Sync with playcanvas/engine main (2026-10-30) - #6
f0b64df Add AgX and AgX Punchy tonemapping (Add AgX and AgX Punchy tonemapping playcanvas/engine#9874): new TONEMAP_AGX / TONEMAP_AGX_PUNCHY constants, new tonemappingAgx chunk (GLSL + WGSL), wired into CameraFrame, camera-frame.mjs script and camera component.
Добавлены режимы тонального отображения AgX и AgX Punchy. Их можно выбирать в настройках камеры и обработки изображения, а также в примерах Gaussian Splatting.
Исправления
Исправлена синхронизация текстур Gaussian Splatting: новые потоки теперь корректно подключаются к буферам рендеринга, в том числе если текстура потока была получена до синхронизации.
Документация
Обновлены описания доступных режимов тонального отображения.
* feat: Add AgX and AgX Punchy tonemapping
TONEMAP_AGX is Blender's AgX view transform, following Filament's implementation with the 6th order sigmoid fit from iolite, so that white reaches 1. TONEMAP_AGX_PUNCHY adds Filament's Punchy look for more contrast and saturation. Both are available in GLSL and WGSL, in the camera-frame script, and in the examples' tonemapping dropdowns.
* test: Snapshot the compose shader for the AgX tonemaps
Adds TONEMAP_AGX and TONEMAP_AGX_PUNCHY to the all-tonemap combinations of the compose shader snapshot, so the two new dispatcher branches and the Punchy look are pinned. The fixture gains four entries, one per tonemap and shader language; no existing entry changes.

…at runtime (playcanvas#9876)
GSplatWorkBuffer.syncWithFormat() compared the streams' format version before and after its own
sync. GSplatStreams.getTexture() also syncs, so when a texture was fetched by name after a stream
was added, the streams were already up to date and the render targets were never rebuilt. The
new stream then had a texture but no attachment, and the copy pass never wrote it.
Track the version the render targets were built for and rebuild whenever it is behind.

Добавлены режимы тонального отображения AgX и AgX Punchy для GLSL и WGSL, а также варианты выбора в примерах. Исправлена синхронизация render targets в GSplatWorkBuffer. Обновлены настройки ESLint и версии пакетов.
Changes
Режимы AgX tone mapping
Layer / File(s)
Summary
Константы и API tone mapping src/scene/constants.js, scripts/esm/camera-frame.mjs, src/extras/render-passes/camera-frame.js, src/framework/app-base.js, src/framework/components/camera/component.js
Добавлены константы TONEMAP_AGX и TONEMAP_AGX_PUNCHY со значениями 7 и 8. Обновлены сопоставления режимов CameraFrame и документация вариантов tone mapping.
Шейдеры AgX и выбор режима src/scene/shader-lib/glsl/chunks/common/frag/tonemapping/*, src/scene/shader-lib/glsl/collections/shader-chunks-glsl.js, src/scene/shader-lib/wgsl/chunks/common/frag/tonemapping/*, src/scene/shader-lib/wgsl/collections/shader-chunks-wgsl.js
Добавлены реализации AgX для GLSL и WGSL. Режим AgX Punchy применяет степень 1.35 и усиление насыщенности. Оба режима подключают новый чанк; чанк включён в соответствующие коллекции.
Примеры и проверка шейдеров examples/src/examples/camera-frame/*, examples/src/examples/gaussian-splatting/*, examples/src/examples/shaders/shader-hatch.controls.jsx, examples/src/examples/test/global-shader-properties.controls.jsx, test/extras/render-passes/compose-shader-snapshot.*
В контролы примеров добавлены варианты AgX и AgX Punchy. Snapshot-тесты и снимки включают новые режимы для GLSL и WGSL.
Синхронизация GSplatWorkBuffer
Layer / File(s)
Summary
Версия потоков и render targets src/scene/gsplat-unified/gsplat-work-buffer.js, test/scene/gsplat-unified/gsplat-work-buffer.test.mjs
GSplatWorkBuffer сохраняет версию потоков, использованную при создании render targets. syncWithFormat пересоздаёт targets, если сохранённая версия не совпадает с текущей. Добавлены тесты для добавления потока до и после вызова getTexture().
Конфигурация lint и версии пакетов
Layer / File(s)
Summary
Настройки ESLint и версии пакетов eslint.config.mjs, package.json, examples/package.json
Из конфигурации ESLint удалены глобальная переменная mocha и переопределения двух правил для тестов. Обновлены версии пакетов engine и examples, а также @playcanvas/eslint-config.
SashaRX/engine#5 — обновляет предыдущую версию пакета и snapshot-записи для compose-шейдера.
Suggested reviewers: mvaligursky
Merge Risk: Minimal · up to 97c11
The new test should follow the documented nesting convention. No material merge-blocking risk is established.
Security architecture risk: Low · up to 97c11
The changes extend predefined rendering choices and repair runtime buffer synchronization without an identified increase in privileges or trust-boundary reach. Remaining uncertainty concerns graphics-resource failure recovery rather than an established new security issue.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The examined changes affect caller-selected rendering variants and the render targets owned by a GSplat work buffer. Their demonstrated propagation is within rendering consumers; the supplied high-fanout classification does not establish a cross-service or privileged boundary expansion.
Trust Boundaries and Controls
observed — Caller tone-mapping configuration selects predefined tokens and static GLSL/WGSL branches rather than becoming arbitrary shader source. The script retains its fixed string map and existing numeric passthrough. The examined example changes add fixed selection choices, while AppBase and CameraComponent changes only document the new modes.
Resilience and Maintainability Implications
inferred — Replacement destroys existing targets before constructing and initializing replacements, and the new target-version marker is assigned before completion. Exception-safe recovery is therefore not established. However, the base also advanced the stream version before replacement and could skip rebuilding on a subsequent unchanged-format synchronization, so this does not establish a PR-introduced recovery defect.

Explanation
Заголовок «Sync with playcanvas/engine main (2026-10-30)» описывает синхронизацию форка с upstream, но не называет основное изменение. В PR есть несколько значимых частей: релиз 2.24.0-beta.26, режимы тонмаппинга AgX и AgX Punchy для GLSL и WGSL, исправление пересоздания render targets для gsplat work buffer и обновление @playcanvas/eslint-config. Заголовок относится к реальному аспекту PR (синхронизация с upstream), поэтому он не является несвязанным. Однако он слишком общий и не отражает ключевые изменения.

Graphify reviewed this change.
No issues found by static checks — no coupling regressions or blocking issues in the code graph. That is not the same as safe to merge: see what was not checked.
Not checked: tests were not run; no formal proof of the changed code.
Graphify review — findings
Drops Mocha from the ESLint setup: the Mocha globals and the test-file overrides that turned off no-unused-expressions and prefer-arrow-callback are gone, so tests now follow the regular rules apart from import/order. Moves the examples to @playcanvas/eslint-config 3.0.0, which pulls in @eslint/compat, a newer jsdoc plugin and a Node ^20.19 || ^22.13 || >=24 engine requirement. The lockfile also drops the libc markers on optional native packages and syncs the root package version to 2.24.0-beta.25.
Review partial — this diff was larger than one review pass covers, so later files were not reviewed; some findings may be missing.

Замените describe('GSplatWorkBuffer#syncWithFormat', ...) на вложенные describe('GSplatWorkBuffer', ...) и describe('#syncWithFormat', ...). Это приведёт новые тесты к обязательной структуре репозитория. Согласно правилам кодирования: «Test structure: describe('ClassName', ...) → describe('#methodName', ...)».

CodeRabbit nit (gsplat-work-buffer.test.mjs describe nesting): left as is. This PR mirrors upstream playcanvas/engine main verbatim, so local edits would make the fork diverge; any fix belongs upstream.
