This commit adds a node that fills every element of an attribute
with the same value. Currently it supports float, vector, and color
attributes. An immediate use case is for "billboard" scattering.
Currently people are using the same input to a Random Attribute node's
min and max input to fill every element of a vector with the same value,
which is an unintuitive way to accomplish the same thing.

Since the initial merge of the geometry nodes project, the modifyPointCloud
function already was already modifying a geometry set. The function wasn't
renamed back then, because then the merge would have touched many
more files.

Caused by rB4212b6528af.
outlineColor is computed by the vertex shader, so not a uniform.
So outlineColor was undefined.
note: it was still possible to run into the situation that a selected UV
is drawn ontop of a selected pinned UV [you had to disable sticky
selection for this], now also make sure selected-pinned are drawn
topmost, then selected, then unselected UVs.

Previously, the transformation of recursive instances did not work as
on would expect. Second-level instances would detach from first-level
instances when the object was moved.
|
|
Custom properties with characters that needed escaping
had f-curves created with invalid paths.
|
|
This was escaping the '[' character, which isn't needed for quoted text.
|
|
bl_blendfile_io & bl_blendfile_liblink shared a filename,
which could make these tests fail.

This was returning an empty allocated string, however almost
all callers checked if the return value was NULL before freeing,
making for misunderstandings on the intended use of this function.
BCAnimationSampler::initialize_curves for example detected the
f-curves animation type to 'bone' based on a non-NULL return value
which never failed.
Also fixes two leaks where the the result of BLI_str_quoted_substrN
wasn't freed.
|
|
BLI_str_quoted_substrN didn't unescape the resulting string,
yet all callers were using this with animation paths which are
created using BLI_str_escape().
- Fix BLI_str_quoted_substrN use with escaped strings by calling
BLI_str_unescape().
Note that it's possible we want an a version of this function that
keeps escape characters. This could be added if it's required.
- Fix end quote detection using BLI_str_escape_find_quote
checking for `\"` isn't reliable since an even number of back-slashes
before a quote means it's not escaped.
|
|
Duplicate logic for this exists in BLI_str_quoted_substrN,
which doesn't properly support escaping.

Use '_len' or '_line_number'.

Utility to perform the reverse of `bpy.utils.escape_identifier`
|
|
|
|
Add support for escaping \a, \b & \f for completeness,
currently it's not required.
|
|
Performs the reverse of BLI_str_escape.
This allows logic to be removed from RNA path handling.
|
|
|
|
Prepare for `BLI_str_unescape` which doesn't read well
without the separator.

The issue is caused by stale data on the Mesh Node which is not cleared
during synchronizing since the socket API refactor so that we can detect
changes. However, synchronization only updates the sockets of the Mesh,
so other properties were left with outdated values.
This caused an underflow when computing attribute size for undisplaced
coordinates as it was using the current number of vertices minus the
previous count of subdivision vertices, which at this point should be 0.
Added a simple method to clear non socket data. Also modified
Mesh.add_undisplaced to always use an ATTR_PRIM_GEOMETRY as the data is
not subdivided yet and it avoids any further issues regarding computing
attribute sizes.

Testing equality of vectors can't be done properly if they are implicitly
converted to float before-hand. This adds a lot of boilerplate code to
the node, maybe that can made more elegant in the future, but it's not
so complicated anyway.
|
|
For the attribute comparison node, it makes sense to read both input
attributes implicitly converted to the same data type. But the choice
of which of the two data types to read with is somewhat arbitrary.
This commit adds a utility function to choose the least "complex" data
type as a lowest common denominator, to make that choice less arbitrary
, and to support other needs in the future.
|
|
With the previous helper function in this file you had to know the data
type you wanted for the input attribute before requesting it. This adds
another utility function for getting the data type without building the
attribute. The attribute's can be requested later after doing some
logic to figure out the right data type to read.
No functional changes in this commit.

This adds deformation types to snake hook and the elastic deformation
type. This mode deforms the mesh using a kelvinlet instead of applying
the displacement directly inside the brush radius, which is great for
stylized shapes sketching.
Changes in rake rotation when using elastic are too strong when set
to 1, so I'll add a nicer way to support rake rotations with smoother
transitions in the future.

relation immediately
Texture and ParticleSettings have a DEG relation, but
`DEG_relations_tag_update` was not called when the texture changed.
This lead to no updates when e.g. texture size changes, relation only
went into full effect after save/reload or adding/removing keyframes.
Two places were additional relation tagging is needed:
- ParticleSettings `active_texture` changes
- ParticleSettingsTextureSlot (basically any TextureSlots') texture
changes

The change to match socket color and category was already done, but it was missing
versioning code to update the theme on load.
Fixes T83500 (already closed as invalid, but this would solve the non-matching colors)

The SVM AO node calls "scene_intersect_local" with a NULL pointer for the intersection
information, which caused a crash with OptiX since it was not checking for this case and
always dereferencing this pointer. This fixes that by checking whether any hit information
was requested first (like is done in the BVH2 intersection routines).

This is a non-functional change. The functionality introduced in this commit
is not used in master yet. It is used by nodes that are being developed in
other branches though.

Now the gizmo is drawn only when the eventstate located in
`wm->winactive->eventstate` has not changed.
So it doesn't matter if it's "selected" or not.
This commit also removes the use of the private header "wm.h"

Windows
This is a workaround for T80804.
There's a startup crash that happens on 2.91.0 on Windows, an `EXCEPTION_ACCESS_VIOLATION`
on `atio6axx.dll`. It is triggered by `glClear` on the `detect_mip_render_workaround`
function. The workaround moves the function after the device/driver workaround section and
sets the flag to the affected one to avoid running the check.
It is deprecated hardware that has not meet the minimum requirements since 2.79, but is
still usable and this extends its usability a bit before the cards are finally blacklisted.
