SteerScene on other backbones: best outputs

SteerScene training-free guidance applied to PhyScene (CVPR'24) and InstructScene (ICLR'24) without retraining. Box sizes are frozen during guidance (only positions and rotations are steered). Weights were tuned on held-out data (PhyScene seed 2028; InstructScene val) and the outputs here are on the reported sets.

physcene/ (living room, seed 2027, 1024 scenes)

Current pick: steerscene_p_w3_r10/ (section below). steerscene_old_c100_r1/ is the earlier pick (collision 100, room 1), superseded.

• steerscene_old_c100_r1/: collision_weight 100, room_weight 1. Steering starts at ratio 0.9 with interval 1, strength 20 and a per-object gradient clip of 10.1; guide_sizes=False.
  • result.json: raw layouts. result_resolved.json: layouts after the shared collision resolver (max_iter 500, push_eps 0.02).
  • *.floor.json: floor polygons.
  • *.eval_*.log: PhyScene official metrics.
  • glb_first100[_resolved]/: textured GLB plus per-object JSON for the first 100 scenes.
• no_guidance/: the PhyScene checkpoint with no guidance (same seed), layouts and logs only.

	ColObj (mesh)	after resolver
no guidance	0.217	0.107
SteerScene	0.184	0.106

instructscene/{bedroom,diningroom,livingroom}/tuned (test split)

• Config: {"relation_start_ratio": 0.9, "room_weight": 1.0, "collision_weight": 30.0}, with collision, relation and room losses on.
• result.json: layouts, edges, predicates and class names.
• eval_cfg1.0.txt: InstructScene official relation error.
• glb/: one GLB per scene.

Cells are ColObj / OOB per scene / relation error:

physcene/steerscene_p_w3_r10 (current PhyScene pick, 2026-10-21)

Config p_w3_r10, tuned on seed 2028:

• collision_weight 100;
• room_weight 10 with room_polygon=true: the room term follows the real floor polygon;
• walkable_weight 3: the work-37 walkable term (center penalty + edge Gaussian);
• sizes frozen.

Reported on seed 2027, 1024 scenes. Files are laid out as for steerscene_old_c100_r1; metrics_test.txt holds every metric for this run and the baselines.
