Makes it impossible to run from GUI on certain platforms, see T56628.

MASS unit was already implemented for the C api. Only making sure it is
accessible in the python api. Also added 'CAMERA' to the documentation as a valid option.

The statement that PBVH needs to keep track of CCGDM is wrong, PBVH itself
does not care about CCGDM at all, and it's weird for it to carry on this
beast so others can access.
Even more, nobody will actually caring about CCGDM itself, all the usages
were checking whether there is CCGDM or not. This is as good as simply
checking PBVH type.
Tested with an original report T53551 and everything is still stable.

WITH_ASSERT_ABORT was not disabled for release builds. In most cases asserts
are disabled in release builds, but not always.
This also changes the buildbot to use blender_release.cmake instead of
blender_full.cmake, the only effective difference should be WITH_ASSERT_ABORT.

Was caused by missing NULL pointer check in BVH8.
|
|
Was returning -1 as a bool argument,
in this case the caller needs to ensure non-null args.
|
|
Utility to get an int or pointer from a Python expression.

It is likely to be retired, but for until then lets ensure it works.

The assembler template was backing up and restoring ebx, which is
fair enough. However, this did not prevent compiler for putting
result variables to ebx. This was causing data corruption.
In order to prevent this easiest solution is to list ebx in clobbers
for the assembly.
|
|
BVH8 refitting code had a bug.
|

|
The idea is to make find_package() to succeed without any
extra tips given. For this, we need header files to be
harvasted.
|
|
Also clarified some options and decisions.
|
|
There is chance that on a system with both versions installed this
*might* cause some issues. Such system will be pain to support out
of the box anyway.
This change allows to use precompiled libraries without extra
modifications in the config.

Should not include ABI.

- Foe some reason CMake's platform and processor are not intialized there.
- Need to set variables in cache, otherwise they are not visible in the
actual CMake files.

Works similar to how maxOS deals with this.

The script clearly states:
This makes the presumption that you are include al.h like
#include "al.h"
and not
#include <AL/al.h>
The reason for this is that the latter is not entirely portable.
Windows/Creative Labs does not by default put their headers in AL/ and
OS X uses the convention <OpenAL/al.h>.
This commit makes default precompiled OpenAL to be properly detected
and also removes hack on MacOS which was finding the OpenAL package but
then was overwriting include directory.
Note, that new audaspace in 2.8 is using expected #include <al.h>.

Without this find_package(ZLIB) will find ZLib from OpenCollada folder,
which has older ABI and is not what was used to link PNG against.

This is an initial implementation of BVH8 optimization structure
and packated triangle intersection. The aim is to get faster ray
to scene intersection checks.
Scene BVH4 BVH8
barbershop_interior 10:24.94 10:10.74
bmw27 02:41.25 02:38.83
classroom 08:16.49 07:56.15

pavillon_barcelona 09:21.26 09:02.98
victor 23:39.65 22:53.71
As memory goes, peak usage raises by about 4.7% in a complex
scenes.
Note that BVH8 is disabled when using OSL, this is because OSL
kernel does not get per-microarchitecture optimizations and
hence always considers BVH3 is used.
Original BVH8 patch from Anton Gavrikov.
Batched triangles intersection from Victoria Zhislina.
Extra work and tests and fixes from Maxym Dmytrychenko.

Surely, need to compile ffi first :)
Good news are: Python seems static enough now!
|
|
There is system-wide libz development package installed by default,
needed for some other dependencies. This patch ensures Python will
use our own self-compiled Zlib.

Ideally we should remove this difference between platforms, but for now
just do the simple fix.

This involved getting SSL compiled from sources first, ensuring
it is a static library placement independent code. Configuration
is based on what Debian is using. CFlags required to have own
configuration file, which i didn't find a better place that next
to the corresponding CMake file.
It is OpenSSL btw.
It is set to Python via --with-openssl= configuration argument.
This works fine in a clean chroot, but having libssl-dev installed
might make Python to prefer system wide library, This was worked
around by using libssl_pic.a name for the library and modifying
setup.py. Would be cool to ensure system wide libraries are not
a problem, but official release builder is safe against this,
since it will catch possible non-static dependencies.
There is also a new map file which shadows bunch of Python
symbols. Without this Python's shared libraries might bring
conflicting symbols to Blender namespace at runtime.
Hopefully this doesn't break other platforms.
|
|
Need to pass -fPIC to C code as well.
Without this blosc is not being properly placement independent.
