A behind-the-scenes look at blending NPR shading, sound, and interaction to shape a meditative WebGL scene. 3D case study postprocessing Three.js WebGL What would it look like if a Three.js/WebGL 3D web experience behaved like a watercolor painting—fluid, responsive, and interactive? In Susurrus , I explore this idea using Non-Photorealistic Rendering (NPR), approaching stylization as both an aesthetic and a performance consideration. In this case study, I’ll walk through how this project was designed and built.

In Susurrus , the scene feels natural and cozy at first glance, but subtly surreal and absurd upon closer inspection. Soft sound design and a calm atmosphere create a meditative, lo-fi–like space.…
