Roninkoi boosted

I've been working on a new series of 3D fractal shapes intended for 3D printing and tabletop gaming. These are shapes that remind me of natural (or alien) terrain.

I find and extract the 3D meshes using Mandelbulb 3D and process them in ZBrush.

Most of these I've already test-printed, but I still need decent photos of the results.

Maybe I should do a small

Hello everyone! I'm Ron(i) and go by Roninkoi in most places. As a kid I started off making games for competitions such as , but these days I'm more into the technical side of things. Graphics programming and is my main interest, especially and . IRL I'm a computational grad student working as a part-time code monkey

My Emacs pinky is flaring up again, so trying to use the right Ctrl key more. Muscle memory is dang hard to overcome!

This comes from the matrix
$$L = \begin{pmatrix} V(1) & 1 & 0 & \cdots & 0 & 1 \\ 1 & V(2) & 1 & & & 0 \\ 0 & 1 & V(3) & 1 & & \vdots \\ \vdots & & & \ddots & & 0 \\ 0 & & & 1 & V(q-1) & 1 \\ 1 & 0 & \cdots & 0 & 1 & V(q) \end{pmatrix},$$
where $$V(k) = 2 \cos(2 \pi k p/q)$$ for integer p and q.

Hofstadter's butterfly is a fractal arising from non-interacting electrons in a magnetic field. We can draw it by computing the eigenvalues of the system's Hamiltonian and plotting values of the Lyapunov exponent. Here's a shader that does just that! shadertoy.com/view/7s2XRt
