Landform Explorer 3D

Do you have 3D glasses? Red-green, red-blue and red-cyan glasses all work.
You can change this any time from the menu.

How deep?

Less depth is easier on the eyes. More depth pops out more.

1. Hide the green bar

Put the glasses on and cover the eye behind the green lens, so you look only through the red lens. Slide left until the green bar disappears.

2. Hide the red bar

Now cover the eye behind the red lens, so you look only through the green lens. Slide left until the red bar disappears.
3D mode is just a fun way to play. If your eyes feel tired, take a break or play without glasses.

HOW TO PLAY

  1. The map shows land, sea and different landforms. Read the question and tap the right landform on the map.
  2. Drag to turn the map and look from another side.
  3. Each expedition adds new landforms. Later questions describe a landform instead of naming it: β€œTap the land with water all around it.”
  4. A wrong tap tells you what you tapped, so you learn both!
  5. No mistakes gets ⭐⭐⭐. Each new landform you find goes in your atlas with a real example from around the world.

HOW 3D WORKS

  1. Try this: hold up a finger and look at it with one eye, then the other. It jumps! Your brain uses the jump between your eyes to see depth: stereo vision.
  2. The game draws the map twice, from two eyes a little apart, in red and in green (or blue). The glasses give each eye its own picture, so mountains rise towards you and lakes and valleys sink away.
  3. Map fact: flat maps show height with colours and contour lines. People who make maps from the air use the same trick as your glasses: two photos taken a little apart, viewed one with each eye, make the land pop up in 3D!
