We are looking for an experienced Three.js developer to build a proof-of-concept (POC) prototype. The goal is to demonstrate a visual effect where 3D Model A is rendered as a particle cloud, and on scroll interaction, those particles transition and reassemble into 3D Model B.
Objectives
- Load two provided 3D models (likely STL/OBJ).
- Convert Model A into a particle cloud representation (basic geometric shapes OR a cloud of obj models).
- On user scroll, animate the particles transitioning to form Model B.
- Ensure the effect is smooth, performant, and visually impressive.
- The code should be clean, modular, and easy for our internal dev team to build on.
Example of what we have in mind: https://dala.craftedbygc.com/ https://discourse.threejs.org/t/animate-particles/56095
Key Requirements
- Strong experience with Three.js, especially points/particles, shaders, and custom animations.
- Ability to handle converting 3D geometry into particle positions.
- Implement scroll interaction (e.g., via GSAP ScrollTrigger, locomotive scroll, or vanilla).
- Handle transitions between two distinct sets of particle coordinates.
- Provide fallback or graceful degradation if performance is limited.
- Must run smoothly on modern desktop browsers (Chrome/Safari/Firefox). Mobile optimisation is nice-to-have, not required for this POC.
Deliverables
- A standalone web prototype (ideally in React but you can use a framework of your choice)
- Working particle-to-particle transformation between two models.
- Basic styling and camera controls suitable for demonstration.
We will provide
- 3D models
- Any brand visuals if needed for presentation
Timeline
We’d like the prototype within 1–2 weeks from project start.
