f11f6d179e Fix for compositor node preview sizes: Use the render output aspect ratio for estimating the required preview rect size instead of assuming a square, to avoid wasted space. Note that this does not work for newly added nodes until they have first been evaluated and a preview image has been generated (same behavior as before pynodes merge and associated preview changes). 2013-03-22 08:50:56 +00:00

4638e5f99a Merge of the PyNodes branch (aka "custom nodes") into trunk.
PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.

=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.

Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].

=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].

The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

a73dd3476e Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.

This introduces two configurable color spaces:

- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).

  This setting could be found in image/clip data block settings.

- Display color space which defines space in which particular display is working.

  This settings could be found in scene's Color Management panel.

When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.

This conversions are:

- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.

- Exposure affects on image exposure before tone map is applied.

- Gamma is post-display gamma correction, could be used to match particular
  display gamma.

- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.

All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.

This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).

Some technical notes:

- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.

- Space of byte buffer is stored in image buffer's rect_colorspace property.

- Profile of image buffer was removed since it's not longer meaningful.

- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.

- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.

- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.

Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO
integration and to Brecht van Lommel for some further development and code/
usecase review!

d4be0ec9fb * there is a tiny memory leak. I think it happens when you quit blenden
during a WM_draw. tiny is max 8* size of pointer and it is maintained at
that size. So no worries there.
 * cleanup some code to be certain that deinitialization happens
correctly.

error prints or even crashes for poor OpenCL implementations when not using it.

e28fcec042 Fix for [#32220] regression - DistortionCache is never freed.
* 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

778999cbbf Two pass execution:
1. first pass only fast nodes are calculated and only to the active
viewer node
2. second pass all nodes to all outputs

Temp disabled highlights because of random crashes.
