tracking Settings before tracking selected markers
for such files.
TODO:
- Implement adjusting marker position from marker's
preview widget.
- We've got an idea of sliding marker after click before
releasing mouse button.
a) Enable the possibility to remove the "air bubble" around submerged collision object. This feature is enabled as standard for new files. The code was found in elbeem by nudelZ, coded and provided by Nils Thürey (thanks!)
b) Old baked files gets deleted if a new bake gets started (were overwritten before and resulted in weird old bake + new bake mixture) (idea by nudelZ)
* Sets up a particle system and an explode modifier.
* In "blend" mode requires two selected objects and creates "crossed keyed" particle systems between the objects for a simple blend effect where the first object explodes and then recombines as the second object.
* Also renamed the other quick effect operators as "Quick ..." to bring some consistency to the operators (also nice that now you can just write "quick" to the operator search and get all these operators).
===========================
- Added missed stub for blenderplayer, so it should
compile again fine.
- libmv is added to extern/.
Script for bundling needed subset of sourcses from
libmv repo is included there.
- Eigen3 is also added to extern/.
libmv depends on Eigen3 (which isnt't compatible with Eigen2
from API point of view). So both of versions are going to
be in worktree for time (until code which used Eigen2 would be
ported to Eigen3).
- Added some functions to libmv-capi, so some things from
this library could already be used.
- Added the very basic implementation of 2D tracking.
It should be treated as draft for tracking architecture
which probably would be cleaned up, changed or whatever else.
Current implementation was supposed to demonstrate that our
structures and understading is correct to interact with libmv easily.
===========================
- Disallow moving pattern/search area in way when marker position is
outside of pattern area.
- MoiveClip could be set as background for 3D view.
Added background source property to BGPic to switch between image
and movie. Movie is a bit more complicaated entity than clip (due to
displaying bundles, test objects and so) that's why i've sliptted
background into two sources.
- Added Layout.template_movieclip to display general clip settings.
Used in Footage panel of SpaceClip and background image properties
in 3d view.
- Display bundles in 3D view as spheres. Selection is synchronized to
markers associated with this bundle.
Bundle can't be selected in 3D view.
- Recoded internal DNA structures, RNA and operators to match libmv entities.
Tracking data now consists of Tracks, each tracks consists of markers
which are associated with frame number. Markers holds position only,
pattern and search areas settings are stored in track. Such settings should
be unified for all markers in track and marker should hold position and
frame number only.
added 'INTERNAL' operator flag so operators which are only meant to be called by other operators or internal use are not displayed to the user.
Currently only use this flag for the operator search toolbox, is ignored in debug mode.
=======================
Added option to baked named "Bake From Multires" which is avaliable for
normals baking and displacement baking.
If this option is enabled, then no additional hi-res meshes and render
structures would be created . This saves plenty of memory and meshes
with millions of faces could be successfully baked in few minutes.
Baking happens from highest level against viewport subdivision level,
so workflow is following:
- Set viewport level to level at which texture would be applied
during final rendering.
- Choose Displacement/Normals baking.
- Enable "Bake From Multires" option.
- You're ready to bake.
Displacement baker had aditional option named "Low Resolution Mesh".
This option is used to set if you want texture for realtime (games)
usage.
Internally it does the following:
- If it's disabled, displacement is calculated from subdivided
viewport level, so texture looks "smooth" (it's how default
baked works).
- If it's enabled, dispalcement is calculated against unsubdivided
viewport levels. This leads to "scales". This isn;t useful for
offline renders much, but very useful for creating game textures.
Special thanks to Morten Mikkelsen (aka sparky) for all mathematics
and other work he've done fr this patch!
- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
- name "Undo History"
- hotkey alt+ctrl+z (alt+apple+z for mac)
- works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
- for small windows or screens, popup menus now allow to display
all items, using internal scrolling
- works with a timer, scrolling 10 items per second when mouse
is over the top or bottom arrow
- if menu is too big to display, it now draws to top or bottom,
based on largest available space.
- also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
- widgets & headers now become bigger and smaller, to match
'dpi' font sizes. Works well to match UI to monitor size.
- note that icons can get fuzzy, we need better mipmaps for it
===========================
Implemented basic structures and operators for markers manipulaiton.
Markers contains:
- Position of marker at frame in unified 0..1 coordinates
- Relative positions of left-bottom and right-top corners of pattern area
- Relative positions of left-bottom and right-top corners of search area
- Selection flags
New operators:
- Create new maerker. It's a modal operator which creates markers
at mouse position when LMB is clicking.
- Delete selected markers.
- Select marker using RMB. Some parts of marker (point, patter, search)
could be deselected.
- Select markers using rectangular selection.
- Select markers using circle selection.
- Marker translation (G-key).
- Marker scaling (S-key).
UI changes:
- Added mode to space clip. Currently supported modes are:
* View mode
* Tracking mode
This was intended to separate different categories of tools,
so interface shouldn't be overheaded with plenty of tools
which aren't actually using in the same time.
- Created new panel when actiev tool is 'MARKER' and there's
active marker where positions could be adjusted in pixel space.
Internal changes:
- Splitted DNA/RNA movieclip files to make separation of
tracking data and movie data more clear. This could be useful
in the future when we'll want to support multiplie moies
for single camera tracking (to make tracking more accurate).
- Added new file in blenkernel, where all tracking-related function
would be stored. Not very much function here at this moment,
but in the future all stuff related on converting DNA to external
tracking data would be stored here.
