add arguments to calculate normals when converting to bmesh:
BM_mesh_bm_from_me, DM_to_bmesh
This gives some speedup to undo (which didnt need to re-calculate vertex normals), and array modifier which doesnt need to calculate face normals at all
* Rename some math functions:
len -> length
len_squared -> length_squared
normalize_len -> normalize_length
* This way OpenCL uses its inbuilt length() function, rather than our own. The other two functions have been renamed for consistency.
* Tested CPU, CUDA and OpenCL compile, should be no functional changes.
An optional 'internal' argument was added to the bpy.data.texts.load() operator.
The changes in revision 57153 were reverted, so that the is_in_memory and is_dirty
properties of text datablocks are not editable again.
In the C API layer, BKE_text_load_ex() was introduced to allow for optionally
making text datablocks internal after loading.
Crash was happening on windows platforms only and was caused
by some specifics about how CRT works.
Basically, blender and all of the .dll are compiled with /MT
flag, which means blender.exe and all .dll are using separate
environments. This makes it impossible to pass file descriptors
from blender to other dll, because it becomes invalid in the dll.
And this is exactly what was happening: OIIO was trying to open
movie file with all known plugins and one of them was zlib. And
the way OIIO was using zlib API is opening the file using Boost
and passing a file descriptor to zlib. And since zlib was a
dynamic library this lead to general issues using this descriptor
in zlib code.
Solved by linking to zlib statically. This allows to safely pass
file descriptor to zlib API. Alternative would be to compile all
the stuff with /MD flag, but that's much bigger and less robust
way to fix the issue.
Tested on windows using msvc2008, scons plus cmake both 32 and 64
bit versions. Seems to be working fine.
Further tweaks for mingw and msvc2012 could be needed tho.
New OSX "Life resize" was also being called during opening of windows - when things are
not initialized yet. Crashed on opening full-screen window (which is animated in OSX).
* Cycles Mix closure could render strange effects, when the user entered a value out of the 0...1 range. This was already clamped for OSL, clamp for SVM as well.
- expose unwrap as a menu (rather then a regular button that pops up a menu)
- move 2 extrude buttons into one menu button, also do the same for the mesh menu.
* Panorama Camera was not working for Blender Internal and Cycles anymore.
Code checked for Freestyle render layer flag, but as the flag is enabled per default, it broke Panorama camera in all cases. It made no sense to check this on a render layer basis anyway... check if Freestyle is enabled in general now instead.
the second time, as for example Intel CPU startup time is 9 seconds.
* Adds an cache for contexts and programs for each platform and device pair,
which also ensure now no two threads try to compile and write the binary cache
file at the same time.
* Change clFinish to clFlush so we don't block until the result is done, instead
it will block at the moment we copy back memory.
* Fix error in Cycles time_sleep implementation, does not affect any active code
though.
* Adds some (disabled) debugging code in the task scheduler.
