Compositor/texture nodes: math node now allows to use pow() for
negative raising too, but only when that value is near-integer.
For other negative cases result is zero.

Fast-gauss node didn't respond to socket-input "Size" factor.
Thanks Philipp Oeser for the fix!

python functions.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.

different sizes for x/y blurring in relative mode, but choose to use aspect correction on either of the axes.
|

relative to both axes or just either width or height.

header is now by default the node type string. A custom label callback can be implemented to display more detailed information. This is currently used by group nodes, which display their internal tree name, and math, vector math, mix and filter nodes, which use their internal operation sub-type. Also the node tree selection/naming box for groups is now displayed only on open groups, to make it clearer that this is the internal type of the group and get a cleaner main tree.

types should now use the node_type_* definition helpers to initialize their bNodeType structs.
|
|
member initialization for each node, this uses a couple of helper functions now. This will make it easier to change and extend the bNodeSocket interface in the future. Two examples (normal and mapping shader nodes) included, the rest should be converted too.

*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.

inputs. These were only working with single values.

Three code fixes for 1 report. User experienced crashes while
painting on float buffer + having preview renders on.
- Texture Nodes: Image was re-allocated without using
proper thread lock
- Paint code: old convention to free the byte rect from
a float image as signal to re-create now is a proper
flag. This keeps image memory unchanged. Nice for render.
- Imbuf: call to make a byte rect from float was freeing
mipmaps unnecessary.

Texture nodes: including output node in group crashed when it got
connected. Note that this feature is not supported to do anything
else than temporarily giving an output when editing node groups.
|
|
Texture node was using the preview buffer instead of socket output buffers, which is already free'd at that point.

- move GS() define into DNA_ID.h
- add BLI_utildefines as an automatic include with makesrna generated files.
|
|
MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

Compositor: Texture Node now behaves like an image.
- Image always in render output size
- Buffer outputs RGBA and Value both supported
- Works for filter and blur and scaling too.
- Mixing 2 textures works
Implementation note:
The texture node was meant to be 'procedural', not a buffer
but a color-sample method. Unfortunately the node editor
didn't support this well, blur/filter/scale ignored it too.
For now, its better to drop this procedural concept, then
things work at least as expected. :)

OpenMP now in that case, since it's only an optimization.

combine/separate nodes.

The texture node is procedural; like RGB node it has no real buffers,
but allows per-pixel reading. The compositor uses nodes that directly
access buffers too, which conflicts with it... needs more design here.
Restored old functionality that just passes on preview size buffers
for nodes to prevent crashes. Giving it a render-size buffer is not
nice; the resolution-independence of texture nodes is interesting to
keep.
Solution could be:
- visually tag input/output sockets for this case (sockets with buffers,
vs sockets with values), so users know what to expect.
|
|
and endif() which is no longer needed.
|
|
'const char's,.
Only one functional change where Transform orientations passed "" to BIF_createTransformOrientation() which could then have the value written into.
|
|
- fixed bug in paste material, exposed by stricter warnings.
- removed/renamed various shadowed vars.
- removed BGE lamp.colour, only allow lamp.color attribute.
|
|
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.
|
|
Compositor: Texture node only allowed 1 user, with more nodes using it
there was a thread conflict, using same memory for writing values.
Also: brought back the original intention for texture nodes, which is to
be using a "procedural image", not allocating memory for a buffer, but
only allowing to read per pixel. Commit in 2007 (!) allocated full buffers
for texture nodes, without using them even.

- MSVC CFLAGS were being set by only checking WIN32, (breaking non-msvc win32 builds)

accessed by the UI at the moment, but could eventually be used for saving test-renders.
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'

ZCombine node in compositor ignored alpha values. Enabling it
would break compatibility though, so it's a tickbox option now.

resolutions
report & fix from Martin Lubich (loramel)
Use double rather then floats, this doesn't use significantly more memory (as allocating a double buffer would), other vars in this function were doubles already so may even gain some speed.

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.
|
|
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.

* non-rgba passes shouldn't use color correction
|
|
|
|
skip blur x/y when either is set to zero.
|
|
|
|
also fix memory leak.
|
|
this is because of fairly confusing logic, when an SRGB image has a float buffer added its always LINEAR, so we have to account for this elsewhere.
So the conversion from byte to float works like this:
* NONE -> NON-LINEAR
* SRGB/LINEAR -> LINEAR
...but none change the profile variable.
|
|
image node was modifying the original buffer color management, now only modify a copy.
