When this preference is enabled, use selection behavior matching the
graph editor. We may want to make this default (see T98552).
|
|
Some edit-curve operators used an 'ok' variable to represent
if the selection was found and if a change was made.
Previously it would only return cancel if an error was shown
causing a redundant undo step to be added without a selection.
Since this is simple behavior that shouldn't need much explanation,
use two variables with meaningful names to avoid confusion.
Reviewing D14511 highlighted this issue.

Remove the extended version of ED_curve_editnurb_select_pick,
pass the size threshold directly to this function but as the distance in
pixels instead of a multiplier for ED_view3d_select_dist_px.
Using a multiplier is a less direct way to reference the threshold.

This tool can be used to rapidly edit curves. The current set of
functionalities for Bezier splines are as follows:
The functionalities are divided into three versions of the operator:
* Left-Click
* Ctrl + Left-Click
* Double Click
All current functionalities and their defaults are as follows:
* Extrude Point: Add a point connected to an existing point.
Enabled for Left-Click.
* Extrude Handle Type: Type of the handles of the extruded points.
Can be either Vector or Auto. Defaults to Vector.
* Delete Point: Delete existing point.
Enabled for Ctrl + Left-Click.
* Insert Point: Insert a point into a curve segment.
Enabled for Ctrl + Left-Click.
* Move Segment: Move curve segment.
Enabled for Left-Click.
* Select Point: Select a single point or handle at a time.
Enabled for Left-Click.
* Move point: Move existing points or handles.
Enabled for Left-Click.
* Close Spline: Close spline by clicking the endpoints consecutively.
Defaults to True.
* Close Spline Method: The condition for Close Spline to activate.
Can be one of None, On Press or On Click.
Defaults to On Click for Left-Click and None for the others.
* None: Functionality is turned off.
* On Press: Activate on mouse down.
This makes it possible to move the handles by dragging immediately
after closing the spline.
* On Click: Activate on mouse release.
This makes it possible to avoid triggering the Close Spline
functionality by dragging afterward.
* Toggle Vector: Toggle handle between Vector and Auto handle types.
Enabled for Double Click on a handle.
* Cycle Handle Type: Cycle between all four handle types.
Enabled for Double Click on the middle point of a Bezier point.
The keybindings for the following functionalities can be adjusted from
the modal keymap
* Free-Align Toggle: Toggle between Free and Align handle types.
Defaults to Left Shift. Activated on hold.
* Move Adjacent Handle: Move the closer handle of the adjacent vertex.
Defaults to Left Ctrl. Activated on hold.
* Move Entire: Move the entire point by moving by grabbing on the handle
Defaults to Spacebar. Activated on hold.
* Link Handles: Mirror the movement of one handle onto the other.
Defaults to Right Ctrl. Activated on press.
* Lock Handle Angle: Move the handle along its current angle.
Defaults to Left Alt. Activated on hold.
All the above functionalities, except for Move Segment and
those that work with handles, work similarly in the case of Poly
and NURBS splines.

Currently this isn't used in the key-map, it will eventually
allow the 3D viewports tweak tool to match the behavior of other
editors that support tweaking a selection without first de-selecting
all other elements.

- Add SelectPick_Params struct to make picking logic more
straightforward and easier to extend.
- Use `eSelectOp` instead of booleans (extend, deselect, toggle)
which were used to represent 4 states (which wasn't obvious).
- Handle deselect_all when pocking instead of view3d_select_exec,
de-duplicate de-selection which was already needed in when replacing
the selection in picking functions.
- Handle outliner update & notifiers in the picking functions
instead of view3d_select_exec.
- Fix particle select deselect_all option which did nothing.

This patch enables all 8 combinations of Nurbs modes: Cyclic,
Bezier and Endpoint. Also removes restriction on Bezier Nurbs order.
The most significant changes are mode combinations bringing new
meaning. In D13891 is a scheme showing NURBS with same control
points in a modes, and also further description of each possible case.

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 commit improves NURBS knot generation by adding proper support
for the combination of the Bezier and cyclic options. In other cases
the resulting knot doesn't change. This cyclic Bezier knot is used to
create accurate accurate "Nurbs Circle", "Nurbs Cylinder" primitives.
"Nurbs Sphere" and "Nurbs Torus" primitives are also improved by
tweaking the spin operator.
The knot vector in 3rd order NURBS curve with Bezier option turned on
(without cyclic) is changed in comparison to previous calculations,
although it doesn't change the curve shape itself.
The accuracy of the of NURBS circle is fixed, which can be checked by
comparing with mesh circle. Tessellation spacing differences in
circular NURBS is also fixed, which is observable with the NURBS
cylinder and sphere primitives. These were causing seam-like effects.

worst. This patch renames them to be consistent with the terms
used to refer to the values in the UI.

- Show "Lasso Select" in menus (along with Box & Circle select)
- Show "Extrude to Cursor" (along with other extrude actions).
- Rename operators that add/extrude on Ctrl-Click

This is mainly for discoverability.

This fixes T86440
As the CU_2D flag is set for nurbs, a Curve can have 2D nurbs mixed with 3D.
But the UI does not allow this mixing. It updates all nurbs to 2D or 3D when set.
So remove this specific flag for nurbs.
This may break old files, since 2D curves with mixed 3D are now set as 3D.

NurbsPath leads crash.
Crash occurs at `assert(builder->index_len < builder->max_index_len)`.
Non-bezier nurbs were being created with abnormal values causing the
causing edge count in the draw manager to be incorrect.
This commit also deduplicates and adds descriptions to the code.
Thanks @PratikPB2123 for pointing out where the error is.

When joining curves, the resulting curve will inherit the bevel depth of
the active curve, but the radii would stay the same which leads to
changed appearance when joining.
Now compensate for this taking the different bevel depths into account
(if present).
Was a feature request here (and I also think we had reports about this
-- which were usually turned down as not-a-bug):

The Surface -> Nurbs Curve behaves now like the Curve -> Nurbs Curve,
if you initially select less than all points. So, multiple points can

This commit uses continue in loops and returning early to reduce
indentation in long functions, only where this results in a significant
improvement. Also includes a few LISTBASE_FOREACH macros.
|
|
These changes should result in more readable and undestandable code,
especially where while loops were use instead of for loops. They are
not comprehensive, and I skipped wherever the change was not obvious.

Those were only shallow wrappers around `BKE_id_copy`, barely used (even
fully unused in some cases), and we want to get rid of those ID-specific
helpers for the common ID management tasks. Also prevents weird custom
behaviors (like `BKE_object_copy`, who was the only basic ID copy
function to reset user count of the new copy to zero).

Previously, it was kind of a mess. In different places it was using `char`, `short` and `int`.
The changed properties are flags that are operated upon using bit operations. Therefore, the integer type should be unsigned. Since we only use 2 bits of these flags, `uint8_t` is large enough.
Especially note the change I had to make in `RNA_define.h` to make this work.
