This can have a dramatic effect on SSAO and needs
to be adjusted based on the scene's scale/units.
The default value used to be about 6cm, and has
been changed to 5mm.
* WIP New tone mapper API
* Implement tone mapper constructors and destructors
* Add new genertic tone mapper
* Make the generic tone mapper available in our sample UIs
* Fix warnings and crashes
* Fix generic tone mapper and graph mappers in the UI
* Add Java APIs for ToneMapper
* Implement copy/move operators for GenericToneMapper
The API now allows to create a standalone SkinningBuffer containing
Bones for skinning. This SkinningBuffer can even be very large and
contain bone data for several renderables.
New APIs on RenderableManager allow to switch to skinning buffer mode
and to set the SkinningBuffer (and window into it) to use.
Fixes#3238
* Generalize luminance scaling in color grading
Previously the luminance scaling step was tied to a specific tone
mapping operator, called "EVILS" in the API. This was however
somewhat misleading as EVILS really is a color handling system
that's independent of what we call tone mapping.
This change splits the luminance scaling step from the tone mapping
step, allowing the use of luminance scaling (the LICH part of EVILS)
with any tone mapping operator.
As a result, the operator known as EVILS is currently mapped to the
linear operator and renamed to "RESERVED" until it is replaced by
a proper — configurable — operator.
* Update release notes
* Fix web build
* Add new sample app: image_viewer
This app shows how to load and visualize images. It's also useful to work
on color grading and other post-processing effects by just loading an HDR
or EXR image as a reference.
This change also adds a new exposure setting to the color grading LUT.
* Fix comments and build
* Fix Metal
* Use high precision for the UV coordinates
* Fix refactoring issue
* API CHANGE: honor user-defined precision, rename SamplerPrecision.
matc now honors 'precision' on non-samplers in mat files, and
the filamat API now allows clients to specify precision for
non-samplers.
This involved flattening a union that is internal to filamat.
* MaterialBuilder: Add Java bindings for precision.
* Remove support for Java/desktop builds
These builds are never tested nor used on our end. We cannot
guarantee their proper support. It should also be possible
for an app to handle this itself.
* Remove Tungsten since it cannot be compiled anymore
This adds some significant JNI glue in order to make the Java API for
gltfio materials much more consistent with C++, and create feature
parity between the two languages.
The motivation is to allow Java clients to provide their own
ubershader-based solution or filamat-based solution.
- The `MaterialProvider` Java class is now an interface.
- The `UbershaderLoader` Java class is now a concrete implementation.
- Users can now write their own provider class using Java / Kotlin.
To streamline the amount of JNI work that occurs at run time, the
MaterialProvider Java interface uses ints in a couple spots instead
of enums. This sacrafices some readability for Java clients who wish
to write their own provider, but makes the JNI much simpler.
This replaces #3975.
- the clear color was broken since we switched dot EVSM
- use the scissor instead of the viewport, it makes it easier to compute
the uv-scale.
- the min/max lod level wasn't reset properly
- also clamp the minimum shadowmap size to 8, and document it.
This is still somewhat work-in-progress, but good enough to be useful.
Some caveats:
- large blurs don't work well with cascades
- the implementation uses more memory than it could
This allows clients to obtain the extras strings for the asset and
for individual nodes. Note that extras for buffer views, accessors, etc
are not supported, although C++ clients can access the raw cgltf data
directly if they need to.
- use EVSM (exponential VSM), helps a lot with light bleeding
- don't apply shadow biases with VSM
- improve VSM user settings: added more controls, expose to java
- minor code cleanups:
- rename some structures
- remove unused parameters
- remove unused uniforms
This reworks how we compute the bloom buffer size. The main changes are:
- The BloomOptions.resolution is changed to height instead of minor axis.
This keeps a consistant look of the bloom regardless of the viewport.
- The anamorphism setting now dilates the bloom rather than to compress
it (in the other direction), which maintains the same amount of bloom.
However, the resolution decreases meaning that the user might need to
adjust resolution and/or levels.
- limit the resolution do 2048 which is gles minspec.
* Materials can now provide custom lighting/shading
When a material uses the "lit" shading model, customSurfaceShading can
be enabled to replace Filament's lighting implementation. When this
feature is enabled, the material *must* provide the following function
in the fragment shader block:
vec3 surfaceShading(
const MaterialInputs materialInputs,
const ShadingData shadingData,
const LightData lightData
) {
return vec3(1.0); // custom lighting here
}
Please refer to the docs in Materials.html for more information about
this feature and the different values provided by the data structures
passed to the function.

More precisely, this logs the time that the Filament backend takes
to process all the commands that were issued in the gltfio synchronous
loading phase, which mostly consists of creating and populating vertex
buffers.
This can be quite slow for vertex-heavy (CAD-style) models, and seems to
vary by several orders of magnitude from device to device on Vulkan.
The sample would crash when removing `orientation` from `configChanges`
and rotating the device, because the old RemoteServer would still be
alive when creating the second one, so the WebSocket port would be
unavailable.
* a way to keep the content of custom RenderTarget attachments
Until now, all attachments of RenderTarget beyond COLOR0 were discarded
after rendering.
With this change, attachment whose texture has the SAMPLEABLE usage
bit set will be kept.
