Visible CPU surface emission (#1695)
This transient option adds visible emission to the existing opaque CPU consumer. At the recovery handoff the source checkpoint was not compiled or run. Subsequent combined CPU renderer regressions have executed for linear radiance, sidedness, zero identity, reflected hits, target refusal and work/cancellation. Current combined engine/UI/native qualification and project gates remain pending.
The transient render.preflight / render.start raytrace options accept:
{"integrator":"raytrace","raytrace":{"lights":[],"emissions":[{"body_index":0,"body":"Emitter","color":[1,0.5,0.25],"strength":2,"sides":"front"}]}}
Targets match both the original captured mesh index and exact body name. Missing or renamed targets refuse; duplicate body indices refuse. A body term applies uniformly to its triangles, including triangles with face appearance overrides. Face reflectance continues to override body reflectance independently. No face-specific emitter is inferred from a face color or physical material.
Color is linear sRGB in [0,1], strength is finite relative radiance in [0,64].
No calibrated watts or automatic sRGB decoding is implied. front (default) emits
only when the unflipped geometric normal has positive dot product with the outgoing
view direction. both explicitly emits on either side, including tangency. Shading
normals never select an emitting side. Triangle winding defines the front.
Each hit adds color * strength to reflected linear radiance before the existing
single exposure, Reinhard tone map and sRGB encoding. Missing, empty and zero terms
preserve baseline output. Explicit null, unknown fields and unsupported combinations
refuse. The raster default and GPU preview gain no emission capability. Runtime
inputs do not modify design storage, geometry, engineering properties or caches.
Emission does not add a sampled direct-light source for neighboring surfaces. Without optional opaque path lighting, only existing selected specular paths can reach an emitting surface; with other analytic/HDR lighting disabled and no reflected emitter path, nonemitting surfaces remain dark. Explicit path lighting can carry BSDF-sampled diffuse emission, without mesh-emitter next-event sampling. The primary background retains its original display color.
At most 32 emitter slots and 256 bytes per exact body name are admitted, including original capacities. The host Record owns a request-metadata lease in the existing 512 MiB pool independently of PNG retention. Task copies and prepared terms enter the checked combined 384 MiB job limit before reservations. Per-hit binding checks debit cumulative work and observe cancellation; no new scheduler or pool is used.
Tests written cover linear output/exposure, zero PNG equivalence, front/back normals, unlit neighbors, exact target refusal, duplicate/capacity/JSON bounds and metadata accounting. The renderer cases have executed; current combined engine contracts, full CI, wasm and real command/export/native acceptance remain separate gates.
Integration with the current opaque consumer
Each resolved opaque hit adds its emission once, multiplied by the current path throughput. Directional, punctual, rectangular and HDR stages then retain their existing accumulation. Selected reflections can see an emitting surface; no emitter geometry is sampled to illuminate other surfaces. A new bounce resets the bounded emission cursor. Primary AA averages the same complete linear path estimates, and the output transform remains outside those per-hit stages.
The task estimate explicitly adds both task-owned emission metadata copies and the prepared emission vector. The host's existing complete retained-request calculation also includes original emitter/name capacities, under one Record lease. The existing 4096-byte ImageTask layout assertion remains a build gate. The ordinary CPU/AA controls reject an emission option until its visible editor is integrated; programmatic preflight/start accept the same bounded typed request.
The current-consumer port adds written regressions for AA/reflection divisors, combined directional/point/area lighting and emission reached by a reflected ray. The corresponding renderer integration regressions have executed on the combined candidate. This does not qualify a visible emission editor or native acceptance.
