Spline 3D: a heavy bet that makes the right first impression

A portfolio has one job: make someone pause and pay attention. A 3D scene that responds when you move your mouse does that. Is it strictly necessary? No. Does it load as fast as plain text? Definitely not. But does it make a recruiter or potential client think 'this person builds interesting things'? Yes. Sometimes the right trade-off is choosing impact over speed.

In a world where everyone can spin up a polished-looking site in minutes, standing out is harder than ever. A well-crafted 3D element signals that you care about craft and aren't afraid of technical challenges. It's the digital equivalent of a firm handshake — it doesn't prove competence, but it creates a strong first impression that earns you the next few seconds of someone's attention.

Spline has a free visual editor where you design 3D scenes by dragging shapes, adjusting lighting, and positioning cameras — no 3D modeling experience required. Once your scene looks right, you export it as a link and embed it in your site. The key is to load it lazily, meaning the rest of your page appears first and the 3D scene fills in after. That way visitors aren't staring at a blank screen while the 3D content downloads. Always test on phones — 3D is demanding on mobile devices and can drain batteries fast.

Hero sections on portfolios or creative agency sites — places where visual impact justifies the heavier page load. Don't use it on pages where speed matters more than wow factor, like a blog, a documentation site, or anything with real users who'll bounce if the page takes too long. For this portfolio, the trade-off was clear: the hero is the first impression, and a memorable first impression is worth a slightly slower load.
