66918b3add A bunch of fun stuff now possible because of new pointcache code:
* Baked normal particles can now use the "Path" visualization.
* Path "max length" & "abs length" are now history:
	- New option to set path start & end times + random variation to length.
	- Much more flexible (and calculated better) than previous options.
	- This works with parents, children, hair & normal particles unlike old length option.
	- Only known issue for now is that children from faces don't get calculated correctly when using path start time.
* New option "trails" for "halo", "line" and "billboard" visualizations:
	- Draws user controllable number of particle instances along particles path backwards from current position.
	- Works with children too for cool/weird visualizations that weren't possible before.
* Normal particle children's velocities are now approximated better when needed so that "line" visualization trails will look nice.
* New particle instance modifier options:
	- "path"-option works better and has controllable (max)position along path (with random variation possible).
	- "keep shape"-option for hair, keyed, or baked particles allows to place the instances to a single point (with random variation possible) along particle path.
	- "axis" option to make rotation handling better (still not perfect, but will have to do for now).

Some fixes & cleanup done along the way:
* Random path length didn't work for non-child particles.
* Cached & unborn particles weren't reset to emit locations.
* Particle numbers weren't drawn in the correct place.
* Setting proper render & draw visualizations was lost somewhere when initializing new particle settings.
* Changing child mode wasn't working correctly.
* Some cleanup & modularization of particle child effector code and particle drawing & rendering code.
* Object & group visualizations didn't work.
* Child simplification didn't work.

912c2f440b Pointcache refresh part 2
* Based on what happens during simulation the cache is marked (also in cache panel, this could possibly be extended to 3d view as well) as:
	- exact (not marked)
	- outdated (simulation is not done completely with current settings)
	- non-exact (frames were skipped during simulation)

* The parameter "cache step" effects the number of frames between saved cache frames.
	- This can save a lot of memory (or disk space) if absolutely frame accurate simulation is not required.
	- Speeds up the "quick caching" very much.
	- Frames between cached frames are interpolated from the cached frames.
	- Current default value of 10 frames works nicely with up/down-arrows (skip 10 frames forwards/backwards on timeline), but can be changed if wanted.

* The caching can work in normal or "quick" mode:
	[Normal cache]
	- Basic: Calculate what even happens (settings change, big frame steps etc.) and cache results, if possible try to use "cache step" when saving cache frames.
	- Becomes non-exact: After larger than 1 frame steps.
	- Becomes outdated: After any change effecting the simulation other than frame steps.
	- Pros/cons: Freedom of doing anything and playing with particles, but exact results have to calculated from the beginning.

	[Quick cache]
	- Basic: Calculate simulation up to current frame automatically on changes with cache step sized jumps in simulation. With multiple "quick cached" simulations the smallest cache step is used.
	- Becomes non-exact: Always from frame 1 (unless cache step = 1).
	- Becomes outdated: Never.
	- Pros/cons: Not very accurate, but super fast!
	- Todo: Transform of any animated (non-autokeyed) object is locked! Probably needs some tinkering with anim sys overrides.

* The simulation can be run forwards or backwards even if it's cache is outdated or non-exact, the following rules apply in these situations:
	- step forwards (to unknown) -> simulate from last exact frame, store result
	- step backwards (to known) -> result is interpolated from existing frames, store result, clear cache forwards if current frame is after last exact frame

* "Calculate to current frame" runs the simulation from start to current frame with a frame steps of 1.
	- Baking does the same, but runs the simulation all the way to the end of simulation.
	- Rendering does this automatically if the simulation is outdated of non-exact, so all rendered simulations will always be updated and exact.
	
* Every cache panel also holds buttons to "Bake all dynamics", "Free all dynamics" and "Update all dynamics to current frame".

* Cloth simulation supports the new cache too.

8ead648fd1 Spring Cleaning
* removed radiosity render code, DNA and RNA (left in radio render pass options), we'll get GI to replace this probably, better allow baking to vertex colors for people who used this.
* removed deprecated solid physics library, sumo integrations and qhull, a dependency
* removed ODE, was no longer being build or supported
* remove BEOS and AMIGA defines and references in Makefiles.
2009-06-21 16:18:38 +00:00
6b15024f4a Pointcache refresh part 1:
* Particles support larger than 1 frame changes, bigger frame changes can result in inaccurate results, but it's super fast and you get a nice feeling of how the particles behave!
* "Cache to current frame" button calculates the exact result of particles at current frame.
* Current state of cache can be protected by making it a bake.
* Cache is now in memory by default, disk cache is an option.
* Only "viewport %" number of particles are calculated and cached in viewport, baking and rendering calculate all particles.
* Info on cached frames and memory usage given in ui.
* Support for exact "autocaching" of changes and large frame changes(disabled for now until exact place in event system is decided)
* "Continue physics" is probably deprecated after this and should be removed once sb & cloth use the new cache code.

Todo:
* Make softbody & cloth use the new cache things.

Other changes:
* Some cleanup of particle buttons.

2d40b8d56f 2.5
Added SpaceLogic, to restore the old logic buttons into.
In future it can be used for a more advanced logic editor, with
states, behaviour, whatever. We'll see!

This commit only adds the backend for new space. Committed this
now as reference for when we need another space type. It's still
not well plugin-able (dynamic space types), but my idea is to just
have a new SpacePlugIn for this, with a neat small API to define
all relevant callbacks.

Also note the icon for the spacetype is wrong still.

ca12954e9f == Sequencer ==
Big proxy fix (addressing hopefully most complaints on mailing list and 
in tracker)
* proxy render settings are now independent of render size settings.
  That means: which proxy size is used, is controlled by two parameters
  now: the proxy size of the files, can be controlled with additional
  buttons within the proxy panels. What is shown in a specific preview
  window depends on the header settings of the preview panel.
  So: proxies are _only_ used in those windows, that are switched to a
  specific proxy resolution.
* output rendering is always done _without_ proxies.
* proxy generation now shows a waitcursor with numbers.
  (closing Bug: [#18909] Building Proxies doesn't give any feedback
  which was rather a feature request, since the problem mentioned there
  was always the case :) )

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
  a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
  not needed anymore.
  * Fix "duplicate strip" always increase the user count for ipo.
  * IPO pinning on sequencer strips was lost during Undo.

eecf7722b6 UI Buttons:
* Context now allows pinning a datablock, independent of
  selection.
* Initial ID browse buttons for most buttons tabs.
* Browsing from world to texture now displays world textures
  again, but is a bit of a hack, not sure there is a right
  way to do this.
* There's a button to switch between active materials and
  textures now, only temporary though.
* There's some code to put context part in own region,
  disabled still because it doesn't work that well yet.

580e69b365 Patch/Bugfix so wind noise got controlable seed and therefore redoable cloth sims - bug reported by istvan 2009-06-06 21:49:00 +00:00
880c43ad5a First new particle code:
-Many things not yet working properly :)
-Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome.
-Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types.
-Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more.
-Boid physics buttons are still missing as I'm currently redoing the whole boids code.
-Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.

5587e9bd09 UI:
* First step for buttons context browsing, read-only still.
* Drawn in a panel now, though this should become a separate region.
* Path of the context is constructed as an array of RNA pointers and

ea94f8ab8a == Sequencer ==
This adds custom proxy file storage to the sequencer.
Reasoning: sometimes low resolution versions are already available as a
seperate file built by the capture application.
So there is no real reason to make blender build it's own seperate proxy.

This also somewhat fixes (aehm works around :) )
[#13632] Creating Proxy Takes Over Process, Should be Background

Since now you can just fire up ffmpeg to build your proxies in the background.
(You could have done before and build a directory of jpeg files, but then you
would have to rename all the files since otherwise things are off by one...)

83bb096f24 + renamed pad3 to m_contactProcessingThreshold (thanks Campbell Barton/ideasman for confirming it is ok to rename it)
+ fixed Python method, PyArg_ParseTuple already checks for errors, no returning of NULL, thanks Campbell too)
+ added linear/angular spring for each of the 6DOFs of a generic 6dof constraint.  This makes the generic 6dof constraint very versatile.

eb8c5f3272 Set default constraint solver mode more compatible to Blender 2.48 settings, this fixes rigid body stacking in this blend file:
http://blenderartists.org/forum/showpost.php?p=1382653&postcount=102

(todo: expose this setting in World setting GUI)

Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.
2009-05-23 22:35:47 +00:00
036ebc5523 BGE: GUI control over frame rate, logic rate, physics rate and physics subrate.
Four new buttons in World settings to control frame rate:
fps:  Nominal frame rate in frame per second.
      Also sets the physics timestep = 1/fps
phys: Maximum number of physics timestep per game frame in case
      the actual fps is less than nominal. This allows the 
      physics to keep up with real time even if the graphics slows
      down the game.
sub:  Fixed number of simulation substeps per physic timestep.
      Improves the precision of the physics simulation. Useful for
      fast moving objects for example.
log:  Maximum number of logic steps per game frame in case the 
      actual fps is less than nominal. This allows the logic
      system to follow the physics simulation. 
      Upper bound = phys 
      (setting the value higher than phys has no effect).
      On games with heavy logic system, it is useful to set this
      value to 1, to keep logic time under control.

All these values were already accessible from Python except phys:

GameLogic.getMaxPhysicsFrame():
	Gets the maximum number of physics frame per render frame.

GameLogic.setMaxPhysicsFrame(phys):
	Sets the maximum number of physics timestep that are executed per render frame.
	Higher value allows physics to keep up with realtime even if graphics slows down the game.
	Physics timestep is fixed and equal to 1/tickrate (see setLogicTicRate)
	maxphysics/ticrate is the maximum delay of the renderer that physics can compensate.
      phys: integer

06a7155b68 BGE: user control to compound shape and setParent.
Compound shape control
======================
1) GUI control
It is now possible to control which child shape is added to 
a parent compound shape in the Physics buttons. The "Compound"
shape button becomes "Add to parent" on child objects and
determines whether the child shape is to be added to the top
parent compound shape when the game is stated.

Notes: * "Compound" is only available to top parent objects
         (objects without parent).
       * Nesting of compound shape is not possible: a child
         object with "Add to parent" button set will be added
         to the top parent compound shape, regardless of its
         position in the parent-child hierarchy and even if its
         immediate parent doesn't have the "Add to parent" button set.

2) runtime control
It is now possible to control the compound shape at runtime:
The SetParent actuator has a new "Compound" button that indicates
whether the object shape should be added to the compound shape
of the parent object, provided the parent has a compound shape
of course. If not, the object retain it's individual state
while parented.
Similarly, the KX_GameObject.setParent() python function has
a new compound parameter.

Notes: * When an object is dynamically added to a compound 
         shape, it looses temporarily all its physics capability
         to the benefit of the parent: it cannot register collisions
         and the characteristics of its shape are lost (ghost, sensor,
         dynamic, etc.). 
       * Nested compound shape is not supported: if the object
         being parented is already a compound shape, it is not
         added to the compound parent (as if the Compound option 
         was not set in the actuator or the setParent function).
       * To ensure compatibility with old blend files, the Blender
         subversion is changed to 2.48.5 and the old blend files
         are automatically converted to match the old behavior: 
         all children of a Compound object will have the "Add to
         parent" button set automatically.

Child ghost control
===================
It is now possible to control if an object should becomes ghost
or solid when parented. This is only applicable if the object
is not added to the parent compound shape (see above).
A new "Ghost" button is available on the SetParent actuator to 
that effect. Similarly the KX_GameObject.setParent() python function
has a new compound parameter.

Notes: * This option is not applicable to sensor objects: they stay
         ghost all the time.
       * Make sure the child object does not enter in collision with
         the parent shape when the Ghost option if off and the parent is
         dynamic: the collision creates a reaction force but the parent
         cannot escape the child, so the force builds up and produces
         eratic movements.
       * The collision capability of an ordinary object (dynamic or static)
         is limited when it is parented: it becomes automatically static
         and can only detect dynamic and sensor objects.
       * A sensor object retain its full collision capability when parented:
         it can detect static and dynamic object.

Python control
==============
KX_GameObject.setParent(parent,compound,ghost):
	Sets this object's parent. 
	Control the shape status with the optional compound and ghost parameters:
	compound=1: the object shape should be added to the parent compound shape (default)
	compound=0: the object should keep its individual shape. 
	In that case you can control if it should be ghost or not:
	ghost=1 if the object should be made ghost while parented (default)
	ghost=0 if the object should be solid while parented 
	Note: if the object type is sensor, it stays ghost regardless of ghost parameter
		
	parent: KX_GameObject reference or string (object name w/o OB prefix)

* Deprecated MA_HALO flag in favor of this.
2009-05-20 13:34:04 +00:00
40ae17d2f6 UI
* Fix buttons jumping around when resizing and zoom. Part of this was
  adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
  rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels.  V2D_LOCKOFS_X/Y is
  now taken into account in more places in the view2d code, to avoid
  zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).

* View3D/Graph/Image editors now use the same PanelType system as the
  buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.

* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
  object instead.
* Fix autotexspace -> auto_texspace in py script.

07fc2aa526 BGE #18665: Servo control and relative motion
Servo control motion actuator did not work as expected when the object
is moving on a moving platform. 

This patch introduces a new Ref field in the servo motion actuator
to set a reference object for the velocity calculation.
You can set the object during the game using the actuator "reference"
attribute; use an object name or an object reference.

The servo controller takes into account the angular velocity of the
reference object to compute the relative local velocity.

9ce8a67690 BGE Dome: removing of size option and adding tilt option.
- Size adjustments can be accomplished with warp mesh data now. So we get a free spot in the GUI for a tilt option.

- Tilt option to tilt the camera (for planetarium domes).
Angle is in degree from -180 to +180. It's needed for planetarium domes (as this one http://domejunky.blogspot.com/2009/05/dome-corrected-bge.html ).

- This is the last commit regarding dome code I expected to 2.49. I consider this feature full implemented now. (working on docs now)

2e93dc4037 F-Curve Modifiers: Time-Modifying F-Modifiers Cleanup
Time-Modifying F-Curve Modifiers now get special callbacks to allow them to specify what frame they need to be evaluated on, instead of forcing a re-evaluation of the preceeding curve + modifier-stack. This should be more robust than the old way in general.

It still remains to be seen if some tweaks to this are still needed, as the full consequences of the propogation of modified time-spaces have yet to be fully explored. 

For now though, evaluation works by finding the last modifier on the stack which modifies time, and asks it what time it modifies the given time to. This modified time is used to evaluate the F-Curve data only. The modifier stack gets evaluated using the original time instead.

9b82d1474f 2.5
Summary of ain features:
- Themes and Styles are now editable.
- CTRL+U "Save user defaults" now goes to new .B25.blend, so you
  can use 2.4x and 2.5x next to each other. If B25 doesn't exist, it
  reads the regular .B.blend
- Press Tkey in 3d window for (unfinished) toolbar WIP. It now only
  shows the last operator, if appropriate.
  Nkey properties moved to the other side.

A lot of work was done on removing old themes for good and properly
getting it work with the 2.5 region system. Here's some notes;

- Buttons now all have a complete set of colors, based on button classifications
  (See outliner -> user prefs -> Interface
- Theme colors have been extended with basic colors for region types. 
  Currently colors are defined for Window, Header, List/Channels and
  for Button/Tool views. 
  The screen manager handles this btw, so a TH_BACK will always pick the
  right backdrop color.
- Menu backdrops are in in Button theme colors. Floating Panels will be in
  the per-space type Themes.
- Styles were added in RNA too, but only for the font settings now.
  Only Panel font, widget font and widget-label work now. The 'group label'
  will be for templates mostly.
  Style settings will be expanded with spacing defaults, label conventions, 
  etc.
- Label text colors are stored in per-space Theme too, to make sure they fit.
  Same goes for Panel title color.

Note that 'shadow' for fonts can conflict with text colors; shadow color is
currently stored in Style... shadow code needs a bit of work still.

b22819f686 Bugfix #18039
Armature modifier didn't set amd->prevCos temp variable to NULL 
after freeing. Saving this in file will cause error or crash on
reading. Quite weird how it survived so long?

a82a6bedc5 Fix for bug #17457. This bug relates to files that have missing multires vertex data.
The fix is, if the file was saved on the highest multires level, then mesh contains a copy of the vertices anyway, and we can just copy it back into multires.

Otherwise, multires is removed from the mesh to avoid a crash.

74b12d1d6d 2.5
Patch from Joshua, converting Grease Pencil to 2.5.
All GP data now is an ID block, allowing re-use, link and append.
For better contextual control within 2.5, these GP ID's will get
linked to actual data, like NodeTrees, Scenes, Images or Objects.
That will ensure Undo works, and opens up exciting new use cases
as well. :)

Patch note: on reading files, GPencils linked from editors will
get moved to the main library, using standard naming (indicating
where it was used), and with "Fake User" set. That way the user
can manually relink the pencils where appropriate.
We can check on just linking GP to some default, like 3d window
pencils to Scene? Nice to experiment with.

Notes for Joshua:
- for reading old GPencil, it has to use old code as well, meaning
  to tread data as "indirect data, within another ID".
- Saving ID data means the chunk in file BHead needs the ID_GD code,
  and not "DATA", which indicates 'indirect data'. That's the file
  format spec.
- I've added do_versions_gpencil_2_50(), feel free to further tweak
  things here, like linking things to scene or so.
- Formerly GPencil saved 2.50 files won't convert gpencil

0db7c68106 UI:
* Forgot to finish this code yesterday, dragging panels was
  broken. This is fixed and new panels are now inserted after
  the last added one, inbetween others rather than at the end.
