- **Stars**:
- Implemented procedural stars using hash-based noise.
- Added UI controls for Star Density and Enable/Disable.
- Tuned star brightness (reduced intensity) and refined twilight fade timing (visible during nautical twilight).
- Improved compositing with aggressive cloud occlusion and non-linear fade.
- Added star reflections to water, strictly masked to the horizon line.
- **Heat Shimmer**:
- Fixed horizon artifacts by decoupling shimmer from atmospheric density (Mie scattering).
- Implemented FBM-based view distortion for heat waves.
- Added sun elevation fade (shimmer fades out as sun rises > 30°).
- **Water**:
- Implemented Finite Difference normal calculation as a high-quality fallback when "Derivative Trick" is disabled.
- Added "Octaves" parameter to control wave detail.
- Refined reflection logic to handle stars and sun disk properly.
- **System**:
- Updated [simulated_skybox.mat](cci:7://file:///Users/mathias/sources/git/filament/docs_src/src_raw/wip/sky/simulated_skybox.mat:0:0-0:0) with new material parameters (`starControl`, `waterControl`).
- Refactored JS bindings in [SimulatedSkybox.js](cci:7://file:///Users/mathias/sources/git/filament/docs_src/src_raw/wip/sky/SimulatedSkybox.js:0:0-0:0) and organized `main.js` UI into logical folders.
DOCS_FORCE
- Add documentation for specgen along with proper math rendering
- Adjust the heading size, capitalization of various READMEs.
- Add backend test README to the doc
- Rename the CI related tests to have prefix "CI:"
- Reorder the release-related documents into one heading.
- Added CocoaPods README as part of the documentation.
- Fixed typo for renderdiff doc
- Added backend test doc
For reasons unknown, selenium will freeze when trying to make
request to the local server serving the markdown files. We add
a delay between the server and the selenium driver to hopefully
address this.
DOCS_FORCE
The breakage is due to breaking changes in the latest version.
We use the repo checked-in version instead.
Also make sure postsubmit.sh script exits on any error
This change adds support for the KHR_materials_dispersion glTF extension, which introduces a dispersion property for refractive materials.
The dispersion property controls the angular separation of colors transmitting through a refractive object, allowing for more realistic rendering of materials like glass and diamonds.
Changes include:
- Added a dispersion property to the material definition.
- Updated the shaders to incorporate the dispersion effect in the refraction calculations.
- Added a new test case for dispersion.
- Updated the material documentation to include the new dispersion property.
Building tools separately is necessary for the existing
cross-complation usecase. We generalize this by introducing
two cmake vars that enable exporting and importing
prebuilt tools.
The intended usecase is to enable ASAN-built filament without
having to run ASAN-built matc (which is prohibitively slow).
build.sh has been modified to add a `-y` flag forprebuilding
tools.
- Also modify update script
- Renamed to update_remote_ui
- Repair path inside sciprt
- Ensure update script is not copied over to /docs
- Add requirements.txt (for python/pip dependencies)
If we assign the message (which might contain quotes) to an
environment variable and then echo it, this should prevent the
problem of having a double quote (").
Also fix a problem in docs script for checking TAGs in commits.
- Allow for presets to override selected models when presented
in order.
- Add 'gltf' for model search path
- Add a few simple gltf models to the 'base' preset
- Improve UI so that missing tests do not generate any html
bits.
- Add documentation on using the viewer
- Add renderdiff documentation to the project webpage.
RDIFF_BRANCH=pf/renderdiff-enable-webgpu
- Fix broken links in https://google.github.io/filament/main/
- Make /README.md links consistent
- Add additional replacement recipes for /README.md
- Make /index.html redirect to /dup/intro.html because
/index.html has the wrong relative links. This is essentially
adding a redirect-only index.html to src_raw.
The new `linearFog` material property, when set to `true` enables a
simplified fog calculation. The fog equation becomes linear which is
unrealistic, but more efficient to compute. In some situations with
a shallow fog range, it doesn't make a huge difference visually.
In this mode, height falloff and in-scattering are ignored.
The linear equation slope is calculated from the regular parameters to
match the slope of the real equation at a camera height. If
`heightFalloff` is disabled, set to 0, the `density` parameter
exactly corresponds to the slope of the equation in [1/m] units.
- Add github link to page
- Fix link in contributing.md
- Small update to docs_src/README.md
- Remove logo in the core docs
- Move branching.md and release_guide.md to /docs_src
- Add "under construction" warning for the web samples
- Update matdbg README.md
- Move directories into more descriptive organization
- src_mdbook, src_markdeep, src_raw
- mdbook will be generated from mdbook
- markdeep will be generated to html
- raw will be copied without modification
- Add script that will run on a succesful commit to main. This
script will update /docs and commit the changes.
- Re-enable docs presbumit check (checks if there has been direct
edits of /docs).
- Fix script to download and install mdbook
- Update Materials.md.html and re-run the build script
(build/run.py).
* materials: introduce mutable spec constants
Rationale & design of this feature has been discussed internally.
The current implementation uses a `FixedCapacityVector` to store the new program
handles, but I wouldn't object to replacing it with a hasmap as discussed
offline.
I have compiled but not tested this yet on Android, so I'm not certain that the
API bindings are correctly wired up.
* materials: mutable spec constant feedback
* materials: address mutable spec constant comments
* Revert "Optional CMake flag for enabling ASAN for backend and its tests. (#8696)"
This reverts commit 543b93939a.
There were other already existing ways to achieve this without the need for new flags.
* Add documentation on running with ASAN and leak detection on mac.
