The first incarnation assumed that proxies were local objects per
definition. Unfortunately that makes it impossible to - for example -
reference-link an entire Scene with proxies, to be used as a special
character set.
This commit makes the proxy implementation also a bit more clear.
Related work: the scene-sets were not executed fully or correctly for
the dependency graph. That happens now (in 3d view) as well.
Vertex/Face/Frame duplication now draws using OpenGL display lists. Makes
drawing go much faster (2-5 times, depending on size of duplicated object).
This system uses boundbox checks too, so outside of view it draws faster.
Note for face duplication: I've fixe a bug for incorrect alignment when
the parent was rotated when a parenting happened, the 'inverse parent
correction matrix' then messed up alignment. For face duplication it now
works OK, but for vertex-dupli not... need a way to fix this backwards
compatible.
Notes:
- Only referenced groups (from other files)
- Only 1 group (no more duplicates using same group yet)
- Only Proxy working well for Armature or Empty
Is going to be reviewed in Plumiferos team; but target is that this will
solve a major animation pipeline bottleneck :)
Usage; select group, alt+ctrl+p, pick an object you want to proxify.
THE OBJECT PROXY
Or simple said; local control of referenced data from libraries.
Having library files with references is a very common studio setup, and
Blender did do quite well in that area. Were it not that for character
setups it was impossible to use still.
This commit will enable a full rig+character to remain in the library,
and still have - under strict control - local access for animation edits.
Full log:
http://www.blender3d.org/cms/Proxy_Objects.824.0.html
New "Dimension" button: when using TAB to cycle over buttons, the dimension
event was sent multiple times, accumulating scaling. The code was also not
prepared to handle multiple changes at one event.
Also: added object_get_boundbox(Object *ob) in BKE_object.h, so the code
now really supports most primitives in Blender.
This commit brings back:
- Field Render
- MBlur Render (old style)
- Border render with or without cropping
Note: Field Render is not supported in Compositor yet. Blurring or filter
will destroy field information.
Both MotionBlur as Field render are done before Compositing happens.
Fixes:
- The "Save Buffers" option only worked on single frame renders, not for
Anim render.
- Found an un-initalized variable in Render initialize... this might have
caused the unknown random crashes with render.
Code restructure:
Cleaned up names and calls throughout the pipeline, more clearly telling
what goes on in functions.
This is visible in the updated first image of the Wiki doc:
http://mediawiki.blender.org/index.php/BlenderDev/RenderPipeline
- particle duplicators should not include parent animation (error in
duplicator recode of last december)
- added exception for 'died' particles to keep correct orientation
Also in this commit:
- added comment in code to explain why vertexnormals in mesh are equal to
vertex location when no faces exist
- cleanup of BKE_object.h for functions that don't need export.
A full detailed description of this will be done later... is several days
of work. Here's a summary:
Render:
- Full cleanup of render code, removing *all* globals and bad level calls
all over blender. Render module is now not called abusive anymore
- API-fied calls to rendering
- Full recode of internal render pipeline. Is now rendering tiles by
default, prepared for much smarter 'bucket' render later.
- Each thread now can render a full part
- Renders were tested with 4 threads, goes fine, apart from some lookup
tables in softshadow and AO still
- Rendering is prepared to do multiple layers and passes
- No single 32 bits trick in render code anymore, all 100% floats now.
Writing images/movies
- moved writing images to blender kernel (bye bye 'schrijfplaatje'!)
- made a new Movie handle system, also in kernel. This will enable much
easier use of movies in Blender
PreviewRender:
- Using new render API, previewrender (in buttons) now uses regular render
code to generate images.
- new datafile 'preview.blend.c' has the preview scenes in it
- previews get rendered in exact displayed size (1 pixel = 1 pixel)
3D Preview render
- new; press Pkey in 3d window, for a panel that continuously renders
(pkey is for games, i know... but we dont do that in orange now!)
- this render works nearly identical to buttons-preview render, so it stops
rendering on any event (mouse, keyboard, etc)
- on moving/scaling the panel, the render code doesn't recreate all geometry
- same for shifting/panning view
- all other operations (now) regenerate the full render database still.
- this is WIP... but big fun, especially for simple scenes!
Compositor
- Using same node system as now in use for shaders, you can composit images
- works pretty straightforward... needs much more options/tools and integration
with rendering still
- is not threaded yet, nor is so smart to only recalculate changes... will be
done soon!
- the "Render Result" node will get all layers/passes as output sockets
- The "Output" node renders to a builtin image, which you can view in the Image
window. (yes, output nodes to render-result, and to files, is on the list!)
The Bad News
- "Unified Render" is removed. It might come back in some stage, but this
system should be built from scratch. I can't really understand this code...
I expect it is not much needed, especially with advanced layer/passes
control
- Panorama render, Field render, Motion blur, is not coded yet... (I had to
recode every single feature in render, so...!)
- Lens Flare is also not back... needs total revision, might become composit
effect though (using zbuffer for visibility)
- Part render is gone! (well, thats obvious, its default now).
- The render window is only restored with limited functionality... I am going
to check first the option to render to a Image window, so Blender can become
a true single-window application. :)
For example, the 'Spare render buffer' (jkey) doesnt work.
- Render with border, now default creates a smaller image
- No zbuffers are written yet... on the todo!
- Scons files and MSVC will need work to get compiling again
OK... thats what I can quickly recall. Now go compiling!
in other layers (or hidden with local view).
In my search for the absolute minimum of recalculations, changes are only
flushed when they're visible. On changing layers, the tags then are just
set again (for everything that potentially moves) to ensure proper state.
However, it didn't work proper for linked Mesh objects that changed in
editmode, the Derivedmesh callback then accessed memory out of bounds.
The current dependency code was more designed for animation systems...
updating display data should work too, but might need some more tests!
(Thanks Andrea for clear error sample!)
- fix DerivedMesh.getMinMax implementations to set min & max when
there are no vertices
- mesh boundbox calc was wrong in some cases, messed up HOMEKEY
and localview zooming
Aim was to get a total refresh of the animation system. This
is needed because;
- we need to upgrade it with 21st century features
- current code is spaghetti/hack combo, and hides good design
- it should become lag-free with using dependency graphs
A full log, with complete code API/structure/design explanation
will follow, that's a load of work... so here below the list with
hot changes;
- The entire object update system (matrices, geometry) is now
centralized. Calls to where_is_object and makeDispList are
forbidden, instead we tag objects 'changed' and let the
depgraph code sort it out
- Removed all old "Ika" code
- Depgraph is aware of all relationships, including meta balls,
constraints, bevelcurve, and so on.
- Made depgraph aware of relation types and layers, to do smart
flushing of 'changed' events. Nothing gets calculated too often!
- Transform uses depgraph to detect changes
- On frame-advance, depgraph flushes animated changes
Armatures;
Almost all armature related code has been fully built from scratch.
It now reveils the original design much better, with a very clean
implementation, lag free without even calculating each Bone more than
once. Result is quite a speedup yes!
Important to note is;
1) Armature is data containing the 'rest position'
2) Pose is the changes of rest position, and always on object level.
That way more Objects can use same Pose. Also constraints are in Pose
3) Actions only contain the Ipos to change values in Poses.
- Bones draw unrotated now
- Drawing bones speedup enormously (10-20 times)
- Bone selecting in EditMode, selection state is saved for PoseMode,
and vice-versa
- Undo in editmode
- Bone renaming does vertexgroups, constraints, posechannels, actions,
for all users of Armature in entire file
- Added Bone renaming in NKey panel
- Nkey PoseMode shows eulers now
- EditMode and PoseMode now have 'active' bone too (last clicked)
- Parenting in EditMode' CTRL+P, ALT+P, with nice options!
- Pose is added in Outliner now, with showing that constraints are in
the Pose, not Armature
- Disconnected IK solving from constraints. It's a separate phase now,
on top of the full Pose calculations
- Pose itself has a dependency graph too, so evaluation order is lag free.
TODO NOW;
- Rotating in Posemode has incorrect inverse transform (Martin will fix)
- Python Bone/Armature/Pose API disabled... needs full recode too
(wait for my doc!)
- Game engine will need upgrade too
- Depgraph code needs revision, cleanup, can be much faster!
(But, compliments for Jean-Luc, it works like a charm!)
- IK changed, it now doesnt use previous position to advance to next
position anymore. That system looks nice (no flips) but is not well
suited for NLA and background render.
TODO LATER;
We now can do loadsa new nifty features as well; like:
- Kill PoseMode (can be option for armatures itself)
- Make B-Bones (Bezier, Bspline, like for spines)
- Move all silly button level edit to 3d window (like CTRL+I = add
IK)
- Much better & informative drawing
- Fix action/nla editors
- Put all ipos in Actions (object, mesh key, lamp color)
- Add hooks
- Null bones
- Much more advanced constraints...
Bugfixes;
- OGL render (view3d header) had wrong first frame on anim render
- Ipo 'recording' mode had wrong playback speed
- Vertex-key mode now sticks to show 'active key', until frame change
-Ton-
- after grab/duplicate the softbody didn't get a reset signal
- added 'copy properties' for softbody settings
- duplicate object didn't copy softbody yet
1) Curve deform
http://www.blender3d.org/cms/Curve_Deform.392.0.html
Works simple as expected, but keep track of the rotation axis
in F7 buttons (Track X Y Z)
Only Mesh deform supported now.
Code changes:
- centralized deformation calls in curve_modifiers() mesh_modifiers()
etcetera. Here also other effects can be added like wave. Now the
evaluation order is fixed, but should become optional. It also doesnt
use the Displist anymore as deform-input. That latter part is unfinished
yet.
This code also is used for Hooks and will be needed for softbody
- made convention stricter that displists are being checked on in
drawobject(), this to prevent routines to make new displists recursively
(like armature does). Now a freedisplist() is sufficient to signal that
a new displaylist should be made.
2) Object Hooks
http://www.blender3d.org/cms/Object_Hooks.391.0.html
Support for Hooks is added to Mesh, Lattice, Curve and Surface objects.
For Armatures this would require some more work & research.
Main goal for this feature is to provide quick & simple access to the
underlying geometry in Objects on Object level, supporting hierarchies and
Ipos etc.
- small additions and fixes to enable the demo mode;
- Added sleep() to Blender.sys and 17 new functions to Blender.Window module:
things to help demo script writing and as a bonus read / write access to Blender's input event queue;
- updates in docs, those interested please check Window.py in python/api2_2x/doc/ to read about the new Blender.Window functions.
----
Demo mode should be working well now for (I) playing rt animation -- aka ALT+A -- and (II) rendering pics and anims and playing anims. I'll still add access to radiosity data and functions.
PS: Joseph Gilbert made (II) possible with the Scene.Render module he added for 2.32. He's been coding great things for bpython, so I'd like to take the chance to point that and thank him here.
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
