===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.

|
- remove recently added sphinx reference workaround.
- tested doxygen, correct some warnings, set tab width and added pymathutils group.
- added convenience target 'make doc_doxy'

|
|
- removed some unused functions.
- renamed vars to make more sense paint_vertex.c 'flags' --> 'lock_flags'
- some odd modifications were made in unrealted, commented code, copy these back from trunk.
- rename vertex_group_fix 'cp' property to 'accuracy'
- make style more consistant with trunk.
- remove 'Radish' comments.
|
|
Added a tool-tip to the "fix deforms" op.
Removed code markers:
"Radish"

They weren't & aren't meant to show ownership, they just help me navigate my related code.

"Started" putting in wp's circle select, but it isn't there yet.

ED_view3d_init_mats_rv3d was calling glMultMatrixf() which was mostly harmless but could also lead to confusing bugs (2 reported previously).
Looked into this and every call to ED_view3d_init_mats_rv3d except for object drawing, doesn't need this so made a second version of ED_view3d_init_mats_rv3d - ED_view3d_init_mats_rv3d_gl which does the matrix multiplication, remove confusing checks in selection code.
|
|
|
|
ED_view3d_to_m4. added doxygen docs.
|
|
|
|
rather then 2 floats.
|
|
coordinates.
some functions had vague names, I even ended up re-writing some of these functions by accident!
also added doxy comments.
* ED_view3d_win_to_3d (was window_to_3d)
* ED_view3d_win_to_delta (was window_to_3d_delta)
* ED_view3d_win_to_vector (was window_to_3d_vector / viewvector)
* ED_view3d_win_to_segment_clip (was viewline)
* ED_view3d_win_to_ray (was viewray)

also update python view function to match.
|

|

conversion), now works in ortho and perspective view, initgrabz() is no longer needs to be called first.
|
|
(without having the View3D too and checking its camera values), added struct member 'is_persp', set with the view matrix.
|
|
- camera object movement was missing a notifier
- auto perspective now works when rotating the view.
- shift+b now zooms.
|
|
- follow rotate/pan/zoom/dolly operators.
- auto-depth preference works.
- smooth view navigation supported.
- view selected, all & numpad operator work too.
TODO
- deal with camera transform locked axis
- find a way to move/zoom the frame while the camera is locked (if it turns out to be a problem).
|
|
rename v3d functions
* view3d_to_ob -> ED_view3d_to_object
* view3d_apply_ob -> ED_view3d_from_object
* view3d_apply_mat4 -> ED_view3d_from_m4
Changed ED_view3d_to_object() not to temp modify the view rotation and don't overwrite the objects recalc.

mouse coords would with cont. grab would wrap at short.
use mouse coords as int rather then short.
this problem still happens on linux because of XTranslateCoordinates
|
|
also fix for mistake with rendering stars from previous commit.
|
|
gui (grayed out)
When in quad split view, operators that only apply to the unlocked region can now be accessed from menus and when the mouse is over a locked view.
Applied to:
- VIEW3D_OT_object_as_camera
- VIEW3D_OT_view_persportho
- VIEW3D_OT_view_orbit
- VIEW3D_OT_viewnumpad
|
|
- added notes to release todo's.
- renamed view3d view transform matching functions.
- added assert in edge split modifier to make a certain bug easier to spot.
|
|
- allow RegionView3D.view_matrix to be set.
- RegionView3D.view_rotation was inverted.
- add C function view3d_settings_from_mat()
note, intentionally removed NULL checks, double checked this is ok with callers.

bpy.ops.mesh.dupli_extrude_cursor() ) 2
Ctrl+Click on mesh or curve view was using the selected points location or the cursors.
if either of these was behind the view it would add the point at (0, 0, 0).
now fallback to the view orbit pivot, added this option as an argument to view3d_get_view_aligned_coordinate().
|
|
view3d_get_view_aligned_coordinate() could modify the event->mval.
|
|
perspective view.
|
|
workaround for view3d datamask not being correct on opengl render.
|
|
The bug is caused by a fix for [#22111], commits r29356, r28545.
exiting localview would set the rv3d->view but use the original rv3d->viewquat.
|
|
we cant ensure that a requested buffer can be allocated so report opengl errors when failing to allocate the buffer (rather then printing to console).
this is common enough and generic error isn't too helpful to users.
|
|

to curves.
added new functions
- view_autodist_depth_segment()
- plot_line_v2v2i(), which takes a callback and plots x/y points.

Sketching Sessions.
Fix for secondary issue noted in this bug report. Some of the code for
the fancy 3d view sketching options needed to be moved around so that
there is a clearer "paint/sketch session" and "stroke" separation
between various stages. There's still some more stuff that needs to be
done here before I think it's totally cleaned up.

Since 2.5x blender has been using CD_MASK_BAREMESH for updating objects since object_handle_update() no longer has access to G.curscreen to calculate the mask from viewports.
The problem with this is after an initial calculation, CD_MASK_MTFACE may be required on draw, so it would recalculate the modifier stack multiple times per frame.
One case which caused this is armature animated mesh with texface in a dupligroup.
Fix this by having customdata_mask member in the scene, this isn't great design but at least fixes the bug and only changes a few files.

- glReadPixels() was running to get the depth on each pixel, this works fine one some cards but was locking up on OSX.
- Replace glReadPixels() call with a single call to view3d_update_depths() right after view3d_validate_backbuf(), so the depths are only read once.
- Unrelated to the changes above, but should improve performance: view3d_validate_backbuf() was being called on every redraw while combing, now only call once when combing starts.
|
|
- Home or Numpad Period with smoothview disabled were not syncing up the other views.
- Disabling clip only disabled clip syncing but left clip enabled for all views.
- Clip was being calculated for every update even when not enabled.
- The perspective view was being used to copy settings from when changing box & clip settings, resetting the distance each time. Now use one of the aligned views instead.
|
|
|
|
intentionally ignores shift.
|
|
The problem is the opensource nvidia nouveau drivers are slow running glReadPixels(), was hanging on memcpy().
However for autodepth its not needed to update the entire 3D view depths, so added view3d_update_depths_rect() to get the depths for a smaller area.
|
|
accept the imbuf flag so they can get the float buffer from opengl directly.
|
|
cursor mode
also made drawing in camera view stick to the camera border (belated durian request),
useful for animation review without worrying about screensize moving the overlay about.
|
|
headers, better include inline with the C files that need them
