The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.

This was removed by error during the last refactor of modiifers.
|
|
This patch implements the list panel system D7490 for grease pencil
modifiers. It also moves their drawing to a callback in
GpencilModifierTypeInfo in line with the extensible architecture
refactoring goal T75724.
This also adds the "set_error" function for grease pencil modifiers,
which hadn't been copied from mesh modifiers yet.
The implementation is basically exactly the same as for the modifier
patch (9b099c86123fc82).
Thanks to Matias Mendiola (mendio) for providing mockups for many
of the layout changes.

If the stroke is totally straight, the normal was not calculated properly.
|
|
|
|
Before, the material name was used to filter the effect of the stroke, but after the last changes in the ID code, now it's not working.
After talking with @severin, we agreed to replace the material name with a pointer. Also, this fix a design issue when the materials were linked.

This change is to align names with changes in T76498

BKE_gpencil_geom.h
This split prepare the code for future geometry functions.

The versioning was setting the factor for all modes without checking flags.
Also cleanup some unused code.

This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes.
Also, a huge code cleanup has been done at all levels.
Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.

Before, the modifiers were evaluated in Draw Engine and this required to calculate a factor to increase the VBO size.
Now, the modifiers are evaluated in Depsgraph and the Draw Engine receives the evaluated stroke with the final number of vertices. As the number of vertices is the final value already, if Draw Manager increases the number with the modifiers only increases the memory with empty space because never would be used. This commit removes this double calculation, reducing the memory usage and removes a loop to calculate the size by modifier too.
Also, the function getDuplicationFactor() has been removed because is not required anymore.

This commit adds a new filter by material using the name and not only the index.

This commit adds the frame to deformStroke Callback as a preparation for new modifiers that will need this variable.
Actually, the existing modifiers are not using the frame.

There were several problems in the old random calculation:
* Different result in the viewport and render.
* Noise "pop" in some frames.
* Random number was calculated every time the file was opened, so get different results.
Now, instead to calculate the random numbers when n number of frames changed, the random values are calculated using a unique seed by stroke.
Also, a new Seed parameter has been added and this adds more control in the noise generated. This value can be animated and get more variations.

The value of the step was calculated using a variable that was removed when the render frame change.
Now, the step is calculated using the modulus of the current frame and recalculate noise only if the remainder that results from performing integer division is equal to 0.
To calculate current frame, the first used frame is calculated to adjust real frame range.
This approach is more stable in viewport and render.

Apply clang format as proposed in T53211.

As the random seed was calculated in the copy data, the render could be a little different. Now, the data is saved in the original data.

BLI should always comes first, before DNA, BKE etc. And
`BLI_utildefines.h` should come before any other BLI (since it's some
sort of system include really, among other things...).
Thisi should help to reduce the noise in patches when adding stuff
like uint64_t members to DNA structs... ;)

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.

The first point was moving inverted because first vector was inverted. Now, the vector is changed for the first point to get the same direction.

points
Also fixed Lattice and Noise modifier.

|
|
The weight was used only for position.
|

The first point index was wrong calculated.

This is part of T57829.
Reduce the number of batches used to only one by shader type. This reduces GPU overhead and increase a lot the FPS. As the number of batches is small, the time to allocate and free memory was reduced in 90% or more.
Also the code has been simplified and all batch management has been removed because this is not necessary. Now, all shading groups are created after all vertex buffer data for all strokes has been created using DRW_shgroup_call_range_add().
All batch cache data has been moved to the Object runtime struct and not as before where some parts (derived data) were saved inside GPD datablock.
For particles, now the code is faster and cleaner and gets better FPS.
Thanks to Clément Foucault for his help and advices to improve speed.

Now the modifier can be filtered using the new layer index.
Also changed panels to put layers and passes filter always at the end of the panel.
|
|
This modifier allows to offset the keyframe animated to get more variations in the animation when reuse the same datablock.

Name hinted 'vertex index', where it's the index of the vertex group.

- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

https://code.blender.org/2018/07/grease-pencil-status-update/
This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
