If you've ever played games like Minecraft or No Man's Sky, you've seen procedurally generated terrain. An infinite array of rivers, mountains, and trees can be generated from simple mathematical formulas.
Procedurally Generated Trees
If you're googling the word procedural right now, we aren't talking about in the sense of procedural law or whathaveyou. We're talking about Procedural Generation. In Minecraft for example, when you start a new game, all of the terrain is procedurally generated. No one sat down and modeled the mountains, lakes, and rivers etc.
They were generated algorithmically. In this Instructable my first one by the way I'm going to teach you how to generate a fractal tree from a mathematical " seed " using OpenSCAD. OpenSCAD is a programming language that allows you to generate 3D models using code rather than sculpting or modeling them by hand.
Then I'm going to show you how to make the code customizable, and publish it to Thingiverse as a Customizer so that everyone can "grow" their own unique tree.
Customizer is an app from Thingiverse that allows everyday users to plug in their own variables, such as the seed, and run your code to generate an object, directly through the website. Last, you'll print out your tree so that you can use it in your next model car, train, architectural model, or diorama project.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Our fractal tree is going to use a concept called recursion. Recursion basically means a function calls itself, over and over again, until a stop condition is met.
One common example of a recursive algorithm is calculating the Fibonacci sequence. The Fibonacci sequence goes 0, 1, 1, 2, 3, 5, 8, The first two elements are 0 and 1, and then each element after that is the sum of the last two elements. So lets say we want to find the fifth element, Fib 5 calls Fib 4 and Fib 3and so on in that fashion until Fib 0 or Fib 1 get called. This is the "stop condition" in which it just returns 0 or 1 instead of calling Fib again.
OpenSCAD uses Modules, which are similar to functions or methods, but are compiled in a different way. In traditional programming, the compiler turns your code into a set of instructions for the computer to execute. When you write a C program, for example, that calculates the first few elements of the Fibonacci sequence, it compiles down to the same size as one that calculates the first million elements of the sequence.Use arrow keys to navigate slideshow, and press F11 for fullscreen Output: six images for use as cube map six images representing normal map.
Data Representation Sphere is represented as 6 square arrays of 3d vectors Imagine a cube overinflated until it is a sphere. Each element in the array contains a 3d vector that represents the terrain elevation at a particular point on the sphere. Recursively add "bumps" Start with sphere represented by 6 square arrays of normalized vectors Choose radius and location for bump Marsaglia rejection method Use 0.Über free mp3 s
Modulate bumps with real terrain data Each bump has a vector defining its position on the surface of the sphere Compute quaternion to rotate bump to "front and center" For each point within the "bump", apply this quaternion Then the x,y components can be used directly after scaling and offsetting to index terrain data.
Procedural Generation of Earth-like Planets Use arrow keys to navigate slideshow, and press F11 for fullscreen Output: six images for use as cube map six images representing normal map. Since 0. Next, craters are optionally added. Similar to "bumps" except: Different profile No terrain sampling Still needs some work. Abusing cosine some more Next, heightmap data is painted into 6 temporary images Height is scaled into the range 0 -and RGB channels are set to height.
This produces grayscale images where intensity is proportional to altitude. From the heightmap, normal map images can be calculated. Simply mapping altitude to colors directly is unsatisfactory For each vertex, an fBm noise value is calculated Using altitude for one axis, and this fBm noise value for the 2nd axis, we can index into 2D source images for land and water for above and below sea-level cases, respectively.
This gets us something like this: What about clouds? Clouds are hard fBm noise, simplex noise, Perlin noise by themselves are not satisfactory Need to look into Worley noise How to generate something like what is below?
I have no good idea. Using no sea-level, craters, and different terrain sample images, we can make moon-like planets: Some cratersInstead of focusing on making something that is realistic or fully procedurally generated I wanted something that could create plants or other things in a recognizable stylized way from a simple set of rules and shapes.
The scene above was an attempt to recreate the trees from this short scene from the movie Coraline:. It's basically just stringing a few simple Bezier curves together and generating a cylinder mesh along those paths. The leaves are just flat, colored planes here. There's quite a bit more going on under the hood than shown here, so I hope to add more scenes. After watching the great introduction to grammar systems by Rachel Hwang in this years procjam talks I'm thinking that might be a logical next step.

Leave a comment Log in with itch.Abstract We will present a real-time method for procedurally generating huge planetary landscapes with continuous level of detail.Cnc plotter arduino code
This approach enables us to produce interesting planets with a small or non existing pre-generated dataset, which in turn could be used to visualize an endless number of different planets. Where previous work in landscape generation have generally been purely procedural or purely design, we have devised a method which allows for a seamless integration of design into the computer generated world.
Another novelty is the decoupling of the mesh optimization from the rendering. While a high frame-rate is a requirement for fast and smooth animation, the mesh optimization can run in the background at a slower pace. We have implemented a system with different update frequencies for rendering and mesh optimization, to let us prioritize the different tasks, and to distribute the workload on multiple processors.
A method to generate natural looking river systems in the procedural generated terrain is explored and implemented. While we found that actual real-time procedural river generation was very difficult, one could combine a fast preprocessing step, with correct river flow calculations, which could later be placed inside the terrain.

Cloth simulation.Species in No Man's Sky are procedurally-generated, and can be affected by a number of factors such as the player, surrounding area, environment, or location. Plant lifeforms can range from the purple bio-luminescent mushrooms showcased on Sayallto the green grass and trees of New Ventuwhile creatures include both the towering Daplokarus and the small fish-like Ictaloris Alus.
All flora and fauna in the game is mathematically generated using a series of algorithms, rather than being individually designed. Fauna can be fed to befriend them. The food needed to befriend an animal varies by species, but is usually easy to obtain on their native planet. Befriended animals have a smiley-face icon. Befriended fauna will occasionally give you Faecium or point out interesting features. Fauna can also be killed to obtain Morditeand can be scanned after they've been killed.
Hostile, aggressive fauna that are near the player are indicated by a red paw icon; they will attack and try to kill the player when in range.
Most flora can be mined to harvest Carbon and other resources. Scanning flora and rocks can reveal their secondary minable resources. Brightly-colored flowers can often be harvested to gain a variety of resources. Some flora is hostile, damaging players that approach. There are five sentient species that can be encountered throughout the universe, each with distinct languages, lore, and technology aside of the Anomaly.
Most sentient species can be found at space stations and points of interest inside buildings except for the Anomaly. Each of the three main races Gek, Korvax, Vy'keen have a reputation system with several ranks.
Helping the common species or successfully interacting with their monuments provides reputation increases and rewards such as blueprintsmoney, locations of interest, vocabulary wordsand access to services such as shield recharges. The player can also obtain different multi-tools and ships from interactions with other sentient species. There are 23 genera or types of fauna in the game. For records on the largest and smallest fauna in the game, see Fauna Hall of Fame.
For a list of discovered species, refer to the Species category. For a list of pre-release species, refer to the Pre-release species page. Most flora-existent planets have variations of the major types, either in size, shapes, colours or details.
Many have variations of the same type on the same planet. It has been stated by Sean Murray that there will be carnivorous plants on some of the planets. In a December interview with Game Informer Magazine, Sean Murraythe founder of Hello Gamesrevealed several images of procedurally-generated animals giving an indication of what might appear in the released version of the game.

Category : Species. Navigation menu Namespaces Page Discussion.Procedurally Generated Maps were introduced in This feature allows players to let the game generate a random map, based on parameters or a seed. NOTE: However unfortunately it is severely underused as the debut trailer it was shown in was very vague and after its release they never supported the mode again so do beware of bugs and be prepared for crashes when you attempt to generate a map.
Other important key things to note are there are no options to choose which creatures you do and dont want in the maps you create, no obelisks or bosses even in the pre-existing custom mapsand when trying to make your map there is no mini map in the generation options screen to show what your changing so making your map can be very difficult, so it's uses are very limited due to the lack of support from wildcard post-launch.
The seed is the base of a procedurally generated ARK. Each seed will create an ARK which can be remade by using the same seed and other settings. This way players can share their favorite maps with the world.
Seeds can only be up to three digit numbers. Non-numerical seeds default to zero, as do seeds larger than The size of the land area of your ARK.
If this value is too high it won't have much water between the border of the map and the land of your ARK. At the maximum value, 50, there will be no ocean biome in your ARK. Water frequency determines how often the map alternates between land and water. This has no effect on the ocean between the edge of your landmass and the map border. With a low water frequency, you end up with a few or one giant lakes.
With a high water frequency, you end up with a lot of small puddles or rivers. The higher this number, the more mountains you have. Setting this too high can create impassable terrain. The Mountain Slope setting will change the steepness of a mountain.
A lower number will generate steeper mountains that are harder to walk on than mountains generated by a higher number.
This number only goes from 0 to 2. This setting will set the maximum height of mountains. When using 1 as value the maximum height of a mountain will be about the same of the height of mountains on The Island.Grass is generally considered backdrop and not part of the scannable flora. On many toxic and radioactive planets, small mushrooms may take the place of grass and are also unscannable.
The type of plant life depends upon what kind of planet the flora is living on. Most species can be mined using the Multi-tool for Carbon and some species can be picked for special elements. The scanner will indicate which resource you will get. For a list of plants containing special elements see resource.
Flora can be renamed and uploaded for Nanite Clusters. There is no indication how many different flora species are on a planet and scanning them does not count towards completing zoology efforts. Some flora is hazardous and will hurt the player if they step too close. The properties of the plant are procedurally generated terms and don't have an effect on the gameplay, aside from Primary Element and Secondary Element.
Oxygen and Sodium rich plants can be scanned; just do it before collecting the resources. This is the main element that the plant will give the player when mined.
Procedurally Generating Trees
This element is usually Carbon. Primary Element cannot be viewed in a species's collection logs. Some plants will give the player a small amount of a second element when mined.
Secondary Element cannot be viewed in a species's collection logs. Most flora-existent planets have variations of the major types, either in size, shapes, colours or details. Many have variations of the same type on the same planet. Sign In. From No Man's Sky Wiki. Jump to: navigationsearch. The subject of this article is from the Visions update.
