status: done_current_scope
|
|
task: SceneIR adapter
|
|
|
|
ViewportRenderer now tags imported meshes and lights with
|
|
`userData.blenderId`, `userData.sceneNodeId` and `userData.revision`, keeps a
|
|
Blender-ID object index, and exposes `applyDelta()`. Pure node visibility and
|
|
transform updates mutate the existing Three object; node lifecycle changes
|
|
fall back to a validated snapshot rebuild so geometry/material ownership stays
|
|
correct.
|
|
|
|
The adapter now performs mesh raycast selection and applies multi-selection
|
|
highlights, consumes binary WBG1 mesh resources, and installs validated LOD
|
|
levels with hysteresis. Resource-aware SceneDelta entries trigger a validated
|
|
resource rebuild while node-only deltas update existing Three objects.
|
|
|
|
The Worker keeps the previous geometry generation and emits byte-range patches
|
|
or affected-mesh replacements. Objects sharing one Blender Mesh datablock are
|
|
coalesced into a raycastable `InstancedMesh` with per-instance transform and
|
|
selection. A capability-gated OffscreenCanvas Worker owns WebGL when requested;
|
|
browsers without that capability retain the same main-thread renderer.
