Adaptive Quality When the Device Gets Hot

Thermal and frame-time pressure should lower cost without rewriting the engine. How adaptive quality governance keeps exports and live previews honest on real devices.

Engines That Stay Distinct With Audio Muted

A visualizer catalogue only works if engines still look like themselves when the track is silent. Here is how distinct draw identities survive muted preview, reduced motion, and still capture.

The Par Wall Mode: A Rig With No Beams At All

Par Wall draws no beams and no cones. It is a grid of lamps chasing group by group, and the most interesting thing in it is what the additive blend forced the halo to become.

The Laser Sweep Mode: A Stroke, Not a Cone

Laser Sweep is the only mode in its engine that draws strokes instead of cones, which is exactly why Thickness is scoped to it alone and Beam spread is scoped away from it.

The Dune Field Mode: The Only Terrain That Never Strokes a Line

Dune Field is the only mode in its engine with no stroke anywhere in its branch, which is why Thickness is scoped out of it and present on all five of its neighbours.

The Contour Map Mode: The Terrain That Does Not Hide What Is Behind It

Contour Map skips the occluding pass every other ridge mode in its engine performs. Dropping the hidden-line step is exactly what turns a landscape into a plate you read from above.

The Wire Polyhedron Mode: The Edge Threshold Shrinks as You Add Nodes

Wire Polyhedron spaces its vertices on a sphere with the golden angle and joins any pair closer than a threshold that falls as the count rises. That falling threshold is why it stays a shell.

The Orbiting Bars Mode: Bar Width Is the Circumference, Divided

Orbiting Bars never lets you make a solid disc by mistake, because it derives every bar's stroke width from the circumference and the count rather than from a width control.

The Waveform Ring Mode: The Trace Bent Around a Reserved Middle

Waveform Ring is the default mode of the Logo engine and the one that makes a brand mark react. Every radius is measured out from the artwork's safe circle, so nothing can ever cross it.

The Waveform Filled Mode: A Closed Path Back to the Baseline

The Waveform engine's area mode closes its trace back along the baseline, fills it translucently, and then strokes the outline on top. Here is why the order matters and what the depth control does when there is only one row.

The Particle Vortex Mode: The One Tunnel Branch That Does Not Return

Particle Vortex is the only mode in its engine that renders two passes in one frame: a spiral of particles, and then the same ring corridor everything else draws. They travel in opposite directions.

The Corridor Grid Mode: Rings Alone Are Not a Corridor

Corridor Grid adds twenty lines that nothing else in the engine draws. Without them a corridor is a stack of nested rectangles; with them it is a surface running away from you.

The Piano/Step Grid Mode: Quantised to Whole Cells

Piano/Step Grid rounds every column to a whole number of cells and paints the dividers in the background colour, which is why Background is one of the few controls this engine opens up to layers.

The Linear Equalizer Mode: Flush on the Edge, Rounded Only at the Cap

Linear Equalizer sits on the frame edge on purpose, rounds only the two corners at the top of each bar, and runs a gloss across the field that brightens without changing a single bar's height.

Read
Audio & Reactivity7 min read

The Frequency Ridge Mode: Only the Front Row Is a Ridge

Frequency Ridge strokes its front row at more than double the width of every row behind it, fills only the first six, and is the one mode in its engine that reads the noise control.

The Line Spectrum Mode: The Axis Is Logarithmic Because the Bins Are

Line Spectrum draws its samples at evenly spaced x positions and still gives you a logarithmic frequency axis. The curve is in the analyser, not in the renderer, and that distinction is worth understanding.

The Sunburst Mode: A Ray Fan Centred on Twelve O'Clock

Sunburst fans frequency rays around a reserved centre. The fan is built outward from the top of the frame, which is what makes a partial sweep symmetric instead of lopsided.

The Glyph Field Mode: A Column Is a Band

Glyph Field lays glyphs on a grid and binds every column to its own slice of the spectrum. A glyph changes character when its column crosses a threshold, not when the clock says so.

The Ink Diffusion Mode: A Colony That Moves Every Fourth Beat

Ink Diffusion holds its arrangement for four beats and then moves the whole colony at once. Here is why that interval exists, and which of its shipped defaults does nothing at all.

The Flow Field Mode: Steering Is the Whole Difference

Flow Field and its sibling read the same field and look nothing alike. The difference is one number: how hard a strand is steered toward the direction the field is pointing.

The Fountain Burst Mode: An Arc That Is Culled, Never Clamped

Fountain Burst launches arcs from the bottom edge and deletes them below it. Here is the age clock, the parabola, and the two controls it ships that its own draw branch never reads.

The Follow Spot Mode: A Target That Only Moves on the Beat

Follow Spot is one fixture tracking a point that relocates every second beat and holds still in between. It is also the only mode in Stage Lights that is faded rather than cued.

The Canyon Scroll Mode: Containment on a Vertical Offset

Canyon Scroll mirrors the Terrain heightfield above and below a travelling corridor whose walls already sit on the frame edge at the horizon. That is why its containment rule is not a radius.

The Kinetic Reveal Mode: Assembling a Mark Across a Bar

Kinetic Reveal lights wedges around your artwork in turn so the mark assembles over a four-beat bar rather than fading in. Here is the bar clock, and the rule that keeps geometry off the logo.

The Oscilloscope/Lissajous Mode: A Real Second Channel

Oscilloscope/Lissajous needs two channels to draw a figure, and a delayed copy of the first one will not do. Here is the filter that produces a genuine quadrature partner, and why the figure used to collapse to a line.

The Waveform Tube Mode: The Corridor That Reads Live

Every ring in the Tunnel engine freezes a snapshot of the spectrum at birth and carries it forward. Waveform Tube is the exception: its surface is the time-domain trace, right now.

The Warp Field Mode: A Streak Carries the Beat It Was Born On

Warp Field draws streaks rather than rings, because a ring is the same shape however fast it travels. Each streak also remembers whether it was born on a beat, and keeps that mark all the way in.

The Radial Bars Mode: The Only Contained Layout in Bars

Radial Bars takes an early exit from the Bars draw path, which is why half the engine's controls do not apply and why it is the one layout the frame margin governs.

The Center Mirror Mode: Half the Headroom, Both Ways

Center Mirror grows bars in two directions from the middle of the frame, which halves the room each one has. Here is the budget that fixed it, and the gloss that brightens bars without lying about their height.

The Mirrored Area Mode: A Reflection Has to Be Rebuilt

Mirrored Area reflects a solid spectrum shape across its baseline. Doing that on a canvas is not a transform and a second stroke, and the mode is named after the bug that taught us so.

The Spectrogram Waterfall Mode: Speed Is a Stride, Not a Push Rate

Spectrogram Waterfall draws rows of spectral history receding into the frame. Speed does not change how fast the buffer fills; it changes how far apart in time the drawn rows are.

The Pulse Orb Mode: A Gradient, a Ray Fan and a Reserved Middle

Pulse Orb is the Radial engine's default and its simplest scene: one radial gradient, one fan of rays over it, and a centre that geometry is not allowed to cross.

The Mandala Mode: Layered Ray Fans That Count Down

Mandala is not rings at different radii. It is several ray fans stacked in the same annulus, each with fewer rays than the last, counter-rotating and offset by Twist.

The ASCII Cascade Mode: Every Glyph Swaps on Its Own Band

ASCII Cascade is a spectrum read left to right, one column per band, where a glyph changes only when its own column crosses a threshold. Here is why that is a visualisation and a shared counter is not.

The Word Wave Mode: Kinetic Type Needs an Overshoot

Word Wave pops each letter on an ease that overshoots and settles, and lights them in groups so the word reads across the bar. Here is the difference between kinetic type and text that scales with the volume.

The Crystal Growth Mode: Structure That Accretes Instead of Breathing

Crystal Growth adds a segment on every beat and keeps it. A structure that only oscillates cannot read as growth, because nothing is ever built. Here is how the accretion works.

The Ripple Blossom Mode: Interference Needs More Than One Ring

Ripple Blossom keeps several beat-born rings alive at once, which is the only way concentric waves can interfere. Here is the ring pool, the petal envelopes and the containment rule underneath both.

The Ribbon Flow Mode: Why a Ribbon Is Not a Thick Line

Ribbon Flow is the only mode in Trails drawn as a two-edged shape rather than a stroke, because a stroked line cannot change width along its length. Here is what that buys and what it costs.

The Comet Shower Mode: Four Edges, and Every Comet Its Own Course

Comet Shower enters from all four edges of the frame and every strand holds its own course. Here is the spawn geometry, the steering, and why the tail is correct from a comet's first frame.

The Constellation Mode: Sparse on Purpose

Constellation ships a fraction of the particles the other modes do, and that is the design. Here is why the links only read as a constellation while the nodes stay countable.

The Stage Lights Engine: A Lighting Rig, Not a Readout

Beams, haze, floor pools and chases cued by the beat. Stage Lights visualises the room instead of the signal, and it is the only engine in the catalog built around a lighting desk rather than a graph.

The Terrain Engine: The Last Few Seconds of Your Track as Landscape

Every other engine draws this frame. Terrain draws the last few seconds: each frame pushes a spectrum row into a receding heightfield, so a kick becomes a ridge you can still see four seconds later.
