We now export only two groups of symbols: (1) JNI and (2) dynamic linker
symbols used by the companion libraries.
This commit has the following impact:
- Shrinks the arm64 so from 1024 KiB to 954 KiB.
- Shrinks the arm64 aar from 560 KiB to 538 KiB.
Note that the patterns in the map file are tested against mangled names
and therefore should not be used to match the double-colon operator.
Note that this API is on the loader rather than the asset. This is
because the loader knows how to create Filament entities by traversing
a cgltf node hierarchy.
Animation on dynamically added instances is not yet supported.
We did not add destroyInstance() because gltfio favors flat arrays for
long term storage of entity lists and instance lists, which would be
slow to shift. We also wish to discourage create/destroy churn since it
is more efficient to pre-allocate instances and selectively add them
into the scene.
Fixes#3137.
You can now build Filament with support for both X11 APIs, or neither.
If both are supported, run-time selection is achieved using a SwapChain
flag.
Supporting only one API at build time (or neither) is useful because our
list of "required" VkInstance extensions can vary according to which
API's are supported. During VkInstance creation, we do not have a priori
knowledge about what kinds of swap chains will be created. (headless vs
non-headless, XCB vs XLIB, etc)
Note that some Vulkan implementation (e.g. some builds of SwiftShader)
only support XCB.
- Use lower depth LOD as the cone radius increases.
This is the same technique we use for SAO.
The better cache access significantly improve performance.
On a test on Pixel4 at 585MHz, SAO pass improves by 30%.
This also helps the algorithm scale with the shadow distance.
- Shadow direction/length no longer dependent on aspect-ratio and camera
orientation.
This is fixed by doing all the computations in screen-space instead of
normalized screen space.
- Shadow parameters are no longer dependent on the field of view.
- Also rename dominantLightShadowing.fs to ssct.fs
- remove zoom parameter, it wasn't very useful.
This introduces the `viewer::Settings` struct, and a JSON reader /
writer.
This will be used for automated testing and for client / server
communication.
Note that `viewer::Settings` is closely associated with the
`filament::View` API; when updating the latter we will often need to
update the former, as well as some serialization code. This increases
the maintenance burden and I think we should consider using a parser
library like libclang or a macro-based reflection utility.
This PR also migrates SimpleViewer into libs/viewer and un-inlines its
implementation. It does not belong in gltfio because it has an imgui
dependency.
We borrow a page from the HBAO book here and allow to limit the angle
with the horizon of SSAO samples. This can help reducing the effects
of low tessellation, which tend to create unwanted creases with SSAO.
- inScatteringSize actually cannot be set to zero because it produces
a 0^0 in the shader. So with this change, in-scattering must be
strictly > 0 to enable.
- inScatteringSize on the java side had an incorrect default value of
zero (which of course, now doesn't matter anymore).
- also clamp the fog altitude to 1mm which simplifies the shader quite
a bit for the same result.
Fixes#3069
.blurScale was in fact a scale factor applied to the circle of
confusion (which makes it indeed a "blur scale", but let's use
a more precise language here).
Update comments to show how to use .cocScale to control the DoF
effect independently from the camera aperture, which can be useful for
artistic reasons.
Marking a view with a custom render target will now disable blending
for that view but require an alpha channel for intermediate buffers.
Blending is disabled because it is meaningless.
fixes#2802
Also cleanup all setImage() error reporting. All error checks are
changed from silent to NON_FATAL_ASSERT, which means they'll throw
if exceptions are enabled or do a no-op and log a message otherwise.
Also added more precondition checks.
* Add back proguard file for Android and update README.md
The proguard-rules.pro file provided by Jeff McGlynn (9fe60a636)
works perfectly for Android projects with minifyEnabled.
Add the config file back to the repository and update README.md
to help other Android users setup release build.
* Refine android proguard file and remove proguard section in README.md
