1fe5302cce Point Cache Refactoring
=======================

Caching and Baking:
- The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates.
- There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles.
- The cloth autoprotect feature was removed.
- The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries.
- The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions.
- PointCache struct was added to DNA and is automatically allocated for each physics type.
- Soft body now supports Bake Editing just like cloth.
- Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now.

Library Linking:
- Added some more warnings to prevent editing settings on library linked objects.
- Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked.
- Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh).

Physics UI:
- Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth.
- Tweaked field panel buttons to not jump around when changing options.
- Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable.
- I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers.
- Fixed modifier error drawing glitch.

Particles:
- Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() ..
- Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading.
- Make particle threads work with autothreads.

Continue Physics:
- The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache.
- This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics.

Todo:
- Point cache can get out of sync with and undo and changing a file without saving it.
- Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion.
- Menu item and/or buttons for Ctrl+B.
- A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested.
- The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

e7384c9dd2 Commit patch #8799: Realtime SetParent function in the BGE
This patch consists in new KX_GameObject::SetParent() and KX_GameObject::RemoveParent() functions to create and destroy parent relation during game. These functions are accessible through python and through a new actuator KX_ParentActuator. Function documentation in PyDoc.
The object keeps its orientation, position and scale when it is parented but will further rotate, move and scale with its parent from that point on. When the parent relation is broken, the object keeps the orientation, position and scale it had at that time.
The function has no effect if any of the X/Y/Z scale of the object or its new parent are below Epsilon.

49c65433cc Fix for bug: [#8117] Particles with fluid broken
-Handling of fluid particles was not coded at all
-Now things should work properly, but as fluid particles are not very familiar to me I'd appreciate some thorough testing

5fa576a89f UV Unwrap (lscm, project from view, cube etc) now default to correcting for the active images aspect ratio.
This is now default but can be disabled in the UV Calculation panel. At the moment its called "Image Aspect" but another name could be better.

af8c68ddc4 Cloth structure names update: Sorry about this commit, it will kill all your cloth settings in old files but I had to do it before release because naming convention was really bad in cloth (e.g. using SimulationSettings instead of ClothSimSettings in DNA). Same for some structure in CollisionModifier but with no sideeffects. 2008-03-20 18:28:40 +00:00

Bugfix #6543: Blender.Library.Load() could segfault if called more than once
with a library of different endian type.  In the process discovered an
invalid memory reference in other another function calling library_append().
Thanks to Brecht for the pointers on tracking this old bug down.

3bec4f5f87 my last commit to readfile.c crashes some files, must look further into this. 2008-03-14 09:46:53 +00:00
2c78254f96 line commented out with the orange merge is needed for library linking when linking in objects that indirectly point to groups that are already directly linked in. This has been a problem for many peach scenes. but saving and reloading made the objects appear. 2008-03-13 21:41:28 +00:00
4c6ff955ed quick fix for null check that crashed blender when reading some files. 2008-03-12 10:20:45 +00:00
0ec0f2a02f Add an option for saving/loading DPX with in log color space with
reference black, reference white and gamma.

Added 16 bit TIFF saving.

This needs more work to cleanup code and add 16 bit TIFF reading, but
committing it now so it can be tested.

b4e13ae575 Another big purge of warnings. (Main culprits this time were Campbell and Geoffrey):
* no newline at end of file (2-3)
* uninitialised vars (1)
* unused vars (1-2)
* assigning/comparing pointers and ints (numerous)
* etc.

08f306c81c Made python scripts save and load in the blend file so you can have the same scripts running when you open a blend file.
Also scripts will re-run on undo rather then closing.

This is done by saving and loading the name of the script or textblock of the 'Script' datablock, connected to the ScriptSpace. This way when there is a name but the script dosnt run.
Blender runs the script or text block if available.

4037ef7714 Fix for undo optimization commit, compiler error on msvc. 2008-03-05 17:51:35 +00:00
4f764637e6 Undo optimization: now big chunks of memory are not written as single
memory blocks anymore, but smaller fixed size blocks, so that diffing
can be more effective. For example helps in sculpt mode when making
only local changes to the mesh, previously it would copy the whole
MVert array for each undo step.

4165ae42cc == Sequencer ==
Fixed a bug with ibuf caching on startstill / endstill.

The new blend modes happened to force start and endstill to be rendered
over and over again. This could get very annoying especially on scene
strips.

We therefore now cache the original start or endstill ibuf seperately
and copy on demand.

905a2d374a Cloth: 1. Bugfix for possible memory leak reported by Kenneth Styrberg (via mailing list), 2. Bugfix for friction again, 3. Preset menu on GUI (thanks to help from nudelZ (#blendercoders), 4. Possibility to disable autoprotect cache, 5. Some cache bugs fixed, 6. Some speedup in generating cloth 2008-02-28 00:01:19 +00:00
931ac1cebd Bugfix: recent rollback of premul changes gave issues. The premul
flag bit was changed and not changed back, and the flag was moved
back from image user to image. This meant that files saved both
before and during the premul changes did not read premul settings
correct anymore.

Now it uses the old premul flag bit again, which also keeps forward
compatibility.

e601994b15 Fix for bug #8324: J-key render buffer switching had various issues.
One problem was that the previous render buffer was stored in the
render window or image window itself, which means that when closing
it, or switching from one to the other, things didn't work as expected.
Also in the image editor, color sampling the previous render buffer or
saving it didn't work correct.

f312611a92 =ID Property Bugfix=
There was an extraneous line causing ID property groups
to have the wrong length, causing crashes in code that
relied on it.

This commit both fixes that and adds a version check to
fix group lengths for older .blends.  The subversion
was incremented to 15 for this change.

0e233b3213 =Reversion of premul bugfix=
Reversion of premul bugfix, as it was apparently not
working all that well.

Note that this brings back the bug where the erase alpha
paint tool won't display correctly, since the UV image
editor just draws images in key alpha now.

ccac67d3ea Further work on the premul option for ton. This option
(which basically tells the renderer and compositor to expect a
key image) is now done at the image user level.

This does have some caveats, as image users don't always work
the way I thought they would/should (for example, the same image user
structure is apparently used in the uv image editor for all images,
which is kindof odd).

The UV image editor also now smartly detects if the premul option is
set and draws the image using key alpha, instead of premul

The subversion level was upped to convert the old premul flag, which was at
the image level, to the new one, which is at the image user level.

ef17600b5c Old particles didn't interpolate between keypoints at render time so regression test hairball.blend didn't render properly. Now all converted particle systems have path display and render steps set to 0 so that only the keypoints are used. 2008-02-17 15:46:03 +00:00
b12793fb4f Render Simplification
This adds a few settings to control global render quality, for faster
renders when tweaking lighting etc. The implementation is not so great,
and this should really be part of a proper render profile and preset
system. So for now it's a hidden Peach feature, enabled by setting rt
to 1. Before the next release, I'll either remove or improve it.

Settings are:

- Maximum subsurf level
- Child particles percentage
- Maximum shadow map samples
- AO and SSS quality factor

16514e3ddb * Merge of PyNodes to trunk. Finally!
See http://wiki.blender.org/index.php/BlenderDev/PyNodes and
  http://wiki.blender.org/index.php/BlenderDev/PyNodes/API
  For current documentation.

  Very very big thanks go to William Germano for fixing the memory issues left
  and for improving on the code.

  In the coming time documentation will be finalised and further stabilising
  of PyNodes is to be expected.

3a6a3d0389 == Sequencer ==
New feature: color balance aka 3-way-color-correction aka lift/gamma/gain 
on input (folded into byte -> float conversion, so _very_ fast in that case).
Interface is inspired from Rebel CC (but not as complete yet, you can't
choose white and black points right now).

Bugfix: clamp color seperated wave form display correctly.

eb9375fb56 Fix for indirectly linked libs being converted into direct linked libs. (tried to fix this before but didn't work).
fix_relpaths_library() needs to be called after loading libraries but not during recursive library load.

c931ceeaf7 last commit worked in test case but not in real world :/ - revert and will look further into it. 2008-01-31 22:53:31 +00:00
37f7826ee1 Fix for indirectly linked libraries.
When a.blend -> //../c.blend -> //d.blend
Blender would see d.blend as //d.blend which is wrong since that is relative to c.blend
This works, except when you make an indirectly linked group into a directly linked group. and then the incorrect path was saved into the blend file and the data not load up again (without copying it there or hex editing the path)

This loop makes all lib files relative to the blend you have open.
2008-01-31 21:19:40 +00:00
b18499fdf6 Speedup of filereading: when using large libraries (referenced data from
other blend files) lookups of data slowed down tremendously.
Added another bsearch for speedup. Makes a difference here (200+ MB files)!

fd9db17021 == Sequencer ==
This fixes several crashes with the new tstripdata_start/endstill.
dupli_seq was cleaned up as well as add_scene_strip (moved to a 
seperate function)

New features: 
* opacity can be used in replace blend mode
* the scene within in a scene track can be changed now within the panel

Also:
* [#7842] Note: setCodec in FormatTab disappeared...
  should be fixed by this. (Not a big change, so I just commit and see :)

264c8d94f9 == Limit Distance Constraint ==
Added a new constraint, "Limit Distance". This constraint defines a 'virtual sphere' around the target which the owner can be made to stay inside, outside, or on the surface of it. 

This constraint is best used when applied using the Ctrl-Alt-C hotkey, as the radius is set correctly that way. 
One usage, is to prevent the target of an IK-chain from straying away from the chain. Care should be taken to not use a member of the IK-chain as the target though.

Description of Variables:
* 'Dist' - Radius of virtual sphere
* 'R' - Click on this to recalculate the 'Dist' value (note: like the 'R' button in the StretchTo constraint, this is currently buggy)
' Mode' - This menu gives different options for how the limiting sphere should act. The mode names are self explanatory.
* 'Soft' and 'SoftDistance' - currently not functional (so settings are hidden). These are used to define a smaller radius around the sphere of influence where a non-linear relationship between input and resulting locations occurs to prevent the owner 'crashing' into the sphere.
2008-01-25 11:23:36 +00:00
cd137f2898 == Bone Groups ==
I'm committing some work-in-progress code for "bone groups" now, as I there have been are some major bugs caused by the timeoffset stuff (some of my test files were not loading, and other files were showing all sorts of weird problems). 

Anyway, in this commit, the following things for "bone groups" have been done:
* Bone groups are stored per armature (internally, this is per bPose block)
* Added controls for editing bone-groups per armature - "add", "remove", "rename". These can be found in the "Links and Materials" panel in PoseMode, beside the settings for PoseLib.
* Reorganised buttons for editing selected bones in PoseMode. I've replaced the "dist" and "weight" buttons (they existed in EditMode anyway) with a menu to choose the bone-group and the custom-shape-ob field. In the place of the old custom-shape-ob field, I've restored the "Hide" button. This might break muscle-memory a bit, but there isn't a lot of space to play with there.

Some stuff I'd been originally planning to do before committing:
* When adding keyframes for bones, an action-group with the same name as the bone's group will be added to the action, and the action-channel will be made a member of that. 
* New action/bone groups have unique names (renaming/adding new should check if name exists before assigning it)
* There's a setting under Bone-Groups stuff which sets which custom-colour set is used to colour that group's bones. Currently, this is non-functional, as the necessary drawing code for armatures is not in place yet.
2008-01-20 02:55:35 +00:00
afc53a1eba Bugfix: particle settings didn't automatically link in associated
objects or groups.
2008-01-18 14:30:26 +00:00
9d13e08331 bugfix didnt get committed somehow, appending a group assumed any indirectly linked objects were apart of the appended groups and the objects added to the scene.
Now there are recursive dupli's this is no longer true. so need to check the append flag.
2008-01-18 11:51:46 +00:00
44c31bb045 == Action Editor - Groups for Action Channels (Peach Request) ==
Now, you can assign Action Channels to named (folder-like) groups, which help to organise the channels (important for more complex rigs). These are collapsible, can be "protected", and show a "summary" of the keyframes in the channels the Group contains. They are drawn as bright-green (active) or a darker shade of green (not active) channels.

* Each Action has its own set of Groups. 
* An Action-Channel can only occur in one Group at a time. It can also not occur in any group.
* Action-Channels can be moved between Groups
* Groups + grouped-channels always occur BEFORE un-grouped channels

Important Hotkeys:
* Shift-G  :  Adds the selected Action-Channels to the Active Group. This will create a new group if need be
* Ctrl-Shift-G : Always adds a new group, and adds the selected Action-Channels to it
* Alt-G : Removes selected Action-Channels from their groups
* Ctrl-Shift-Alt-G : (Note: this will be removed soon) This is a simple debugging-hotkey I added, which just prints a list of the groups, channels, and their addresses...
* NKey / Ctrl-LMB: While hovering over the name of a group, this shows a popup like for other channels, which allows the editing of the channel's name, etc.


Assorted Notes:
* Some tools may not work yet with this (Ctrl Numpad+/- for example)
* Fixed some bugs in various places in Action Editor code
* Added theme colours for group channels
* The nomenclature of these tools may change in future when a better alternative is found
* The ability to auto-assign action-channels to groups when they are keyframed will be coming up shortly

8cdfe865ec Approximate Ambient Occlusion
=============================

A new approximate ambient occlusion method has been added, next to the
existing one based on raytracing. This method is specifically targetted
at use in animations, since it is inherently noise free, and so will
not flicker across frames.

http://www.blender.org/development/current-projects/changes-since-244/approximate-ambient-occlusion/
http://peach.blender.org/index.php/approximate-ambient-occlusion/

Further improvements are still needed, but it can be tested already. There
are still a number of known issues:

- Bias errors on backfaces.
- For performance, instanced object do not occlude currently.
- Sky textures don't work well, the derivatives for texture evaluation
  are not correct.
- Multiple passes do not work entirely correct (they are not accurate
  to begin with, but could be better).
