This does not include all the struct and type renaming. Only files were
renamed.
gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h

Fixes constant shader and texture rebuilding when doing animation playback
with multiple editors that use different view transforms.
|

There is no need for it now that we use opengl 3.3. Use GL_RGBA16F instead.
|
|
|
|
Also remove textureSize() replacement code, is always supported now.

small part of ongoing OpenGL upgrade

We cannot have version130 there (should use version 330 instead).

The Issue
=======
For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.
Why Remove
==========
One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch
If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.
For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3
Fixes T51301

This eliminates tons of glGetUniformLocation calls from the drawing loop. Vast majority of code can keep making the same function calls. They're just faster now!
- Batch_Uniform*
- immUniform*
- gpuBindMatrices
- and others

Quite handy for debugging.
Unfortunately, this doesn't support viewport tweaks yet since those
require GLSL for colorspace conversion. Maybe this will be implemented
as well one day in the future..
|

Was a ground work for some more improvements here, but got dragged
to some other studio maintenance job here.
The plan would be to enable exposure/gamma control for fallback mode
which will definitely be really handy for development and might be
handy for cases when OCIO config can not be read.

Windows"
White the config itself could be loaded this way, lookup tables can not. Additionally,
that's not really clear how to solve the issue with search path which is multi-byte
only in the API.
Reverting for further investigation.
This reverts commit ab4307aa0868f2d8389cc0dd500eff38909b08f1.

Those warnings are trigerred by stl classes in OCIO's public interface.
To quote MSDN: "C4251 can be ignored if you are deriving from a type in
the Standard C++ Library"
This is the only instance where those warnings hunts us, so for now we
can keep it all local in intern/opencolorio but this might be changed
in the future.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

Mostly glBlendFunc related.

The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.

We queried the wrong value when looking for the bound 2D texture. This
is not totally robust because currently bound texture may not be a 2D
one, but this should work for now.

Separates graphics context creation from window code in Ghost so that they can vary separately.

The GLSL function textureSize() is not supported here, only when we start using
OpenGL core profile will this work. For now check the supported GLSL version and
use a somewhat slower replacement.
|
|
Summary:
Uses some magic pseudo-random which is actually a
texture coordinate hashing function.
TODOs:
- Dither noise is the same for all the frames.
- It's different from Floyd's dither we've been
using before.
- Currently CPU and GPU dithering used different
implementation. Ideally we need to use the same
dither in CPU.

Summary:
Version of those libraries might be useful to know.
- OIIO and OCIO is exposed via bpy.app.oiio and bpy.app.ocio.
There're "supported", "version" and "version_string" defined
in those modules.
- OSL is available as _cycles.osl_version and _cycles.osl_version_string.

report by email and patch by Benoit Bolsee
"It is a basic compilation bug (variable defined in a c file and declared
in the c++ file: name decoration will change the name in the c++ file
and the linker will not find it)"

The title says it all, now having curve mapping
enabled in color management settings wouldn't
force fallback from GLSL to CPU based color space
conversion.
|
|
Also made libmv-capi use guarded objetc allocation.
Run into some suspecious cases when it was not so
clear whether memory is being freed or not.
Now we'll know for sure whether there're leaks or not :)
Having this macros in a guardedalloc header helps
using them in other areas (for now it's OCIO and libmv,
but in the future it'll be more places).

This commit implement's OCIO's Looks idea which
is about applying some color correction on the
buffer before it get's affected by a display
transform.
This is mainly used to modify images in an
artistics way.
Currently we've got looks generated from film
response curves for all sorts of cameras.
Patch by both of me and Brecht.

Also extend 3DLUT edge size to 64 (1 meg of memory) to increase

Previous GLSL code had error, the if() statement had to be negated.

Previous version worked, now a version with simplifying this GLSL code.

There's no logical reason I can find... but I commit it because many others have
the same error, so we can check.
