Wire up wgpu init + scene load + RAF render so the embedded sample
sidecar paints on the canvas in both browsers.
Root-cause fix: BufferPool::addSubBuffer spin-waited on
PopErrorScope, which resolves via JS microtask on Dawn-web. The
spin blocked the JS event loop, so the microtask never fired and
the first allocation hung the page indefinitely. Skip the
error-scope dance on Emscripten; trust the buffer pointer.
ViewportCore: add initWgpuAsyncWeb (nested-callback adapter→device
chain with AllowSpontaneous mode, no spin) and loadSidecarFromPath
(Qt-free entry point). waitTickInstance becomes a no-op shim on
web; cull-threads / streaming_thread_ / wgpuSurfacePresent gated
off; chunk I/O runs inline.
main_web.cpp: AppState + initWgpuAsyncWeb → buildPipelines (+
HiZ/edge/pick) → loadSidecarFromPath → ready flag → Module._app_ptr
handoff. The RAF loop lives in shell.html (NOT here) because any
RAF helper called from inside Dawn-web's wgpu Promise.then chain
stalls the device callback.
CMakeLists.txt: EXIT_RUNTIME=0 + Module.noExitRuntime=true (shell)
keeps wasm alive past main() so the device promise lands; no
Asyncify; export _raf_tick_c so shell.html's RAF can call it.

1) Async-wait spin loops in initWgpu / probeAndCreatePool / pick /
screenshot finalize all called wgpuInstanceProcessEvents in a tight
while. wgpu-native drives queued callbacks from there; Dawn-web
queues the callback for an event-loop tick that never happens
because wasm doesn't yield back to JS. Page hung at the first
await (RequestAdapter) and Firefox flagged the tab as slow.
New `waitTickInstance` helper calls emscripten_sleep(0) on
Emscripten (Asyncify unwinds wasm, JS resolves WebGPU promises,
resume) before wgpuInstanceProcessEvents drains completions into
our callback. Desktop path is unchanged. All five
`while (!done) ProcessEvents` sites switch to the helper.
2) streaming_thread_.start() inside initWgpu spawns a std::thread.
On Emscripten that needs -pthread + COOP/COEP headers from the
hosting page. None of that is wired yet, so the start is gated
`#if !defined(__EMSCRIPTEN__)`. The sync chunk-load fallback
already inside driveStreamingLoads carries the load until #88
replaces it with emscripten_fetch.
3) wgpuSurfacePresent at the end of render() aborted with
"wgpuSurfacePresent is unsupported (use requestAnimationFrame via
html5.h instead)" — Dawn-web composites the canvas at the end of
the RAF tick automatically. Call skipped on Emscripten;
WebViewportHost::requestFrame is the RAF-tick driver.
Page now loads, brings up wgpu, configures the surface, and renders
one frame with the configured background. The frame log in the
status overlay shows the first-frame startup spike (~1000 fps from
a 1 ms tick); subsequent frames are paint-on-demand, which on the
empty scene means no frames at all — consistent with the desktop
event-driven model.
Replaces the standalone wgpu-only clear-color spike in main_web.cpp
with a real WebViewportHost implementation: surface creation via the
emdawnwebgpu canvas-selector source, framebufferSize through
emscripten_get_element_css_size + dpr, requestFrame as a deferred
flag the RAF main_loop consumes, quit through emscripten_force_exit.
main_web.cpp now does the same lifecycle the desktop initWgpu shell
does: core_.initWgpu(web_limits=true) → buildPipelines → buildHiz/
Edge/Pick. The render loop runs core_.render() once per RAF tick when
the host has flagged a frame pending, with a surface reconfigure on
size changes.
Builds clean under emcc 6.0 + emdawnwebgpu (1.4 MB wasm, 278 KB JS
glue). Renders an empty scene with the configured background — the
plumbing is end-to-end through the same ViewportCore code path the
desktop build uses. No sidecar load yet: that lands with the
emscripten_fetch streaming backend (#88).
addSectionPlaneAtSurface (camera-facing auto-flip + kMaxSectionPlanes
cap check), removeSectionPlane, and clearSectionPlanes all move to
ViewportCore. ViewportWindow keeps tiny forwarders so the section
tool's input handlers (still VW) call through without seeing the move.
Each method now calls host_->requestFrame() in place of the
isExposed() + requestUpdate() gate, which means the section tool path
becomes the next piece that could exercise the WebViewportHost: a
click-to-add over WebGPU will work as soon as the host is wired,
without further core-side changes.
The frame loop — surface acquisition, parallel cull dispatch, streaming
drive, two-pass main render, HiZ resolve, edge pass, screenshot
capture, FrameStats emission, interactive / bench heartbeat, bench
summary + auto-quit — all live in ViewportCore now.
ViewportWindow::render() shrinks to the Qt-only prelude:
isExposed() guard, fpsIntegrate() (fly-mode WASD step), then
core_.render().
The overlay renderer stays Qt-bound (OverlayRenderer.h carries
QString labels). Core reaches it via two new ViewportHost virtuals:
encodeOverlaysInMainPass (section gizmos, highlights, pivot, lines,
points — in-MSAA-pass) and encodeOverlaysPostMain (corner axis,
marquee, labels — on the resolved surface). The QtViewportHost
implementation in ViewportWindow forwards each to overlays_.X().
FrameStats moves to its own Qt-free header (FrameStats.h) with
ViewportWindow::FrameStats re-exported as a using-alias so the
bonsai-side signal binding keeps working. ViewportHost::onFrameStats
replaces the placeholder 4-double signature with the typed POD.
OverlayFrame moves alongside (OverlayFrame.h) so the host overlay
callbacks can carry it without dragging Qt into core.
Bench + frame-stats + cull-tuning state (min_pixel_radius_,
motion_min_pixel_radius_, lod1_pixel_threshold_, cull_threads_enabled_,
prev_camera_*, has_prev_camera_, last_cull_was_motion_, last_visible_*,
last_cull_*ms_, last_stream_ms_, bench_*, interactive_frame_count_,
frame_time_ms_window_/_sum_/_count_/_head_) move to ViewportCore; VW
keeps reference aliases so the env-var prelude, setBenchmarkFrames,
and the various tool keybind setters keep compiling unchanged.
Smoke checks: --screenshot path renders + saves a clean PNG;
--benchmark 10 runs the warm gate, prints the per-frame log + summary,
and exits cleanly via host_->quit().
The inline screenshot path inside render() — surface-to-buffer copy,
async map, BGRA->RGBA swap into a tightly-packed RGBA8 image — moves
into core_.encodeScreenshotCapture / finalizeScreenshotCapture. render()
calls the two new helpers around its existing queueSubmit.
The PNG write itself stays Qt-bound, but it's now reached through a
new ViewportHost::saveScreenshotRgba8 virtual. The QtViewportHost
override (ViewportWindow::saveScreenshotRgba8) constructs a QImage
around the host-buffer and calls QImage::save("PNG") with the same
log lines as before; a future WebViewportHost will route the bytes
through stb_image_write or a download-URL emit instead. Either way,
the wgpu-side capture path never touches Qt again.
quit-after-screenshot now goes through host_->quit() too, so the
--screenshot CLI exit no longer reaches QCoreApplication::quit()
from render() directly.
Two small helpers + the screenshot-quit flag flip across; the render-
side capture encode + readback + PNG save itself stays in VW (those
need a stbi-style PNG writer to replace QImage::save before they can
move, and that's its own commit).
VW keeps tiny forwarders so bonsai's SceneLoader + the CLI screenshot
path don't see the move. The streaming sync-fallback gate already
reads the core-side pending_screenshot_path_, so capture timing is
unchanged.
The swapchain configuration path — WGPU_PRESENT_MODE handling,
mode-preference order (Mailbox / Immediate / FifoRelaxed / Fifo),
caps probe, cfg.alphaMode wiring, and the on-resize depth + MSAA +
HiZ texture reallocation + bind-group invalidation — all move to
ViewportCore. The only VW-side concern was a QString::fromLatin1 in
the advertised-modes log, which becomes a std::string concat with the
same output.
ViewportWindow's render() / resizeEvent / surface-outdated retry paths
call core_.configureSurface() now. createSurface() (which returns the
platform-specific WGPUSurface from the host) stays VW because Qt
platform discovery has to happen on the Qt side.
The whole pick pipeline (R32UInt + RGBA16F MRT, depth attachment,
ping-pong staging, single-pixel + rect readback) plus the public
pickObjectAt / pickSurfaceAt / picksInRect / pickMeshLocalAt / raycast
API and the rayAabbSlab / rayTriMT / rayAABBHit helpers all move to
ViewportCore. ViewportWindow keeps tiny forwarder methods so the
bonsai input + tool callers (mouseRelease, marquee, section tool,
Length/Area refinement) stay compiling.
MeshLocalPick + RaycastHit follow as nested types on ViewportCore;
ViewportWindow re-exports them as using-aliases to preserve the
ViewportWindow::MeshLocalPick / ViewportWindow::RaycastHit names
existing callers (and a couple of bonsai tests) reach for.
State migrated: pick_color_texture_/_view_, pick_normal_texture_/_view_,
pick_depth_texture_/_view_, pick_staging_buffer_, pick_normal_staging_buffer_,
pick_w_/_h_, box_pick_staging_buffer_/_capacity_. The pick_pipeline_
itself was already aliased.
The pick path no longer reaches into VW for any GPU state, so the
render() / shutdown() callers become core_.X() forwards and the pick
infrastructure can be exercised by the future web build without going
through Qt.
buildEdgePipeline, encodeEdgePass, releaseEdgeResources + the EDGE_WGSL
shader source all move to ViewportCore. The edge_bind_group_ + the
edges_enabled_ flag come along too (the latter aliased on VW so the
edge-toggle keybind keeps compiling).
The pass binds the now-core-side depth_view_ directly, so there's no
remaining cross-side state dependency for edge rendering. render()
still calls core_.encodeEdgePass(enc, surface_view) — once render()
itself moves, the call collapses to a sibling method invocation.
The whole HiZ occlusion-cull pipeline (resolve pass, ping-pong async
readback, CPU mip pyramid, per-instance AABB lookup, WGPU_HIZ_TRACE
diagnostic) moves to ViewportCore. The main render-pass depth
attachment and MSAA color attachment come along too — they're shared
between render() (still VW) and the HiZ resolve pass (now core).
Methods migrated: buildHizPipeline, ensureHizTextures,
releaseHizResources, encodeHizResolve, startHizMap, drainHizReadbacks,
aabbOccludedByHiz, ensureDepthTexture, releaseDepthTexture,
ensureMsaaColorTexture, releaseMsaaColorTexture. HIZ_WGSL moves with
them into ViewportCore.cpp's anon namespace.
State migrated: hiz_enabled_, hiz_valid_, hiz_vp_, hiz_pyramid_,
hiz_mip_offset_/_w_/_h_, hiz_reject_count_, hiz_trace_budget_,
hiz_uniform_buffer_, hiz_bind_group_, hiz_resolve_texture_/_view_/_w_/_h_,
hiz_padded_bpr_, hiz_staging_buffers_[2], hiz_slot_vp_[2],
hiz_slot_state_[2], hiz_write_idx_, depth_texture_/_view_/_w_/_h_,
msaa_color_texture_/_view_/_w_/_h_, plus the HizSlotState enum +
HIZ_SLOTS + HIZ_BASE_W constants. ViewportWindow keeps reference
aliases on every field VW.cpp still touches so the render path
compiles unchanged.
The HizOccludedFn shim in render() now wraps core_.aabbOccludedByHiz
directly. Once the render path itself moves into core, that shim
disappears and cull can call aabbOccludedByHiz as a sibling method.
applyCachedModel, uploadMeshChunk, uploadInstanceChunk, finalizeModel
all live in ViewportCore now. The bonsai-facing public entry points on
ViewportWindow are one-line forwarders that keep
SceneLoader → ViewportWindow* binding intact.
State + helpers that came along:
- pending_direct_loads_ (the SidecarData staging map keyed by model_id)
- initial_view_applied_ (auto-viewAll suppression; aliased on VW so
setCamera can still flip it)
- getOrCreateDirectStaging + createBufferWithData (anon namespace
helpers on the core side)
The Qt-bound isExposed() / requestUpdate() pair on the
applyCachedModel tail becomes host_->requestFrame() — the
QtViewportHost forwards to requestUpdate(); a WebViewportHost will
forward to requestAnimationFrame.
The sidecar load path is now fully core-side. ViewportWindow no
longer owns any of the model-creation machinery; everything from
"here's a parsed sidecar" to "fully-built models_gpu_ entry with
empty pool slices waiting on streaming" runs through ViewportCore.
CPU cull (frustum + contribution + LOD + opaque/transparent partition)
and its companion GPU-upload step now live in ViewportCore. The HiZ
occlusion test stays in VW — the pyramid + async readback machinery
hasn't migrated yet — and is plumbed through a
ViewportCore::HizOccludedFn callback the render path binds when HiZ
is enabled-and-fresh. Null callback means "no occlusion test", which
keeps the cull path host-agnostic.
extractFrustumPlanes + aabbInFrustum moved up into CameraMath.h so
both VW's render() (where the planes are extracted) and core's cull
(where they're tested) can share without one #including the other.
LOD-debug counters (lod1_dbg_count_, lod0_dbg_eligible_count_,
lod0_dbg_no_lod1_count_, lod1_dbg_tris_saved_) moved to core too —
they're written by cull and read/reset by VW's still-here per-frame
[frame] heartbeat through reference aliases.
The per-frame streaming residency driver — LRU/priority eviction,
worker-result drain, candidate selection, click-and-track diagnostic,
sync-fallback for screenshot capture — now lives in ViewportCore.
ViewportWindow::driveStreamingLoads is a one-line forwarder.
Streaming-related state moves to core with reference aliases on VW:
streaming_{loads,more_pending,candidates,evictions_{lru,pri},drained,
blocked_oom}_this_frame_, streaming_debug_, tracked_{object_id,
chunk_mid,chunk_idx,was_resident}_, and pending_screenshot_path_. The
pick handler and bench-warm gate (still VW) read/write through the
aliases unchanged.
Qt-isms in the body were replaced en route:
- QFileInfo(...).completeBaseName() → std::filesystem::path::stem()
- requestUpdate() → host_->requestFrame()
- QString::number(x, 'f', N) in numeric logs → raw double / int (we lose
fixed-precision in a couple of diag lines; acceptable tradeoff).
host_->requestFrame() means the streaming loop is now host-agnostic:
the WebViewportHost will provide its own requestAnimationFrame
equivalent when it lands.
The chunk-state machine that mediates between the streaming pool and the
per-chunk WGPU bind groups now lives in ViewportCore. ViewportWindow's
remaining streaming code (driveStreamingLoads, finalizeModel) calls
through to core_.applyStreamedChunk / core_.unloadChunk /
core_.loadChunkBytesAndUploadGpu, and the chunk request builder is a
static helper on ViewportCore so VW's still-here driveStreamingLoads can
enqueue requests against streaming_thread_ without reimplementing it.
streaming_frame_idx_ moved to core (alongside the residency clock),
aliased on VW so the inline streaming logic stays compiling. The
mesh-volume side effect inside applyStreamedChunk now fires a
std::function<void()> callback (core_.on_volume_dirty_) instead of
reaching into ViewportWindow::updateVolumeReadout — VW wires the
callback in its ctor, non-Qt hosts leave it null and pay nothing.
computeMeshLocalVolumeQuantised moved to ViewportCore.cpp's anonymous
namespace; it was only called by applyStreamedChunk.
Per-frame uniform packing now lives in ViewportCore::updateFrameUniforms,
which reads the camera (via the already-migrated buildViewProj), the
section_planes_ vector, and the xray_alpha_cap_ scalar — all of which
have moved into ViewportCore alongside frame_uniform_buffer_.
ViewportWindow keeps reference-aliases on section_planes_ and
xray_alpha_cap_ so the section-tool and X-ray toggle (still Qt-input-
bound, still living in VW) keep compiling unchanged. The render-path
caller in VW::render now does core_.updateFrameUniforms().
Extracted SectionPlane into its own Qt-free header (SectionPlane.h)
so ViewportCore doesn't have to include OverlayRenderer.h's QString /
QHash. OverlayRenderer.h re-exports it.
The instance/adapter/device/queue/pool/surface-format wgpu lifecycle now
lives in ViewportCore — including the OOM-scoped pool size probe and
the worker-thread startup. ViewportWindow::initWgpu becomes a Qt shell
that handles env-var tuning + nav-button preset wiring, then delegates
to core_.initWgpu(); the VW-only pipeline builders (HiZ, edge, overlays,
pick) still run after. ViewportWindow::shutdown drops the VW-only
resources (depth, msaa, hiz, edge, overlays, pick) and lets
core_.shutdown() release the shared wgpu handles it now owns.
The wgpu-native log callback (wgpuSetLogCallback / WGPULogLevel) is
gated on !__EMSCRIPTEN__: it's not part of the W3C spec header, and
the emdawnwebgpu port doesn't ship wgpu.h — validation errors there
land in the browser console regardless.
Drive-by: update test_federation to compare HomeView::target as
Eigen::Vector3f (left stale by #79 when QVector3D was retired).
Move the main render pipeline construction + the selection flags
buffer/bind group lifecycle. Both buildPipelines and the selection
flags methods produce/consume state ViewportCore already owns
(main_pipeline_, frame_bgl_, etc.) plus a handful of "frame
infrastructure" fields this commit also brings across.
State moved (7 fields):
WGPUBuffer frame_uniform_buffer_
WGPUBindGroup frame_bind_group_
WGPUBuffer selection_flags_buffer_
uint32_t selection_flags_capacity_
std::vector<u32> selection_flags_scratch_
SelectionState selection_
VisibilityState visibility_
Methods moved:
buildPipelines (~150 lines + 320-line MAIN_WGSL string)
ensureSelectionFlagsBuffer (~60 lines)
uploadSelectionFlagsIfDirty (~10 lines)
Plus the MAIN_WGSL constant + the svFromCStr helper into
ViewportCore.cpp's anonymous namespace. ViewportWindow.cpp keeps its
own svFromCStr copy (still used by 50+ label fields in the not-yet-
moved pipeline builders + render encoders).
Shared constants extracted to ViewportCore.h:
kMaxSectionPlanes (was OverlayRenderer::kMaxSectionPlanes — assert
in VW.cpp keeps them in sync)
kViewportSampleCount (was SAMPLE_COUNT in VW; VW keeps a static
constexpr alias for the existing callsites)
struct FrameUniforms (canonical layout for the per-frame UBO,
consumed by both core's buildPipelines and
VW's still-in-flight updateFrameUniforms)
Builds: desktop / bonsai / web all green. Tests 100/100.
Tiny followup to #84-i — move the const-lookup volume helpers used by
bonsai's measurement HUD:
double volumeOfObjects(const std::vector<uint32_t>&) const
vector<pair<uint32_t, double>> volumesPerObject(
const std::vector<uint32_t>&) const
The det3OfPlacement static helper moves with them into ViewportCore.cpp's
anonymous namespace (the original kept its mirror in
ViewportWindow.cpp; ViewportWindow's own internal callers are gone now
since these methods moved).
Pure read of models_gpu_ + mesh_local_volumes — all in core already.
Trivial transplant.
