Basic Alembic support All in all, this patch adds an Alembic importer, an Alembic exporter, and a new CacheFile data block which, for now, wraps around an Alembic archive. This data block is made available through a new modifier ("Mesh Sequence Cache") as well as a new constraint ("Transform Cache") to somewhat properly support respectively geometric and transformation data streaming from alembic caches. A more in-depth documentation is to be found on the wiki, as well as a guide to compile alembic: https://wiki.blender.org/index.php/ User:Kevindietrich/AlembicBasicIo. Many thanks to everyone involved in this little project, and huge shout out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the custom builds and compile fixes.

UI: Drag and Drop Modifiers, Layout Updates This patch implements the list panel system D7490 for modifiers. It also moves modifier drawing to a callback in ModifierTypeInfo in line with the extensible architecture refactoring goal T75724. This adds a PanelRegister callback and utilities for registering panels and subpanels. It also adds the callbacks for expansion saving and drag and drop reordering described in D7490. These utilities, callbacks, and other common UI elements shared between modifiers live in MOD_ui_common.c. Because modifier buttons are now in panels, we can make use of subpanels for organization. The UI layouts also use the single column layout style consistently used elsewhere in Blender. Additionally, the mode-setting buttons are aligned and ordered consistently with the outliner. However, the large number of UI changes in this patch may mean that additional polishing is required in master. Thanks to William Reynish (@billreynish) who did a fair amount of the layout work and to Julian Eisel (@Severin) for consistent help. Differential Revision: https://developer.blender.org/D7498

Cycles: add support for rendering deformation motion blur from Alembic caches. This patch adds the ability to render motion blur from Alembic caches. The motion blur data is derived from a velocity attribute whose name has to be defined by the user through the MeshSequenceCache modifier, with a default value of ".velocities", which is the standard name in Alembic for the velocity property, although other software may ignore it and write velocity with their own naming convention (e.g. "v" in Houdini). Furthermore, a property was added to define how the velocity vectors are interpreted with regard to time : frame or second. "Frame" means that the velocity is already scaled by the time step and we do not need to modify it for it to look proper. "Second" means that the unit the velocity was measured in is in seconds and so has to be scaled by some time step computed here as being the time between two frames (1 / FPS, which would be typical for a simulation). This appears to be common, and is the default behavior. Another property was added to control the scale of the velocity to further modify the look of the motion blur.

Fix T71981: Alembic vertex interpolation can jumble mesh 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.

"Frame" means that the velocity is already scaled by the time step and we do not need to modify it for it to look proper. "Second" means that the unit the velocity was measured in is in seconds and so has to be scaled by some time step computed here as being the time between two frames (1 / FPS, which would be typical for a simulation). This appears to be common, and is the default behavior. Another property was added to control the scale of the velocity to further modify the look of the motion blur.

It also moves modifier drawing to a callback in ModifierTypeInfo in line with the extensible architecture refactoring goal T75724. This adds a PanelRegister callback and utilities for registering panels and subpanels. It also adds the callbacks for expansion saving and drag and drop reordering described in D7490. These utilities, callbacks, and other common UI elements shared between modifiers live in MOD_ui_common.c. Because modifier buttons are now in panels, we can make use of subpanels for organization. The UI layouts also use the single column layout style consistently used elsewhere in Blender. Additionally, the mode-setting buttons are aligned and ordered consistently with the outliner. However, the large number of UI changes in this patch may mean that additional polishing is required in master.

Fix T71981: Alembic vertex interpolation can jumble mesh 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.

uiItemR(layout, ptr, "velocity_scale", 0, NULL, ICON_NONE);
Cycles: add support for rendering deformation motion blur from Alembic caches. This patch adds the ability to render motion blur from Alembic caches. The motion blur data is derived from a velocity attribute whose name has to be defined by the user through the MeshSequenceCache modifier, with a default value of ".velocities", which is the standard name in Alembic for the velocity property, although other software may ignore it and write velocity with their own naming convention (e.g. "v" in Houdini). Furthermore, a property was added to define how the velocity vectors are interpreted with regard to time : frame or second. "Frame" means that the velocity is already scaled by the time step and we do not need to modify it for it to look proper. "Second" means that the unit the velocity was measured in is in seconds and so has to be scaled by some time step computed here as being the time between two frames (1 / FPS, which would be typical for a simulation). This appears to be common, and is the default behavior. Another property was added to control the scale of the velocity to further modify the look of the motion blur.

It also moves modifier drawing to a callback in ModifierTypeInfo in line with the extensible architecture refactoring goal T75724. This adds a PanelRegister callback and utilities for registering panels and subpanels. It also adds the callbacks for expansion saving and drag and drop reordering described in D7490. These utilities, callbacks, and other common UI elements shared between modifiers live in MOD_ui_common.c. Because modifier buttons are now in panels, we can make use of subpanels for organization. The UI layouts also use the single column layout style consistently used elsewhere in Blender. Additionally, the mode-setting buttons are aligned and ordered consistently with the outliner. However, the large number of UI changes in this patch may mean that additional polishing is required in master. Thanks to William Reynish (@billreynish) who did a fair amount of the layout work and to Julian Eisel (@Severin) for consistent help. Differential Revision: https://developer.blender.org/D7498

Objects: add infrastructure for hair, pointcloud, volume modifiers There is no user visible difference in standard builds, as there are no volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only modifiers are now available for hair and pointcloud objects. Differential Revision: https://developer.blender.org/D7141

Modifiers: New callbacks for reading and writing .blend files This is part of a greater blenloader decentralization effort (T76372). For modifiers the goal is that fewer files have to be modified when a new modifier is added. This patch just adds the `blendWrite` and `blendRead` callbacks to `ModifierTypeInfo` but does not change any other code yet. In the next steps, modifier specific code will be moved from `writefile.c` and `readfile.c` into their corresponding `MOD_*` files.

Basic Alembic support All in all, this patch adds an Alembic importer, an Alembic exporter, and a new CacheFile data block which, for now, wraps around an Alembic archive. This data block is made available through a new modifier ("Mesh Sequence Cache") as well as a new constraint ("Transform Cache") to somewhat properly support respectively geometric and transformation data streaming from alembic caches. A more in-depth documentation is to be found on the wiki, as well as a guide to compile alembic: https://wiki.blender.org/index.php/ User:Kevindietrich/AlembicBasicIo. Many thanks to everyone involved in this little project, and huge shout out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the custom builds and compile fixes.
