This commit contains all the remained parts needed for initial integration of
OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU
backends which works in the following way:
- When SubSurf modifier is the last in the modifiers stack then GPU pipeline
of OpenSubdiv is used, making viewport performance as fast as possible.
This also requires graphscard with GLSL 1.5 support. If this requirement is
not met, then no GPU pipeline is used at all.
- If SubSurf is not a last modifier or if DerivesMesh is being evaluated for
rendering then CPU limit evaluation API from OpenSubdiv is used. This only
replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG
structures exactly the same as they used to be for ages now.
This integration is fully covered with ifdef and not enabled by default
because there are several TODOs to be solved first:
- Face varying data interpolation is not really cleanly implemented for GPU
in OpenSubdiv 3.0. It is also not implemented for limit evaluation API.
This basically means we'll have really hard time supporting UVs.
- Limit evaluation only works with adaptivly subdivided meshes so far, which
basically means all the points of CCG are pushed to the limit. This gives
different result from old code.
- There are some serious optimizations possible on the topology refiner
creation, which would speed up initial OpenSubdiv mesh creation.
- There are some hardcoded asumptions in the GPU and DerivedMesh areas which
could be generalized.
That's something where Antony and Campbell can help, making it so the code
is structured in a way which is reusable by all planned viewport projects.
- There are also some workarounds in the dependency graph to make sure OpenGL
buffers are only freed from the main thread.
Those who'll be wanting to make experiments with this code should grab dev
branch (NOT master) from
https://github.com/Nazg-Gul/OpenSubdiv/tree/dev
There are some patches applied in there which we're working on on getting
into upstream.

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode
Viewport
* Cameras
* Plane
* Volume
Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support
Sequencer
* Image/Movie Strips 'Use Multiview'
UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Original patch by @random (D765) with some minor work done by @campbell
and me.
At this place, I'd like call out a number of people who were involved and
deserve a big "Thank you!":
* At the first place @randon who developed and submitted the patch
* The Blendercn community which helped a lot with testing - espacially
* @yuzukyo, @leon_cheung and @kjym3
* @campbellbarton, @mont29 and @sergey for their help and advises during
* review
* @ton who realized the importance of this early on and asked me for
* reviewing
We are still not finished, as this is only the first part of the
implementaion, but there's more to come!

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

- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.
|
|
|
|
* at max 10 cache items will be available. Items will be removed by
latest usage.
* number of cached items can be adjusted in code
* added deinitialization of compositor when blender exists.
* updated scons and cmake build files

Not all file formats/calls are supported yet. It will be expended.
Please from now on use BLI_fopen, BLI_* for file manipulations.
For non-windows systems BLI_fopen just calls fopen.
For Windows, the utf-8 string is translated to utf-16 string in order to call UTF version of the function.

also rename backface_culling --> use_backface_culling (which is used elsewhere in rna)
|
|
|
|
|
|
|
|
remove missing includes and use more strict formatting.

which checks for correctness in our files.
|

blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
|
|
anything, only contained a hash map and functions to pass command line args
to the game engine. Moved those to container and BlenderRoutines modules.

Nothing is changed by default but some linux distributions want to have executing python be opt-in.
This keeps the same functionality but disables auto-run from factory settings and in background mode unless its enabled as a command line argument.
This CMake option is marked as advanced and wont show in the regular options list so its less likely to be enabled by people that like to turn everything ON without reading descriptions :)

own glew library.
|
|
*nix with non-standard libjpeg/png/zlib locations was broken.
in the case of python this makes it easier to move to find_package(PythonLibs) when 3.x is supported.

and endif() which is no longer needed.
|
|
quicktime & sndfile options.
|
|
reporting missing headers & C files.
this is important so IDE's using CMake integration always get blender headers. - QtCreator & MSVC for eg, probably others too.
|
|
- MSVC CFLAGS were being set by only checking WIN32, (breaking non-msvc win32 builds)

by cmake devs.
globbing vs explicit is discussed here.
http://www.cmake.org/pipermail/cmake/2008-December/025694.html
Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.
|
|
- use list append in more places.
- remove non existing include dir.
|
|
- remove some unused include paths
- remove unused linux path define
|
|
Still getting error:
Warning: .drectve `/DEFAULTLIB:"LIBCMT" /DEFAULTLIB:"OLDNAMES" ' unrecognized

enabled). Also fixed cmake so buildinfo works.
Note to all:
** Please mention the revision number when making a bug report **
|
|
GLEW update to version 1.5.1 [11-03-08]
this opens room for Geometry Shader support.
* - Brecht, Campbell told me you did some local changes in order to make it right in Linux. I get to you in order to know what those changes are (or feel free to commit them directly)

COLLADA code is disabled by default (it has dependencies requiring manual install).
SCons and CMake builds are supported on Windows and Linux, no Mac building yet. More on building COLLADA code: http://wiki.blender.org/index.php/User:Kazanbas/Building_Collada_Branch.
