Not the cleanest implementation but the simplest.
This doubles the number of default shader variations.

Implicit function declaration caused by missing include
in the recent fix.

Thanks @mano-wii for finding the fix.

Also fixes the sampling of hashed shadows.
|
|
|
|
Was caused by division not giving a fully opaque alpha value.
|
|
This was caused by 2 things: Shadow map bias and aliasing.
It made the expected depth of the shadowmap further than the surface
itself in some cases. In normal time this leads to light leaking on normal
shadow mapping but here we need to always have the shadowmap depth above
the shading point.
To fix this, we use a 5 tap inflate filter using the minimum depth of all
5 samples. Using these 5 taps, we can deduce entrance surface derivatives
and there orientation towards the light ray. We use these derivatives to
bias the depth to avoid wrong depth at depth discontinuity in the shadowmap.
This bias can lead to some shadowleaks that are less distracting than the
lightleaks it fixes.
We also add a small bias to counteract the shadowmap depth precision.

Predivide all radiance components as the alpha effect comes from the hashed
transparency (pixel rejection).

Adds a check when starting blender if your platform is supported. We use a blacklist
as drivers are updated more regular then blender (stable releases).
The mechanism detects if the support level changed or has been validated by the user previously.
Changes can happen due to users updating their drivers, but also when we change the support
level in our code base.
When the user has seen the limited support level message it is saved in the user config.
It would be better to have a system specific config section, but currently not clear
what could benefit from that.
When the platform is unsupported or has limited support a dialog box will appear including a link
to our user manual describing what to do.
**Windows**
Windows uses the MessageBox that is provided by the windows kernel.
**X11**
We use a very lowlevel messagebox for X11. It is very limited in use and can be fine tuned when needed.
**SDL/APPLE**
There is no implementation for SDL or APPLE at this moment as the platform support feature targets mostly Windows users.

Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.

Currently unused, but will allow to keep of an owner of the depsgraph.
Could also simplify other APIs in the future by avoiding to pass bmain
explicitly to relation update functions and things like that.

When the result isn't used, prefer post increment/decrement

To fix this, we just scramble the halton sequence by multiplying by a large
prime number.
It seems to work fine in practice.
We also tried Sobol sequence but it has a less uniform pattern for low
number of sample.

This change implements the basics as described in {T68312} for the
shading modes.
* LookDev shading mode is renamed to Material Preview. It always uses Eevee as renderer, and is intended to provide a fast material preview suitable for texture painting, and texture and material setup.
* Rendered shading gains "Use Scene Lights" and "Use Scene World" options similar to current Material Preview. These will be enabled by default. When Use Scene World is turned off, HDRIs will be used for lighting instead. These options are available for EEVEE and Cycles.
* Renderers will be able to customize the shading settings panel and add additional settings.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

Support should be full when using Alpha Blend mode and partial if using
any other blend mode (opaque / alpha clip / alpha hashed).
|
|
This commit also provide a compatibility code that will convert old
materials using Additive or Multiply Blend mode to their node equivalent.
This conversion is only done on outputs that are enabled for eevee.
|
|
Alpha blended Transparency is now using dual source blending making it
fully compatible with cycles Transparent BSDF.
Multiply and additive blend mode can be achieved using some nodes and are
going to be removed.
|
|
Both eevee_materials.c and workbench_deferred.c include eeve_lut.h which has its arrays marked as static leading to the blue_noise array being embedded into our binary twice.
This change takes the arrays out of the header and properly marks them as const since they are lookup tables and should not be written to.

Use explicit boolean flag to indicate whether flush to original data
is needed or not. Makes it possible to avoid confusion on whether an
evaluated or any depsgraph can be passed to the API.
Allows to remove depsgraph from bAnimContext as well.

I'm not sure this fixes the root of the problem. The file from the ticket
seems to have been corrupted in some way.
We MIGHT want this in 2.80.

This was a read after free error. This only fix the undefined behavior.
The result is still not correct in certain cases (see T67226).
We want to include this for 2.80
|
|
This was caused by TAA offset being computed as the 2nd sample even if the
sampling was reset afterwards.
The fix is to update the matrices after any potential reset.
|
|
The View was being reused accross different redraw (not allowed).
