Apply clang format as proposed in T53211.

No functional change, this adds LIB definition and args to cmake files.
Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS'
since there are many platforms/configurations that could break when
changing linking order.
Manually add and enable WITHOUT_SORTED_LIBS to try building
without sorted libs (currently fails since all variables are empty).
This check will eventually be removed.
See T46725.

but in general, the current grid resampling approach still seems wrong... needs more thinking
|
|
the grids should not have offsets any more, they are being transformed and resampled.
but does not look overly great yet... and is very slow, too.
|
|
invalid can mean the grid is empty or the grid class is not "LevelSet",
happens usually when the volume is empty
|
|
useful when transforming the disabled operand for example

Dilate and erode filters are now working

I also refactored the voxel remesher code to use the new API.
|
|
this merges my patch now officially to the sculpt-mode-features branch :)
|
|
This introduces a new workflow for sculpting. The voxel remesher works
with Dyntopo disabled. The user needs to run it manually once he/she
considers that the topology is too stretched to continue sculpting
normally. OpenVDB evaluates the mesh volume as a level set with a given
voxel size and it always outputs an all quads manifold mesh. It
automatically solves self-intersections and geometry errors produced by
booleans, which Dyntopo can't solve right now. Once the new mesh is
calculated, the user can continue sculpting without the overhead of
having Dyntopo enabled.
It still needs a proper UI and it has some issues. Undo is not working
on a remeshed object.

Following removal from C source code.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Better fix for T54457. It seems Debian compiles OpenVDB without ABI 3
compatibility, while Arch does enable it as is the default in the OpeVDB
CMake build system.
So now there's an option that the distribution can set depending on how
they compile their OpenVDB package.

Solution provided by Sven-Hendrik Haase.

This is used to determine which voxels are to be considered empty space.
Previously it was hardcoded for converting dense grids to OpenVDB grids
to reduce disk space usage.
This value is also useful for rendering engines to know, i.e. to
optimize ray marching.
|
|
Some other software cannot handle grid names with spaces in them. We still check for names with spaces so as to not break old
files.
This fixes T53802.

One crucial thing here: OpenVDB shoudl be compiled WITHOUT
OPENVDB_ENABLE_3_ABI_COMPATIBLE flag. This is how OpenVDB's Makefile is
configured and it's not really possible to detect this for a compiled library.
If we ever want to support that option, we need to add extra CMake argument and
use old version 3 API everywhere.

Issue was that before writing to disk grids are clipped against the
density field's tree to optimize for memory/disk space, which in the
case of simulations with no density field results in all grids having
empty trees.
For now avoid clipping against empty grids, but perhaps in the future it
can be interresting to have some UI parameters to let the user choose
the grid used for clipping.

simulations.
This commits implements OpenVDB as an extra cache format in the Point
Cache system for smoke simulations. Compilation with the library is
turned off by default for now, and shall be enabled when the library is
present.
A documentation of its doings is available here: http://
wiki.blender.org/index.php/User:Kevindietrich/OpenVDBSmokeExport.
A guide to compile OpenVDB can be found here (Linux): http://
