This adds initial multi-object editing support.
- Selected objects are used when entering edit & pose modes.
- Selection & tools work on all objects however many tools need porting
See: T54641 for remaining tasks.
Indentation will be done separately.
See patch: D3101

Blender allows this.
The Cube in the file in the report would always disappear with the non camera view.
The clip_end was too small.
The correction here is only on the assert.

And Cleanup.

Orthographic frustum was incorrect.
There was double transformation.
|
|
Although somewhat less micro efficient, I decided to separate the `viewinv` matrix to calculate the world position separately.
This makes it easier to understand the code.

This gets rid of the need of a geom shader and instancing.
Both are pretty slow compared to the new method.
The only moment the old method could be better is when scene is filled
with lots of objects and most of the objects in the shadow map appear
on every layer.
But even then, we could optimize the culling and minimize the overhead.

draw_frustum_boundbox_calc does not work properly it seems in this case.

`glFinish()` that was causing bad perf issue on `Intel(R) HD Graphics 4000`.
|
|
`Intel(R) HD Graphics 4000` driver sometimes does stupid things.

This was only used for viewport rendering, where we can just pass the engine
type directly. There is no technical reason why we can't draw the same depsgrpah
with different render engines.
It also led to some weird things like requiring a render engine for snapping
and raycast API functions.

Only recreate ogl context if we cannot reuse the one of the previous thread.
Adding lots of shaders were recreating as many ogl context which was very
slow.
|
|
This means fewer indices to store. That being said, it seems to be a little
slower because of the restart index. But that's in the case we would be
vertex bound, which is mostly never going to happen.
|
|
Before, the drawing functions sometimes froze with `AMD Radeon HD 7570M`.
|
|
Only compile hair shader if we need it.
|
|
Only compile the needed shadow shaders to reduce the startup time.
Theses shaders is taking forever to compile on intel (~5s each).
|
|
Shadows makes it more readable and are relatively cheap now.
|
|
This caused too many problems syncing object modes
with multiple objects/windows/workspaces, see: D3130 for details.

usage.
The problem was that textures were assigned to different slots on different draw
calls, which caused shader specialization/patching by the driver. So the shader
would be compiled over and over until all possible assignments were used.

frustum boundbox

Was causing black / corrupted scene because of broken downsample
Add a debug check to not run into this problem again.

The way how particle state is to be accessed or used did not change
in Blender 2.8, so the drawing code should follow old design.
This code is somewhat duplicated from drawobject.c, but old draw
code is on the way to be removed anyway.
This fixes issue with disappearing particles when tweaking number
of particles.
|
|
This way we don't have to re-initialize the full evaluation
context in every area we need it.
|
|
Allows us to easily add fields which we never want to
be initialized, but still keep sane order of fields in
the structure itself.
|
|
|
|
Do early output and reduce level of indentation.
|
|
|
|
This is also much cleaner and taking 1 drawcall instead of 2.
|

invert -> inverse

This is in order to not mix it with the incomming buffer textures.
|
|
Theses are no longer relevant. Better talk about shgroup directly.

This refactor modernise the use of framebuffers.
It also touches a lot of files so breaking down changes we have:
- GPUTexture: Allow textures to be attached to more than one GPUFrameBuffer.
This allows to create and configure more FBO without the need to attach
and detach texture at drawing time.
- GPUFrameBuffer: The wrapper starts to mimic opengl a bit closer. This
allows to configure the framebuffer inside a context other than the one
that will be rendering the framebuffer. We do the actual configuration
when binding the FBO. We also Keep track of config validity and save
drawbuffers state in the FBO. We remove the different bind/unbind
functions. These make little sense now that we have separate contexts.
- DRWFrameBuffer: We replace DRW_framebuffer functions by GPU_framebuffer
ones to avoid another layer of abstraction. We move the DRW convenience
functions to GPUFramebuffer instead and even add new ones. The MACRO
GPU_framebuffer_ensure_config is pretty much all you need to create and
config a GPUFramebuffer.
- DRWTexture: Due to the removal of DRWFrameBuffer, we needed to create
functions to create textures for thoses framebuffers. Pool textures are
now using default texture parameters for the texture type asked.
- DRWManager: Make sure no framebuffer object is bound when doing cache
filling.
- GPUViewport: Add new color_only_fb and depth_only_fb along with FB API
usage update. This let draw engines render to color/depth only target
and without the need to attach/detach textures.
- WM_window: Assert when a framebuffer is bound when changing context.
This balance the fact we are not track ogl context inside GPUFramebuffer.
- Eevee, Clay, Mode engines: Update to new API. This comes with a lot of
code simplification.
This also come with some cleanups in some engine codes.

This includes a few modification:
- The biggest one is call glActiveTexture before doing any call to
glBindTexture for rendering purpose (uniform value depends on it).
This is also better to know what's going on when rendering UI. So if
there is missing UI elements because of this commit look for this first.
This allows us to have "less calls" to glActiveTexture (I did not
measure the final count) and less checks inside GPU_texture.
- Remove use of GL_TEXTURE0 as a uniform value in a few places.
- Be more strict and use BLI_assert for bad usage of GPU_texture functions.
- Disable filtering for integer and stencil textures (not supported by
OGL specs).
- Replace bools inside GPUTexture by a bitflag supporting more options to
identify texture types.

Since we are rendering draw manager's command in a separate context, we
don't need to save/restore the UI opengl state attributes/config.
|
|
This module has no use now with the new DrawManager and DrawEngines and it
is using deprecated paths.
Moving gpu_shader_fullscreen_vert.glsl
