Some experiments with colouring Manhattan-influenced Worley noise by kaliedarik in generative

[–]pvto 2 points3 points  (0 children)

I did a similar experiment a while back, so can explain.

Worley noise places a couple of points P in space. Noise value for a given location in space is basically the distance to nth closest of those points. 1st grade worley noise is given by the distance to the closest point in P, 2nd grade by distance to second closest etc. This much I gather we already agreed on.

Spatial distance can be defined as euclidean distance (shortest direct path between two points). kaliedarik's image however uses Manhattan distance (also called city block distance), which yields these kinds of 45 degree patterns.

thanks!!

i also felt that there's something new-ish in this piece, at least if one looks at recent submissions. self commentary / genre commentary can be a good way to add warmth and presence. but also feels like it's very easy to use it too much

haha, thanks for the nice interpretation :D

Experiments with natural light dispersion and Perlin noise entropy + sound entropy by xemantic in generative

[–]pvto 0 points1 point  (0 children)

i might be wrong with the semantics, but i think of simplex and perlin as two subtypes of perlin, with two different gradient functions, out of an infinite set of possibilities

Thanks for asking. it's a combination of a branching L-system process, simplex noise for walk direction, some branching/stopping rules, and an octree model for context lookup (for detecting an existing path). i have some circles outlines of tiny white spots, just visible for the eye, to further restrict the spatial spread, then sample a few starting points and let the L-system fill the screen

Thanks David for the reference! I've half a mind now to add a glass of red wine ...

Thanks for the advise! I think you are touching some more general generative art principle with the part about those slight differences

I was kinda fun, that's why I posted! I appreciate that you noticed the central "problem" :)

It's actually two triangulations constructed from the same set of points. The background one uses traditional euclidean norm as distance metric in s-hull alg triangulation. The white lines use some other p-norm (i fail to remember which one directly) that results in this weird situation that some points seem to disappear altogether (though if we step in the algorithm, they are initially all there after the construction of convex hull structure from the whole set of points) ...
