Showcasing a destination has long meant photos and text: images, perhaps a video, a list of features. This works well for conveying information, but it leaves the visitor passive — they look, they don't explore.
Browser-based 3D changes that setup. When a destination is brought to life as an interactive environment, visitors can move through the space, look in any direction and explore details at their own pace. The experience is closer to an actual visit than a photo gallery.
The technology behind this has matured considerably in recent years. WebGL and WebGPU enable real-time 3D rendering directly in the browser without separate installs. 3D Gaussian Splatting allows photorealistic environments to be built from real spaces — without heavy manual 3D modelling.
The practical applications are varied. A tourism destination can let potential visitors explore before a trip. A venue's sales team can walk clients through room configurations remotely. A city or region can offer an interactive overview as a digital marketing asset.
Importantly, this experience works directly in the browser — a link is enough. No apps, downloads or special hardware needed.
At Calesta, we have built 3D environments using the PlayCanvas engine and 3D Gaussian Splatting. The most interesting potential isn't in the technology itself, but in how it changes the relationship between a destination and its visitor: from passive viewer to active explorer.
