- optionally display the histogram as lines (not filled areas).
- expand the enum for faster access.
- keep the sample line displayed after doing the line sample (running again clears).
One side of change is related on making code easier to follow, due it started
being quite messy because of all in-lined mode/view checks. Now there's a bit
of code duplication, but it's much easier to see what's going on there.
Another side of patch is related on re-arranging elements in header in a way
that follows rule "depending elements are placed after elements they depends on".
This might be a bit against mostly-used-based elements placement, but now it's
much easier to figure out where to add new option. Also it fits better other
blender's areas such as image editor header, i.e.
Now it's indicates at which scene frame number movie clip starts playing back.
This this setting is still belongs to clip datavlock and used by all users of
clip such as movie compositor nodes, constraints and so.
After long discussion and thoughts about this it was decided that this would
match image's current behavior (which initially seen a bit crappy), but that's
actually allows:
- Keep semantics of start frame in image and clip datablocks in sync
- Allows to support features like support of loading image sequences
with crappy numbers in suffix which doesn't fit long int.
- Allows to eliminate extra boolean checkbox to control such kind of offset.
Hopefully from pipeline POV it wouldn't hurt because idea of having this things
implemented in original way was working only if sequence before processing
started naming form 001.
Self collision vertex groups enable artists to exclude selected vertices from getting involved in self collisions. This speeds simulations and it also resolves some self collision issues.
Number of start frame in opened image sequence used to be distinguished automatically
in a way that file name used on open would be displayed at scene frame #1.
But sometimes it's useful to have it manually configurable (like in cases when you're
processing image sequence and replacing clip's filepath to postprocessed image sequence
and want new clip to show at the same frame range as it was rendered from).
Added Custom Start Frame flag to movie clip (could be accessed from Footage panel in
clip editor) and Start Frame which means number of frame from sequence which would
be displayed at scene frame #1.
For example if you've got clip pointing to file render_00100.png and Start Frame of 100
this file would be displayed at scene frame #1, if Start Frame is 1 then this image
would be displayed at scene frame #100,
========================
The linear and angular thresholds set the speed limit (in m/s) and rotation limit (in rad/s)
under which a rigid body will go to sleep (stop moving) if it stays below the limits for a
time equal or longer than the deactivation time (sleeping is disabled is deactivation time is
set to 0).
These settings help reducing the processing spent on Physics during the game.
Previously they were only accessible from python but not working because of a bug.
Now the python functions are working and the settings are available in the Physics panel
of the World settings when using the Blender Game render engine.
Python API:
import PhysicsConstraints
PhysicsConstraints.setDeactivationLinearTreshold(float)
PhysicsConstraints.setDeactivationAngularTreshold(float)
===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.
"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.
See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.
Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.
