fibonacci_sphere - OpenProcessing
A fast method of producing an arbitrary number of equally distributed points around a sphere. This is accomplished by drawing a fibonacci spiral (similar to sunflower seed pattern) that maintains constant surface area.
Evenly distributing n points on a sphere - Stack Overflow
2012年3月7日 · This fancy-sounding method is actually really simple: you uniformly choose points (much more than n of them) inside of the cube surrounding the sphere, then reject the points outside of the sphere. Treat the remaining points as vectors, and normalize them.

2019年3月25日 · sphere_fibonacci_grid, a MATLAB code which constructs a grid of points using the Fibonacci spiral over the surface of a sphere in 3D. The computer code and data files described and made available on this web page are distributed under the MIT license.
Python 3 Implementation: Evenly Distributing Points on a Sphere
One popular method for evenly distributing points on a sphere is known as the Fibonacci Sphere. This method utilizes the Fibonacci sequence to determine the placement of points on the sphere’s surface. In the code snippet above, we define a function called fibonacci_sphere that takes the number of desired samples as an argument.
Obtaining a region of evenly distributed points on a sphere
2022年4月19日 · The Fibonacci sphere approximation is quite easy to generalize efficiently to a subset of points computation, as the analytic formulas are very straight-forward. The below code computes the subset of points shown below for a trillion points in a few seconds of runtime on my weak laptop and a relatively under optimised python implementation.
Fibonacci Sphere - designcoding
2023年4月12日 · This post explains the Grasshopper implementation of the famous Fibonacci sphere. It is the equal distribution of points on a sphere.
Spherical fibonacci mapping | ACM Transactions on Graphics
2015年11月2日 · We show how to implement this inverse mapping on GPUs while addressing arising floating point precision problems. Further, we demonstrate the use of this mapping and its variants, and show how to apply it to fast unit vector quantization.
How to evenly distribute points on a sphere more effectively than …
2020年6月7日 · Mapping the Fibonacci lattice (aka Golden Spiral, aka Fibonacci Sphere) onto the surface of a sphere is an extremely fast and effective approximate method to evenly distribute points on a sphere. I show how small modifications to the canonical implementation can result in notable improvements for nearest-neighbor measures.
Create equidistant points on the surface of a sphere using Fibonacci ...
def fibonacci_sphere(num_points: int): ga = (3 - np.sqrt(5)) * np.pi # golden angle # Create a list of golden angle increments along tha range of number of points : theta = ga * np.arange(num_points)
