About Crystal Cave

Crystal Cave transports you inside a luminous underground cavern filled with crystalline formations that resonate and glow in harmony with your audio. Stalactites and stalagmites of translucent crystal catch and refract light, creating prismatic color displays that shift with the spectral content of the music. Bass frequencies cause deep resonance vibrations through the cave structure while high frequencies make individual crystal tips sparkle and chime. The cave environment is rendered with careful attention to lighting and atmosphere. Volumetric fog fills the space, catching light from the glowing crystals and creating shafts of colored illumination. The camera slowly moves through the cave, revealing new formations and chambers, each one responding to different aspects of the audio. The sense of discovery and wonder is palpable. Crystal Cave is a deeply immersive effect that creates a complete environment rather than an abstract pattern. The combination of realistic lighting, atmospheric effects, and audio-reactive crystal behavior produces a visualization that feels like exploring an alien world that exists solely within your music.

How it works

Crystal formations are procedurally generated using seeded Voronoi tessellation to determine growth sites, then extruded along randomized axes with faceted geometry. Each crystal is assigned a resonant frequency band. During playback, crystals in active bands increase their emissive intensity and apply a subtle vibration displacement. Volumetric fog is approximated using ray-marched screen-space scattering. The camera follows a pre-computed spline path through the cave, with movement speed tied to overall audio energy. Refraction effects use screen-space techniques to simulate light passing through translucent crystal faces.

Frequently Asked Questions

How is the cave generated?+
The cave geometry is procedurally generated using a seeded algorithm, so the same seed always produces the same cave. You can regenerate with different seeds to find a cave shape you like.
Can I control the camera path?+
The camera follows an automatically generated spline path. You can adjust the movement speed and whether the camera pauses at interesting formations, but manual camera control is not currently supported.
Does this effect run well on laptops?+
Crystal Cave uses optimized rendering techniques including LOD (level of detail) for distant crystals and approximated volumetrics. It targets 60fps on a 2019 MacBook Pro.
