Volumes can now receive shadows from external objects, either raytraced shadows or shadow maps.
To use external shadows, enable 'external shadows' in volume material 'lighting' panel. This an extra toggle since it causes a performance hit, but this can probably be revisited/optimised when the new raytrace accelerator is integrated. For shadow maps at least, it's still very quick.
Renamed 'scattering mode' to 'lighting mode' (a bit simpler to understand), and the options inside. Now there's:
- Shadeless
takes light contribution, but without shadowing or self-shading (fast)
good for fog-like volumes, such as mist, or underwater effects
- Shadowed (new)
takes light contribution with shadows, but no self-shading. (medium)
good for mist etc. with directional light sources
eg. http://vimeo.com/6901636
- Shaded
takes light contribution with internal/external shadows, and self shading (slower)
good for thicker/textured volumes like smoke
- Multiple scattering etc (still doesn't work properly, on the todo).
Added a way to view and edit Keying Sets via the Scene Buttons. These are still some tweaks needed to make this really workable, but should still work well enough for simply viewing and tweaking existing Keying Sets created using other means.
Additional bugfixes:
* Adjusted the size of labels on properties that had a 'label' for their name. Now it uses 1/3 of the total width instead, which looks much better for most cases.
* Added missing entries for adding Force Fields from the Info-header 'Add' menu. At some point we should unify this menu with the popup operator's one, since this is exactly the kind of situation we had hoped in avoid with new UI architectures.
* Moved all the operator defines for keyframing stuff to the 'intern' anim header instead
* Fix loading issue of blend files with smoke collision objects (was disabled on purpose since it will be subject of change, but can be solved using do_versions() later)
one active. Now there's a function to get the pointer + property from
the UI, just like for the animation operators.
Also two fixes for fileselect events, regions are now preserved so that
context is restored to the old region, and the cancel callback is called
when the operator is cancelled.
So means minimum twist and twist smoothing are now used.
the Z up quaternion from the path is rotated to match the up axis given.
There was no logical rule for the up vector, some cases flipped the normals when used with the CurveDeform modifier.
Use the default X-Up behavior and match other settings with this. (comments explain this in detail).
- Interpolating quaternions didn't work in some cases, disabled for now.
- 'no_rot_axis' is different from in 2.4x since it now removes rotation from the tilt whereas before it edited the axis before calculating the tilt.
* Unified scene wide gravity (currently in scene buttons)
instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group
setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
- "Point" is most like the old effectors and uses the
effector location as the effector point.
- "Plane" uses the closest point on effectors local xy-plane
as the effector point.
- "Surface" uses the closest point on an effector object's
surface as the effector point.
- "Every Point" uses every point in a mesh effector object
as an effector point.
- The falloff is calculated from this point, so for example
with "surface" shape and "use only negative z axis" it's
possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer
just spherical.
* New effector parameter "flow", which makes the effector act as
surrounding air velocity, so the resulting force is
proportional to the velocity difference of the point and "air
velocity". For example a wind field with flow=1.0 results in
proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random
flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force
(note. the z-axis is the surface normal in the case of
effector shape "surface")
* New "force field" submenu in add menu, which adds an empty
with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector
system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for
particles, softbody & cloth, since their final effect depends on many external
factors, like for example the surface area of the effected faces.
Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through
DAG_id_flush_update(..).
Known issues
* Curve guides don't yet have all ui buttons in place, but they
should work none the less.
* Hair dynamics don't yet respect force fields.
Other changes
* Particle emission defaults now to frames 1-200 with life of 50
frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to
free pidlists after use :).
* Rendering twice or more could crash layer/pass buttons.
* Compositing would crash while drawing the image.
* Rendering animations could also crash drawing the image.
* Compositing could crash
* Starting to rendering while preview render / compo was
still running could crash.
* Exiting while rendering an animation would not abort the
renderer properly, making Blender seemingly freeze.
* Fixes theoretically possible issue with setting malloc
lock with nested threads.
* Drawing previews inside nodes could crash when those nodes
were being rendered at the same time.
There's more crashes, manipulating the scene data or undo can
still crash, this commit only focuses on making sure the image
buffer and render result access is thread safe.
Implementation:
* Rather than assuming the render result does not get freed
during render, which seems to be quite difficult to do given
that e.g. the compositor is allowed to change the size of
the buffer or output different passes, the render result is
now protected with a read/write mutex.
* The read/write mutex allows multiple readers (and pixel
writers) at the same time, but only allows one writer to
manipulate the data structure.
* Added BKE_image_acquire_ibuf/BKE_image_release_ibuf to access
images being rendered, cases where this is not needed (most
code) can still use BKE_image_get_ibuf.
* The job manager now allows only one rendering job at the same
time, rather than the G.rendering check which was not reliable.
* #19501: Only the first user of multi-user IPO's were getting converted to AnimData.
Now, this AnimData gets converted multiple times - once for each user. This will mean that multi-user actions will no longer be multi-user after conversion though, although this could be fixed manually if there really is such a need.
* #19503: Nasty memory leaks when duplicating objects with AnimData
Fixed a few little oversights made when coding the copying code for NLA-data (which resulted in exponential copying-loops of doom), and sanitised the AnimData copying code for ID-blocks to be simpler to manage.
After code review and experimentation, this commit makes some changes to the way that volumes are shaded. Previously, there were problems with the 'scattering' component, in that it wasn't physically correct - it didn't conserve energy and was just acting as a brightness multiplier. This has been changed to be more correct, so that as the light is scattered out of the volume, there is less remaining to penetrate through.
Since this behaviour is very similar to absorption but more useful, absorption has been removed and has been replaced by a 'transmission colour' - controlling the colour of light penetrating through the volume after it has been scattered/absorbed. As well as this, there's now 'reflection', a non-physically correct RGB multiplier for out-scattered light. This is handy for tweaking the overall colour of the volume, without having to worry about wavelength dependent absorption, and its effects on transmitted light. Now at least, even though there is the ability to tweak things non-physically, volume shading is physically based by default, and has a better combination of correctness and ease of use.
There's more detailed information and example images here:
http://wiki.blender.org/index.php/User:Broken/VolumeRendering
Also did some tweaks/optimisation:
* Removed shading step size (was a bit annoying, if it comes back, it will be in a different form)
* Removed phase function options, now just one asymmetry slider controls the range between back-scattering, isotropic scattering, and forward scattering. (note, more extreme values gives artifacts with light cache, will fix...)
* Disabled the extra 'bounce lights' from the preview render for volumes, speeds updates significantly
* Enabled voxeldata texture in preview render
* Fixed volume shadows (they were too dark, fixed by avoiding using the shadfac/AddAlphaLight stuff)
More revisions to come later...
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
This (biggish) commit generalises the rotation modes functionality added for Bones, allowing Objects to use the various Euler Rotation orders, Axis-Angle, and Quaternion rotation representations.
I've also cleaned up the nomenclature of the rotation-related settings so that the naming styles are more consistent with each other. Unfortunately, this will break all files involving object or bone rotation animation made in 2.5 versions (2.4x will still get correctly converted).
General Notes:
* By default, Objects still default to using Eulers, while Bones will use Quaternions by default still.
* I've fixed all areas that I'm currently aware of to work with these changes. However, there are probably a few places where I've missed a few changes (i.e. auto-keyframing will need attention later).
* Removed the old "IPO-Keys" stuff from Transform code. I'm unlikely to restore this in the near future, and trying to fix that to include support for this commit would have been too much work.
* Added missing RNA wrapping for Scene -> AnimData
* Fixed bug (with temp-fix) where sequence strips with no names couldn't be animated properly. Currently, this will just use the index of the strip, although that is likely to be mutable (adding/removing strips will change it).
* Removed some old unused code from action.c
Main Feature:
* It is now possible to choose which AnimData block is the 'active' one for editing, and/or select them too. AnimData blocks are generally the dark blue and lighter-blue expanders (i.e. Scene, Object, Camera, Lamp, Curve, Armature, etc.)
* Objects are no longer selected/deselected when AKEY is used to toggle selection of channels. This was getting a bit annoying.
* Following on from selection of AnimData blocks, it is now possible to select/make active an AnimData block in the animation editors, and change the active action for that block via the 'Animation Data' panel in NLA Editor's properties region.
--> Be aware that user-counts are not totally handled correctly there yet, so some funky behaviour might be seen...
--> It is possible to assign a new action, or to assign an existing one, allowing to switch between actions as in the past with Actions/IPO Editors...
Other tweaks:
* Some code tweaks towards making the 'Euler Filter' feature for Graph Editor working sometime soon
* Added some backend code for snapping the values of keyframes to a single value. Still need to work out some UI for it though.
* Shuffled the code for ACT_OT_new() around, and removed the poll() callback so that it worked in NLA too.
* Fixed some more notifier bugs with deleting bones and a few other editmode operations for Armatures.
* Threading buxfix letting MSVC Debug builds crash because of corrupted std::lists
* Adopted two property ranges
* Changed the mixdown volume to set the device volume instead of the volume of every sound.
I also removed the private redefinition of m_logicmgr in SCA_BasicEventManager, which was already defined protected in the parent class SCA_EventManager and thus caused a bug letting GE crash here because of an uninitialized pointer.
Drivers can now be copied/pasted for single properties, allowing drivers set up on one property to be added to a few other properties relatively easily.
Also, added description strings for the other driver-button operators.
- BLF_lang_init used confusing IFDEF's, unlikely this was well tested. Split this into 3 functions for Apple/Win32/Unix, Unix uses BLI_gethome_folder(), cant test others, ideally they should use BLI_gethome_folder too but needs testing.
Possibly each os cant be made to use BLI_gethome_folder and the separate func's can be removed (please test).
- units, hectometers were displayed wrong.
* Loading old (2.4x) files with keyframes now inits them properly so that keyframes are tagged as normal keyframes not breakdowns
* TrackTo consraint was flagged wrongly for adding it with a target. This meant that the target didn't get set when using the Ctrl-Shift-C hotkey.
* copied I/O scripts
* copied, modified rna_*_api.c and rna_*.c
I/O scripts not working yet due to slight BPY differences and RNA changes. Will fix them later.
Not merged changes:
* C unit testing integration, because it is clumsy
* scons cross-compiling, can be merged easily later
- Commands from the history wont get modified in-place when you cycle back and re-use them.
- Ctrl Left/Right skip words.
- Autocompletion on a variable that has no alternatives adds a '.'
'bpy' -> 'bpy.', generally more useful since autocomp again will give the members of bpy
also moved text_check_* functions into BKE_text.h for the console to access.
* delta-transforms for objects should work again. These were basically extra transforms that could get added on top of the values calculated from animation values.
* Added some skeleton code for fixing paths when some data needs to be renamed.
- rename WM_OT_ten_timer to WM_OT_redraw_timer
- added iterations argument to run more then 10 times (10 is default still)
- use report api rather then always calling a popup directly.
- added a new test that draws every region without swapping.
- dont show the info popup when operators are called from python.
- operators called from python now print reports, useful with the interactive console.
eg.
>>> bpy.ops.wm.redraw_timer(type='DRAW_WIN', iterations=300)
Info: 300 x Draw Window: 4168.56 ms, average: 13.8952
% sign for percentage assuming it is between 0-100, while factor is
for values 0-1.
Move collision setting absorption from modifier to collision settings,
was inconsistent to have it there as the only one, and made it have
range 0.0-1.0 instead of 0-100.
* Path Constraint option (i.e. this creates a follow-path constraint but doesn't actually parent the object to the curve) works now. Fixed a crash here too.
* Follow Path option (i.e. parent the object to the curve, and follow it), is not working correctly yet. Some matrix seems to get set wrongly.
* Fixed mixdown volume being int instead of float
* Fixed audio muting for sequencer not working
* Added 3D listener settings with RNA (not working in GE yet)
* Copy Rotation constraint "should" work ok for custom rotation orders now. It now converts both rotations to the form used by the owner. So far, this doesn't seem to have broken any of the test rigs in my test-suite, though new specimens for the hall of flakiness are always welcome.
* Fixed many RNA wrapping bugs for Armature data.
- Fixed a few wrong tooltips
- Made proper refreshes for restpose/posed, etc.
* Started converting special quaternion interpolation for Pose Sliding tools (push/relax/breakdown), though this doesn't seem to be working correctly yet.
-->> Help to get these working right is welcome :)
* #19419: PoseLib rename/remove tools could crash when an invalid
(However, now care is needed when touching that index field, since the warnings can keep piling up)
* Added Browse Poses for PoseLib to the toolbar
* Removing constraints from bones now properly updates. A DAG rebuild is now forced, and the constraint flags are cleared.
* Attempting to improve the situation with Copy Rotation constraint and rotation orders other than xyz. Unforunately, it looks like a different method is required...
* Updating Preview Range settings results in correct updates for Animation Editors
* Compositing nodes now correctly animate when the values were set by IKEY/RMB on suitable node parameters. Beware that these nodes are not relinkable node-trees, hence the standard code not working.
* Ctrl-P to parent objects to bones now works in Pose Mode too. I needed to add a special keymap entry for this, though I thought this would have been better to be automatically inherited/present from Object keymap already?
* Ctrl-P -> Parent to Bone option now works correctly again. 1.5 lines of code missing here...
* Breakdowns tool now shows custom cursor during 'modal' phase so that it's not that confusing what's going on.
This commit restores the 'Relax Pose' tool, and also introduces two others: 'Push Pose' and 'Pose Breakdowner'.
Be aware that this commit is just the initial starting point, with some parts yet to be done.
A short description of these tools follows:
* Relax Pose (Alt-E) - makes the current pose more like the poses on either side of it
* Push Pose (Ctrl-E) - exaggerates the current pose
* Breakdowner (Shift-E)[not working yet] - when this works, it will allow for interactive selection of a good in-between pose to act as a breakdown.
Todo's:
* Connect up the 'percentage' slider in the operator settings to allow these effects to be dialed in/out, exaggerating/relaxing/moveing-between-keyframes by varying degrees until the desired effect is reached.
* Allow these effects to be interactively dialed in/out. The idea is to use the mouse to interactively set the percentage slider value initially, then use the percentage slider to tweak later.
* Figure out why breakdown breaks down
* VecLerp3f and Vec2Lerp3f - interpolate 3 2d/3d vectors from 3 weights
* AngleToLength(angle) - useful for making even width shell/walls based on the angles of the surrounding geometry from each point. (same method used in 2.4x python solidify script).
also quiet some warnings.
- remove falloff setting now the curve is used.
- bugfix for airbrush & tablet, with no movement it would assume 1.0 pressure.
- rna, use the use_* prefix for brush options.
* Changed the non-projection paint code to use the brush falloff curve, rather than a predefined falloff. This makes non-projection painting in the 3d view, and image editor painting much more consistent with other brush usage.
New stuff
- Bending springs for hair dynamics.
Code cleanup & optimization
- Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better.
- Removed child seams, something better will come here too :)
- Normal particle drawing data is now saved between redraws if the particles don't move between redraws.
* For example rotating the 3d view is now realtime even with 1M particles.
- Many random values for particles now come from a lookup table making things much faster.
- Most accessed small point cache functions are now much faster as macros.
- Lot's of general code cleanup.
- Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)
Note sure what to do with this one, and personally think
we should avoid using macros for this kind of thing:
V_GROW(edges);
source/blender/editors/mesh/loopcut.c:232: warning: value computed is not used
Added a utility function to check which transforms for an object or bone are animated, returning these as bitflags and/or optionally retrieving the relevant F-Curves too. Beware that this method may not be working correctly yet, but it shouldn't hurt anyone in the meantime :)
Also, split RNA-path building function up into a version which only creates the path up to the given struct, with the other parts being added later.
* The image panels in the image editor and texture buttons
should be more complete now, with working new/open,
refreshes, and using the layout engine.
* Paint panels in image editor are now consistent with the
ones in the 3d view toolbar.
* Curves panel also uses layout engine, and doesn't look
squashed anymore.
