I consider myself a pretty good Mathematica programmer, but I'm always looking out for ways to either improve my way of doing things in Mathematica, or to see if there's something nifty that I haven't ...

I'm generating some 3D models of planetary nebulae and supernova remnants for Celestia, a free OpenGL astronomy software. Currently, I know how to do it with random points inside a spherical shell. ...

I'd like to generate some visually-pleasing animations of clouds, fog or smoke with Mathematica. My idea of "visually-pleasing" is along the lines of one of the images on the Wikipedia article for ...

Upshot I am interested in identifying critical points of a 3D field/cubes (maxima, minima, tube-like and wall-like saddle points) and 2D field/image (maxima, minima, saddle points). I.e. the ...

I stumbled upon this stunning image here. Author responded to me with the p5.js JavaScript library code: Don't know if this help, but this the code for a single bug 😅 (cx,cy are the coordinates in ...

Context A couple of years ago I posted this question for an efficient code to generate an n-D Gaussian random field (sometimes called processes in other fields of research), which has applications in ...

Context As a follow up of this question and that answer, I would like to identify the special lines separating 3D watersheds. These are useful in the context of astronomy to identify the ...

Context I would like to compute the MorphologicalEulerNumber of 3D GaussianRandomField as a function of height above a given threshold. Attempt I proceed as follows:...

Perhaps a stupid question but I am used to that. This is a perfect smooth surface with circle contour. How can I add some small noise to it to have an actual moutain look with not so smooth contours ...

Context As a follow up of this question, I would like to predict the connectivity of the so-called cosmic web in arbitrary dimensions. The connectivity $\kappa$ is defined as the number of ridges ...

I'm trying to produce turbulent swirling effects in an image using Curl Noise. The idea is you start off with some random field (usually Perlin noise) and use the curl of this field to displace the ...

Question Is it possible to extend the function ItoProcess so that it takes correlated noise? I.e would like to be able to write ...

Context I am trying to solve a stochastic equation corresponding to Vector resonant relaxation (the way orbital planes of stars diffuse near the galactic center, see below). Setup Within the context ...

Context I am interested in connecting neighboring points in 2/3D as list of segments. I am guessing this is something within the reach of graph theory, which is well implemented in mathematica. ...

I need to generate two correlated gaussian random fields. As far as I know, this question and this other provides the means to generate a single autocorrelated process. However, I am clueless about ...
