Robin (Frrr) Allen did a decent job on this, so we can also welcome him
as a member in the svn committers team to maintain it!
I do the first commit with some minor fixes:
- get Makefiles work
- fix rounding issue with tiles on unit faces
- removed UI includes from tex node
A nice doc in wiki is here:
http://wiki.blender.org/index.php/User:Frr/TexnodeManual
On the todo for Robin is:
- When using one or more Texture-input nodes, you cannot edit them by activating
(as works now for Material nodes).
- The new "output node" option fails on the default case, when only one
output node is active. It then shows often a blank menu. Will get fixed asap.
- When using a NodeTree-Texture as input node, the menu for 'active output'
should not show. NodeTree should ignore other nodetrees to keep things sane
for now.
- On a future todo is proper usage of "Dxt" and "Dyt" texture vectors for
superior antialising of checkers/bricks.
General note; I know people are dying to get a full integrated shader system
with nodes. In theory we could merge this with Material Nodetrees... but I
rather wait for a solid and very well thought out design proposal for this,
also including design ideas for unifying with a shader language (GPU, CPU).
For the time being this is a nice extension of current textures. :)

This can be useful for toon shading etc.

code, causing the "SamplesY" button to overlap others.
|
|
Image counter can be set to zero when unlinking images, whilst they can
be in use for texture. This is a temporary solution to prevent errors!
(Now image unlinking doesn't set zero users anymore)

buffer shadow didn't update the viewport correct.
|
|
- removed ugly clamping function (it was dividing XYZ based on max of
one of the values)
- added option to use Exposure, this only works for brightness (Y).
results look very pleasant, foggy and hazy results are possible.
with exposre==0, no exposure happens for HDR extreme range skies,
this is how yafray rendered it.
- added menu for choosing color spaces (CIE = modern lcds)
Please review! (and yes i know it's still not in World :)
|
|
- Area lamp with 1 sample still used an offset for the first sample
- Sample buttons were not visible for area without shadow.
|
|
Takes half an hour to find a nice empty spot for a button! Another attempt
to locate new shadow color swatch. Now back in shadow panel, bottom.
|
|
- Button for 'shadow color' was drawn over 'layer shadow' button...
The shadow+spot panel was cramped... spot shadowbuffer uses all
space. Moved it to the Lamp panel with label, more clear now.
Panel reorg is for later :)
- Small fix: Area Lamp 'gamma' slider didn't update preview.
Unfortunately had to move this slider to smaller button...
|
|
- Added blending mode and factor option, so it's more clear and
controllable what happens with it. Also nice for crazy effects
of course!
- Preview render now shows preview for it too
On the todos:
- have this in World buttons (as well) for quicker sky setups
- review math of color clamping and scaling, this is definitely
not good... but a fix will make old files look very different.
|
|
Finally, after a long time new render candy for the non-game peoples! :)
Good doc is here: (url splits in two)
http://www.harkyman.com/2008/08/06/controllable-shadow-intensity-
and-color/
Note the colorpicker for shadow is in "Shadow and Spot" panel. A bit
hidden, could get more attention. For later. :)

3d window didn't refresh correctly when loading a new background image.
Fix by Ken Hughes. :)

the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.

- Changed some tooltips.
- Refresh with reactors and shared particle settings.
- Copying of child particles.

For larger architecture environments it was proved to be necessary.

tooltip patch from olivs - [#10218] Corrected a few tooltips in shading buttons
|
|
|

(not the directory name) to fix bug [#10566] File Open Dialog replaces '#' with '0' in directory names.
removed frame numbering from BLI_convertstringcode into its own function (BLI_convertstringframe), many uses of BLI_convertstringcode were passing dummy frames values anyway.
in cases where adding the current frame number to a filename is needed run BLI_convertstringframe(...) after BLI_convertstringcode(...)
There are some cases Im not sure BLI_convertstringframe is needed, these have been commented as todo, but at least have the same functionality they used to.

act as if the object was in its original position, instead of being
different for all instances. However, this is desired behavior in
some cases and so breaks compatibility. Now it only does the new
behavior when enabling the "From Original" option.

-Particle texture calculations weren't using the mtex->def_var properly
-Texture buttons didn't set proper update flags for hair

But not sure exactly what the user is doing.
Made game logic work on linked objects and disabled "Add Material" for linked mesh data.

shadowbuffers. At the time the results were not satisfying enough,
but we now suffer a shadow problem that might well be solved with
this feature.
Problem:
Temporal aliasing of shadowbuffers when small details move (like strands).
In this case it doesn't work to simply increase the shadowbuffer size,
because strands are pixel-sized. Huge shadowbuffers make strand shadows
almost disappear. So... the shadowbuffer resolution has to be not too high.
Instead of increasing the buffer size, we then create multiple buffers,
each on different subpixel positions (a bit like "FSA" :).
So! Shadowbuffer sampling then works as follows;
1) You take multiple samples in the shadowbuffer, on different locations
inside (or around) the rendered pixel.
That option was aready available as "Samp" button in Lamps
2) Set amount of sample buffers. It is default 1, but can be 4 or 9.
The results of setting it to '4' or '9' buffers you can see here:
http://www.blender.org/bf/filters/index3.html
Actually, deep shadowbuffers could solve it probably too! Anyhoo...
|

New option "move texture channel up/down" lacked redraw calls.
Featurette:
There's still no manipulator handles for lamps to set cone size, dist,
clipping. To save our poor Peach artists hours of work I've added a
quick method to at least be able to do it interactive.
Option is hidden behind Wkey, and uses a similar function like Scaling.
(Put mouse cursor close to start value, move mouse to center of lamp)
Ultimately this should move to custom manipulator handles...

Also a patch from Markus Schulz that
adds buttons to the material, light, and world texture panels to make it
easy to rearrange the textures in the list without having to
use copy and paste.

Reversion of premul bugfix, as it was apparently not
working all that well.
Note that this brings back the bug where the erase alpha
paint tool won't display correctly, since the UV image
editor just draws images in key alpha now.
|
|
in the commit log. Couldn't get this to work well, probably this would
work a lot better with the IBL spherical harmonics feature, so I've just
disabled the option in the interface for now.
|
|
(which basically tells the renderer and compositor to expect a
key image) is now done at the image user level.
This does have some caveats, as image users don't always work
the way I thought they would/should (for example, the same image user
structure is apparently used in the uv image editor for all images,
which is kindof odd).
The UV image editor also now smartly detects if the premul option is
set and draws the image using key alpha, instead of premul
The subversion level was upped to convert the old premul flag, which was at
the image level, to the new one, which is at the image user level.

are not updated
- Material buttons code didn't set particles update flag
- Small change to how particle emit time is interpreted from textures, now the "time" texture output can actually be used for something
|
|
making local objects with a dupligroup didnt disable the indirect flag, also made the tool respect visible and restricted flags.
|

This completes the pipeline make-over, as started in 2006. With this
option, during rendering, each sample for every layer and pass is being
saved on disk (looks like non-antialiased images). Then the composite
and color correction happens, then a clip to 0-1 range, and only in end
all samples get combined - using sampling filters such as gauss/mitch/catmul.
This results in artefact-free antialiased images. Even Z-combine or
ID masks now work perfect for it!
This is an unfinished commit btw; Brecht will finish this for strands.
Also Halo doesnt work yet.
To activate FSA: press "Save Buffers" and the new button next to it. :)

world. That allows more extreme lamps (areas too).
To make it work more intuitive, the preview renders in buttons now use
the settings for exposure too.
|
|
This is actually just the alpha value as currently being calculated
by the mist code. It is in many cases not very useful to have this as
alpha in shading result, also for postprocess and composite.
Note: this pass also works with "Mist" not set in World, of course.

=============================
A new approximate ambient occlusion method has been added, next to the
existing one based on raytracing. This method is specifically targetted
at use in animations, since it is inherently noise free, and so will
not flicker across frames.
http://www.blender.org/development/current-projects/changes-since-244/approximate-ambient-occlusion/
http://peach.blender.org/index.php/approximate-ambient-occlusion/
Further improvements are still needed, but it can be tested already. There
are still a number of known issues:
- Bias errors on backfaces.
- For performance, instanced object do not occlude currently.
- Sky textures don't work well, the derivatives for texture evaluation
are not correct.
- Multiple passes do not work entirely correct (they are not accurate
to begin with, but could be better).
|
|
Lampbuffers require painful bias tweaking (to prevent aliasing or to
get shadow detail). Sometimes you want this different per object, like
for gras you want less shadow detail, but for the ground you want high
detail. This feature allows to tweak it.
The new "LBias" slider is in shader panel, bottom. Ugly! But, thats for
later...

is not being reset when you render, so after render the layer you picked is
still visible in Image Window.
