When the result isn't used, prefer post increment/decrement
(already used nearly everywhere in Blender).

The check was for the whole object instead of individual particle system.

This reverts commit 36faf739a71624b6ca10cec7233779f9eeace0bd.
Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.
Since this change was not sufficient to get original report fixed
is easier to simply revert for now.
Fixes T65842: Hair disappears when clicking on particle system name

- was using wrong offset [index instead of index * 4]
- also minor correction to variable naming

Allows it to be preserved during copy-on-write update when on-geometry
related update is needed.
This is a required part for T63537, where we need to preserve the entire
evaluation data when object is tagged for only RECALC_COPY_ON_WRITE.

This type of indices is not natively supported on modern GPU and
gives warning on some implementation. The memory savings it
provides is also quite minimal and unlikely to be visible on
nowadays hardware.
This remove some uneeded struct members and makes primitive
restart always enabled by default. This can be broken by addons
if they are not careful enough but many other states have this
problem.
Also leverage GL_PRIMITIVE_RESTART_FIXED_INDEX if
ARB_ES3_compatibility is supported. This removes all API calls
to change restart index depending on indices length.

The crash is related to the format, but the real reason is unknown.

Apply clang format as proposed in T53211.

This was making Autumn being half naked.

Gives 2 more bits to the segment count. Also subtract 1 because segment
count cannot be negative.

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Also rename GPUVertexAttribs to GPUVertAttrLayers,
avoids confusion with GPUVertAttr which isn't closely related.

this was working for object/collection display/render but lattice was
not taken into account for non object/collection display/render types
(halo, axis, cross, circle, ...)

Fixes T57931 Particle weight edit mode is not supported.
There is a bug that prevent refresh of the toolsettings on which is based
the weight / non-weight display selection (see T58086).

Implement strand selection visualisation but without any shading.
I think this is not the overlay job to draw the strands shaded.
We can already view the children strands shaded for now but we might add
an option to draw the shaded strand instead of (or in addition to) the
guide strand.

The idea is to only use pointers to particles in original object when
creating an edit structure. The derived mesh we get from evaluated
object.
The rest of the commit is just keeping pointers in sync.
|

|
|
This allows to rely on brush to update children positions,
and avoid tag of object. Makes it way faster to comb with
children enabled.

|
... it's getting late here.

Maybe disabled modifier check should be done higher in the call hierarchy.
|
|
Also use 'uint'.

This new system use transform feedback to compute subdivided hair points
position. For now no smoothing is done between input points.
This new system decouple the strands data (uv, mcol) with the points
position, requiring less update work if only simulation is running.
In the future, we can have compute shader do the work of the feedback
transform pass since it's really what it's meant to. Also we could generate
the child particles during this pass, releasing some CPU time.
draw_hair.c has been created to handle all of the Shading group creations
as well as subdivision shaders.
We store one final batch per settings combination because multiple viewport
or render could use the same particle system with a different subdivision
count or hair shape type.

There are a few places where DerivedMesh is still used, most notably
when calling the (not yet ported) cloth simulation. There is also still
the use of Object.derivedDeform and Object.derivedFinal. Those places are
marked with a TODO.
Some functions in the editors module were copied to accept Mesh. Those
already had 'mesh' in the name; the copies are suffixed with '__real_mesh'
for easy renaming later when the DM-based functionality is removed.
|
|
Passing the wrong index caused the particles to stop being shown when the
first particle dies.
|
|
|
|
The idea is to allow "regular" strands to update edit cache and hence
get the final update strands.
|
|
Currently unused, but is required for an upcoming work.
|
|
Makes it possible to have children strands to be visible during combing.
Actual implementation still needs work though.
|
|
|
|
We can not rely on edit->psys, it is not set for particle edit,
and there is some logic deeper inside which does different things
dependent on that.
We need to replace those checks with some some HAIR vs. PARTICLES
flag and always set psys pointer.
