Every effect

There are 94 effects and 16 looks. These pages are written from the library's own table of effects, and the pictures are the effects themselves on one small moving scene, so this is what the library has.

Each effect is one line to turn on. The value in the brackets is the one a plain number (or name) sets, and every other setting goes in by name: glow(0.8, { radius: 40 }), or in Python glow(0.8, radius=40). A setting can be changed at any time: shine.radius = 60.

Every effect also has amount, from 0 to 1: how much of it is mixed in. Lengths are in the scene's points and angles in degrees. A place (x, y) is the middle of the picture unless you say. A name with a capital in JavaScript has an underscore in Python: zoomBlur is zoom_blur.

Shapes of the picture

kaleidoscope, mirror, pixelate, waves, ripple, wobble, swirl, fisheye, tunnel, tile, droste, rotozoom, hexagons, glassTiles, frosted, heatHaze, caustics, shake, punch

EffectWhat it is
kaleidoscopeOne slice of the picture, folded round and round. The slice starts at the middle and points right: turn it with angle.
mirrorOne half of the picture shown on both sides, or one quarter in all four.
pixelateBig square pixels.
wavesThe picture ripples like a flag in the wind.
rippleRings spreading from a point, as from a stone dropped in water.
wobbleThe picture wobbles like jelly, or something seen under water.
swirlThe middle of the picture twisted round, like stirred paint.
fisheyeA bulge, as through a round lens. Below zero it pinches instead.
tunnelThe picture becomes the walls of a tunnel you are flying down.
tileThe picture repeated in rows and columns.
drosteThe picture inside itself, smaller each time, for ever. With a twist it winds in as a spiral.
rotozoomThe picture tiled, turning and zooming: an old demo-scene favourite.
hexagonsSix-sided pixels, like a honeycomb.
glassTilesSeen through a wall of glass blocks.
frostedSeen through frosted glass.
heatHazeThe shimmer of hot air rising.
causticsThe net of bright lines that sunlight makes on the floor of a pool.
shakeThe whole picture shakes. Set strength when something hits, and let it fall away.
punchA zoom in towards a point. Tie its strength to the beat.

Shapes of the picture has each one's picture and settings.

Blur and light

zoomBlur, spinBlur, motionBlur, tiltShift, lightRays, streaks, softFocus, blur, glow

EffectWhat it is
zoomBlurRushing towards a point.
spinBlurSpinning round a point.
motionBlurMoving fast in one direction.
tiltShiftA band in focus and the rest blurred, which makes a scene look like a tiny model.
lightRaysRays of light streaming out from a point, through whatever is bright.
streaksLong sideways flares from bright lights, as a film camera makes.
softFocusA soft, dreamy haze over the bright parts.
blurOut of focus.
glowBright things shine and spread light around them.

Blur and light has each one's picture and settings.

What was drawn stays

smear, stutter, trails

EffectWhat it is
smearWhat was drawn is carried away on a slow current, like wet paint.
stutterOnly so many new pictures a second: the last one is held between them.
trailsWhat was drawn stays and fades. With zoom, spin and hue it becomes the classic screensaver tunnel.

What was drawn stays has each one's picture and settings.

Colours

rgbSplit, hue, saturate, brighten, contrast, invert, posterize, tint, duotone, colourCycle, gradientMap, thermal, nightVision, sepia, threshold, solarize, colourBleed, rainbowEdges

EffectWhat it is
rgbSplitRed and blue pulled apart, like a cheap lens or a bad signal.
hueEvery colour moved round the colour wheel. With speed, the colours keep turning.
saturateMore colour, or less: at 0 the picture is grey.
brightenBrighter, or darker below 1.
contrastLights lighter and darks darker.
invertA negative: every colour swapped for its opposite.
posterizeOnly a few shades of each colour, like a poster.
tintSeen through coloured glass.
duotoneTwo colours only: one for the dark parts and one for the light.
colourCycleBrightness becomes a colour from a palette, and the colours move round.
gradientMapBrightness becomes a colour from a palette, dark to light.
thermalA heat camera: cold is dark blue, hot is yellow and white.
nightVisionGreen, grainy and bright in the dark, like a night-vision scope.
sepiaThe warm brown of an old photograph.
thresholdTwo colours and nothing between: dark or light.
solarizeThe bright parts turned to their opposite, as in an over-exposed photograph.
colourBleedColours smeared sideways, as on old videotape.
rainbowEdgesEvery edge in the picture drawn in rainbow colours.

Colours has each one's picture and settings.

Screens and old computers

scanlines, crt, glitch, letters, dither, interlace, led

EffectWhat it is
scanlinesDark lines across the picture, as on an old screen.
crtAn old television: curved glass, lines, and thin stripes of red, green and blue.
glitchA broken signal: blocks that jump sideways, a line that tears, a band of snow.
lettersThe picture made of marks, as an old terminal would show it.
ditherA few colours made to pass for many with a pattern of dots, as old computers did.
interlaceEvery other line dark, swapping each frame, like old video.
ledA wall of round lamps.

Screens and old computers has each one's picture and settings.

Drawn, printed and painted

edges, dots, emboss, sharpen, sketch, cartoon, stainedGlass, crosshatch, oil

EffectWhat it is
edgesOnly the outlines, each in its own colour.
dotsPrinted in dots, big where the picture is bright, as a comic or a newspaper is.
embossPressed into grey metal: only the bumps and hollows show.
sharpenCrisper edges.
sketchA pencil drawing on paper.
cartoonFlat colours and black outlines.
stainedGlassPieces of coloured glass with dark lead between them.
crosshatchShaded with crossing pen lines: more lines where it is darker.
oilSmoothed into patches of colour, like oil paint. Heavy: it looks at 36 places for every pixel.

Drawn, printed and painted has each one's picture and settings.
