Shutter curve now can be controlled using curve mapping widget in the motion
blur panel in Render buttons. Only mapping from 0..1 by x axis are allowed,
Y values will be normalized to fill in 0..1 space as well automatically.
Y values of 0 means fully closed shutter, Y values of 1 means fully opened
shutter.
Default mapping is set to old behavior when shutter opens and closes instantly.
This shutter mapping curve could easily be used by any other render engine by
accessing scene.render.motion_blur_shutter_curve.

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

Summary:
Mainly addressed to solve old TODO with color managed fallback
to CPU mode when displaying render result during rendering.
That fallback was caused by the fact that partial image update
was always acquiring image buffer for composite output and was
only modifying display buffer directly.
This was a big issue for Cycles rendering which renders layers
one by one and wanted to display progress of each individual
layer. This lead to situations when display buffer was based on
what Cycles passes via RenderResult and didn't take layer/pass
from image editor header into account.
Now made it so image buffer which partial update is operating
with always corresponds to what is set in image editor header.
To make Cycles displaying progress of all the layers one by one
made it so image_rect_update switches image editor user to
newly rendering render layer. It happens only once when render
engine starts rendering next render layer, so should not be
annoying for navigation during rendering.
Additional change to render engines was done to make it so
they're able to merge composite output to final result
without marking tile as done. This is done via do_merge_result
argument to end_result() callback. This argument is optional
so should not break script compatibility.
Additional changes:
- Partial display update for Blender Internal now happens from
the same thread as tile rendering. This makes it so display
conversion (which could be pretty heavy actually) is done in
separate threads. Also gives better UI feedback when rendering
easy scene with small tiles.
- Avoid freeing/allocating byte buffer for render result
if it's owned by the image buffer. Only mark it as invalid
for color management.
Saves loads of buffer re-allocations in cases when having
several image editors opened with render result. This change
in conjunction with the rest of the patch gave around
50%-100% speedup of render time when displaying non-combined
pass during rendering on my laptop.
- Partial display buffer update was wrong for buffers with number
of channels different from 4.
- Remove unused window from RenderJob.
- Made image_buffer_rect_update static since it's only used
in single file.

internal viewport rendering. Lots of tweaks here, mainly:
* Stop 3D viewport render and free database before undo.
* Accumulate update flags rather than replace them each time it rerenders, to
avoid previous updates getting lost.
* Don't check against Render struct view parameters for changes, those are set
in the job thread which might not run before the next update call.

Because of our release soon, feature has been added behind the Debug Menu.
CTRL+ALT+D and set it to -1. Or commandline --debug-value -1.
When debug set to -1, you can put the viewport to 'render' mode, just like
for Cycles. Notes for testers: (and please no bugs in tracker for this :)
- It renders without AA, MBlur, Panorama, Sequence, Composite
- Only active render layer gets rendered. Select another layer will re-render.
- But yes: it works for FreeStyle renders!
- Also does great for local view.
- BI is not well suited for incremental renders on view changes. This only
works for non-raytrace scenes, or zoom in ortho or camera mode, or for
Material changes. In most cases a full re-render is being done.
- ESC works to stop the preview render.
- Borders render as well. (CTRL+B)
- Force a refresh with arrow key left/right. A lot of settings don't trigger
re-render yet.
Tech notes:
- FreeStyle is adding a lot of temp objects/meshes in the Main database. This
caused DepsGraph to trigger changes (and redraws). I've prepended the names
for these temp objects with char number 27 (ESC), and made these names be
ignored for tag update checking.
- Fixed some bugs that were noticable with such excessive re-renders, like
for opening file window, quit during renders.

* Made Freestyle optional (turned on by default).
* Fix for missing bpath.c updates in the previous merge of trunk changes.

Added a set of stroke geometry modifiers to the Geometry tab of line styles
in the Parameter Editor mode. Now the following stroke geometry modifiers are
available, each with a set of animateable parameters:
- Sampling: changes the resolution of stroke backbone polylines.
- Bezier Curve: replace stroke backbone with a Bezier approximation of the
stroke backbone.
- Sinus Displacement: add sinus displacement to stroke backbone.
- Spatial Noise: add spatial noise to stroke backbone.
- Perlin Noise 1D: add one-dimensional Perlin noise to stroke backbone.
- Perlin Noise 2D: add two-dimensional Perlin noise to stroke backbone.
- Backbone Stretcher: stretch the beginning and the end of strokes.
- Tip Remover: remove a piece of stroke at the beginning and the end of strokes.
To branch users: When you have a .blend file with Freestyle options specified,
you may want to add a Sampling modifier with the 'sampling' value set to 5.
This value specifies a resolution of polylines for line drawing in Freestyle.
If no sampling modifier is specified, your line drawing will result in coarse
polylines. Before geometry modifiers were introduced, this initial sampling
was automatically done. Now the initial sampling is a tunable parameter that
can be omitted, allowing better control on polyline resolution.

modifier boxes in the Parameter Editor mode UI.
|
|
A number of UI elements were newly introduced to control line color, alpha
transparency and line thickness by means of base color/alpha/thickness plus
modifiers that alter the base values. To begin with, three basic modifiers
were prototyped with the aim of putting the new UI framework in practice
and evaluating if it works properly.
The Parameter Editor mode is still in a work-in-progress state and totally
useless from users' viewpoint.
|
|
This commit is just meant to give the new GUI framework a concrete shape.
There is no usefulness in newly introduced elements at the moment.
Freestyle options in render layers now include a pull-down menu named Control
Mode that allows you to choose either the Python Scripting or Parameter Editor
mode. The Python Scripting mode is the conventional way of controlling
Freestyle by directly using style modules written in Python. The Parameter
Editor is a new control mode that is intended to be used by everyone without
relying on Python programming.
In the Parameter Editor mode, you can specify multiple line sets for each
render layer. A line set defines feature edge selection criteria, as
well as a line style for drawing the selected feature edges using specific
line stylization parameters. Line style is a new datablock type, meaning
that a line style can be shared by multiple line sets (possibly those in
different render layers in different scenes).
Much more additions are anticipated in subsequent commits to implement UI
controls for specifying feature edge selection criteria and line stylization
parameters.

* Fixed up RNA and UI
* Brought back 'Save' and 'Clear' operators (in the little triangle menu in
environment map properties)
* While I was at it, noticed that environment maps were only using 8bit
colour, changed it to use full 32bit float instead for proper HDR colour etc,
so environment map reflections have the correct colour range

Blender 2.5. As of I right now, Freestyle is back in the UI, but rendering still fails because of the texture manager.

Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
