Built with Spline
Optimized Spline 3D Smart City for Website

Optimized Spline 3D Smart City for an Interactive Website
Project Overview
This project focused on creating a high-performance Spline 3D smart city environment tailored specifically for a website landing page. The priority was clear from the start: the 3D experience needed to be visually refined, interactive, and fully optimized for web delivery—not a heavy showcase scene.
The entire environment was built and structured inside Spline 3D, allowing seamless embedding into a live website and easy iteration during development.
Live 3D Experience
To ensure transparency and allow stakeholders to experience the project directly, the final Spline scene is publicly viewable:

Why Spline 3D Was Central to This Project
Spline 3D was not just a design tool—it was the core production platform:
Native real-time 3D rendering for browsers
Built-in interaction states and animation timelines
Lightweight scene structure suitable for landing pages
Direct handoff to developers without rebuilding assets
By designing directly in Spline, the project avoided unnecessary conversions and ensured what was designed is exactly what ships on the website.
Visual & Interaction Design
The smart city was intentionally minimal, calm, and realistic:
Neutral tones (white, light grey, concrete) formed the base architecture
Red was used only as a functional accent to indicate services, activity, or connectivity
Clean geometry and restrained beveling maintained clarity
Lighting and shadows were carefully tuned to add depth without increasing render cost
Every visual decision was evaluated through the lens of performance and usability.
Website Optimization Strategy
A strong emphasis was placed on real-world website performance:
Low-to-mid poly assets across the entire city
Modular buildings reused intelligently to reduce draw calls
Minimal textures to keep loading times fast
Icons created as simple 3D forms instead of image-heavy elements
Subtle animations designed to remain GPU-efficient
This ensured the scene could be embedded on a live website without slowing page load or interaction responsiveness.
Iterative Workflow & Collaboration
The project followed a continuous feedback-driven workflow, with frequent updates, live reviews, and refinements:
Multiple passes on color balance and gradient control
Adjustments to icon count, placement, and visibility
Layout restructuring to support development timelines
Final tuning of animation entry states for a smooth landing experience
Despite evolving requirements, the Spline-first approach allowed rapid iteration without sacrificing stability.
Final Outcome
The final deliverable was a fully optimized, production-ready Spline 3D smart city, designed explicitly for website use—not just visual presentation. The project demonstrates how Spline 3D can be leveraged to create interactive, scalable, and performant 3D experiences that integrate cleanly into modern web environments.
This case study stands as an example of how thoughtful optimization, clear visual restraint, and the right toolset can elevate a website’s first impression without compromising performance.
