M1 — dead code removed: - Delete blender-renderer/ and threejs-renderer/ source files - Remove PIL/Pillow fallback block from step_processor.py (_generate_thumbnail_placeholder, _finalise_image JPG path) - Remove stl_quality param from render_blender.py, render_still_task, render_turntable_task (was always "low"; hardcode deflection values) - render_turntable_task now reads scene_linear/angular_deflection from system_settings (consistent with export_glb.py pipeline) M3 — blender_render.py split from 263 → 68 lines: - _blender_args.py: parse_args() — all 25 positional + named args - _blender_scene_setup.py: setup_scene() — MODE A/B including USD import - _blender_render_config.py: configure_and_render() — engine + output Post-review fixes: - _db_engine.dispose() after settings read in render_turntable_task - _finalise_image() fmt param removed (always PNG; PIL never installed) - _blender_import.py committed together with new submodules to satisfy import_usd_file dependency Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

|
Blender Python script for rendering a GLB file to PNG.
|
|
Targets Blender 5.0+ (EEVEE / Cycles).
|
|
|
|
Called by Blender:
|
|
blender --background --python blender_render.py -- \
|
|
<glb_path> <output_path> <width> <height> [engine] [samples]
|
|
|
|
engine: "cycles" (default) | "eevee"
|
|
|
|
Features:
|
|
- OCC-generated GLB: one mesh per STEP part, already in metres.
|
|
- Bounding-box-aware camera: object fills ~85 % of the frame.
|
|
- Isometric-style angle (elevation 28°, azimuth 40°).
|
|
- Dynamic clip planes.
|
|
- Standard (non-Filmic) colour management → no grey tint.
