Support UV Map nodes for determining active UV layer. Now when an image
node is enocuntered, the system will recursively search the node's input
sockets for any UV Map nodes. Obviously this won't fetch any coordinate
transforms into painting, and it will only choose the first UV Map node
encountered if more than one UV Map nodes are combined.
However it should allow custom UV setups per materials and tweaking of
the UV Map node's UV layer from the Slots panel.

This is a per-strip option next to the build proxy size which tells blender
whether to skip building proxy size if the file for it already exists or not.
The option is called "Overwrite" for simplicity.
This option is enabled by default to avoid changes in the file behavior.
TODO: Would be nice to do something like that for movie clips as well.

based on the interpolate property does not make any sense at all.
These settings are still totally confusing - this code has not been
touched since 2009 at least! Go figure ...

The logic used for determining whether certain keyframing settings (i.e. visual,
only needed, xyz -> rgb) got applied was wonky. The original intention here was
that the Keying Set settings would override the global settings, and the path
settings would override what was used for the Keying Set. However, that was not
happening in all cases previously, as it was only possible to add flags and not
to turn them off.
This commit fixes that by introducing separate toggles to control whether the
Keying Set/Path's settings override the settings inherited from its parent
(i.e. the Keying Set for the Path, and the User Prefs for the Keying Set).
The icons used for these toggles could get revised a bit (we need something
which communicates "override this"; the current one is the closest I could find)
WARNING: If you have old keying sets, this may cause some breakage!

was cancelling when the dynamic range was zero, but gave odd behavior,
using the last value, not the values from the UI.

Since 1c3f2354f83b3e79dee31d837ca4d7c08d2c3f26 the keyframing settings on
Keying Sets have been incorrectly displayed as a clump of toggle buttons,
which are usually only used when only one of the options apply.
Reverting this back to how it was, while leaving bl_options in place still for
the one case where it makes sense to do it that way (i.e. for KeyingSetInfo)

Alt+Mousewheel was used for frame scrubbing which isn't really good as users
may often use this by accident while using Alt for Viewport navigation.
Frame scrubbing/frame_offset() is now called by Ctrl+Alt+Mousewheel (shift +
Mousewheel was already used for scrolling up/down)

Recent addons commit meant that addons would be enabled even if they weren't found.
This would give an error (which is fine), but also remove from preferences.

These were used as UI buttons during development. If such parameters are
needed again later they should instead be added in the (now global)
SimDebugData and made accessible with a dev addon or so.

Note differences in those five icons are invisible by eye, just for sake of consistency.

Name each icon group from its define in Blender.
Simplifies searching for a given icon (in one way or the other), and could also be
useful one day in some scripting.
Also, removed/fixed more empty and stray groups...
Finally, found that we have several svg icons not linked to any defines, and one define
with no icon (dyntopo), would be nice to sort this one way or the other too.
|
|
Made sure each icon has its own, 'private' group.
Removed empty groups, and some stray paths and rects (among other benefits,
'make icons' do not generate anymore that half o dozen of empty icons one had to remove
by hand before committing ;) ).
Note: double checked, only five generated icons differ (on binary level) from before,
with no actual visual diff.

This is BAD code, but the particle kinking does not make it easy to
write a non-local modifier that requires neighboring positions,
curvature, etc. The feature is needed for Gooseberry.

This adds another level of clumping on child hairs. When enabled, child
hairs chose a secondary clumping target using a Voronoi pattern. This
adds visual detail on a smaller scale, which is useful particularly when
the number of parents is relatively small.
Natural fibres behave in a similar way when they become sticky and
intertwined. Hairs close to each other form a first twisted strand, then
combine into larger strands. Similar features can be found in ropes:

Scope update is very slow for high resolutions, and currently blocks
the UI thread(!). This is especially terrible in paint modes, where
each stroke causes a scope update and unacceptable freezing.
The scopes update method tries to avoid this somewhat by skipping if the
toolbar is disabled, but this doesn't help when painting where brush
tools etc. are frequently needed. It's also a bad-level poll, with the
core system accessing a UI element.
Eventually scope updates should become a low-priority background job,
as well as becoming threaded. Until then this polling provides a usable
workaround to the most outrageous cases.

This is an alternative method to the current fixed function with a
clump factor and "shape" parameter. This function is quite limited and
does not give the desired result in many cases (e.g. long, parallel
rasta strands are problematic). So rather than trying to add more
parameters there is now a fully user-defined optional curve for setting
the tapering shape.

This is necessary because the hair dynamics settings are not part of the
ParticleSettings datablock, but part of the convoluted cloth modifier
inside the particle system struct. In the future this will be recoded
properly, but in the meantime presets provide a simple an unobtrusive
way to have reusable dynamics settings for hair.

This helps to create some variation in a hair system, which can
otherwise become very uniform and boring. It's yet another confusing
setting in a system that should have been nodified, but only option for
now (broken windows ...)

This allows setting a target density which the fluid simulation will
take into account as an additional term in the pressure Poisson
equation. Based on two papers
"Detail Preserving Continuum Simulation of Straight Hair" (McAdams et al. 2009)
and
"Two-way Coupled SPH and Particle Level Set Fluid Simulation" (Losasso et al. 2008)
Currently the target pressure is specified directly, but it will be
a lot more convenient to define this in terms of a geometric value such
as "number of hairs per area" (combined with hair "thickness").

This is a bit more awkward for artists to use, but necessary for
a stable solution of the hair continuum calculation. The grid size is
defined by the user, the extent of the grid is then calculated based on
the hair geometry. A hard upper limit prevents bad memory allocation
in case too small values are entered.

more intuitive.
Also removed a couple of unused or useless features from the UI:
* collider friction is unused and replaced in favor of true collision
* spring damping refers to structural springs (stretch), which is
not noticable in hair due to extreme stiffness atm.
* pressure factors are not sure since this feature is too unstable atm.

shape instead of a brush tool.
The brush cutting tool for hair, while useful, is not very accurate and
often requires rotating the model constantly to get the right trimming
on every side. This makes adjustments to a hair shape a very tedious
process.
On the other hand, making proxy meshes for hair shapes is a common
workflow. The new operator allows using such rough meshes as boundaries
for hair. All hairs that are outside the shape mesh are removed, while
those cutting it at some length are shortened accordingly.
The operator can be accessed in the particle edit mode toolbar via the
"Shape Cut" button. The "Shape Object" must be set first and stays
selected as a tool setting for repeatedly applying the shape.

Without this the particle system only shows the actual non-simulated
hairs ("guide hairs") during edit mode. These hairs are used for goals
as well, so showing them in the regular viewport is pretty important.
Also the usual hair curves are interpolated along the entire length,
which makes it very difficult to see exact vertex positions, unless
using exact powers of 2 for the segment number and match the display
steps.

The bend damping factor was hardcoded to the same value as the stiffness.
Now it has its own factor in the settings and button in hair dynamics.

This returns a general status (success/no-convergence/other) along with
basic statistics (min/max/average) for the error value and the number
of iterations. It allows some general estimation of the simulation
quality and detection of critical settings that could become a problem.
Better visualization and extended feedback can follow later.

incorrect.
The voxel grid needs better tool support to make it usable, so fixing
the filtering is not high priority right now.
|
|
This is part of the original method from "Volumetric Methods for
Simulation and Rendering of Hair". The current filter is a simple box
filter. Other energy-preserving filters such as gaussian filtering
can be implemented later.
The filter size is currently given as a cell count. This is not ideal,
rather it should use a geometrical length value, but this is too
abstract for proper artistical use. Eventually defining the whole grid
in terms of spatial size might work better (possibly using an external
object).

as forces, velocities, contact points etc.
This uses a hash table to store debug elements (dots, lines, vectors at
this point). The hash table allows continuous display of elements that
are generated only in certain time steps, e.g. contact points, while
avoiding massive memory allocation. In any case, this system is really
a development feature, but very helpful in finding issues with the
internal solver data.

on itself.
This uses the same voxel structure as the hair smoothing algorithm.
A slightly different method was suggested in the original paper
(Volumetric Methods for Simulation and Rendering of Hair), but this is
based on directing hair based on a target density, which is another
way of implementing global goals. Our own approach is to define a
pressure threshold above which the hair is repelled in the density
gradient direction to simulate internal pressure from collisions.
