EQ Terrain — a soundscape in motion
The EQ Terrain transforms your music into a three-dimensional wireframe mountain landscape in electric blue. The camera continuously flies over this terrain, like a flight above an imaginary land whose geography is entirely dictated by sound.
What you see
Two terrain planes face each other — one above, one mirrored below — creating a symmetry effect reminiscent of a hollow planet or a dimensional passage. The upper terrain features a bright blue wireframe render; the lower reflection is subtler and translucent. The grid vertices rise or fall according to the amplitude of corresponding frequencies, building sound mountains during intense moments and flattening out in silences.
Three colored orbs float above the terrain: red for bass, cyan for mids, green for treble. Their size and glow instantly show the audio spectrum balance. A cloud of white particles gently rises from the ground, accelerating during energy peaks.
Reading the spectrum
Each column of the grid corresponds to a frequency band. Bass (on the left) creates massive, slow peaks; treble (on the right) generates fine, rapid ridges. The terrain is literally a real-time topographic map of the sound.
Technology
Two PlaneGeometry meshes (40×40 segments = 1,681 vertices each) whose Y positions are updated via the FFT buffer every frame. The camera follows a sinusoidal flyover path computed with Math.sin/cos of time. The orbs are IcosahedronGeometry meshes whose emissiveIntensity varies with bass/mid/treble.
