simplex noiseの例文

• Later developments were Simplex noise and OpenSimplex noise.
• Simplex noise has the same purpose, but uses a simpler space-filling grid.
• Simplex noise is often faster with fewer artifacts, though an older function called Perlin noise may be used as well.
• It is conceptually different from, and often confused with gradient noise, examples of which are Perlin noise and Simplex noise.
• Simplex noise is useful for computer graphics applications, where noise is usually computed over 2, 3, 4 or possibly 5 dimensions.
• Simplex noise alleviates some of the problems with Perlin's " classic noise ", among them computational complexity and visually-significant directional artifacts.
• Perlin did not apply for any patents on the algorithm, but in 2001 he was granted a patent for the use of 3D + implementations of simplex noise for texture synthesis.
• For many applications, multiple octaves of this noise can be generated and then summed together, just as can be done with Perlin noise and Simplex noise, in order to create a form of fractal noise.
• "' OpenSimplex noise "'is an n-dimensional gradient noise function that was developed in order to overcome the patent-related issues surrounding Simplex noise, while continuing to also avoid the visually-significant directional artifacts characteristic of Perlin noise.
