deprecated Texture(long nativeTexture) in favor of
Texture(Engine, long nativeTexture), there is no difference
currently, but in the future Texture(Engine, long nativeTexture)
will be able to validate the native pointer.
The JNI layer already does this, but can only track objects it created,
sometimes developers might create filament objects on the native side
and wrap them into java objects and this might cause a failure to
detected when objects are double-destroyed.
However, this can often be caught by the native code -- so, when the
native side is asked to destroy an object that doesn't exist, we now
return an error (exception if enabled) and we throw an exception
on the java side.
Filament typically doesn't do this kind of tests, however these bugs
can be very hard to find, and the cost is small.
When no name is provided during instance creation, it does NOT inherit
the name of its parent material. This is because instances should be
lightweight and users can already do instance->getMaterial()->getName().
In a subsequent PR, this feature will be exercised and tested via the
gltfio AssetLoader.
Fixes#2485.
- we were allocating objects with a destructor in the command stream
which is always invalid because there is no guarantee that when
the callback is called, the underlaying memory is still valid
(and it wasn't).
- AutoBuffer move-ctor wasn't moving some of its state, which would
lead to destroying the same ref several times.
- bokeh rotates with the aperture diameter
- match sample count on cpu and cpu sides which affects CoC calculation
- feather blur radius to avoid visible "steps" in bokeh size
- contact shadows are now supported for point and spot lights
- and are now independent from regular shadows, that is they can
be enabled without enabling regular shadows
The only limitation currently is that the distance and step count for
ALL contact shadow are taken from the directional light options.
Static JNI lookups were causing issues with multiple libraries.
We now do the lookups when we need them as they are effectively
just hashmap lookups and we do them only in places where the
work we need to perform will be much larger than a simple hash
map lookup anyway.
This chane also manually registers filament-utils JNI bindings
to get rid of unnecessary symboles. We should do the same for
other Filament libraries (the symbols are pretty long and
we now have many of them).
ignoring beginFrame() return value is allowed, but doing so would
leave filament in an invalid state.
we now make sure that we don't execute any code after determining whether
the frame should be skipped, and execute the remainder of beginFrame()
upon the first call to render(View*).
We also make sure the FrameSkipper can deal with its endFrame() being
called when the current fence hasn't signaled.
* API BREAKAGE: this change aims to fix multi-view support
What has changed:
- View doesn't have a notion of clear color anymore
- View doesn't have a notion of discard flags anymore
- The clear color and color-buffer discard/clear flags are moved to Renderer
- Skybox can now be set to a constant color
- View have a blend-mode
What does is all mean:
"Clearing" (i.e.) setting its background is now handled by Skybox, by
setting a constant color to the Skybox. This should take care of
drawing views side by side.
When a view needs to be drawn on top of another, it's BlendMode needs to
be set to TRANSLUCENT and of course and, generally, it wither won't have
a skybox, or will have one that sets some translucent pixels.
As an optimization, a View with BlendMode::OPAQUE will have its
background cleared with the color specified in Renderer.
If the SwapChain already has some content, it's now possible to set
the Renderer to not discard the content, together with TRANSLUCENT views,
it's possible to draw on top of that content.
It is NOT possible to share depth/stencil buffers between views.
Fixes: #2369, #2372, #2364
* Address reviewers comments.
Note: WebGL is still broken with this PR
* Expose Java API to control discard flags
This change also adds the new sample sample-multi-view that shows
how to use discard flags to render multiple views.
* Disable clears
The user can now choose amongst 3 specular AO methods:
- None, specAO is off
- Simple, specAO is inferred from roughness and diffuse AO
- Bent normals, specAO is computed accurately from cone intersections
The last method is more expensive but produces the best results.
This change also fixes a few issues:
- Rename materialRefraction() and materialRefractionType() for
consistency
- Fixes user time in shaders
- now the DynamicResolutionOptions don't specify the target frame rate,
they only specify how to scale this given view
- there is a new FrameRateOptions setting on Renderer, which is used
to specify the desired target frame rate for the whole Renderer
- the frame rate is now specified as a "frame interval" in units of
the display frame period.
- the display frame period is (indirectly) set via DisplayInfo.
In other words, the use must set (and update) DisplayInfo properly
(the default are reasonable, but assume 60 Hz). They must also set the
desired interval (default is 1, which is probably what you want).
Finally they must enable dynamic scaling per View, the defaults are
also reasonable.
Currently Renderer doesn't attempt (yet) to actually target the
requested frame rate, so it's up to the caller to push frames at the
desired speed. however, dynamic resolution, like before, will attempt
to shrink work to fit the target.
Renderer can now be given a DisplayInfo that contains some
important information about the current display. This will be used
for frame-pacing and dynamic-resolution.
This is most relevant on Android, where we can accurately query these
parameters. Added support for that in our samples.
This also sets the minSDK to 19 (including gltf viewer's), since this is
the version we support. We were cheating before by under-reporting our
minSdk.
