Height maps are used to store values such as terrain elevation for the use in 3D computer graphics (bump mapping, displacement mapping, cloud opacity, fractal noise, etc.).
Heightmap's come in two forms; grayscale and color.
Grayscale heightmap's are visualized as luma of grayscale (black to white) with black representing the lowest elevations of the terrain and white the highest elevations (peaks).
Color height map's are visualized through a color gradient (blue to white) with blue being the lowest height and white the highest.
Heighmap Maker is a tool for creating random grayscale and color height maps. The app has an very minimalistic interface and is very easy to use. The user can choose the type of the height map and the output size of the generated map and image. Higher output values generate more detailed and complex images.
Generating maps can be very taxing* on the user's device. The higher the value of the output size the more processing and memory resources are needed for generating an image.
The user can save and share the generated images. All images are in the PNG format.
Heightmap Maker requires these three permissions:
The permission to write on the device's external storage (memory card) for saving images;
The permission to access the network state - App rating, 'Share App' function, Ad's and crash reporting.
The permission for usage of the users identity (required for the 'Share app' feature)
* On lower-end devices, choosing an higher output value for the generated image can sometimes lead to a long period of waiting for the app to finish generating an image preview or even the app crashing due to it reaching it's memory limit for the device. Choosing an lower output value for the generated image is the best solution for those devices.
New updates and features are coming soon.
