eminakkoc.com(Personal web site)

I have tried kind of a different approach while developing my personal website. Unlike from traditional portfolio sites, which are developed similar to resumé documents, I created a 3d scene (rendered with ThreeJS) which replaces the main router of a web app project.

All routes (server side rendering approach is used with NextJS) which are present on the website are represented in the scene by a building. Instead of clicking a link on a traditional web page, users click those buildings (or building names from menu) to travel to the location of that building and display the server side rendered page.

Users can also walk and look around freely and enjoy the scene with user controls and keyboard shortcuts if they haven’t clicked any building and redirected to any page yet.

Pages are implemented responsive and tested 3d render performances in mobile devices.
