Generated from: a scene from a small video game about: Create a high-fidelity 3D physics sandbox game focused on precise laser optics and light interaction. Core Requirements (non-negotiable): 1. Engine & Rendering - Built in a modern real-time 3D engine (Unity / Godot 4 / Unreal) with physically-based rendering. - Perfect deterministic physics at fixed timestep (60 or 120 Hz). - Laser is a true ray-traced or high-precision multi-bounce beam (not approximate particles). - Accurate refraction, reflection, absorption, dispersion, and polarization simulation. - Real-time glass caustics, lens distortion, and beam attenuation. 2. Laser System - Player-controlled precision laser emitter with adjustable wavelength (visible spectrum), power, and divergence. - Instantaneous multi-bounce raycasting with exact hit detection (sub-millimeter precision). - Supports splitting, combining, focusing, and color mixing of beams. - Visual beam is razor-sharp with realistic intensity falloff and bloom only where optically correct. 3. Placeable Objects (full menu system) - Large categorized inventory menu (scrollable, searchable, with previews and stats): - Glasses & Lenses: convex, concave, cylindrical, Fresnel, prisms (various angles), dichroic mirrors, beam splitters, polarizers, filters (RGB + IR/UV). - Mirrors: plane, spherical, parabolic, adjustable-angle, motorized. - Diffusers, beam dumps, irises, shutters, diffraction gratings. - Interactive objects: movable platforms, rotating mounts, gravity-affected free bodies, triggers, sensors, detectors. - Advanced: fiber optics, waveguides, holographic plates, adaptive optics. - Every object has accurate physical properties (index of refraction, reflectivity, absorption coefficients, mass, friction, restitution). - Drag-and-drop or precise placement mode (snap-to-grid + free-form with numerical input for position/rotation). - Objects can be locked, grouped, duplicated, deleted, and have material presets. 4. Physics & Interaction - Perfect rigid-body physics for all free objects. - Laser can push light objects via radiation pressure when power is high. - Collision detection between physical objects and beams is exact. - Support for stacking, pivoting, and complex kinematic assemblies. - Save/load full scenes with all object states and laser settings. 5. Interface & Usability - Clean, professional UI: - Left or right-side object library with categories and search. - Top toolbar for laser controls (wavelength slider, power, mode). - Bottom status bar showing beam path length, intensity at detectors, active bounces. - Gizmo-based transform tools (translate/rotate/scale) with numerical precision input. - Measurement tools (distance, angle, intensity probes). - First-person or free-fly camera with smooth controls + orbit mode around selected objects. - Undo/redo stack and quick-save slots. 6. Quality Bar - Zero visual artifacts on beams or glass. - Sub-pixel precise placement and rotation. - Fully deterministic simulation (same scene always produces identical results). - High performance even with dozens of simultaneous multi-bounce lasers and complex glass setups. - Beautiful, minimal cyber-lab aesthetic (dark environment, emissive UI, clean materials). Output a complete, production-ready technical design + implementation plan (or full working prototype code if the target engine allows) that delivers the above with zero compromise on physics accuracy or laser precision., as an in-game screenshot in flat colour 2D shapes with a bright limited palette. Palette: sky blue #8ecae6, grass #3a7d44, player sunflower #ffb703, threat red #d62828, accent white #fdfcdc. Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one. Keep the pictures honest: they promise what a small first version of this game, made in a game engine in a few days, can look like. Simple readable shapes, clear silhouettes, few flat materials, the in-game camera view. Never film stills, photoreal renders, AAA key art, detailed textures, cinematic lighting, or anything that looks like a big-studio game. No text, UI, HUD, logos or editor screens inside any image.
