WGPU Migration Plan (BGFX Replacement) + +## Scope +- Replace `bgfx` with a Rust `wgpu` backend across Babylon Native. +- Keep current feature parity for NativeEngine + NativeXR. +- Enable BabylonJS WebGPU execution path on native targets. +- Preserve platform coverage: Android 10+, iOS, macOS, and Windows 10. +- Rebase long-term backend implementation onto upstream `wgpu-native` to avoid + maintaining a local fork-like Rust implementation. + +## Module Ownership Map (for reviewers) +- `Core/GraphicsWgpu`: + owns backend lifetime (instance/surface/device/queue/present path) and exports + the shared Rust C ABI (`babylon_graphics_backend`). +- `Plugins/NativeWebGPU`: + owns JS-facing `navigator.gpu` module surface and forwards WebGPU/interop calls + to the shared GraphicsWgpu ABI. +- `Polyfills/CanvasWgpu`: + owns JS-facing Canvas subset (`Canvas`, `Context`, `Path2D`, etc.) and forwards + Canvas draw operations to Rust/femtovg; `getCanvasTexture()` returns a native + texture handle consumed by `GPUQueue.copyExternalImageToTexture(...)`. +- Relationship: + `NativeWebGPU` and `CanvasWgpu` are peer JS modules; both use + `Core/GraphicsWgpu` as the single backend target so the process links one + wgpu runtime graph. + +## Progress Update (current branch) +- Added a root Rust workspace (`/Cargo.toml`) centered on + `Core/GraphicsWgpu/Rust`, with CanvasWgpu Rust source consumed as an in-crate + module from GraphicsWgpu so there is a single dependency graph and lockfile + (`/Cargo.lock`) for the linked backend. +- Unified Rust build artifacts under top-level build output (`${CMAKE_BINARY_DIR}/cargo`) + and removed inline Rust-target lockfiles from source subdirectories. +- Removed separate CanvasWgpu Rust crate build wiring; CanvasWgpu Rust exports + are compiled into `babylon_graphics_backend` so only one Rust static backend + target is linked into native binaries. +- Implemented `CanvasWgpu` filter blur execution (blur-only CSS filter path) + and exposed native canvas interop handle export through `getCanvasTexture()`. +- Wired Playground WebGPU smoke script to render Canvas gradient+blur+text and + push the native canvas handle into the WebGPU canvas-texture path. +- Added native bridge function + `babylon_wgpu_import_canvas_texture_from_native(...)` + (with `babylon_wgpu_set_debug_texture_from_native(...)` alias retained) to + import CanvasWgpu output into GraphicsWgpu cube sampling (used by + `GPUQueue.copyExternalImageToTexture(...)` internals). +- Added optional upstream `wgpu-native` source integration (`FetchContent`) behind + `BABYLON_NATIVE_WGPU_USE_UPSTREAM_NATIVE`, with Rust link wiring so the + GraphicsWgpu backend can consume upstream staticlib artifacts. +- Added explicit `webgpu-headers` FetchContent wiring (pinned to the commit used + by upstream `wgpu-native`) and switched shim bindgen include resolution to use + that source-of-truth header path instead of relying on nested vendored copies. +- Added a shared internal C ABI declaration header + (`Core/GraphicsWgpu/InternalInclude/Babylon/Graphics/WgpuInterop.h`) so + `Core/GraphicsWgpu` and `Plugins/NativeWebGPU` consume one declaration source + for Rust-exported `babylon_wgpu_*` entry points instead of duplicating local + extern declarations. +- Added canvas-prefixed texture-import/stats C ABI entry points + (`babylon_wgpu_import_canvas_texture_from_native` and + `babylon_wgpu_get_canvas_texture_*`) and switched NativeWebGPU to those names + while retaining debug-prefixed aliases for compatibility. +- Replaced NativeWebGPU `GPUQueue.copyExternalImageToTexture` no-op with a + standards-aligned bridge that accepts Canvas-like external image sources and + routes them through the shared canvas texture import path. +- Gated non-standard `navigator.gpu` hooks behind Chromium/WebKit-style + developer flags: + `BABYLON_NATIVE_ENABLE_WEBGPU_DEVELOPER_FEATURES` and + `BABYLON_NATIVE_ENABLE_UNSAFE_WEBGPU`. +- Removed in-build patching of upstream `wgpu-native/Cargo.toml`; upstream is now + consumed read-only and built as staticlib via Cargo/rustc flags from CMake. +- Converted the `upstream_wgpu_native` feature seam from no-op to active probe: + backend init now records upstream `wgpu-native` version via `wgpuGetVersion()` + and includes that metadata in adapter diagnostics. +- Expanded the upstream probe to use `wgpu-native` C ABI request flows + (`wgpuInstanceRequestAdapter` + `wgpuAdapterRequestDevice` + `wgpuInstanceProcessEvents`) + so adapter/device bootstrap viability is validated through upstream primitives + before local fallback path execution. +- Updated async wiring assumptions for current upstream behavior: target builds + treat `WGPUFuture` IDs from adapter/device/map/error-scope/pipeline async calls + as optional metadata (`NULL_FUTURE` is expected today), and rely on callback + completion + `wgpuInstanceProcessEvents` instead of `wgpuInstanceWaitAny`. +- Removed production `std::async` usage from NativeWebGPU Promise APIs (kept only + under test hooks) and switched to JS-runtime deferred dispatch to cut thread + churn and hot-path heap pressure. +- Optimized debug canvas texture import path to reuse GPU texture resources when + dimensions are stable, avoiding per-frame texture/view/bind-group rebuilds. +- Added native readback staging-buffer reuse and CPU upload-buffer recycling in + the debug canvas-texture import path, eliminating per-frame GPU/heap buffer + allocations while preserving texture import behavior. +- Eliminated a CanvasWgpu hot-loop allocation leak by avoiding render-target + recreation when width/height/DPI are unchanged across `nvgBeginFrame`. +- Added native `destroy` aliases for CanvasWgpu `Canvas` and `Context` objects, + and wired disposal to release retained JS context references. +- Reduced NativeWebGPU per-frame JS wrapper churn by caching shared no-op and + draw-marker callbacks instead of creating new function objects repeatedly. +- Reworked local fallback compute dispatch to reuse a persistent device/queue + and cached compute pipeline, removing per-dispatch adapter/device setup. +- Reworked upstream `wgpu-native` compute dispatch path to reuse a persistent + runtime (instance/adapter/device/queue) plus cached pipeline, removing + per-dispatch bootstrap and reducing hot-path allocation churn. +- Inlined upstream `wgpu-native` C ABI bindings/dispatch logic into the + primary GraphicsWgpu crate (`Core/GraphicsWgpu/Rust/src/lib.rs`) and removed + the separate `upstream-shim` crate boundary from the workspace/dependency + graph to avoid split ownership and duplicate crate wiring. +- Moved local `wgpu` runtime bootstrap ownership (instance + adapter/device + selection/retry) into the same shim crate and switched `create_context` to + consume shim-managed bootstrap results, reducing duplicate runtime ownership + logic in `Core/GraphicsWgpu/Rust/src/lib.rs`. +- Moved depth/offscreen target creation and dimension clamping into shim-owned + `LocalRuntimeState` helpers so local backend context code no longer duplicates + those lifecycle/guard utilities. +- Moved local surface creation/configuration helpers into the shim crate + (`create_local_surface` + `configure_local_surface`) so `create_context` + remains focused on Babylon-facing context assembly while preserving behavior. +- Moved `create_context` bootstrap wiring (`instance/surface/probe/runtime/ + surface-config/format resolution`) into shim-managed + `bootstrap_local_context`, leaving local `lib.rs` focused on Babylon pipeline + assembly and per-frame behavior. +- Moved adapter identity resolution (backend/vendor/device/name fallback) into + shim bootstrap output, so `create_context` no longer duplicates local-vs- + upstream adapter mapping logic. +- Moved surface-frame acquisition and queue submit/present handoff into the + shim (`acquire_surface_frame_view` + `submit_and_present`) so the local + render loop uses shim-managed present semantics with less duplicated + surface-error handling. +- Moved runtime+renderer ownership into a shim-managed + `InteropBackendContext` (bootstrap/resize/render/install-debug-texture), + leaving `Core/GraphicsWgpu/Rust/src/lib.rs` focused on Babylon FFI, error + propagation, and telemetry state. +- Moved surface reconfigure path into shim (`reconfigure_local_surface`) so + surface lifecycle operations (configure/reconfigure/acquire/present) are now + consistently shim-owned. +- Introduced shim-owned `LocalRuntimeState` and migrated local backend context + ownership to that runtime struct (device/queue/surface/surface-config/ + adapter metadata), reducing duplicated bootstrap/lifecycle fields in + `Core/GraphicsWgpu/Rust/src/lib.rs`. +- Added persistent upstream bootstrap runtime initialization (`instance` + + `adapter` + `device` + `queue`) in the shim and switched feature-enabled + `create_context` probe path to consume that runtime. +- Extended upstream shim coverage with real surface-backed adapter probing + (`wgpuInstanceCreateSurface` for Metal/Android/Win32 + adapter request with + `compatibleSurface`) and switched `create_context` probe path to use it when + a platform surface handle is available. +- Added upstream surface lifecycle probe (`wgpuSurfaceGetCapabilities` + + `wgpuSurfaceConfigure` + `wgpuSurfaceGetCurrentTexture` + `wgpuSurfacePresent` + + `wgpuSurfaceUnconfigure`) to validate queue/present-path viability through + upstream C ABI before local fallback rendering path. +- Removed the remaining inline fallback shim definitions from + `Core/GraphicsWgpu/Rust/src/lib.rs`; shim dependency is now always present, + with upstream behavior selected via crate features. +- Switched root default to `BABYLON_NATIVE_WGPU_USE_UPSTREAM_NATIVE=ON` for this + branch and removed the large non-upstream compute fallback in the shim, + reducing local duplicate runtime logic while keeping explicit compile-time + disabled stubs for non-upstream builds. +- Removed shim-only upstream surface probe/present validation helpers and + switched bootstrap probing to `ensure_bootstrap_runtime(...)` to keep the + interop layer smaller and avoid duplicate surface lifecycle validation paths + that are already exercised by live render execution. +- Added serialized backend-call gating around Rust FFI `render`/`resize`/`destroy` + to prevent resize-vs-present races observed on Android API 31 emulator + (`Surface is not configured for presentation` panic loop). +- Hardened Playground startup against script ordering races by waiting for + `createScene` initialization in the runner instead of exiting early, which + removes intermittent gray-screen launches on Android API 31 simulator. +- Removed non-standard `__nativeWebGpuReady` and `__nativeCanvasReady` globals. + The AppRuntime FIFO WorkQueue guarantees `navigator.gpu` and `_native.Canvas` + are synchronously available before any script runs, matching the W3C WebGPU + spec where `navigator.gpu` is a synchronous `[SameObject]` attribute. +- Hardened platform launcher reset scripts (macOS/iOS/Android Playground) to + clear stale WebGPU smoke globals (`__babylonPlaygroundWebGpuSmokeReady`, + `__webgpuSmokeDispose`) alongside `createScene` factory state, reducing + intermittent gray starts caused by cross-run script-state carryover. +- Added explicit WebGPU-smoke readiness signaling + (`__babylonPlaygroundWebGpuSmokeReady`) so the runner can await real + async scene/canvas-texture readiness instead of relying on retry-only startup + heuristics; this removed intermittent Android/iOS/macOS gray-start races + without blocking the JS runtime thread. +- Removed native fail-open auto-enable draw fallback in + `babylon_wgpu_render` (240-frame timeout path). Presentation is now driven by + explicit JS/native draw signals (`_markWebGpuDrawRequested` and successful + canvas-texture upload) instead of implicit frame-count heuristics. +- Fixed Playground scene bootstrap to bind Babylon scenes to the passed engine + instance (`new BABYLON.Scene(engineArg)`), removing stale-global runtime + coupling that could leave Android launches in a gray-screen state. +- Added render-loop exception guarding in the Playground runner so transient + JS-side render errors are surfaced via status callbacks and trigger runtime + recycle after repeated failures instead of leaving a silent gray frame. +- Removed extra panic/unwind wrapping from `babylon_wgpu_render` and + `babylon_wgpu_resize` hot paths and switched to direct context casts by C ABI + contract, reducing per-frame overhead on native render loops. +- Added a lock-free pending-upload gate for canvas texture handoff so the + render loop avoids mutex acquisition when no Canvas texture upload is queued. +- Aligned local `wgpu` crate usage to the upstream `wgpu-native` major line + (`wgpu` 27.x) and updated local API callsites (`FilterMode` sampler mipmap + setting, `PipelineLayoutDescriptor.push_constant_ranges`, and + `RenderPipelineDescriptor.multiview`) to keep compatibility while reducing + drift during migration. +- Hardened Android Playground launch sequencing by explicitly clearing + stale `createScene` / scene-factory globals before script load and adding + bounded async startup retries in `playground_runner.js`, reducing intermittent + gray-start races without blocking the runtime thread. +- Removed probe-only upstream bootstrap ownership from the GraphicsWgpu render + bootstrap path (`ensure_bootstrap_runtime` usage in local context creation), + keeping adapter identity sourced from the active local runtime and reducing + duplicate C-ABI validation paths in `Core/GraphicsWgpu/Rust/src/lib.rs`. +- Simplified local adapter/device bootstrap error/retry flow in + `Core/GraphicsWgpu/Rust/src/lib.rs` by collapsing duplicated retry branches + into a single helper-driven selection sequence and one Android-specific + low-power fallback retry path. +- Further reduced local bootstrap duplication by replacing platform-split + adapter selection branches with one ordered attempt plan per platform + (`ADAPTER_ATTEMPTS`) in `bootstrap_local_wgpu_runtime`, keeping behavior + while shrinking local orchestration code. +- Aligned iOS/macOS Playground script bootstrap with Android by clearing stale + global scene factory symbols before loading smoke/runner scripts, reducing + intermittent gray-start races after repeated app relaunches. +- Added explicit post-submit device polling in CanvasWgpu and tightened iOS + simulator poll mode in GraphicsWgpu submit path to improve command retirement + and reduce sustained simulator memory growth during long-running smoke loops. + +## Latest Validation Snapshot (this session) +- Visual checks (non-headless) confirmed textured cube + Canvas text on: + -
