Interactive 3D Model Viewer with Theme Switching

Project Overview
Many online 3D viewers are static, lack customization, and aren’t optimized for performance. My goal was to do some experiments with the 3d libraries and build an interactive and responsive viewer that supports dynamic environments, realistic lighting, and smooth user interaction.
Technical Stack
Three js, Custom Skybox Textures & OrbitControls
Key Features
  • GLB Model Loading: Drag-and-drop file support for loading .glb models instantly.
  • Theme Switching: Day/Night environment changes with skybox textures.
  • Responsive UI: Works across desktop and mobile screens.
  • Real-time Interaction: OrbitControls for zoom, pan, and rotation.
  • Custom Lighting Setup: Directional + ambient lights for realism.
  • Performance Optimizations: DRACO compression & efficient rendering.
Development Process

The workflow for this project began with designing the UI overlay, ensuring a clean and intuitive layout for user interaction. I then implemented the 3D model loading and configured the camera setup to provide optimal viewing angles. To enhance realism, I created custom environment maps for both day and night themes, adding immersive lighting conditions. A toggle switch was integrated to allow seamless theme changes without disrupting the experience. Finally, I applied a series of performance optimizations, including efficient asset loading and rendering improvements, to deliver a smooth and responsive user experience across devices.
