Join Michael House for an in-depth discussion in this video A midpoint displacement landscape, part of Advanced Unity: 3D Game Programming.
…In this video, I'm going to show you how…you can use midpoint displacement to create terrain.…Midpoint displacement can give us a height map we can generate voxile terrain from.…Height maps are a 2D array of values…that give an elevation point at each grid position.…This means height maps can't contain information like caves or overhangs.…While height maps may seem inferior to the 3D noise we've been generating in…previous videos, they're still an excellent technique…for generating terrain that can look natural.…Height maps allow us to more easily control the realism of the terrain,…by avoiding floating terrain, or terrain structures…that couldn't exist in the real world.…
MidpointDisplacement is a commonly used method for generating terrain height maps.…Let's take a look at how midpoint displacement works in a 1D example.…Midpoint displacement starts with the longest line possible, or…in our 2D case the largest grid size possible.…We then split that line in two, we then set…the midpoint equal to the average of the two positions.…

Q: In the Chapter 3 file EntityLoader.cs, I get an error: DirectoryNotFoundException: Directory 'Assets\' not found. Removing the backslash after 'Assets' fixes it, but then I run into a different error. How do I fix this?
Q: What version of Unity does this course cover?
A: This course requires Unity 4.5.5. The newer versions of Unity have done away with the GUI system used in this course, so the interfaces included for many of the scenes will not work with 4.6 and higher. You can download Unity 4.5.5 at http://unity3d.com/get-unity/download/archive.
Q: The game object in the first chapter's Mouse Input Raycasting sample doesn't appear to follow the mouse. What's wrong?
A: Please enable the Box Collider component (by activating the checkbox next to the component name) on the game object. This is not explicitly mentioned in the video, but it will ensure the raycasts collide with the game object.
