===========================
- Distortion/undistortion were accidentally swapped in both of grease
pencil calibration and grid.
This was fixed but distortion coefficients should be re-adjusted.
There are some issues with high distortion coefficients but it
came from libmv and until it'll be fixed there nothing really
can be done here.
- Fixed displayed aspect ratio for muted footage when pixel/display
aspect ratio is differ from 1.0 or proxy size is not Full Render,
- Added c-api for image distortion/undistortion, Not used yet.
===========================
- Option to hide grease pencil (Display -> Grease Pencil).
- Added grease pencil controls to toolar.
- Fixed display issues when stroke contains one point only
and Manual Calibration is enabled.
===========================
Continue improving grease pencil for manual calibration:
- Fixed bug with local undo which was caused by not dropping
re-done nodes when pushing new undo node.
- Fixed bug with conversion grease pencil to bezier curve
(last point could be dropped away on such conversion).
- Added new mode: poly line drawing.
This mode allows to draw poly-line by clicking on
it's knots. In this mode user is allowed to pan/zoom
to new position before placing next knot.
Causing a flurry of refresh file prompts post-commit,
Confusing local diffs and causing merge conflicts,
Stating the obvious; redundant and useless...
We shall not miss thou, blasted expand $keywords$
===========================
Return non-blocking behavior to grease pencil sketch mode.
It is needed to implement more accurate line drawing based
on using mouse click on where line "knot" should be added
and allowing pan/zoom between such knots selection.
There are still issues with vertex paint/sculpt modes,
but they aren't critical -- just behavior could be
improved here.
Currently, grease pencil conflicts with such operators
as undo and set object mode which makes behavior totally
unpredictable and crash for some cases.
The only way to solve this proper is to ger rid of pointers
to data which can chage stored in operator custom data.
* kernel has shading nodes / textures disabled, amd/nvidia opencl
compilers choke on these, need to figure out how to avoid this
* works in cycles_test, not available as option in blender yet
* kernel compiles and runs with opencl 1.1 from intel/amd/nvidia
Adding a mono flag to mixdown non-mono sounds for 3D audio.
* Added mono sound loading.
* Bugfix: AUD_COMPARE_SPECS usage was wrong.
* Bugfix: JOS resampler = instead of ==.
* Bugfix: Change of a sound should apply settings in AUD_SequencerHandle.
* Bugfix: Memory leak when canceling open sound operator.
if vec.dot(vec) > some_distance*some_distance:
do_something()
might not be quite as obvious looking as:
if vec.length_squared > some_distance*some_distance:
do_something()
As to why you'd want to use length_squared over length is that length uses a square root, which isn't always necessary for simple distance checks (e.g., closest object, checks like the ones above, ect).
