Add 'ID_ACTION' context to some animation curve interpolation enums.
Related to T95506/T43295.

This is needed since 4d0f846b936c9101ecb76a6db962aac2d74a460a
however change in the operator instead of the event handler is correct,
as accepting a press event should suppress drag events unless
the pass-through flag is set.
This is how select & tweak already works.
|
|
|
|
Also remove event print left in by accident.
|
|
Supporting two kinds of dragging is redundant, remove tweak events as
they only supported 3 mouse buttons and added complexity from using the
'value' to store directions.
Support only click-drag events (KM_CLICK_DRAG) which can be used with
any keyboard or mouse button.
Details:
- A "direction" member has been added to keymap items and events which
can be used when the event value is set to KM_CLICK_DRAG.
- Keymap items are version patched.
- Loading older key-maps are also updated.
- Currently the key-maps stored in ./release/scripts/presets/keyconfig/
still reference tweak events & need updating. For now they are updated
on load.
Note that in general this wont impact add-ons as modal operators don't
receive tweak events.

Use a flag for events to avoid adding struct members every time a new
kind of tag is needed - so events remain small.
This also simplifies copying settings as flags can be copied at once
with a mask.

- Rename ED_view3d_win_to_delta `mval` argument to `xy_delta` as it
as it was misleading since this is an screen-space offset not a region
relative cursor position (typical use of the name `mval`).
Also rename the variable passed to this function which also used the
term `mval` in many places.
- Re-order the output argument of ED_view3d_win_to_delta last.
use an r_ prefix for return arguments.
- Document how the `zfac` argument is intended to be used.
- Split ED_view3d_calc_zfac into two functions as the `r_flip` argument
was only used in some special cases.

Using flags makes checking multiple modifiers at once more convenient
and avoids macros/functions such as IS_EVENT_MOD & WM_event_modifier_flag
which have been removed. It also simplifies checking if modifier keys
have changed.

When X-ray mode is active the selection is done using the mesh data to
select what is closest to the cursor. When GPU subdivision is active with
the "show on cage" modifier option, this fails as the mesh used for selection
is the unsubdivided one.
This creates a subdivision wrapper before running the selection routines to
ensure that subdivision is available on the CPU side as well.

This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

This adds initial support for edit mode for the experimental new curves
object. For now we can only toggle in and out of the mode, no real
interraction is possible.
This patch also adds empty menus in edit mode. Those were added mainly
to quiet warnings as the menus are programmatically added to the edit
mode based on the object type and context.

Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

`op` --> `op->customdata`
|
|
Setting the `op->customdata` out of `viewops_data_create` makes the usage of the function clearer thus making the code easier to read.
|
|
`viewops_data_alloc` allocates and stores some pointers in
`ViewOpsData` while `viewops_data_create` reuses already stored
pointers and also stores others in `ViewOpsData`.
The similar names and usages can confuse and in this case it also
creates a dependency on the order in which these functions are called.
Merging these functions simplifies usage and deduplicates code.

Some navigation operators check flags like `RV3D_LOCK_ROTATION` in the
invoke function to see if the operation can be performed.
As the comment indicates, these checks should be in the poll function.
This avoids redundant initialization.
Note that this brings functional changes as now operators with context
`EXEC_DEFAULT` will also be affected by the flag.
(There doesn't seem to be a problem with the current code).

This fixes the crash by removing the `do_view3d_header_buttons` handler.
The code can work at a higher level here, using the operator for setting
the select mode, which makes this patch a cleanup as well.

GPU_select originally used GL_SELECT which defined the format for
storing the selection result.
Now this is no longer the case, define our own struct - making the code
easier to follow:
- Avoid having to deal with arrays in both `uint*` and `uint(*)[4]`
multiplying offsets by 4 in some cases & not others.
- No magic numbers for the offsets of depth & selection-ID.
- No need to allocate unused members to match GL_SELECT
(halving the buffer size).

During sprite fright loading of complex scenes would spend a long time in remapping ID's
The remapping process is done on a per ID instance that resulted in a very time consuming
process that goes over every possible ID reference to find out if it needs to be updated.
If there are N of references to ID blocks and there are M ID blocks that needed to be remapped
it would take N*M checks. These checks are scattered around the place and memory.
Each reference would only be updated at most once, but most of the time no update is needed at all.
Idea: By grouping the changes together will reduce the number of checks resulting in improved performance.
This would only require N checks. Additional benefits is improved data locality as data is only loaded once
in the L2 cache.
It has be implemented for the resyncing process and UI editors.
On an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz 16Gig the resyncing process went
from 170 seconds to 145 seconds (during hotspot recording).
After this patch has been applied we could add similar approach
to references (references between data blocks) and functionality (tagged deletion).
In my understanding this could reduce the resyncing process to less than a second.
Opening the village production file between 10 and 20 seconds.

This adds vertex creasing support for OpenSubDiv for modeling, rendering,
Alembic and USD I/O.
For modeling, vertex creasing follows the edge creasing implementation with an
operator accessible through the Vertex menu in Edit Mode, and some parameter in
the properties panel. The option in the Subsurf and Multires to use edge
creasing also affects vertex creasing.
The vertex crease data is stored as a CustomData layer, unlike edge creases
which for now are stored in `MEdge`, but will in the future also be moved to
a `CustomData` layer. See comments for details on the difference in behavior
for the `CD_CREASE` layer between egdes and vertices.
For Cycles this adds sockets on the Mesh node to hold data about which vertices
are creased (one socket for the indices, one for the weigths).
Viewport rendering of vertex creasing reuses the same color scheme as for edges
and creased vertices are drawn bigger than uncreased vertices.
For Alembic and USD, vertex crease support follows the edge crease
implementation, they are always read, but only exported if a `Subsurf` modifier
is present on the Mesh.

As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

This evaluator is used in order to evaluate subdivision at render time, allowing for
faster renders of meshes with a subdivision surface modifier placed at the last
position in the modifier list.
When evaluating the subsurf modifier, we detect whether we can delegate evaluation
to the draw code. If so, the subdivision is first evaluated on the GPU using our own
custom evaluator (only the coarse data needs to be initially sent to the GPU), then,
buffers for the final `MeshBufferCache` are filled on the GPU using a set of
compute shaders. However, some buffers are still filled on the CPU side, if doing so
on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose
logic is hardly GPU compatible).
This is done at the mesh buffer extraction level so that the result can be readily used
in the various OpenGL engines, without having to write custom geometry or tesselation
shaders.
We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in
order to control the data layout, and interpolation. For example, we store vertex colors
as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float
types.
In order to still access the modified geometry on the CPU side, for use in modifiers
or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`.
Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will
create such a wrapper if possible. If the final subdivision surface is not needed on
the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used.
Enabling or disabling GPU subdivision can be done through the user preferences (under
Viewport -> Subdivision).
See patch description for benchmarks.
