+I'm taking the Game Engine Architecture class at Reykjavík University.  My group
+just finished our midterm [project][] where we played around with procedural
+terrain generation in [Unity][].  It was a lot of fun and I really enjoyed
+creating terrain out of numbers, so I thought I'd write up a little introduction
+to a few of the algorithms.  For this post we'll look at Midpoint Displacement.

+## Terrain Generation
+
+Procedural generation is a pretty big field. The [Wikipedia
+article][wikipedia-pg] gives a pretty brief overview.  The [Procedural Content
+Generation Wiki][pcg-wiki] is an entire wiki devoted to procedural generation.
+There's also a small but active [subreddit][r-pg] for interested folks.
+
+Today we're just going to look at a single algorithm for generating
+realistic-looking terrain called "Midpoint Displacement".  It's relatively
+simple (compared to other algorithms) but it produces terrain that actually
+looks kind of cool.

+[pcg-wiki]: http://pcg.wikidot.com/
+[r-pg]: https://www.reddit.com/r/proceduralgeneration/
+
+## Resources, Code, and Examples
+
+There are a lot of resources for learning how terrain generation algorithms
+work.  For midpoint displacement I used the [Wikipedia article][wikipedia-ds],
+the [PCG Wiki article][pcgw-midpoint], and academic papers like [this
+one][paper].
+
+Unfortunately, while there are a *lot* of places that describe algorithms like
+this, there are relatively few that explain it thoroughly.  Academic papers in
+particular tend to have a really bad case of
+[draw-the-rest-of-the-fucking-owl-syndrome][owl].  They tend to slap an equation
+or two on the page and move on without showing any code.
+
+As anyone who's done much programming knows, there's a big difference between
+saying something like "set the midpoints of the diamonds to the average of the
+corners" and making a computer actually *do* that.  How do we iterate over the
+array (row-major or column-major)?  Does it matter (yes: if you care about cache
+coherency)?  What about the edges where there are fewer corners?  How random
+(and how fast) is our random number generator (and how much do we care)?  How do
+we write all this code so we can actually read it six months later?
+
+So I'm going to try to do my part to improve the situation by not just
+describing the algorithm, but showing *actual code* that runs and generates
+a terrain.
+
+TODO The code is at:

+### Wisp
+
+I'm using a language called [Wisp][wisp].  It's a small, Clojure-inspired
+dialect of Lisp that compiles down to vanilla Javascript.
+
+I went with Javascript because it means I can actually put demos inline in this
+post.  Sometimes it's so much easier to explain something when you can actually
+see it running.
+
+I've tried to write the code so that it's readable even if you don't know Lisp.
+The point of me showing you this code is not to give you something to copy and
+paste.  The point is that until you *actually write and run* the code, you don't
+know all the edge cases and problems that can happen.  So by making examples
+that actually run I feel a bit more confident that I'm explaining this well
+enough.
+
+I haven't focused on performance at all.  If you want a fast implementation of
+this, you'll probably want to use a language with real arrays (contiguous chunks
+of memory holding a bunch of unboxed floats).

+### Three.js
+
+[Three.js][three.js] is a Javascript library for 3D rendering.  I'm using it
+here to get something on the screen you can play with.  I'm not going to cover
+the code to put the terrains on the screen because it's really an entirely
+separate problem to generating terrain.
+
+I also haven't been able to get these demos working on my iPhone.  Sorry about
+that, but I'm not much of a frontend developer.  You'll have to use a computer
+to see the demos.  [Pull requests][slc] are welcome.

+
+## Heightmaps
+
+Let's get started.  The main data structure we're going to be using here is
+called a [heightmap][].
+
+### Overview
+
+Heightmaps are essentially just big two-dimensional arrays of numbers in a given
+range that represent the height of the ground at a given point.  For example,
+a heightmap with a small "mountain" in the middle might look like:
+
+    :::text
+    [[0, 0, 2, 0, 0],
+     [0, 2, 5, 1, 0],
+     [2, 5, 9, 4, 1],
+     [0, 1, 4, 1, 0],
+     [0, 0, 1, 0, 0]]
+
+In practice, heightmaps are often represented as a single-dimensional array
+instead to ensure that all the data is together in one big hunk of memory:
+
+    :::text
+    [0, 0, 2, 0, 0,
+     0, 2, 5, 1, 0,
+     2, 5, 9, 4, 1,
+     0, 1, 4, 1, 0,
+     0, 0, 1, 0, 0]
+
+The type and range of the numbers in the map varies by program and programmer.
+Some programs use nonzero integers, some use all the integers, some use floating
+point, etc.
+
+The heightmaps in this post will contain floats from `0.0` to `1.0`.  I like
+using floats between zero and one because it's easy to roughly visualize them in
+your head (e.g. `0.1` is ten percent of the maximum height).
+
+One common way to visualize heightmaps by turning them into greyscale images
+with one pixel per number, with black pixels for lowest value in the map's range
+and white for the highest.  The [Wikipedia article][heightmap] has an example of
+this.
+
+[heightmap]: https://en.wikipedia.org/wiki/Heightmap
+
+### Code
+
+We're going to start by writing a few functions that will hide away the internal
+details of how our heightmaps are implemented, so we can talk about them in
+nice, high-level terms for the rest of the program.  We'll also need a couple of
+helper functions along the way.
+
+We'll start with something to create a heightmap:
+
+    :::clojure
+    (defn make-heightmap [exponent]
+      (let [resolution (+ 1 (Math.pow 2 exponent))]
+        (l (+ "Creating " resolution " by " resolution " heightmap..."))
+        (def heightmap
+          (new Array (* resolution resolution)))
+        (set! heightmap.resolution resolution)
+        (set! heightmap.exponent exponent)
+        (set! heightmap.last (- resolution 1))
+        (zero-heightmap heightmap)))
+
+`make-heightmap` takes an exponent and creates a heightmap.  For reasons that
+will become clear later all of our heightmaps will be square, and they'll need
+to have \\(2^n + 1\\) rows and columns.  This means we can make heightmaps of
+sizes like 3x3, 5x5, 9x9, 17x17, 33x33, etc.  So our function just takes the
+\\(n\\) to use and creates a correctly-sized array.
+
+(If you've ever poked around with Unity's Terrain objects you might recognize
+these "powers of two plus one".)
+
+We create a new array (1-dimensional) and store a few pieces of extra data on it
+for later use.  `last` is the index of the last row/column, so for a 3x3 array
+it would be `2`.
+
+`l` is just a simple little logging function:
+
+    :::clojure
+    (defn l [v]
+      (console.log v))
+
+We'll need to zero out the heightmap as well:
+
+    :::clojure
+    (defn zero-heightmap [heightmap]
+      (do-times i heightmap.length
+        (set! (aget heightmap i) 0.0))
+      heightmap)
+
+`zero-heightmap` just iterates from `0` to `heightmap.length` and sets each
+element to `0.0`.  Wisp doesn't have syntax to loop from 0 to some number, but
+it's a Lisp, so we can make some:
+
+    :::clojure
+    (defmacro when [condition & body]
+      `(if ~condition
+         (do ~@body)))
+
+    (defmacro do-times [varname limit & body]
+      (let [end (gensym)]
+        `(let [~end ~limit]
+           (loop [~varname 0]
+             (when (< ~varname ~end)
+               ~@body
+               (recur (+ 1 ~varname)))))))
+
+If you're not a Lisp person, don't sweat this too much.  Just trust me that
+`(do-times i 10 (console.log i))` will print the numbers `0` to `9`.
+
+Now that we can create a heightmap, we'll probably want to be able to read its
+elements:
+
+    :::clojure
+    (defmacro heightmap-get [hm x y]
+      `(aget ~hm (+ (* ~y (.-resolution ~hm)) ~x)))
+
+    (defn heightmap-get-safe [hm x y]
+      (when (and (<= 0 x hm.last)
+                 (<= 0 y hm.last))
+        (heightmap-get hm x y)))
+
+`heightmap-get` handles the nasty business of translating our human-thinkable
+`x` and `y` coordinates into an index into the single-dimensional array.  It's
+not particularly fast (especially if the compiler won't inline it), but we're
+not worried about speed for this post.
+
+`heightmap-get-safe` is a version of `heightmap-get` that will do bounds
+checking for us and return `nil` if we ask for something out of range.
+Javascript will return `undefined` if you ask for a non-existent index, but
+because we're storing the array as one big line of data, using a `y` value
+that's too big will actually "wrap around" to the next row, so it's safer to
+just check it explicitly.
+
+Of course we'll also want to be able to set values in our heightmap:
+
+    :::clojure
+    (defmacro heightmap-set! [hm x y val]
+      `(set! (heightmap-get ~hm ~x ~y) ~val))
+
+
+And finally, we'll want to be able to "normalize" our array.  During the course
+of running our algorithm, it's possible for the values to become less than `0.0`
+or greater than `1.0`.  We want our heightmaps to contain only values between
+zero and one, so rather than change the algorithm we can just loop through the
+array at the end and "squeeze" the range down to 0 and 1 (or "stretch" it if
+it ends up smaller):
+
+    :::clojure
+    (defn normalize [hm]
+      (let [max (- Infinity)
+            min Infinity]
+        (do-times i hm.length
+          (let [el (aget hm i)]
+            (when (< max el) (set! max el))
+            (when (> min el) (set! min el))))
+        (let [span (- max min)]
+          (do-times i hm.length
+            (set! (aget hm i)
+              (/ (- (aget hm i) min)
+                 span))))))
+
+## Random Noise
+
+Now that we've got a nice little interface to heightmaps we can move on to
+actually making some terrain!  Before we dive into midpoint displacement, let's
+get a [black triangle][] on the screen.  We'll start by just setting every point
+in the heightmap to a completely random value.
+
+    :::clojure
+    (defn rand []
+      (Math.random))
+
+    (defn rand-around-zero [spread]
+      (- (* spread (rand) 2) spread))
+
+    (defn random-noise [heightmap]
+      (do-times i heightmap.length
+        (set! (aget heightmap i) (rand))))
+
+Let's see it!  Hit the "refresh" button to create and render the terrain.  You
+can keep hitting it to get fresh terrains.
+
+<div id="demo-random" class="threejs"></div>
+
+Not really a very fun landscape to explore, but at least we've got something
+running.  Onward to the real algorithm.
+

+
+## Midpoint Displacement
+
+Midpoint displacement is a simple, fast way to generate decent-looking terrain.
+It's not perfect (you'll notice patterns once you start viewing the mesh from
+different angles) but it's a good place to start.
+
+The general process goes like this:
+
+1. Initialize the four corners of the heightmap to random values.
+2. Set the midpoints of each edge to the average of the two corners it's
+   between, plus or minus a random amount.
+3. Set the center of the square to the average of those edge midpoints you just
+   set, again with a random jitter.
+4. Recurse on the four squares inside this one.
+
+That's the standard description.  Now let's draw the fucking owl.
+
+### Initialize the Corners
+
+The first step is pretty easy: we just need to take our heightmap:
+
+<pre class="lineart">
+               Column
+          0   1   2   3   4
+        ┌───┬───┬───┬───┬───┐
+      0 │   │   │   │   │   │

+      4 │   │   │   │   │   │
+        └───┴───┴───┴───┴───┘
+</pre>
+
+Find the corners:
+
+<pre class="lineart">
+               Column
+          0   1   2   3   4

+      4 │ ◉ │   │   │   │ ◉ │
+        └───┴───┴───┴───┴───┘
+</pre>
+
+And shove random values in them:
+
+<pre class="lineart">
+               Column
+          0   1   2   3   4
+        ┌───┬───┬───┬───┬───┐
+      0 │ 2 │   │   │   │ 8 │

+      1 │   │   │   │   │   │
+    R   ├───┼───┼───┼───┼───┤
+    o 2 │   │   │   │   │   │

+      3 │   │   │   │   │   │
+        ├───┼───┼───┼───┼───┤
+      4 │ 0 │   │   │   │ 3 │
+        └───┴───┴───┴───┴───┘
+</pre>
+
+(I'm using 0 to 10 instead of 0 to 1 because it's easier to read in the
+ASCII-art diagrams.)
+
+    :::clojure
+    (defn mpd-init-corners [heightmap]
+      (heightmap-set! heightmap 0 0 (rand))
+      (heightmap-set! heightmap 0 heightmap.last (rand))
+      (heightmap-set! heightmap heightmap.last 0 (rand))
+      (heightmap-set! heightmap heightmap.last heightmap.last (rand)))
+
+    (defn midpoint-displacement-d1 [heightmap]
+      (mpd-init-corners heightmap))
+
+That was easy.
+
+<div id="demo-mpd-1" class="threejs"></div>
+
+### Set the Edges
+
+For the next step, we need to take our square heightmap with filled-in corners
+and use the corners to fill in the middle element of each edge:
+
+<pre class="lineart">
+               Column

+
+This is why the size of the heightmap has to be \\(2^n + 1\\) -- the \\(+ 1\\)
+ensures that the sides are odd lengths, which makes sure they *have* a middle
+element for us to set.
+
+Let's make a couple of helper functions:
+
+    :::clojure
+    (defn jitter [value spread]
+      (+ value (rand-around-zero spread)))
+
+    (defn midpoint [a b]
+      (/ (+ a b) 2))
+
+    (defn average2 [a b]
+      (/ (+ a b) 2))
+
+    (defn average4 [a b c d]
+      (/ (+ a b c d) 4))
+
+`jitter` is just a nice way of saying "take this point and move it a random
+amount up or down".
+
+The other three functions are pretty self-explanatory.  Also, two of them are
+exactly the same function!  There's a reason for this.
+
+Lately I've started digging into [SICP][] again and watching the [lectures][].
+Abelson and Sussman practice a style of programming that's more about "growing"
+a language to talk about a problem you're trying to solve.  So you start with
+the base programming language, and then define new terms/syntax that let you
+talk about your problem at the appropriate level of detail.
+
+So in this case, we've got two functions for conceptually different tasks:
+
+* `midpoint` finds the middle point between two points (indexes in an array in
+  this case).
+* `average2` finds the average of two values (floating point height values
+  here).
+
+They happen to be implemented in the same way, but I think giving them different
+names makes them easier to talk about and easier to keep straight in your head.
+
+    :::clojure
+    (defn mpd-displace [heightmap lx rx by ty spread]
+      (let [cx (midpoint lx rx)
+            cy (midpoint by ty)
+
+            bottom-left (heightmap-get heightmap lx by)
+            bottom-right (heightmap-get heightmap rx by)
+            top-left (heightmap-get heightmap lx ty)
+            top-right (heightmap-get heightmap rx ty)
+
+            top (average2 top-left top-right)
+            left (average2 bottom-left top-left)
+            bottom (average2 bottom-left bottom-right)
+            right (average2 bottom-right top-right)]
+        (heightmap-set! heightmap cx by (jitter bottom spread))
+        (heightmap-set! heightmap cx ty (jitter top spread))
+        (heightmap-set! heightmap lx cy (jitter left spread))
+        (heightmap-set! heightmap rx cy (jitter right spread))))
+
+    (defn midpoint-displacement-d2 [heightmap]
+      (mpd-init-corners heightmap)
+      (mpd-displace heightmap
+                    0 heightmap.last
+                    0 heightmap.last
+                    0.1))
+
+`mpd-displace` is the meat of the algorithm.  It takes a heightmap, the spread
+(how much random "jitter" to apply after averaging the values), and four values
+to define the square we're working on in the heightmap:
+
+* `lx`: the x coordinate for the left-hand corners
+* `rx`: the x coordinate for the right-hand corners
+* `by`: the y coordinate for the bottom corners
+* `ty`: the y coordinate for the top corners
+
+For the first iteration we want to work on the entire heightmap, so we pass in
+`0` and `heightmap.last` for the left/right and top/bottom indices.
+
+<div id="demo-mpd-2" class="threejs"></div>
+
+Run the demo a few times.  Look at how the midpoints fall between the corner
+points because they're averaged (with a little bit of jitter thrown in).

+### Set the Center
+
+The next step is to set the center element of the square to the average of those
+midpoints we just set, plus a bit of jitter:

+We can add this to the displacement function pretty easily:
+
+    :::clojure
+    (defn mpd-displace [heightmap lx rx by ty spread]
+      (let [cx (midpoint lx rx)
+            cy (midpoint by ty)
+
+            bottom-left (heightmap-get heightmap lx by)
+            bottom-right (heightmap-get heightmap rx by)
+            top-left (heightmap-get heightmap lx ty)
+            top-right (heightmap-get heightmap rx ty)
+
+            top (average2 top-left top-right)
+            left (average2 bottom-left top-left)
+            bottom (average2 bottom-left bottom-right)
+            right (average2 bottom-right top-right)
+            center (average4 top left bottom right)]
+        (heightmap-set! heightmap cx by (jitter bottom spread))
+        (heightmap-set! heightmap cx ty (jitter top spread))
+        (heightmap-set! heightmap lx cy (jitter left spread))
+        (heightmap-set! heightmap rx cy (jitter right spread))
+        (heightmap-set! heightmap cx cy (jitter center spread))))
+
+And now our center is ready to go:
+
+<div id="demo-mpd-3" class="threejs"></div>
+
+### Iterate
+
+To finish things off, we need to iterate so that we can fill in the rest of the
+values in progressively smaller squares.
+
+A 3x3 square is the base case, because its corners will be filled in to start,
+and the edges and midpoint get filled in.  We just call our displacement
+function with the top/bottom/left/right values defining the square and we're
+done.
+
+A 5x5 starts with one iteration that displaces the whole map.  Then it does
+another "pass" that displaces each of the 3x3 "sub-squares":

+
+Let's think about what's happening here.
+
+* On pass `0`, we break up the grid into a 1x1 set of "chunk" and displace it.
+* On pass `1`, we break up the grid into a 2x2 set of chunks and displace them.
+* On pass `2`, we break up the grid into a 4x4 set of chunks and displace them.
+
+This 9x9 heightmap was made with an exponent of 3 (\\(2^3 + 1 = 9\\)) and we
+need 3 "passes" to finish it.  This isn't a coincidence -- it's the reason we
+chose our heightmap resolutions to be \\(2^n +1).
+
+At iteration \\(i\\), we need to displace a \\(2^i\\)x\\(2^i\\) collection of
+squares.
+
+    :::clojure
+    (defn midpoint-displacement [heightmap]
+      (mpd-init-corners heightmap)
+      (loop [iter 0
+             spread 0.3]
+        (when (< iter heightmap.exponent)
+          (let [chunks (Math.pow 2 iter)
+                chunk-width (/ (- heightmap.resolution 1) chunks)]
+            (do-nested xchunk ychunk chunks
+              (let [left-x (* chunk-width xchunk)
+                    right-x (+ left-x chunk-width)
+                    bottom-y (* chunk-width ychunk)
+                    top-y (+ bottom-y chunk-width)]
+                    (mpd-displace heightmap
+                                  left-x right-x bottom-y top-y
+                                  spread))))
+          (recur (+ 1 iter) (* spread 0.5))))
+      (normalize heightmap))
+
+That's a lot to take in.  Let's break it down:
+
+    :::clojure
+    (defn midpoint-displacement [heightmap]
+      (mpd-init-corners heightmap)
+      (loop [iter 0
+             spread 0.3]
+        (when (< iter heightmap.exponent)
+          ; Process the chunks at this iteration
+          (recur (+ 1 iter) (* spread 0.5))))
+      (normalize heightmap))
+
+We initialize the corners at the beginning and normalize the heightmap at the
+end.  Then we loop a number of times equal to the exponent we used to make the
+heightmap, as described above.  Each time through the loop we increment `iter`
+and cut the `spread` for those points in half.
+
+For each pass, we figure out what we're going to need to do:
+
+    :::clojure
+    (let [chunks (Math.pow 2 iter)
+          chunk-width (/ (- heightmap.resolution 1) chunks)]
+      ; Actually do it...
+      )
+
+Let's make a quick "nested for loop" syntax.  It'll make things easier to read
+in the main function and we'll need it for later algorithms too:
+
+    :::clojure
+    (defmacro do-nested [xname yname width & body]
+      (let [iterations (gensym)]
+        `(let [~iterations ~width]
+           (do-times ~xname ~iterations
+             (do-times ~yname ~iterations
+               ~@body)))))
+
+This lets us say something like `(do-nested x y 5 (console.log [x y]))` to mean:
+
+    :::javascript
+    for (x = 0; x < 5; x++) {
+        for (y = 0; y < 5; y++) {
+            console.log([x, y]);
+        }
+    }
+
+And now we can see how we process the chunks:
+
+    :::clojure
+    (let [chunks (Math.pow 2 iter)
+          chunk-width (/ (- heightmap.resolution 1) chunks)]
+      (do-nested xchunk ychunk chunks
+        (let [left-x (* chunk-width xchunk)
+              right-x (+ left-x chunk-width)
+              bottom-y (* chunk-width ychunk)
+              top-y (+ bottom-y chunk-width)]
+              (mpd-displace heightmap
+                            left-x right-x bottom-y top-y
+                            spread))))
+
+We loop over the indices of the chunks, calculate the bounds for each one, and
+displace it.  Simple enough, but a bit fiddly to get right.  And now we've
+finished displacing all the points:
+
+<div id="demo-mpd-4" class="threejs"></div>
+
+## Result
+
+Now that we've got a working algorithm we can play around with the values and
+see what effect they have on the resulting terrain.
+
+**Warning**: don't set the exponent higher than 8 unless you want to crash this
+browser tab.  An exponent of `8` results in a heightmap with `66049` elements.
+Going to `9` is `263169`, which most browsers seem to... dislike.
+
+<div id="demo-final" class="threejs"></div>
+<div id="demo-final-controls">
+    <label>Exponent
+        <input type="number" id="input-exponent" value="5"></input>

+    <label>Spread Reduction Constant
+        <input type="number" id="input-spread-reduction" value="0.5"></input>
+    </label>
+</div>
+
+And that's it, we've grown some mountains!
+
+Now that we've got some of the boilerplate down I'm planning on doing a couple
+more posts like this looking at other noise algorithms, and maybe some erosion
+algorithms to simulate weathering.  Let me know if you've got any specific
+requests!
