Hartmut b795f0e6d6 refactor: rebrand project to HartOMat 2026-04-06 12:45:47 +02:00
Hartmut 02669c395c fix: cinematic camera accounts for output aspect ratio 
For 16:9 (1280x720), vertical FOV is narrower than horizontal —
products could be clipped top/bottom. Now applies an aspect ratio
correction factor to camera distance: wider formats push camera
further back proportionally.

Still render (_blender_camera.py) already handled this via
min(fov_h, fov_v); cinematic now has equivalent correction.

Hartmut 81eb1f9eae fix: cinematic camera distances — no clipping, full product always visible 
Redesigned all 3 segments to keep distance > 3× bsphere_radius:
- Segment 1: 3.5× → 3.0× (establishing orbit, 50mm)
- Segment 2: 3.0× → 3.2× (low angle sweep, 50→65mm)
- Segment 3: 3.2× → 4.0× (crane up, 50→40mm)

Removed: detail closeup (was 1.5-1.8×, caused object clipping),
telephoto 85mm (caused extreme close framing), DOF (not needed at safe distance)

Hartmut 3a815a85c5 fix: Blender 5.0 Action.fcurves API change — safe LINEAR keyframe setting 
Blender 5.0 renamed Action.fcurves. Now tries fcurves first, falls
back to channels, and wraps in try/except so the render proceeds
even if LINEAR interpolation can't be set.

Hartmut 458c6cd813 refactor: cinematic render — linear keyframes, 3 segments, 250 frames, white bg 
Changes per user feedback:
- Keyframe interpolation: BEZIER → LINEAR (all fcurves set to LINEAR)
- Removed segment 4 (closeup) — now 3 segments only
- Frame count: 480 → 250 (10 seconds at 25fps)
- FPS: 24 → 25
- Easing removed — pure linear interpolation between segment params
- White background by default (World node Color = white)
- Transparent bg still available as override

Hartmut 75ad397c09 fix: unbuffered stdout for live cinematic frame progress 
Two fixes for frame progress not appearing in frontend:
1. Added flush=True to all print() calls in cinematic_render.py
2. Set PYTHONUNBUFFERED=1 in subprocess environment

Without these, Python buffers stdout inside Blender, so all frame
progress lines arrive in a batch after the process exits instead
of streaming line-by-line during rendering.

Hartmut f22b963be9 feat: cinematic highlight render — 20s procedural camera animation 
New render type: 4-segment cinematic camera animation (480 frames @ 24fps)
for professional product highlight videos.

Camera sequence:
1. Establishing (5s): slow 45° orbit + push-in, 50mm lens
2. Detail sweep (5s): low-angle close arc, 85mm telephoto, shallow DOF
3. Crane up (5s): rising 30°→60°, 35mm wide reveal, pull-back
4. Hero close (5s): push-in to beauty angle, 65mm, smooth ease-out

Technical:
- cinematic_render.py: procedural camera from bounding sphere, cubic easing,
  per-frame keyframes (location, rotation, focal length, DOF)
- render_cinematic_to_file(): service function (same pattern as turntable)
- Pipeline routing: render_settings.cinematic flag → cinematic path
- Depth of field enabled (f-stop scales with product size)
- use_persistent_data for BVH caching between frames
- Same material/template/USD pipeline as turntable
