# ANGLE Starter Projects
|
||
|
|
|
||
|
|
For the most up-to-date list of starter projects, see
|
||
|
|
[anglebug.com](https://bugs.chromium.org/p/angleproject/issues/list?q=Hotlist%3DStarterBug). If you
|
||
|
|
decide to take on any task, write a comment so you can get in touch with us, and more importantly,
|
||
|
|
set yourself as the "owner" of the bug. This avoids having multiple people accidentally working on
|
||
|
|
the same issue.
|
||
|
|
|
||
|
|
## Refactors
|
||
|
|
|
||
|
|
### EGL Validation Refactoring
|
||
|
|
|
||
|
|
[anglebug.com/798](http://anglebug.com/798)
|
||
|
|
|
||
|
|
Move all EGL validation into separate functions in ValidationEGL.h. This opens up many possibilities
|
||
|
|
for auto-generation of entry points and is simply a cleaner structure.
|
||
|
|
|
||
|
|
### EGL Entry Point Auto-generation
|
||
|
|
|
||
|
|
[anglebug.com/2621](http://anglebug.com/2621)
|
||
|
|
|
||
|
|
Auto-generate EGL entry points and stub functions. This greatly reduces the chance of bugs in this
|
||
|
|
highly repetitive code and reduces the friction to adding new extensions.
|
||
|
|
|
||
|
|
### Support Separate Read and Draw Surfaces
|
||
|
|
|
||
|
|
[anglebug.com/2620](http://anglebug.com/2620)
|
||
|
|
|
||
|
|
ANGLE has never supported binding separate read and draw surfaces with eglMakeCurrent due to its
|
||
|
|
architecture. Some refactoring could be done to support this use case.
|
||
|
|
|
||
|
|
### Convert GLenums into typed internal Enums
|
||
|
|
|
||
|
|
[anglebug.com/2169](http://anglebug.com/2169)
|
||
|
|
|
||
|
|
Using a compact enum instead of GLenum offers type safety. Flat enums can also index into flat
|
||
|
|
arrays. We are in the process of migrating all internal GLenums into packed enums.
|
||
|
|
|
||
|
|
## Medium Features
|
||
|
|
|
||
|
|
### Add an AST Validator to the Shader Translator
|
||
|
|
|
||
|
|
[anglebug.com/2733](http://anglebug.com/2733)
|
||
|
|
|
||
|
|
An AST validator will reduce the number of bugs in our AST transforms and allow us to be more
|
||
|
|
confident about all ASTs generated by the translator.
|
||
|
|
|
||
|
|
## Small Features
|
||
|
|
|
||
|
|
### Fix shader source viewing in RenderDoc/NSIGHT
|
||
|
|
|
||
|
|
[anglebug.com/2734](http://anglebug.com/2734)
|
||
|
|
|
||
|
|
It used to be possible to view the shader source when debugging shaders in graphics debuggers but
|
||
|
|
now only the shader disassembly is available.
|
||
|
|
|
||
|
|
### Implement Android CDD Extensions
|
||
|
|
|
||
|
|
[anglebug.com/2506](http://anglebug.com/2506)
|
||
|
|
|
||
|
|
The Android CDD requires some EGL and OpenGL ES extensions from every driver. Many of them are
|
||
|
|
simply exposing the native driver's extension to ANGLE's frontend.
|
||
|
|
|
||
|
|
## Performance
|
||
|
|
|
||
|
|
### Add perf test for eglMakeCurrent
|
||
|
|
|
||
|
|
[anglebug.com/2556](http://anglebug.com/2556)
|
||
|
|
|
||
|
|
Many customers switch Contexts frequently. MakeCurrent shows up as a hotspot. A performance test
|
||
|
|
would protect against regressions.
|
||
|
|
|
||
|
|
### Refactor std::maps into Static Arrays
|
||
|
|
|
||
|
|
[anglebug.com/1389](http://anglebug.com/1389)
|
||
|
|
|
||
|
|
ANGLE uses internal global maps for texture tables. We should rewrite them to save on binary size
|
||
|
|
and optimize startup time.
|
||
|
|
|
||
|
|
## Maintenance
|
||
|
|
|
||
|
|
### Add a presubmit python script
|
||
|
|
|
||
|
|
[anglebug.com/2626](http://anglebug.com/2626)
|
||
|
|
|
||
|
|
This simple script could verify that there is no diff on git cl upload. This saves developer time
|
||
|
|
in the long run.
|
||
|
|
|
||
|
|
## Conformance
|
||
|
|
|
||
|
|
### Vulkan ES2 fixes
|
||
|
|
|
||
|
|
[anglebug.com/2615](http://anglebug.com/2615) - see open blocking bugs. Also
|
||
|
|
[this link](https://bugs.chromium.org/p/angleproject/issues/list?can=2&q=Renderer%3DVulkan+-has%3Aowner&colspec=ID+Type+Status+Priority+Feature+Owner+Summary&cells=ids)
|
||
|
|
for open issues.
|
||
|
|
|
||
|
|
Many small edge cases still need attention.
|
||
|
|
|
||
|
|
### WebGL Conformance on Windows
|
||
|
|
|
||
|
|
[tracking document](https://docs.google.com/spreadsheets/d/1NQePFOdCKT1WKG2P4Qt8igLrLVy4U3vLOLvVWwbkllw/edit?usp=sharing)
|
||
|
|
|
||
|
|
ANGLE is preparing to release its OpenGL backend on Windows in Chrome using the passthrough command
|
||
|
|
decoder. There are still some failing WebGL tests.
|
||
|
|
|
||
|
|
### EGL Conformance
|
||
|
|
|
||
|
|
[anglebug.com/2623](http://anglebug.com/2623)
|
||
|
|
|
||
|
|
ANGLE's EGL implementation has a lot of holes in it's conformance. There are many tests that fail on
|
||
|
|
all platforms due to bugs in ANGLE's EGL frontend.
