Multisampled Anti-aliasing For Almost Free — On Tile-Based Rendering Hardware Overview Anti-aliasing (AA) is an important technique to improve the quality of rendered graphics. Numerous algorithms have been developed over the years: Some rely on post-processing aliased images (such as FXAA): These techniques are fast, but produce low quality images Some rely on shading multiple samples per pixel (SSAA): These techniques are expensive due to the high number of fragment shader invocations More recent techniques (such as TAA) spread the cost of SSAA over multiple frames, reducing the c ..read more

Overview Dependency injection is a programming pattern which prescribes that classes do not construct instances of their dependencies, instead such instances are provided. This pattern enables separation of concerns, and increases testability, reusability, and ease of maintenance. See Dependency injection in Android to review the benefits of dependency injection and its core concepts. You may already be familiar with Hilt, the Android library based on Dagger which implements a dependency injection solution for Android apps. Hilt’s approach includes two important features: Providing dependenci ..read more

Strong skipping mode is an experimental feature in the Jetpack Compose Compiler 1.5.4+ that is currently being tested. It is part of our work to make the code you naturally write more performant. We don’t want you to have to be experts in Compose internals in order to write good Compose code! Strong skipping mode changes the rules for what composables can skip recomposition and should greatly reduce recomposition by allowing composables with unstable parameters to be skipped, and additionally, automatically remembering lambdas with unstable captures. This change may seem small, but the behavi ..read more
