Procedural generation of a constrained landscape

I'd like to implement a procedural generation of a terrain. After a thorough research I came up with a conclusion that it should be implemented with one of the gradient (coherent) noise generation algorithms, for instance Perlin Noise…

Smoothing Land Around Lakes

Sorry if that title isn't very descriptive. Anyway, I am working on something dealing with randomly generating landscapes. I made lakes, but due to how they are make, they often cause straight edges / dropoffs, which aren't desirable. I am trying to…

What ways are there of drawing 3D trees using Java and OpenGL?

I know how to draw basic objects using JOGL or LWJGL to connect to OpenGL. What I would like is something that can generate some kind of geometry for trees, similar to what SpeedTree is famous for. Obviously I don't expect the same quality as…

How can I sample from a complex or compound distribution in Haskell?

I'm trying to generate random masses for hypothetical planets in Haskell. I want to produce these masses by sampling a bi-modal distribution (ideally the superposition of two normal distributions: one corresponding to small planets and one…

Minecraft speed for loading chunks

I am working on a voxel terrain generator. Everything is fine, I have biomes, blocks, etc. What tickles me is the speed of my project in unity. If I run everything on the main thread I can only load and render 1 to 2 chunks without dropping below…

How does one make a point to point "bolt" of lightning using perlin noise or other algorithm?

Every implementation I've come across of perlin noise generation has been for the generation of 2D terrain, etc. I cannot find a decent example of point to point lightning generation anywhere. Are there many other forms of generating 'lightning'? …

Smoothing issue with Diamond-Square algorithm

I am using the diamond-square algorithm to generate random terrain. It works fine except I get these large cone shapes either sticking out of or into the terrain. The problem seems to be that every now and then a point gets set either way too high…

Help with using the perlin noise library libnoise

When I call libnoise's getvalue function with x, y, and z as integers I always get 0 back as a result. Is this normal? When I try 1.25, 0.75, 0.5 as in the tutorial http://libnoise.sourceforge.net/tutorials/tutorial2.html I get the expected result…

Questions on Procedural World Generation - I can't generate more than hilly terrain

I've been trying to generate a 3D Minecraft world with noise maps, but no matter how I overlap sounds, I can't get a noise map that has both flat areas and mountainous areas. So far I tried overlapping different noise maps, with varying results, and…

Algorithm for generating a subway transit map

I would like to draw a transit map which is not based on any real map. Unlike conventional maps, transit maps are usually not geographically accurate—instead they use straight lines and fixed angles, and often illustrate a fixed distance between…
