* Don't force masked blending for transmission/volume materials
glTF lets you choose your own alpha mode when using the transmission
and volume material extensions. We were forcing the masked mode which
was incorrect, except to pass the standard tests.
* Update release notes
- separate out the settings for bloom, ssao and ssr
- update webgl binaries
- change default bloom resolution to 384 from 360 to have up to 7
mipmap levels vertically
- don't rely on it being 32-bits
- update the jni code to store SamplerParams in a long (64 bits)
instead of a int. This gives us some future-proofing of the java side.
The crashes are triggered by spirv-opt's MergeReturnPass, so we
just disable it. This pass also caused issues with AMD drivers on macOS.
fixes b/291140208
We were waiting for programs from both queues to be compiled before
calling the callback associated with one queue. In practice this caused
the callback associated with high priority programs to be called only
after low priority programs were ready.
Also cleanup-up "token" so that it doesn't store the priority.
Update the documentation and sample to better reflect what the
implementation does.
This PR sets up the ability for shaders to use `gl_ClipDistance`, which will be needed in the future. Desktop GL supports this natively. OpenGL ES requires the EXT_clip_cull_distance extension.
Unfortunately glslang does not support this extension, so we have to employ a workaround for mobile when going through glslang. We instead write to `filament_gl_ClipDistance`, and then modify the SPIR-V to decorate this as `gl_ClipDistance`. See the comment in SpirvFixup.h.
Note this PR does not actually use `gl_ClipDistance` yet, so there should be no change to shaders.
It supports KHR_parallel_shader_compile as well as a
thread pool of GL contexts.
- we have a new 2-priorities queue for shader compilation
- use this feature in gltfio in the ubershader case
the math needs to be maintained in highp, including during the blur
pass.
we add the ability to specify a "precision" qualifier to the "output"
of a post-process material.
we also remove the mediump clamping we used to do on mobile, it shouldn't
be done automatically behind the scenes, it's up to the shaders to do
it if it makes sense.
this is implemented by here by using the skybox texture and blurring it
with the irradiance filter + mipmapping. This only creates a subtle
anisotropic phase-function effect.
* froxelizer doesn't use textures anymore
All data is stored in UBOs.
Additionally, the buffer size is no longer hardcoded at compile time.
This CL cuts in half the numbers of froxels to accommodate devices
limited to 16KiB,
* Use a specialization constant to adjust the size of froxel UBO
This really only affects OpenGL in practice because metal supports 256MB
minimum and only 3% of android devices support less than 32K, which is
what we need.
This works by making the fog an entity which can be used to create
a TransformManager component an participate to the transform hierarchy.
This feature can be used as more advanced way to set the fog's floor,
which now can have an orientation (essentially be a plane).
This is useful for coordinate systems that are not y-up.
Material::compile() can be used to asynchronously ask the backend to
compile a subset of the variants of a Material and be notified when
done. This can be used during initialization to avoid hiccups later.
This will also force caching of those material programs if the
Platform provides the blob cache API.
