This patch add SPH (Smoothed Particle Hydrodynamics)fluid dynamics to the
blender particle system. SPH is an boundless Lagrangian interpolation
technique to solve the fluid motion equations.
From liquids to sand, goo and gases could be simulated using the particle
system.
It features internal viscosity, a double density relaxation that accounts
for surface tension effects, static internal springs for plastic fluids,
and buoyancy for gases.
---------------------------------------
This is a commit of the core fluid physics. Raul will work on proper
documentation soon and more features such as surface extraction from
the particle point cloud and increasing stability by sub-frame calculations
later.
I removed 3D flag checking for DL_POLY displists in nurbs-to-mesh conversion
function -- DL_POLY displist should be always converted to edge loop.
DL_POLY which should be converted to something else is odd i think.
This commit also fixes trouble cyclic surface curve to mesh conversion problem.
dupliverts. The flag mode & OB_MODE_EDIT only indicates that
this object is being edited by the user, not if the mesh is
in editmode or not, it should check for the existence of
me->edit_mesh. Also corrected two other places for this.
- Rename option and flag to something more sane
- Add property to manipulator operator and set true by default
Confirm on Release can now be forced true or false per operator, in which case it won't use the default value (the user preference).
Add hidden property to be able to force confirm on release (drag immediately is a silly name) on or off.
Streamline method for adding common properties to transform operators.
experiment and turn out to work poorly because it does not preserve
rotations, so I've just removed the option now. Alternative is to use
a solidify modifier on the cage mesh, which will usually give better
results.
Font kerning needs to be set in order to get accurate results out of BLF_width().
Would be nice if this was more automatic, I've added it to a few other places that
seem like they need this though it's a little unclear due to the globals etc. Also
some other minor tweaks when editing text fields.
This replaces the screen-aligned bitmap text drawing with wireframe x/y/z as
part of the empty axis openGL code. It's a lot faster in all situations that draw
empty axes to screen - including posing armatures with axes on (5fps vs 40fps
on tracker test file).
* Fixed the way the operator was checking for what the user wanted when using the operator
* Added a few specific defines to a copy of the gesture border modal keymap (added one for zooming only) labelled 'In' and 'Out' which make this more useful than being hacked to use select and deselect
This commit fixes reports #21638 and #21818, which were both also Durian feature requests.
Cbanges:
* Added new default setting for the type of handles created when creating keyframes. This can be found in the user-preferences, and is used whenever existing keyframes aren't being overwritten (instead of the value being always taken from the keyframes either side, #21638).
* When keyframing over existing keyframes, only the values will be changed. The handles will be offset by the same amount that the value of the keyframe changed, though how well this works in practice still needs to be tested more thoroughly (#21818, already fixed earlier, but this commit is the full fix).
* When 'free' handles are added by default, they are offset to be +/- 1 frame on either side of the keyframe so that it is obvious that they can be moved. However, they just take the same value of the keyframe since this is easiest.
* Properly initialising handle colour defaults for 3D-View and Graph Editor. Graph Editor's theme userprefs also show these settings now, though the layout is really quick hack-style.
* Bugfix for missing high res calculation when low res cache was already there
* Bugfix for loading file with smoke but tfor the first "round" of alt-a nothing happened. Now the smoke gets calculated on file load, too.
Curve sampling minimum 'sampling frequency' for display could get too low causing a hang (with really-slow convergence). Clamping with a coarses limit now.
* Fixed all the dangerous code added in 27907. Using the code there, scripters could corrupt animation files in ways which would render them useless, with channels not appearing in any animation editors, and others not getting evaluated at all.
* Partial fix of bug 21818, by disabling destructive replacement of keyframes. Will followup this commit with a more comprehensive commit which gets rid of the rest of the problems, by incorporating some requests from Durian team.
* Fixed problems with users being able to see+edit the name of the active Keying Set in the Scene buttons. There is still a bug though with the list widget given how the indices are now interpreted...
