Perlin Noise是一种用于生成自然风格纹理和仿真自然现象的算法。它由Ken Perlin在1985年提出,后来在Srinivasan、Basdogan和Ho的研究中得到了进一步的发展。这种噪声算法通过在网格中分布的随机向量来创建连续的、具有随机性质的函数。在3D空间中,Perlin Noise可以用于创建山脉、云层、火焰等各种自然图案,并被广泛应用于...
似乎非常典型地使用3D Perlin噪声函数的结果作为密度测试，如果它大于0，则表示陆地，小于或等于0表示空气...
In this study, the Perlin Noise algorithm was used to create a map for the game that was built. Perlin Noise created realistic visuals and sound effects in games. Besides that, it was very efficient and easy to use. This research was made with the aim of designing and building an ...

To create a Perlin noise function, you will need two things, a Noise Function, and an Interpolation Function. 为了创建一个柏林噪声函数,我们需要两个东西,一个噪声函数和一个插值函数。 Introduction To Noise Functions 噪声函数介绍 A noise function is essentially a seeded random number generator. It ...
The Perlin noise technique is very similar to the value noise algorithm though rather than selecting random values at integer positions along the line, we choose "gradients". Gradients can be seen as "tangents" to the 1D noise function at the lattice points. As you can see in Figures 7 an...
