From heightmap to real 3D map in 3 easy steps

Step 1. Draw or get a
real world location heightmap

Step 2. Generate and edit
an isometric 3D map

Step 3. Style and design
your 3D terrain map

How it works

3D Map setting

Every angle of vision on the 3D map is possible. You can completely determine the height and map dimension and change it at any time. Also light and shadows are adjustable at will. 8 isometric map angle presets picture a 360 degree angle of vision. So the isometric icon sets will still match the final maps. Manually the map can of course be rotated steplessly. With the map reset function you can go back to the isometric basic setting at any time.

Grayscale Heightmap


A heightmap or heightfield is a raster image used to store values, such as surface elevation data, for display in 3D computer graphics.


A heightmap contains one channel interpreted as a distance of displacement or “height” from the “floor” of a surface and sometimes visualized as luma of a grayscale image, with black representing minimum height and white representing maximum height.



Create your own Heightmap


To create a terrain with the 3D Map Generator a grayscale heightmap is required. That can be existing height maps from outside sources, with the plugin created heightmaps or real world locations from Tangram Heightmapper.


For creating your own heightmap there are extensive tools available in the panel. With Auto-Heightmaps you can generate random heightmasp that can be edited further for example by using the 60+ heightmap brushes. Therefor the Height Color tool could be very helpful to follow defined heights


Get a Heightmap from the Heightmapper Viewer


With the Heightmapper there is a powerful heightmap viewer available. It allows you to find real world locations as heightmaps and easily export them to Photoshop. Of course there are also other heightmap viewer on the web – take a look at the resource link list in the instructions PDF. The 3D terrains created from the heightmaps  can also be textured with – for example – Google textures or Open Streetmaps. The results are really stunning!

Step 2. Create your shape and
simple name the layer „shape“

Step 3. Generate
your 3D terrain map

Grayscale Color Tool

A heightmap consists of grayscales between 0 (black) and 255 (white). With this tool it is easy to select the different grayscales. Additionally you can enter the highest point of your map into the text field on the right side. The tool then calculates which grayscale relates to which height. The value appears above the blue slider. That will help you to generate more accurate terrains. (A) names the reference value that defines the highest point of the map. 500 is set by default. (B) names the middle of the grayscale. So if for instance (A) is 2686, (B) would be 1343.

The surface of the 3D terrain map can be edited further with the different gradient presets, seamless textures, texturing brushes and the Auto-Texture Tool with . Of course even own textures can be embedded easily.


You can generate real contour lines with various spacing freely selectable colors.


There are many presets available to design a great map.


100+ basic isometric icons and elements can be placed on the map with one click in most of the applications. The icon size slider makes it easy to transform them consistently. But you can also easily load your own icons (PSD, PNG) into the library. That makes designing even more comfortable!
