Currently it acts the same as set_cancel(), but this way we're able to
distinguish situations when rendering was aborted by user demand (for
example pressing Esc in standalone renderer) or if something went horribly
wrong (for example out of VRAM error).
|
|
This way for example we wouldn't wait a fortune while BVH is building after
GPU run out of memory when loading images just to see the render failure
message.

Forbid OSL from polluting current conext with obscure stuff from
windows.h, it's not useful and unhealthy anyway.
Maybe we sohuld also forbid using abbreviated Glog constants as
well tho.

Since the aligned allocation of shader closures in OSL memory pool
this workaround is no longer needed.
Also put a comment which describes the desired layout of the structure
so array of shader closures is all nicely aligned.

This solves bugs like T42210 which are caused by compiler being
smart and using some SSE instructions to operate with closure
classes, which was failing because those classes are not allocated
by the regular allocator but allocated in memory pool in OSL.
With newer versions of OSL it is now possible to force closure
classes being aligned to a given boundary and this commit uses
this new functionality.
Unfortunately, it means we're no longer compatible with older
versions of OSL, only latest git version from upstream and our
branch at github are supported:

For OSX and Windows it's not an issue because libraries are
already updated there, Linux users would need to run install_deps
script.

CPU rendering is allowed to allocate memory from multiple threads,
which means statistics need to be avare of this.

Because key == OEM_8, there no clear conversion for different keyboard layouts.
Also, we must map key to GhostKey for shortcuts.

Fixes the problem that for big sequences too many file handles were open at the same time.
Changes the playback handles that the audio sequencing code manages to be closed and reopened when needed. The metric used is the current playback position in relation to the strip. If the strip is more than 10 seconds (configurable) away from the playback cursor, the handle is released and reopened when needed.
See D915.

This patch includes the work done in the terrible consequencer branch
that hasn't been merged to master minus a few controversial and WIP
stuff, like strip parenting, new sequence data structs and cuddly
widgets.
What is included:
* Strip extensions only when slipping. It can very easily be made an
option but with a few strips with overlapping durations it makes view
too crowded and difficult to make out.
* Threaded waveform loading + code that restores waveforms on undo (not
used though, since sound_load recreates everything. There's a patch for
review D876)
* Toggle to enable backdrop in the strip sequence editor
* Toggle to easily turn on/off waveform display
* Snapping during transform on sequence boundaries. Snapping to start or
end of selection depends on position of mouse when invoking the operator
* Snapping of timeline indicator in sequencer to strip boundaries. To
use just press and hold ctrl while dragging.

The issue was noticed with gcc-4.7 (used by the release build environment)
which didn't generate optimal enough code for BVH references swap. Seems it
looked up for the assign operator for each of the reference structure members
even though nothing special was required for assignment.
Forcing compiler to use simple memory copy gives speedup of like 2-3 times.
The issue doesn't happen with OSX's clang and new gcc-4.9, but since we're
gonna to stick to gcc-4.7 for official releases for quite some time still it's
nice to have performance issues resolved for all the compilers.
Didn't put the code into #ifdef so if in the future some issues appears with
alignment or assignment which need to happen as an operator we notice this
earlier.

* Alpha Property was removed (Fix T42690)
* Some tweaks to make the panel look better again.
* Use abreviated form "Multiple Importance" everywhere, for consistency.

They were only needed for CUDA wrangler. Since we've switched to CUEW
this utility functions are no longer needed.

So now cases when object has both hair motion blur and deformation motion blur
vector pass is all correct.
We could get rid of the flag in the future, still need to look deeper into all
the areas trying to find a more clear solution.

Issue was caused by mismatch in pre/post transform matrix spaces for mesh and
curve vectors. This happened because of current way how static transform apply
works: it only stores post/pre in the world space if there's triangle motion
exists. This lead to situation when there's no triangle motion happening but
was hair motion happening.
After long time of trying to solve it in a nice way, ended up solving it in
a bit slow way -- pre/post transform is still storing in the same spaces as
they used to be stored and just convert hair pre/post position to a world
space in the kernel.
This is because currently it's not so clear how to deal with cases when curve
and mesh motion needs different space of pre/post transform (which happens in
cases when only one of the motions exists).
Would think of some magic, and meanwhile artists could be happy with proper
render results.

This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

It appears it's not really needed for convenient debugging when
using proper flags passed to the compiler. Basically, it is -g3
and set breakpoint to a function as if it's not in the namespace.
Not as if a code was any wrong, just it's possible to have more
clear solution for the issue i've tried to solve in the past.

Caused by D643, in fact we need to get the visualInfo before creating the window.

This doesn't have noticeable affect on the render times, but avoids possible
numerical issues.

The issue lies in the FMA functions, so disable them on Windows for now.

The idea is to avoid memory allocation when only one segment step is to be allocated.
This gives some speedup which is difficult to measure on this trashcan from hell, but
it's about from 7% to 10% in the extreme case with single volume filling the whole of
the viewport. This seems to depends on the phase of the bug-o-meter in the studio.
On the linux boxes it's not that spectacular speedup, it's about 2% on my laptop and
about 3% on the studio desktop. This is likely because of the awesomeness of jemalloc.
|

This won't give any big speedup,
just avoids redundant sqrtf and may be useful in future.

Add compile-time check for particular glibc version which fixed the issue.
This makes it so own-compiled blender is the fastest in the world, and the
only issue remains what should we do for release builds.
After some discussion with Campbell we decided to keep it as is for now
because slowdown is not that much noticeable. We'll disable this workaround
for release builds when all the majority of the distros will switch to the
new version of glibc.
