compilation. Currently, it is not yet active by default, but
Genscher wanted to do some tests.
It can be used to distribute the computation load onto multiple shared-
memory CPUs by splitting the domain along the y-axis (assuming a
gravity force along z). However, there is no load balancing: so
if there's fluid only in one of the y-axis halves you will not get
a speedup for 2 CPUs.
- Added a fix for the memory allocation bugs #7120 and #6775. In
solver_init.cpp there are now several variables max___MemChunk
(line 692+), that set upper limits for various systems. The same
problem existed for mac & linux, but the limit is higher, so
it probably went by undetected. The windows limit is currently 1GB,
if the strange 700MB limit problems mentioned in the bug regports the
bugs persist, this could be further reduced. For 64bit compilations
this problem shouldn't exist anyway.
What's still missing is a display of how much the resolution was
reduced to fit into memory...
- And some minor solver code cleanup.
====================
The MeshDeform modifier can deform a mesh with another 'cage' mesh.
It is similar to a lattice modifier, but instead of being restricted
to the regular grid layout of a lattice, the cage mesh can be modeled
to fit the mesh better.

Implementation Notes:
- OpenNL has been refactored a bit to allow least squares matrices to
be built without passing the matrix row by row, but instead with
random access. MDef doesn't need this actually, but it's using this
version of OpenNL so I'm just committing it now.
- Mean value weights for polygons have been added to arithb.c, a type
of barycentric coordinates for polygons with >= 3 vertices. This
might be useful for other parts of blender too.

Solving is now done independent of scale, by scaling the chain to have a
size of about 1.0. This solves some issues with small or big chains, and
also makes the IK stretch setting independent of scale. The latter breaks
backwards compatibility somewhat, but is an improvement over what it did
before.
draws into the
frame.
This patch includes some changes I made...
* use blenders bitmap fonts (rather then own fonts)
* select font size
* user interface layout changes
* Marker as another image stamp option
Also added some new API calls
BMF_GetFontHeight(font);
BMF_DrawStringBuf(...); - so we can draw text into an imbuf's image buffer.
get_frame_marker(frame) - get the last marker from the frame.
IMB_rectfill_area(...) - fill in an image buffer with a rectangle area of color.
TODO - draw stamp info in 3d view, at the moment it just displays in the animation.
applied MT_QueryAssert_patch.diff part of
patch [#6994] Fixing warnings: conversion from string constant to char *
Submitted by Renato Perini (mjordan).
Thanks, Renato!
Bugfix:
The mem cache limitor didn't take mmap-allocated memory into account,
resulting in effectively disabling it, since all imbuf-data is
currently allocated using mmap.
Tooltip getStringSize and getBoundingBox correction
Not really any user-visible changes here, but a nice clean-up of
internal font drawing functions, in this case used in tooltips.
Thanks!
settting WITHOUT_BF_INSTALL='true' will disable
the copying to INSTALL_DIR
you can use that in your user-config.py or commandline
slipping in minor cleaning for Os X builds
-----
Bugfixes for #6816 and #6988: Under Windows, Blender would crash if boolean
operations were done on objects which resulted in an empty mesh. Problem was
"iterators" created for ConvertCSGDescriptorsToDerivedMesh() tried to access
invalid memory.
turntable code should work reasonabilly well now.
fly code need works but is no more insane on Os X.
transform object is not present here.
if you find the movements a bit slow, you can speed
it in the preferences up to 2x in the view & controls
panel.
button1 (left) of the device let you switch between
the 3 modes. button2 let you switch between
unconstrained and dominant mode.
the plugin must be named 3DxNdofBlender.plug
and be placed in a folder named plugins in same
folder as executable
check no scaling is done in the plugin
please check it works ok on 3 platforms
-----
More improvements to boolean tools. The main change (although very little in
code) is changing fuzzy comparisons of floating point values. For testing, a
new define is added in intern/boolop/intern/BOP_MathUtils.h called
VAR_EPSILON, which enables better comparisons. This is turned on by default;
undefining it will revert to using the previous comparisons. The downside of
these new comparisons is a loss in speed, but the resulting meshes are more
likely to be manifold (although still not always).
The other changes include speed improvements based on profiling results and
fixes for the improper creation of triangular faces with only two vertices.
As previously the plugin itself is available
on his site :
http://cubelogic.org/blender/3dcnxplug-lin.c
or on mine (soon) :
http://jlp.nerim.net/dev/6dof/
Please let me know if any problem, i cannot
test.
We have now patches for our 3 main platforms
features are still minimal, but will follow
soon.

Bugfix #6847: Previous fix for "spikes" when using booleans caused creation
of faces with only two unique vertices ("eekadoodles"). This patch cleans up
the test for triangles with near-colinear vertices so PHANTOM faces can be
used again, and also adds a hack for now which removes any eekadoodle faces.
I haven't figured out yet exactly how the faces are being created; if I can
do so and fix it the hack will be removed.
for NDOF devices
I applied the patch but cant test so please
let me know if any problem.
the plugin itself can be found either
on Ettore site http://cubelogic/blender/
or on my site http://jlp.nerim.net/dev/6dof/
on my site there is also the source of
mac plugin
-----
Bugfix #6847: Boolean code was marking some valid faces as "PHANTOM" when the
three vertices were nearly co-linear (according to its tests). This
introduced holes into one or both meshes which could then result in either
holes in the final results and/or spurrious faces which should have been
split.
This commit removes the code in question until either an alternative test is
coded.
which caused faces of convex objects to be classified wrongly. Also removed
some dead code. For convex objects, the BSP trees would also be literally
orders of magnitude larger than they were supposed to be (one test with a
5000 face torus reduced the BSP tree size from 5.96 million nodes to just 72.1
thousand).
work only in non camera mode in 3D view
need the external plug-in to be compiled separately
line 894 of ghostwinlay.c must be replaced with
values adapted at your system
see mailing list for features planned and how
to use
notes :
it compiles but is non functional
lacks the platform specific changes in ghost ( i cant test windows)
lacks the code for plug-in.
the platform specific code will be added when we sync with Ettore work
the plug-in itself cannot be added here
- fix for 3DPlugin compile
- cleanup of bullet path
- removed PHY_ODE project from 3D plugin too, not used anymore
Now all configurations should build again, let me know of any problems!
Not been able to test if the 3DPlugin is actually working,is job for another day ;)
Also the 3DPlugin is compiled without OpenExr, this needs to be looked into once too.
- fixed WinTab locking positioning into absolute mode
- hopefully fixes [ #5586 ] Cursor control
Note: Setting the extent of the digitizing context causes Application to override
system settings for pen/mouse control. Removing this fixed the issue.
