Interactive 3D Experiment Platform Development

This is not a single experiment project. The goal is to build a reusable, scalable system where new experiments can be created easily without changing core code. All 3D assets (.glb models) will be provided by me. The freelancer will focus only on coding, simulation logic, and system design. The platform must allow an admin to create experiments using an admin panel, and student results must depend entirely on how the student performs the experiment, not on pre-scripted animations. Core Requirements: A reusable 3D experiment engine using [login to view URL] (ES Modules). Experiments must be driven by JSON configuration, not hard-coded logic. Admin should be able to create, edit, delete, and preview experiments without developer help. Student outcomes must depend on correct procedure, measurements, and actions. The system must be optimized to work on low-end devices commonly used in India. Technology Stack (Mandatory): Frontend / Simulation: [login to view URL] (ES modules) GLTFLoader Custom interaction controllers (drag, tilt, rotate, pour, etc.) HTML, CSS, Vanilla JavaScript (minimal framework if needed) Backend / Admin Panel: PHP (Laravel preferred, plain PHP acceptable) JSON-based experiment definitions MySQL or SQLite Assets: All .glb models will be provided by me Animations such as heating, pouring, smoke, boiling to be handled in [login to view URL] Key Features to Implement: 3D Simulation Engine: Drag objects independently Tilt objects (for pouring, rotation) Heating simulation (temperature-based) Mixing and stirring Measurements (volume, mass, time) Collision handling and surface restriction (objects should stay on table) Experiment Logic System: Initial state definition Rule-based simulation logic (conditions and effects) Step-by-step procedure validation Measurement tolerance handling Scoring and feedback system Admin Panel: Create new experiments Edit existing experiments Delete experiments Add, edit, delete experiment steps Define simulation rules and scoring Select or assign provided .glb models Download experiment JSON View / preview experiment in 3D Student Evaluation: Results depend on how the student performs the experiment Partial scoring supported Feedback explaining mistakes (not just right or wrong) Examples of Experiments the System Must Support: Physics: Ohm’s Law Simple Pendulum Projectile Motion Chemistry: Heating and boiling Titration Solution concentration Biology: Microscope focusing Cell observation Slide identification Expected Folder Structure: lab/ admin/ js/ engine/ controllers/ experiments/ assets/ models/ See demo i built: [login to view URL] [login to view URL]
