I think this example does not belong into the api docs and certainly not in the place where it was until now.
Maybe this can become a template in Blender but personally I don't see much value in it as an "official example" because it is hard to see what is going on exactly.
There are a few other examples that show how to use the GPUOffScreen object now.

Technically this is only the view matrix, not model view matrix.
And view layer was missing from the pydoc.
|
|
- Was setting active state, making it necessary to backup/restore
active object in cases where this isn't needed.
Existing scripts are explicitly setting the active object when needed.
- Use a boolean select arg (toggle selection wasn't used anywhere).
- Add an optional view layer argument since scripts should be able to
operate outside the user context.

RNA's ViewLayer would present 'first level' of layer collection as a
list (collection property), when it is actually now only a single item,
same as the scene's master collection.
Note: did not try to update view_layer python tests, those are already
fully broken for quiet some time I guess (they still assume
view_layer.collections to be mutable e.g.)...

Was still 2.7x code... ;)

Strange that the `bpy.utils.register_class` utility does not remove the reference of the class with same name.

The image I get is a bit too dark, which is the same I get in the viewport
itself when there is no Display Device. So I believe for cases like this
we need to have color management on top of the buffer.
Also, on EEVEE it looks like it needs to clear some extra buffers. You can see
that, by rotating the camera view around.
That said, this is the first step to bring back fun addons
that use external offscreen buffers.
Note: When using gpu offscreen with POST_VIEW (as oppose to POST_PIXEL)
I get a crash with DST having 0xFF..

Maybe it's still early to set the new drawing api for python.
But joining these two modules is an initial step.
```
>>> gpu.
matrix
select
types
```
```
>>> gpu.types.GPU
Batch(
OffScreen(
VertBuf(
VertFormat(
```
The creation of a new offscreen object is now done by the `GPUOffscreen.__new__` method.

OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

Folders removed entirely:
* //extern/recastnavigation
* //intern/decklink
* //intern/moto
* //source/blender/editors/space_logic
* //source/blenderplayer
* //source/gameengine
This includes DNA data and any reference to the BGE code in Blender itself.
We are bumping the subversion.
Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.

With changes from Campbell Barton as well.
|
|
- Undo that changes modes currently asserts,
since undo is now screen data.
Most likely we will change how object mode and workspaces work
since it's not practical/maintainable at the moment.
- Removed view_layer from particle settings
(wasn't needed and complicated undo).

https://docs.blender.org/manual/en/dev/game_engine/python_api/videotexture.html
Had a few things that this file did not while this file having things the other did not.
To fix, I merged both documents into the python api.
|
|
|
|
- The common name in computer science are 'getters' and 'setters', so by
adding these names to the documentation (while 'get' and 'set are still
also mentioned) we improve findability. Having 'Getters/Setters' as a
title also makes it clearer that this example is not just about
getting or setting the property value.
- Added a little prefix to each printed value, so that print statement,
expected output, and real output can be matched easier.
|
|
The old example had two downsides:
- It promoted a blocking UI design, where the user is shown a popup
before actually executing the operator.
- It didn't show how to actually use the property values.
The new code avoids these mistakes. The properties are also shown in the
redo panel in the 3D view.
Note that I also changed the bl_idname, as this is an example about
properties, not about dialogue boxes, and changed the class name to use
the standard operator naming convention.
I also extended the example to include a panel that sets multiple
properties of the operator, since I see questions about this relatively
frequently.

Initial support for Python/Manipulator integration
from 'custom-manipulators' branch.
Supports:
- Registering custom manipulators & manipulator-groups.
- Modifying RNA properties, custom values via get/set callbacks,
or invoking an operator.
- Drawing shape presets for Python defined manipulators (arrow, circle, face-maps)
Limitations:
- Only float properties supported.
- Drawing only supported via shape presets.
(we'll likely want a way to define custom geometry or draw directly).
- When to refresh, recalculate manipulators will likely need
integration with notifier system.
Development will be continued in the 2.8 branch
