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.
Builds: desktop / bonsai / web all green. Tests 100/100.
Move the cluster of camera-state mutators + per-object AABB helpers
now that the camera fields all live in ViewportCore. CameraState
struct is canonical in core; ViewportWindow keeps a `using` alias
so bonsai's HomeView round-trip (Commands.cpp setHome / restoreHome)
compiles unchanged.
Moved:
void viewAll()
void setCamera(...) — pitch + distance clamping included
void setStandardView(yaw, pitch) — bypasses clamp for ±90°
void toggleProjection()
std::string cameraString() const
CameraState cameraState() const
void frameAabb(mn, mx, padding)
bool computeObjectAabb(id, float[3], float[3]) const
bool computeObjectAabb(id, Eigen::Vector3f&, Eigen::Vector3f&) const
ViewportWindow keeps thin forwarders for the public ones (bonsai
calls them). setCamera additionally flips initial_view_applied_
on the VW side — the auto-viewAll suppression flag isn't in core
yet because the trigger for auto-viewAll lives in the still-in-VW
applyCachedModel path.
The isExposed()+requestUpdate() Qt pattern inside the moved bodies
becomes host_->requestFrame(); two viewAll/toggleProjection diagnostic
prints become fprintf since Log::info() doesn't reach into core.cpp
through the Qt logging surface.
Builds: desktop / bonsai / web all green. Tests 100/100.
Move the three camera-math methods that compute view/projection
matrices, scene bounds, and per-chunk screen footprint for the
streaming priority signal:
void buildViewProj(Eigen::Matrix4f&, Eigen::Matrix4f&) const
bool computeSceneAabb(float[3], float[3]) const
float chunkScreenAreaPx(const ModelGpuData::Chunk&,
const Eigen::Matrix4f&) const
Plus the orbitEye helper (anonymous namespace in ViewportCore.cpp;
the qDegreesToRadians dep got swapped for an inline M_PI/180 constant).
ViewportWindow.cpp's 9 internal callers (cull, streaming, pick,
render, debug) updated to use core_.buildViewProj() etc. The
buildViewProj forwarder stays out of ViewportWindow.h since no
external caller needs it — bonsai/minimal both go through
public API methods like viewAll which still wrap core_ access
on the VW side.
Builds: desktop / bonsai / web all green. Tests 100/100.
Move the camera/projection/clear-color fields that buildViewProj,
updateFrameUniforms, the cull screen-area projector, and the bonsai-
side cameraState/setCamera/viewAll surface depend on. Same alias
pattern; no method bodies move in this commit — the next one moves
the camera math methods now that all their state is in core.
State moved (12 fields):
int configured_w_, configured_h_
float camera_target_[3], camera_distance_
float camera_yaw_deg_, camera_pitch_deg_, camera_fov_y_deg_
float camera_near_, camera_far_
bool projection_ortho_
Eigen::Vector4f background_color_
ViewportWindow keeps reference aliases for each (including a proper
`float (&camera_target_)[3]` reference-to-array binding) so the
~150 call sites that touch camera state stay unchanged. Aliases
collapse when their owning methods migrate.
Builds: desktop / bonsai / web all green. Tests 100/100.
Move the eight scene-mutation methods that drive bonsai's load/unload
and georeference setters, plus the per-model GPU teardown helper.
All are mechanical transplants — no logic change — so behaviour stays
identical; only the owner has changed.
Methods moved (ViewportWindow public-API methods stay as forwarders
to keep the bonsai-side callers compiling):
removeModel / resetScene / hideModel / showModel
setFederatedFalseOrigin
setModelCoordinateOperation
setModelTransformation
recomposeAndUploadModel
State moved:
bool wgpu_initialized_ (storage → core_, alias kept in VW for
the initWgpu call site that still flips
it; goes when initWgpu moves)
Free function moved:
releaseWgpuModelGpuData(ModelGpuData&, BufferPool&) → ViewportCore.cpp
(must live in IfcViewerCore now that ViewportCore.cpp's
removeModel / resetScene call it; ViewportWindow.cpp's remaining
two call sites continue to resolve through ModelGpuData.h's
declaration — same linker view, different definition TU)
The `if (isExposed()) requestUpdate()` Qt pattern inside the moved
bodies became `host_->requestFrame()` since ViewportCore can't see
QWindow; the desktop ViewportHost override at the bottom of
ViewportWindow.cpp continues to translate that into requestUpdate().
Builds: desktop / bonsai / web all green. Tests 100/100.
Move two pure-read methods (no GPU touch, no Qt) that the bonsai
measurement / federation-origin paths use:
bool findInstance(uint32_t, InstanceLookup&) const
bool firstGeometryPointWorldM(uint32_t, Vector3d&) const
ViewportWindow keeps both public-API method names — they now forward
to core_ for the implementation so existing callers in
bonsaiviewer/Measurement.cpp + Federation hooks don't have to change.
The InstanceLookup type also stays a `using` alias in ViewportWindow
(was added in #74).
Both methods were already de-Qt'd (`findInstance` delegates to
InstanceCompose; `firstGeometryPointWorldM` is pure Eigen). The move
is a straight transplant — no behaviour change.
Builds: desktop / bonsai / web all green. Tests 100/100.
First method-body migration. composeInstanceFromPlacement composes the
federated-false-origin × model-transformation × coordinate-operation ×
placement chain and re-derives the world AABB; it's a small,
self-contained method that only reads scene state and one matrix.
Moved:
Eigen::Matrix4d federated_false_origin_meters_ (storage → core_)
void composeInstanceFromPlacement(InstanceCpu&, ...) (body → core_)
ViewportWindow keeps:
- alias reference to federated_false_origin_meters_ (existing
setFederatedFalseOrigin call site still writes through it)
- no method declaration — internal callers route through core_
Internal caller (recomposeAndUploadModel) now invokes
core_.composeInstanceFromPlacement; once recomposeAndUploadModel
itself moves into ViewportCore the call shortens back.
Pattern for the rest of #84: state moves, then method body moves,
then internal callers update. Each commit leaves desktop / bonsai /
web green and tests 100/100. This is one of many such steps.
Move the five scene-state fields that drive per-model GPU upload + the
streaming residency loop into ViewportCore:
BufferPool pool_ — vertex+index sub-allocator
StreamingThread streaming_thread_ — background chunk reader
std::unordered_map<uint32_t, ModelGpuData> models_gpu_
— per-model state
uint32_t next_model_id_ — model-id allocator
uint32_t next_object_id_ — globally-unique object-id allocator
ViewportCore.h gains transitive includes for BufferPool / StreamingThread
/ ModelGpuData; ViewportWindow keeps the same names as reference aliases
so existing method bodies that touch them don't have to change.
Same risk profile as #84-a and #84-b: the storage moved but the values
are still set and consumed by the same code paths, so behaviour stays
identical.
Builds: desktop / bonsai / web all green. Tests 100/100.
Move the 15 pipeline + bind-group-layout + shader-module handles
that buildPipelines / buildEdgePipeline / buildPickPipeline write to.
Same pattern as #84-a: storage lives in ViewportCore, ViewportWindow
keeps reference aliases so existing builder-method bodies don't
have to acquire a `core_.` prefix at every touch point.
Moved fields:
Main render group:
main_shader_module_, frame_bgl_ (group 0), model_bgl_ (group 1),
pipeline_layout_, main_pipeline_, main_pipeline_transparent_
HiZ occlusion-cull group:
hiz_shader_module_, hiz_bgl_, hiz_pipeline_layout_, hiz_pipeline_
Edge silhouette group:
edge_shader_module_, edge_bgl_, edge_pipeline_layout_, edge_pipeline_
Pick pass:
pick_pipeline_ (reuses pipeline_layout_ — same set of bindings)
ViewportWindow's constructor binds 16 new alias references after
the 7 lifecycle ones from #84-a; member-init order matches
declaration order so core_ is constructed before any alias binds.
Builds: desktop / bonsai / web all green. Tests 100/100.
First chunk of the #84 ViewportCore extraction. The seven wgpu lifecycle
handles (instance, adapter, device, queue, surface, surface_format,
surface_configured) now live as ViewportCore members; ViewportWindow
keeps reference aliases pointing at ViewportCore's storage so its
existing render-method bodies don't need a `core_.` prefix added at
every call site — 230+ touches deferred until each method moves
across.
Member init order in ViewportWindow's constructor:
core_(this) → constructs ViewportCore with host_=this
instance_(core_.instance_) → binds the alias to core_'s field
… same for adapter/device/queue/surface/…
Friend declaration on ViewportCore::ViewportWindow lets the references
bind to its private fields. The friend bond shrinks each commit as
render methods (and their `device_` / `queue_` references) migrate into
ViewportCore proper; the goal state is no friend and no aliases.
Next #84 chunks (separate commits) move pipelines, models_gpu_, pool_,
streaming_thread_, then the render/cull/encode methods. Each leaves
the desktop build green.
Builds: desktop / bonsai / web all green. Tests 100/100.
Define the boundary the Path-A web-bring-up refactor will move things
across:
- ViewportHost.h is the embedder interface — surface creation,
framebuffer geometry, frame scheduling, quit, and notification
callbacks (onObjectPicked, onToolModeChanged, …). Desktop hosts
forward notifications to Q_SIGNALS; the future web host pushes
them to JS callbacks.
- ViewportCore.{h,cpp} is the platform-agnostic render-core target.
Empty today — the body fills in across the #78-#86 sequence as
each Qt subsystem (matrices, vectors, strings, timers, render
path, input) gets de-Qt'd and moved over.
- ViewportWindow now multiply-inherits ViewportHost alongside QWindow
and implements the host overrides as thin forwarders: createSurface
returns the cached surface_, requestFrame -> requestUpdate, quit ->
QCoreApplication::quit, onObjectPicked -> emit objectPicked.
Renamed the DPR accessor `dpr()` (vs `devicePixelRatio`) to avoid
the inherited-virtual clash with QWindow's qreal-returning version.
No method movement yet — this is purely the architectural scaffold so
subsequent commits have a destination.
