to rounding noise when trying to detect if previewsize changed. Made it
use a threshold now.
Fix: SHIFT+P in editmode is still push/pull, outside editmode it'll do
the preview render. (Note; editmode changes are not updated anyway!)
Yesterdays commit slightly extended clipping area for window, to ensure
no empty borders get rendered. Unfortunately it reveiled a case in code
that was never handled; clipping code was throwing away good faces. Old
bug... but apparently never showed up?
for compositing code.
Officially malloc/calloc/free is threadsafe, but our secure malloc system
requires all memory blocks to be stored in a single list, so when two
threads write in this list you get conflicts.
- the sub-pixel masks for applying correct filters (gauss and friends)
accidentally were y-flipped, causing bad looking results.
- zbuffer was clipping extremely narrow, causing border pixels to miss
samples, and reveiling alpha that way (was in old render a prob too)
Two new mouse cursors (paintbrush and text I-bar) made by basse (he even made the patch!), inspired by Bart's page.
I also changed screenmain() ever so slightly, so that the standard cursor is always used when the mouse is over a window header.
A commented if in toets.c for flipping the render buffer prevented the propagation of the keypress to handler in space.c
Ton: I added a temporary check for no qualifier but it's missing a test for an opened render window.
The orange -> HEAD merge reverted some scripts to older versions. This only
affected the ones that already existed before the orange branch.
Minor issue, easy to fix.
All in all, kudos to kaito, Hos and others for all the hard work in
bringing (coding, merging) all these changes to the main branch.
here is a quick summary...
Kent
intern/bsp/intern/BSP_CSGMesh_CFIterator.h
removed tri_index (unused variable)
intern/bsp/intern/CSG_BooleanOps.cpp
removed extra ;
intern/string/intern/STR_String.cpp
added <ctype.h>
source/blender/blenkernel/BKE_writeavi.h
moved things around so not doing forward declarations
source/blender/renderconverter/intern/convertBlenderScene.c
changed render.h to render_types.h
source/blender/src/blenderbuttons.c
source/blender/src/editgroup.c
source/blender/src/meshtools.c
added newline
source/gameengine/Ketsji/KX_KetsjiEngine.cpp
commented out include "PIL_time.h" code that requires it is commented out
reading blender/src/writeavicodec.c
(struct keyword to a couple of lines that needed it)
and added:
extern struct Render R;
blender/renderconverter/intern/convertBlenderScene.c
added extern Render R;
added #include "rendercore.h" to get rid of undeclared shade_material_loop
(Not sure if this is right but it fixes it.
Did not fix this problem, is it alright to just pass NULL here or should we chan
ge it to something else:
init_render_materials' : too few
gameengine/Physics/BlOde/OdePhysicsEnvironment.cpp
removed argument to dHashSpaceCreate
commented out dWorldQuickStep since it does not exist
Optimized so only samples inside the screens bounds are drawn.
Wave display detail is based on zoom - so you can view realy large wave files as well as indervidual samples.
Changed logic so an approximation of the wave is displayed rather then just the symetrical amplitude of the sound.
Triangles at start and end were annoying and obscured the start of the sound. made them alpha 0.7 for sound clips only.
a whole CD of music should display well and zoom smoothly now.
again. One exception I didn't solve yet... for the Stucci texture.
In a next commit I will add the preview.blend, so people can play with it!
The rules for preview.blend are pretty primitive still... might become
a bit more advanced later. Here's what it uses now:
- If Object has name starting with 'p' it will get the to-be-previewed
Material or Lamp assigned
- If Object has name starting with 't' its Material gets the texture
assigned for Texture previews
The layer codes for current preview options are in DNA_material_types.h;
#define MA_SPHERE 0
#define MA_CUBE 1
#define MA_FLAT 2
#define MA_MONKEY 3
#define MA_SPHERE_A 4
#define MA_TEXTURE 5
#define MA_LAMP 6
#define MA_SKY 7
(SPHERE_A is sphere with alpha for icons)
- Compositor now is threaded
Enable it with the Scene buttons "Threads". This will handle over nodes to
individual threads to be calculated. However, if nodes depend on others
they have to wait. The current system only threads per entire node, not for
calculating results in parts.
I've reshuffled the node execution code to evaluate 'changed' events, and
prepare the entire tree to become simply parsed for open jobs with a call
to node = getExecutableNode()
By default, even without 'thread' option active, all node execution is
done within a separate thread.
Also fixed issues in yesterdays commit for 'event based' calculations, it
didn't do animated images, or execute (on rendering) the correct nodes
when you don't have Render-Result nodes included.
- Added generic Thread support in blenlib/ module
The renderer and the node system now both use same code for controlling the
threads. This has been moved to a new C file in blenlib/intern/threads.c.
Check this c file for an extensive doc and example how to use it.
The current implementation for Compositing allows unlimited amount of
threads. For rendering it is still tied to two threads, although it is
pretty easy to extend to 4 already. People with giant amounts of cpus can
poke me once for tests. :)
- Bugfix in creating group nodes
Group node definitions demand a clear separation of 'internal sockets' and
'external sockets'. The first are sockets being linked internally, the latter
are sockets exposed as sockets for the group itself.
When sockets were linked both internal and external, Blender crashed. It is
solved now by removing the external link(s).
Would anyone have a problem with me going through and making functions like triangulate, flip normals tri2quad etc all return how many changes made? - then undo+redraw can be done only when needed.
Here are some notes written by Ton:
There's several areas I still have to work on, so don't immediately
report bugs!
- Preview renders in buttons window only supports materials now (no
lamp, texture or world)
- Yafray code has to be checked, it might not work
- unified render doesn't work, might not come back even
- lens flares dont work yet
- motion blur and field render doesnt work yet
- exr libraries are static linked still, we look at making it dynamic
loadable
- the compositor is fully in development still
I really advise people to check on the orange cvs logs too (in case you
ignored it), this has most of the information in it.
At this moment I still have to code for Orange deadlines, that defines
my priority listing mostly. And since we don't use Windows there, doing
testing and bugfixing for that platform would be of great help!
Best features of this commit to checkout:
- Grouping
- full fixed library linking system
- custom bone drawing
- bone layers
- Material/Shading nodes
- recode of render engine
- preview renders
- Compositing options
When the work pressure is a bit lower, I'll make nice docs for all of
this!

Here are my notes on things to look out for as potential problem
spots:
source/blender/blenkernel/intern/displist.c:
+ is initfastshade(void) supposed to be empty? I had
to make it empty to get the merged tree to compile.
source/blender/python/api2_2x/Armature.c:
+ went with the version that had Armature_getLayers()
source/blender/python/api2_2x/Object.c
+ went with the version of Object_getPose() from bf-blender.
(#ifdef 0-ed the other version)
source/blender/python/api2_2x/Pose.[ch]
+ had problems linking due to no Pose_Init() ... copied these
two files straight from bf-blender.
source/blender/src/drawview.c:
+ view3d_panel_properties() had things shifted a few things shifted
a few pixels, otherwise, things were painless
source/blender/src/splash.jpg.c:
+ went with bf-blender version (orange is dead)
source/gameengine:
+ went with bf-blender version -- does not compile due to IMB_rect* stuff,
Ton should look into this.
system tracking changes in nodes, making sure only these nodes and
the ones that depend, are executed.
Further the 'time cursor' now counts down to indicate which node is being
done.
Also: you now can disable the "use nodes" button in the header, edit all
changes, and when you press that button again it nicely executes the
changes.
Still on the todo:
- make compositing threaded
- find a way to nicely exit compositing on input events... so the UI
keeps being responsive
- idea; a 'percentage' menu in header to enforce calculations on smaller
images temporally
threads didn't seem to free allocated memory... while rendering an long
sequence, the 'virtual memory' size grew with about 20 meg per frame.
This appeared to be not related to using malloc in threads (works
properly), but just because threads were not closed properly.
I assumed that the call to SDL_CreateThread() also closes the thread
when finished... but that seems to be not the case. By using a call to
SDL_WaitThread() after the thread was finished the memory heap is stable
again.
This is something I've seen not documented anywhere... the SDL man
pages are horrible sparse; Take for example the official page:
http://manuals.thexdershome.com/SDL-1.2.5/html/sdlcreatethread.html
