PointerProperty
blender wasnt freeing ID-Properties when freeing the material copy.
Checked that this isnt a problem for other preview types - texture/world/lamp.

embedding python.
CMake build option WITH_PYTHON_MODULE, will build ./bin/bpy.so
This allows 'bpy' to be imported from python or other applications/IDE's which embed python, eg:
python -c "import bpy ; bpy.ops.render.render(write_still=True)"
This runs in background mode and has similar restrictions to running a script:
blender --background --python test.py
TODO:
- install to site-packages with blender scripts
- add support for imp.reload()

New render output option "No Output", which renders without
forcing an editor to show an image. Nice for people who
prefer to setup composites with background image view.
|
|
render out short segments of shots to be previewed with accurate
timing.
|
|
header static for blenlib, blenkernel and editors.
|
|
* Moving a texture slot didn't keep the moved slot active.
* Copy & paste for particle textures didn't work.
* New textures weren't freed properly.
|
|
what did I learn from this?
"if at first you don't succeed..
you're not kaito." ;)

New "auto render" now prevents calling anim-updates, that's
not needed (and popped back transformed keyed objects).
|

When using masks or other simple 3D elements in composites, doing
a layer re-rendering on a node is a bit clumsy all the time.
This commit does two things to help:
- new hotkey "Z" in node editor automatically finds render layer
that changed and re-renders it + composites
- option "Auto Render" does same, but then after every transform
edit in 3D window
The latter is experimental; real & proper system for this requires
full threaded render support (like previews). But it works!
Demo file:
http://download.blender.org/demo/test/auto_composite.blend
Important fix:
After any render, all the render layers were tagged "changed", which
caused any edit to first totally recomposte everthing. Now it only
composites changes.
Implementation notes
- DAG scene flush now sets 'changed' flags in render layer nodes
- Added notifier for 'transform finished' to trigger the update,
this is temporarily.
|
|
|
|
also removed unnecessary NULL checks (where the pointer was used later without checking).
|
|
MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.
|
|
Object color option now is incorporated in preview render, and
in display in 3D window.
Note that Object-color is "modulating" the render result, it just
multiplies... which is very limited for practical use. This was
added for Apricot game project. The original meaning however was
to replace diffuse only... so specular and light work still correct.
ALso made header for properties editor start on top, to reflect
default (report in tracker).
|
|
New option to start threaded wmJobs, with flag WM_JOB_SUSPEND.
This makes the job wait 1 timer step before running.
Used now for Material Icon render renders, which makes the
big preview to be always rendered first while using UI.
|
|
- On each re-render, the node image was cleared. Skipping this gives
nicer pictures
- Node render was using AA, but unfortunately only 1 sample for Nodes
is being stored. Disable AA render for now, nice speedup too.
|
|
compression.
gives minor overall speedup.
|
|
The icons for materials were always lagging or not updating
at all. I also found it suspicious slow...
It appeared that the icons now store a "mip level", where for
every change in Materials 2 render jobs for icons were started,
one for 32x32 pix, one for 96x96. The latter was cancelling out
the first job almost always.
Also made preview renders detect size, to set amount of tiles
to be rendered. Small icons use 1 part, larger previews 16 now.
All in all, behaves much smoother now! But, will also update
the thread Jobs manager to allow "delayed jobs" like for icons,
these are aggressively put as first in the jobs list.

The bug was 'write_still' was incorrectly being initialized to 'view_context'.
'write_still' should always write an image, so failing silently here is bad behavior.
Also, opengl render and internal render engine operator should use this option the same way.
|
|
- OpenGL still render failed when output format was set to Movie.
Now it just doesn't save a file and renders anyway.
- Bone heat weight was missing 'wait cursor'.
- Waitcursor for Mac Cocoa is back! Made all OS's use the same
nice hourglass cursor.
(Note: this violates Mac UI guidelines, we should rely on the
spinning wheel of death instead. Highly disputable that.)
|
|
OpenGL render now first opens render window.
It used to render first, save file, and then open window to show result.
|
|
Having 2 windows open, rendering to image editor, activate other
window and press F11 -> UI went haywire. Simple fix prevents
render output to be closed in this case.
|
|
|
|
Missing ID tag update.

Material Node trees:
SSS wasn't displaying in Nodes.
Implementation notes:
- Currently copying local data for preview render, only copies
the base material. Node materials are re-used.
- This causes data to be in 2 "main" databases... complex.
- To make it work for preview, I had to add another loop in the
SSS code that checks the original Main dbase. That's marked
as warning in code to be fixed up.
Another bug:
- Material properties "SSS presets" copied settings to the
active material, not to the displayed one. Added RNA call
to retrieve this from Objects.
(Next commit will fix preset scripts)
|
|
Node shaders + textures, showing in Texture properties, with option
"show both previews" had bad ID checking.
|
|
Preview render for node shaders broke, caused by localizing
materials last week, to prevent thread crashes. Fixed now.
Also added a temp fix to draw color-management corrected
node previews default. Will follow scene setting tomorrow.
Also: SSS in nodes doesn't render yet. Was issue in 2.4 too...
|
|
SSS preview render didn't happy.
Was caused by using a Material copy for preview renders (to prevent
crashing in other cases). There were actually 2 errors:
- material copy should be added to preview-main database
- the render was invoked using wrong main database even!
|
|
Compositor: using the icon "render only this layer" now shows
progress in header, allows it to stop, and signals composite in
end.
|
|
Plus some typo fixes in comments.
|
|
F11 pushed a render window to back, but not popped it.
This also works for user prefs btw, not bad ;)
|
|
and endif() which is no longer needed.
|
|
only tags the ID and does the actual flush/update delayed, before the next
redraw. For objects the update was already delayed, just flushing wasn't
yet.
This should help performance in python and animation editors, by making
calls to RNA property update quicker. Still need to add calls in a few
places where this was previously avoided due to bad performance.
|
|
'const char's,.
Only one functional change where Transform orientations passed "" to BIF_createTransformOrientation() which could then have the value written into.
|
|
Material Node shaders: displaying GLSL + rendering previews crashed.
Reason was non-safe threaded access to material nodes. Now, on a preview
render, a full copy of Material is being made.
|
|
- fixed bug in paste material, exposed by stricter warnings.
- removed/renamed various shadowed vars.
- removed BGE lamp.colour, only allow lamp.color attribute.
|
|
|
|
quicktime & sndfile options.
|
|
reporting missing headers & C files.
this is important so IDE's using CMake integration always get blender headers. - QtCreator & MSVC for eg, probably others too.
|
|
an extern into a define.
|
|
- MSVC CFLAGS were being set by only checking WIN32, (breaking non-msvc win32 builds)
|
|
OpenGL viewport render gave squeezed results in cases.
Reason: some graphics cards only give offscreen buffers in multiples
of 256 or 512 (my case).
Current fix uses the actual size returned by graphics card, which
is also safe for too large renders.
More elaborate cropping or matching is for another time.
(Added printf for feedback on this, might disappear)

When 2nd window open, the code that tried to find an Image editor in the
the active window failed.
|
|
|
|
accessed by the UI at the moment, but could eventually be used for saving test-renders.
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'

Issue: in user preferences window, using file selecting caused the
the userpref window to be saved, and not closing.
Reason: design error (by me) in using screen->full tag for denoting
a temporarily screen (like file window). Fixed by using a new
screen->temp variable for it.
System remained unstable though, noticed another issue with freeing
temp screens in wrong places. Seems nice stable now! Will check on
the wiki for relarted issues now.
|
|
also fixed opengl render ortho test.
|
|
* Same fix was already in ED_area_prevspace().
