The Field Kit
Splashes that make something from what you bring, or measure what they show.

3D Video
A video is a string of photos, and a computer can guess how far away each part of a photo is.
Model to Splats
A 3D model is usually a mesh: a net of flat triangles with colors or a picture (a texture) painted on them.

Picture Lab
The Picture lab shows a page, a photo, a GIF or a video as Gaussian splats: thousands of small, flat, colored discs, the same stuff every splash here is made of.
Splash Book
A book is a stack of pages bound along one edge, so you can turn them one at a time.
Thermal Ellipsoids
Crystallography describes an atom's average position and spread with a displacement tensor.
Scan and measure
Airport X-ray
An airport scanner sends a fan of X-rays through each bag as the belt carries it past, and a row of detectors measures what gets through, one line at a time.
Electron Microscope
A scanning electron microscope sweeps a fine beam of electrons across a sample in a vacuum.
CT Explained
A CT scanner (computed tomography) turns an X-ray tube and a curved row of detectors around the object, taking hundreds of views from every side.
Walnut CT
This is a real walnut, scanned with X-ray CT at CWI in Amsterdam: more than a thousand X-ray pictures taken from all around it, worked back into a volume of how dense the walnut is at every point.
Room Echo Meter
Reverberation is sound that keeps bouncing around a room after its source stops.
Super-Res Microscope
Ordinary light microscopy struggles to separate nearby objects about 200 to 300 nanometers apart.
QR codes
QR Damage Lab
QR codes still scan when part of them is lost, because error correction can rebuild missing codewords: about 7, 15, 25 or 30 percent at levels L, M, Q and H.
Triple QR
One square holds three QR codes here: the first sets each module's red, the second its green and the third its blue.
Sound and light
Chladni Plate
In 1787 Ernst Chladni sprinkled sand on a metal plate and drew a violin bow along its edge.
Screen
A screen made of splats shows a video or a GIF: every pixel of the picture is a small splat whose color changes with each frame.
Splat Mirror
Tap “Start camera” and each splat takes the color of its place in the picture, so the mirror shows you, live.
In every Splash
Every Splash takes the same effects: Poke, Wind, Dissolve, Twist, Slice, Drop, Magnet, Paint, Move, and Clay. They are in the Playground's Effects sheet, each with its own settings.
Views show how splats work: Cutaway, Show the splats, Heat map, and Scrub and slow motion.
Make and share
Save a picture, a turntable video, a GIF, or a PDF that carries the Splash's credits. Record up to a minute with sound. Copy a link that keeps the view, the effects, and the splat count. Share and embed has every option.
