This includes a small change to our custom material task because old
gradle passed only the contents of out-of-date directories, newer gradle
passes both the contents and the directory itself.
* Add new shading model to Filament for specularGlossiness.
This adds a shading model based on KHR_materials_pbrSpecularGlossiness.
The corollary gltfio change will be in an upcoming PR.
* Improve documentation for specular-glossiness
* MaterialInstance now has setMaskThreshold for convenience.
* Materials now support dynamic doubleSided property.
This does not change the format of material packages because they
already have both getDoubleSided() and getDoubleSidedSet().
The only way in which this change could impact existing applications is
that materials that explicity set doubleSided to "false" will now
respect the material's culling mode, rather than forcing it to NONE.
Fixes gltf_viewer with littlest_tokyo in ubershader mode.
Fixes#963.
* JNI for dynamic material properties.
* Add underscore prefix to internal material params.
* Remove un-needed mat info field.
- "stable" mode disables all resolution optimizations that can affect
stability of the shadow map (e.g. lispsm, focusing)
- expose near/far hint + stable option to java
* Add postLightingColor property to materials
This property can be used to modify the color computed in the lighting
passes of the materials. That color is blended with the computed color
according to the postLightingBlending option (add, transparent or opaque).
* Remove test
* Update docs
* Address code review comment
* Switch postLightingColor default blend mode to transparent
In this first step, we just "blindly" move everything under src/driver
to a new library libbackend.a. And all headers are moved under
private/backend.
Note that "driver" is renamed "backend", but namespaces are unchanged for now.
Later we'll have to untangle the actual private headers from public
ones and ideally not have any private headers.
It's now possible to enable/disable tone-mapping, fxaa, msaa and
dynamic resolution independently.
A new set/getToneMapping() method is added to View.
It's still possible to disable *all* these post-processing effects
together using setPostProcessing(). This is currently needed when
rendering a transparent view (such as UI) on top of another view.
This limitation might be addressed in the future.
This fixes#621
Filamat public headers were including a private header. This PR fixes
this problem. It also forces filamat to always be compiled to avoid
breaking filamat without noticing. The flag `-l` is not available
anymore in build.sh as a result.
- EngineEnums.h is not a private headers as it contained mostly private
stuff
- MaterialEnums.h is still public, but now only contains public stuff.
Private parts were moved to MaterialEnums.h or MaterialBuilder.h
- And finally SamplerBinderMap is moved under private/ as well, since
it's certainly not a public API.
With this change, the public headers of filabridge become more reasonable
and limited.
This moves our existing VertexBuffer utility into a new "geometry"
library and adds new functionality for computing tangents based on UV's.
The UV-based method comes from Eric Lengyel.
We considered mikktspace (which thankfully has a zlib-style license) but
it would require re-indexing via meshoptimizer and is therefore a bit
heavyweight.
The new library has no dependencies and will add only 7 KB to Filament's
Android aar file.
Fixes#858 and preps for #528.
* Android standalone toolchains are not longer necessary
The latest NDK (19) contains ABI/API level specific command line
tools making standalone toolchains unnecessary. This change adapts
to the new model which greatly simplifies the build script and
ensures the latest version of the tools is being used.
Note that this requires a fairly recent version of CMake which fixes
a bug related to ranlib. This change was tested with CMake 3.13
(CMake 3.7 does not work).
* Modify CI build script to fetch recent CMake
* Remove dependency on standalone toolchains in Windows README
* Use correct CMake path
* Update NDK to latest
* Only download CMake and NDK for Android builds
* Add version constant for ninja
* Make output more quiet
The bug was reproduced and the fix was verified by copying the following
code snippet into one of our Android samples:
val norm = floatArrayOf(1.0f, 0.0f, 0.0f)
val tang = floatArrayOf(0.0f, 1.0f, 0.0f, 1.0f)
val expected = floatArrayOf(0.5f, 0.5f, 0.5f, 0.5f)
val resultBuffer = FloatBuffer.allocate(4)
val qtc = VertexBuffer.QuatTangentContext()
qtc.quatCount = 1
qtc.quatType = VertexBuffer.QuatType.FLOAT4
qtc.outBuffer = resultBuffer
qtc.normals = FloatBuffer.wrap(norm)
qtc.tangents = FloatBuffer.wrap(tang)
VertexBuffer.populateTangentQuaternions(qtc)
Log.e("Filament", "${expected[0]} == ${resultBuffer[0]}")
Fixes#695.
Amazingly, the size field in PixelBufferDescriptor was often totally
incorrect for Java-based clients. The reason we did not notice: OpenGL
often consumes a pointer to image data without consuming a byte count
(e.g. glTexImage2D).
OpenGL infers size from dimensions + format, but Vulkan does not. This
caused texture corruption with Vulkan on Android.
This fix follows a pattern used in other places such as
FRenderer::readPixels.
* Fix the Android filamesh file loader
The loader was not updated to support the SNORM16 format now sometimes
used to encode UV sets in filamesh files.
Fixes#708
* Update android/samples/image-based-lighting/app/src/main/java/com/google/android/filament/ibl/MeshLoader.kt
