Hartmut	34f89cc225	feat(gpu): GPU health check + RENDER_DEVICE_USED token + strict mode ... - gpu_probe.py: Blender script that probes OPTIX/CUDA/HIP/ONEAPI and exits 1 on no GPU — used at startup + on-demand from Admin UI - blender_render.py, still_render.py, turntable_render.py: emit RENDER_DEVICE_USED: engine=CYCLES device=GPU|CPU compute_type=... after GPU activation; exit 2 when CYCLES_DEVICE=gpu and CPU fallback - render_blender.py: parse RENDER_DEVICE_USED token into render_log (device_used, compute_type, gpu_fallback); handle exit code 2 as explicit GPU strict-mode failure - check_version.py: check_gpu() runs gpu_probe.py at container startup; CYCLES_DEVICE=gpu aborts startup if no GPU found - docker-compose.yml: CYCLES_DEVICE=${CYCLES_DEVICE:-auto} env var - gpu_tasks.py: probe_gpu Celery task on thumbnail_rendering queue; saves result to system_settings.gpu_probe_last_result; beat every 30min - worker.py: POST /probe/gpu (trigger) + GET /probe/gpu/result (last result) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-08 20:57:36 +01:00
Hartmut	9d1a820295	refactor(A2): replace blender-renderer HTTP service with render-worker Celery container ... - Create render-worker/ with Dockerfile (Ubuntu + cadquery + Blender via host mount) - Add render-worker/check_version.py: verifies Blender >= 5.0.1 at startup, Exit 1 on failure - Add render-worker/scripts/: blender_render.py, still_render.py, turntable_render.py - Create backend/app/services/render_blender.py: direct subprocess rendering - convert_step_to_stl() and export_per_part_stls() using cadquery - render_still(): STEP → STL → PNG via Blender subprocess - is_blender_available(): detects BLENDER_BIN env for render-worker context - Create backend/app/domains/rendering/tasks.py: render_still_task + render_turntable_task - Update step_processor.py: use subprocess path when BLENDER_BIN env is set (render-worker) - Update step_tasks.py: generate_stl_cache uses direct cadquery instead of HTTP - Remove blender-renderer and threejs-renderer from docker-compose.yml - Replace worker-thumbnail with render-worker (Ubuntu + cadquery + Blender mount) - Remove Docker SDK from backend Dockerfile (was only for flamenco scaling) - Update .env.example: BLENDER_VERSION=5.0.1 documented - Update celery_app.py: include domains.rendering.tasks in autodiscover Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-06 15:48:46 +01:00
