This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

This patch introduces a couple new stroke modifiers. The ones currently implemented are based on prototypes by @kjym3 and myself.
The new modifiers:
- Tangent
- Thickness noise
- Crease Angle
- Simplification
- Curvature 3D
The documentation for these new modifier types can be found [[ http://www.blender.org/manual/render/freestyle/parameter_editor/index.html | in the manual ]]:

The reported issue was caused by a backward incompatibility due to careless
code changes made when per-material Freestyle line colors were introduced
in rB7915d7277ac8c605f016f30f943080556244fb59. In 2.71 line style
Material color/alpha/thickness modifiers was retrieving alpha transparency
from Material.alpha, whereas in 2.72 Material.line_color[3] was referenced.
The present fix reverts the aforementioned code changes.
This issue is a regression from 2.71, so the fix is appropriate for inclusion in
the 2.72a release.

The following two sort keys are added for sorting chains.
* Projected X - Sort by the projected X value in the image coordinate system.
* Projected Y - Sort by the projected Y value in the image coordinate system.
A new line style option for the selection of first N chains is also added.
Moreover, the chain sorting and chain selection operations are now executed
in this order instead of the reverse order used previously. The UI has also
changed accordingly. This functional change is backward compatible and
won't result in visual differences.

New properties 'line_color' and 'line_priority' are added to Material ID data blocks.
The 'line_color' property allows users to specify a per-material line color that can be
used as a Freestyle line color through Material color modifiers of line style settings.
The new line color property is intended to provide a solution for line color
stylization when a proper Freestyle support for Cycles is implemented (likely
as part of the upcoming Blender 2.72 release; see Patch D632). Materials in
Cycles are usually set up using shader nodes, and Freestyle won't be capable
of retrieving colors and other properties from node-based materials any soon.
The new line color property of materials addresses this foreseen limitation by
providing artists with an intuitive alternative mean to specify line colors on a
per-material basis independently from node trees.
The 'line_priority' property gives users a way to control line colors at material
boundaries. When a line is drawn along a feature edge at material boundaries,
one of the two materials on both sides of the edge has to be picked up to
determine the line color. So far there was no way to control this selection
(which was in effect at random). Now the material with a higher line color
priority will be selected.
The new per-material line settings are shown in the new Freestyle Line tab in
the Material context of the Properties window (only when Freestyle is enabled).

Line styles now have a set of new options for rearranging the stacking order of lines.
This gives artists more control to determine which lines should be drawn on top of others.
Two available sort keys are the distance from camera and curvilinear 2D length.
Since the distance of a line from camera may vary over vertices, another option called
integration type is used to compute the sort key for a line from the values computed at
individual vertices. Available integration types are MEAN, MIN, MAX, FIRST and LAST
(see the tool tips for more detail).

* Split and moved Cycles’ render layers panels into the render_layer
context as well (would be nice to hide this context when not needed,
e.g. with the BGE, but this is not so easy to do nicely...).
* Fixed some inconsistencies with trunk (probably due to svn merge
glitches) using r52858 as reference. Also recovered the missing
release/bin/blender-softwaregl file.
* A bunch of style code fixes in Blender's own code (not Freestyle
itself yet): line lengths, spaces around operators, block formatting,
headers, etc. In rna_linestyle.c, color_blend_items was replaced by
ramp_blend_items (exported from rna_material.c).

RNA subtype), since Freestyle internally use angles in radians.
A patch set by Bastien Montagne (many thanks!)
NOTICE FOR BRANCH USERS:
This commit may break line drawing settings of already saved Freestyle files.
All angles are now treated as radians instead of degrees, so collections of
angle values might be necessary in order to recover previous visual results.
Affected properties are:
- Crease Angle in the edge detection options
- Min 2D Angle in the 'Splitting' section of a line style
- Max 2D Angle in the 'Splitting' section of a line style
- 'orientation' parameter of the Calligraphy thickness modifier
- 'angle' parameter of the PerlinNoise1D geometry modifier
- 'angle' parameter of the PerlinNoise2D geometry modifier
- 'angle' parameter of the 2DTransform geometry modifier

when combined with geometry modifiers.
The problem is that users were not able to choose the time when the
dashed line options are applied. Instead, the dashed line options were
applied only before geometry modifiers were employed. Since dashes were
separate strokes, the geometry modifiers were processed dash by dash.
Depending on users' artistic intention, this may or may not lead to
expected stylization results, as reported by octane98 in the
BlenderArtists Freestyle thread on January 3, 2012.

Now the Strokes tab of the Freestyle Line Style panel has two sets of
dashed line options. One is in the Splitting section of the Strokes tab
and used for splitting strokes by dashed line patterns. The other set
is called "Dashed Line" and used to generate dashed lines based on the
strokes after the geometry modifiers are applied. The two sets of
dashed line options are independent of each other, so that users can
enable one of them as well as both at the same time.

stroke thickness.
The new options enable a better control on the position of stroke thickness with
respect to stroke backbone geometry. Three predefined positions are:
* center: thickness is evenly split to the left and right side of the stroke geometry.
* inside: strokes are drawn within object boundary.
* outside: strokes are drawn outside the object boundary.
Another option called "relative" allows users to specify the relative position by a
number between 0 (inside) and 1 (outside).
The thickness position options are applied only to strokes of the edge types SILHOUETTE
and BORDER, since these are the only edge types defined in terms of object boundary.
Strokes of other edge types are always using the "center" option.

that produces a blueprint using circular, elliptic, and square contour strokes.
Related changes and bug fixes were made as follows:
* The randomness in radius and center has been transformed into optional
parameters of the pyBluePrintCirclesShader and pyBluePrintEllipsesShader.
Also a new optional parameter to control the randomness of backbone
stretching has been added to the pyBluePrintSquaresShader.
* A bug in the pyBluePrintSquaresShader that invisible stroke vertices at
corners of rectangular contour strokes were not properly drawn. The problem
was due to the changes of the / operator between Python 2.x to 3.x. Even
when the two operands of the division operator are integers, Python 3.x
gives a floating-point number when the quotient is not an integer. The fix
was just to replace the / operator by the // operator for integer division.
* An unpleasant discontinuity in circular and elliptical contour strokes
was fixed.
* The length parameter of the Backbone Stretcher geometry modifier has been
renamed to `backbone_length' in line with the parameter of the same name in
the pyBluePrintSquaresShader.

New there are only two chaining types: plain and sketchy. Both chaining types
have the "same object" option. With this option enabled, only feature edges of
the same object are chained. The sketchy chaining also has the "rounds" option
to specify the number of rounds in a sketchy multiple touch.
Also removed a temporary workaround (implemented by means of a custom chaining
rule) for infinite straight lines, which has resulted in much cleaner strokes.
|
|
The default chaining option is now called "Natural", while the new chaining options
are "Sketchy: Topology Preserved" and "Sketchy: Topology broken". The latter two
options allow for generating chains of feature edges with a sketchy multiple touch.
The "Sketchy: Topology Preserved" option takes account of the topology of objects
in the view map, while the "Sketchy: Topology broken" ignores the edge topology.
The "rounds" option specifies the number of rounds in sketchy strokes.

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.

Most stylization parameters in line style datablocks are now
animatable by means of keyframes. Right click on a line
style parameter, and you will see a list of keyframe-related
commands in the context menu.
Concerning the implementation, RNA path resolution has been
extended to properly address color ramps in line style color
modifiers. File I/O has been also improved to load/save the
animation data associated with line style datablocks.
Known issue: Freestyle-related options in render layers are
not animatable at the moment, because of general inability (or
maybe a bug) that keyframes cannot be inserted with respect to
render layer options.

* Added more curve blend types. The default is set to "MIX".

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.
