|---|---|---|---|---|---|---|---|
optics_001 | mirror_reflection | Single vehicle, direct sunlight from one side, large mirror positioned to reflect sunlight onto the shaded side. | Reflected sunlight should partially illuminate the shaded side and soften existing shadows. | Shaded side remains dark; mirror not treated as secondary light source. | Model renders mirror visually but ignores reflected light contribution to global illumination. | reference_files/optics_001.png | reflection,secondary_light,global_illumination,shadow_softening,mirror |
optics_002 | reflected_light_behavior | Minimal scene: one object, one mirror, one sun, no additional elements. | Reflected light should be diffuse and reduce shadow contrast on the opposite side. | Reflected light appears beam-like or overly sharp. | Model confuses diffuse reflected illumination with direct light rays. | reference_files/optics_002.png | diffuse_light,specular_error,indirect_light,beam_artifact |
optics_003 | shadow_interaction | Object partially illuminated by reflected sunlight while still casting shadows. | Shadows should soften or partially disappear under indirect illumination. | Shadows remain hard or disappear in physically incorrect regions. | Model fails to determine how indirect light modifies existing shadows. | reference_files/optics_003.png | shadow_logic,indirect_light,physical_inconsistency |
optics_004 | mirror_geometry | Vehicle reflected in a planar mirror visible to the camera. | Mirror should show correct geometry, perspective, and shadow orientation. | Reflection shows duplicated or incorrect geometry and perspective. | Model copies object appearance instead of computing true geometric reflection. | reference_files/optics_004.png | mirror_geometry,perspective_error,reflection_duplication |
optics_005 | real_world_comparison | Real-world test: scale model, sunlight, real mirror used to redirect light. | Reflected sunlight partially illuminates shaded regions depending on angle. | AI-generated scene fails to reproduce subtle angle-dependent illumination. | Physical experiment confirms effect exists; model fails to reproduce it reliably. | reference_files/optics_005.png | real_world_validation,angle_dependency,model_gap |
Geometric Optics – Physical Consistency Evaluation Dataset
This dataset contains visual failure cases in geometric optics for multimodal image generation models.
Scope
The dataset focuses on physical and geometric inconsistencies related to:
- mirror reflections (law of reflection)
- refraction and dispersion in prisms
- light ray direction consistency
- shadow direction vs light source
- camera–object–light spatial coherence
Motivation
Current image generation models often produce visually plausible results that violate basic physical laws of optics. These failures persist even with explicit textual constraints.
This dataset is designed for evaluation (not training) of multimodal reasoning and physical consistency.
Failure Categories
- reflection_angle_violation
- refraction_direction_error
- dispersion_order_incorrect
- shadow_light_mismatch
- impossible_light_path
Intended Use
- Model evaluation (GDPval / Evals)
- Multimodal reasoning research
- Physics-aware image generation analysis
