2020-10-09Volumes: lower minimal voxel size in Mesh to Volume modifierJacques Lucke
The 0.1 limit was too large. The issue with making it smaller is that one can easily crash blender by making it to small. To counteract this, the step has been reduced as well. A voxel size/amount of 0 disables the modifier.
2020-10-07Refactor `BKE_id_copy_ex` to return the new ID pointer.Bastien Montagne
Note that possibility to pass the new ID pointer as parameter was kept, as this is needed for some rather specific cases (like in depsgraph/COW, when copying into already allocated memory). Part of T71219.
2020-10-07Volumes: new Volume Displace modifierJacques Lucke
This modifier uses a 3D texture to displace a volume. For now, this can only use the previously existing texture system, because we do not have a better alternative yet. Still, the results can be quite good and interesting. See D9075 for some examples. Reviewers: brecht, simonthommes Differential Revision: https://developer.blender.org/D9075
2020-10-05Fix T80897: Complex solidify crash when special ngons are mergedHenrik Dick
This has serious performance implications as the additional check makes it O(N^2) when there are a lot of merged vertices. The goal is to move the merging to the weld modifier where it would be much easier to optimize. Ref D8946
2020-10-05Fix T80893: Complex solidify special case with singularityHenrik Dick
Ref D8929
2020-10-05Fix T80895: Complex solidify compare edges by contentHenrik Dick
Even if the index of the edge is not equal the content can be equal if it has been merged. So compare the content. Ref D8931
2020-10-05Modifiers: Use vertex group options for complex solidify flat facesHenrik Dick
Ref D8945
2020-10-05Fix T80269: Match material offset in solidify modesHenrik Dick
This commit to complex solidify swaps the side of the geometry which is affected by the material offset when the normal flip option is enabled. This matches simple solidify and is considered correct/useful. Ref D8948
2020-10-05Revert "Volumes: make Mesh to Volume modifier independent of object transforms"Brecht Van Lommel
This reverts commit 66cd82a8d. This was based on a misunderstanding. We do want to take into account transforms similar to other modifiers like booleans, to support taking into account animated transforms, combining multiple meshes into one volume, etc.
2020-10-03Cleanup: Remove/replace C standard library assert() and header usagesJulian Eisel
We have our own assert implementation, `BLI_assert()` that is prefered over the C standard library one. Its output is more consistent across compilers and makes termination on assert failure optional (through `WITH_ASSERT_ABORT`). In many places we'd include the C library header without ever accessing it.
2020-10-02Volumes: make Mesh to Volume modifier independent of object transformsJacques Lucke
2020-10-01Cleanup: Use DNA defaults for cloth modifierHans Goudey
Followup for rB8398050695 This requires moving a few enum definitions to DNA instead of BKE, and adding default definitions for the two structs the cloth modifier where the cloth modifier stores its settings. The defaults are also reordered to be consistent with the order of each item in the struct.
2020-10-01remove foreachObjectLink callbackJacques Lucke
This removes `foreachObjectLink` from `ModifierTypeInfo`, `GpencilModifierTypeInfo` and `ShaderFxTypeInfo`. There is no need to have both, `foreachObjectLink` and `foreachIDLink`. There is not code that actually depends on `foreachObjectLink`. Reviewers: brecht Differential Revision: https://developer.blender.org/D9078
2020-10-01Fix subdivision surface wrong for non-limit surface and subdivision level 1Brecht Van Lommel
Remove the workaround for T59395 that increases the minimal refinement to 2 to work around an OpenSubdiv bug. This bug appears to be fixed in the latest OpenSubdiv version we are using. Problem found by Piotr Ostrowski. Ref D9076
2020-10-01Use DNA defaults system for modifiersHans Goudey
As noted in T80164, there are quite a few area of Blender where the "Reset to Default Value" operator in button context menus doesn't work. Modifiers are one of them, because the DNA defaults system was never set up for them. Additionally, this should make modifier versioning easier. Whenever a new field is added it should be automatically initialized to the default value. I had to make some ordering changes in the following modifiers to work around an error with `-Wsign-conversion` in the macros: - Solidify Modifier - Corrective Smooth Modifier - Screw Modifier Some modifiers are special cases and are skipped in this commit: - Data Transfer Modifier - Cloth Modifier - Fluid Modifier - Softbody Modifier Differential Revision: https://developer.blender.org/D8747
2020-10-01Cleanup: Remove unused variableHans Goudey
2020-10-01Fix: Mesh to Volume modifier crashes when object is in edit modeJacques Lucke
Bug and fix has been found by dfelinto, thanks.
2020-10-01Fix some inactive modifier properties not being editableBrecht Van Lommel
The convention is to keep inactive settings editable even if they are grayed out for having no effect due to other settings.
2020-09-30Subdivision Surfaces: add boundary smooth option to modifiersPiotr Ostrowski
This adds the option to either smooth the entire boundary, or to keep corners sharp, for the Subdivision Surface and Multiresolution modifiers. This mainly helps with compatibility with other software. The default behavior remains to smooth the entire boundary. Differential Revision: https://developer.blender.org/D8485
2020-09-30Subdivision Surfaces: add option disable using the limit surfacePiotr Ostrowski
This makes subdivision surfaces compatible with the old subdivision surface modifier and other applications that do not use the limit surface. This option is available on the Subdivision Surface modifier. Differential Revision: https://developer.blender.org/D8413
2020-09-30Cleanup: convert gforge task ID's to phabricator formatValentin
Cleanup old tracker task format to the new. e.g: [#34039] to T34039 Ref D8718
2020-09-30Cleanup: use 'use_' prefix for RNA booleansCampbell Barton
Some of the naming was quite misleading.
2020-09-30Cleanup: sort struct declarationsCampbell Barton
2020-09-29Fix T71981: Alembic vertex interpolation can jumble meshSybren A. Stüvel
Add an option to disable Alembic vertex interpolation. Bump subversion from 5 to 6. Alembic stores mesh samples at specific time keys; when a frame in Blender maps to a timecode between two samples, Blender will interpolate the mesh vertex positions. This interpolation only happens when the mesh has a constant topology, but sometimes this was not detected properly when the vertices change order, but the number of mesh elements remains the same. This would result in a mesh with jumbled up vertices (T71981). With this patch, users have the ability to disable vertex interpolation. An alternative would be to have better detection of topology changes, but that that'll cause a considerable slowdown. Maniphest Tasks: T71981 Differential Revision: https://developer.blender.org/D9041
2020-09-29Volumes: new Mesh to Volume modifierJacques Lucke
This modifier can only be added to Volume objects. It takes a mesh as input and generates a "density" grid near the surface or in the enclosed volume. Ref T73201. Reviewers: brecht Differential Revision: https://developer.blender.org/D9032
2020-09-25Fix Tests for Weld Modifier with KD-TreeHenrik Dick
Fixes the failing tests and reintroduces the KD-Tree solution. Reviewed By: mano-wii Differential Revision: https://developer.blender.org/D9013

2020-09-25Weld Modifier: Disable the KD Tree solutionGermano Cavalcante
This solution is causing the modifier regression test to fail. Also fix a mistake to allocate `vert_dest_map` twice.
2020-09-25Modifiers: add StructRNA pointer field to ModifierTypeInfoJacques Lucke
This reduces the number of places that have to be modified when a new modifier is added. Reviewers: campbellbarton Differential Revision: https://developer.blender.org/D9000
2020-09-25Modifiers: add icon field to ModifierTypeInfoJacques Lucke

2020-09-24Fix (unreported) memory leak in Extrude mode of the Solidify modifier.Bastien Montagne
2020-09-24Weld Modifier: Use KD Tree in detecting the geometry to be weldedHenrik Dick
This commit replaces the BVH Tree currently used by the Weld Modifier with the KD Tree used by `Merge > By Distance`. This changes the result of the Weld Modifier to more closely match `Merge > By Distance`. There is also a big performance advantage. Here is an overview (models in D8995): | 2.90 (Duplicate Limit = 0) | 2.90 (Duplicate Limit = 1) | master (BVH) (Duplicate Limit = 1) | patch (KD) | | 1.69s| 0.17s | 0.12s | 0.029s | Differential Revision: https://developer.blender.org/D8995
2020-09-24Fix: add radius attribute in simulation modifierJacques Lucke
This is necessary to not make it crash immediatly after recent changes.
2020-09-22Fix T80996: Weight Proximity modifier: crash going to editmode on aPhilipp Oeser
target in certain situations Regression from rBdeaff945d0b96. mesh_ensure_looptri_data would overflow. Crash would only happen if a Data Transfer modifier (transferring UVs) follows, so exact reason for this is not yet entirely clear. Also there are edit-mode versions of the following BVH lookup functions so it could be avoided (since this is a expensive operation), marking as TODO. Similar fix as - rB0945a79ed1eafae444d3021a5912cb39801a7209 - rB56d7e39b92997768b3db8ce2dbc262f869994145 Reviewers: mont29, campbellbarton Maniphest Tasks: T80996 Differential Revision: https://developer.blender.org/D8973
2020-09-21Weld Modifier: Performance improvementHenrik Dick
This commit contains the Performance improvement, that was originally proposed in D8966. It improves the performance of the Weld Modifier by a lot. It had a loop with execution time O(N^2) which is now O(N*log(N)) at a bare maximum.
2020-09-20Sanitize type 'size' parameters in our read/write file codeBastien Montagne
This patch tries to sanitize the types of our size parameters across our read and write code, which is currently fairly inconsistent (using `int`, `uint`, `size_t`...), by using `size_t` everywhere. Since in Blender file themselves we can only store chunk of size `MAX_INT`, added some asserts to ensure that as well. See {T79561} for details. Differential Revision: https://developer.blender.org/D8672
2020-09-20Fix invert vertex group weight miscalculation for modifiersCody Winchester
Warp & weight vertex-group editing modifiers miscalculated vertex weight inversion, the weights were multiplied before being subtracted from 1. Ref D8241
2020-09-13Apply patch D8816, from Zachary(AFWS) for collection boolean operand.Howard Trickey
Also added code so that exact solver does the whole collection at once. This patch allows users to use a collection (as an alternative to Object) for the boolean modifier operand, and therefore get rid of a long modifier stack.

2020-09-07Decimate Modifier: Restore vertex group factor property in UIHans Goudey
This property was inadvertently removed from the modifier's panel and it wasn't caught in time for the release of 2.90. Thanks to the user "VermossomreV" for bringing this to my attention. Differential Revision: https://developer.blender.org/D8790
2020-09-07Add a Self option to the Exact boolean modifier. Fixes T52425.Howard Trickey
With this option, self-intersections in either or both operands will be handled properly (if both sides are piecewise winding number constant, and maybe some other cases too). In the Boolean tool, this flag was there already but the code forced a unary operation in that case; this commit corrects it to make a binary operation. This flag makes the code slower, which is why it is an option and not an always-on thing.
2020-09-07Fix T77763: Wrong highlight of active grab vertexSergey Sharybin
The "Grab Active Vertex" in sculpt mode highlights the vertex and the neighbor vertices. This was working wrong in the case when mesh has multires modifier at sculpt level 0 and has shape keys. The issue was caused by the wrong crazy space calculation, which was ignoring subdivision level. This is an oversight from the initial implementation: the modifier has no effect if the subdivision level is 0.
2020-09-07Multires: Fix memory leak when multires is at level 0Sergey Sharybin
There is no SubdivCCG created in this case, meaning ownership of the Subdiv was not altered.

2020-09-03Modifiers: default to exact boolean method ignoring build optionsCampbell Barton
This change doesn't impact release builds, in general avoid having defaults depend on build options since it means files from different builds won't match.
