The atomic structure of fractals

One of the tedious aspects of modeling SDFs with raw shader code is adjusting the position of objects, so I'm adding transform gizmos into my tool They write changes directly to the shader on disk, so I don't need an external object hierarchy tdhooper.github.io/offline-shad...

This one's from 2020, one again created entirely with a raymarching shader www.youtube.com/watch?v=ACqg... This time I'll talk about seamless camera movement...

Once we've put all that together we can have some fun with it ;) here's the shader used to make these gifs www.shadertoy.com/view/lf3BDr

Notice there is a point that the fractal converges on, if we rotate around that, it looks better but there's still a little jump I've a method for finding this point of convergence here www.shadertoy.com/view/tscBDH

Let's look at the problem in 2D, we want to achieve this, moving from one face to the next in a smooth continuous movement

Let's post some old work with a little behind-the-scenes This loop, Fractal Polycephaly, won the 2019 Revision Demoparty animated GIF competition It's rendered entirely within a raymarching shader, there's no polygonal geometry

Here's a shadertoy with a minimal version of this geodisic tiling method www.shadertoy.com/view/XtKSWc

From these two points, we can construct a little uv-map for the section of the icosahedron face we're near

We can speed things up by just calculating distance to the tile we're near, or even better, just the tile-corner we're near

Before I continue, a primer on ray marching SDFs: While ray marching, you take your current position on the ray, with which query the SDF for the distance to the geometry surface, and step forward along the ray by that distance. Eventually you either converge onto the surface, or shoot past it

The head is a distance field, mostly constructed using metaballs and a lot of smooth-blended CSG primitives, about 500 lines of glsl www.shadertoy.com/view/wlf3WX Here we can see the primitives as they are blended together (Thanks teadrinker for this visualisation www.shadertoy.com/view/tlByzR)

Hi Bluesky! With the sudden closure of Jumpship, I'm looking for a new role I'm looking for anywhere I can make beautiful things with code, my ideal role would be a mix of graphics programming, technical art, and gameplay programming (or anything else interactive)

If you're reading this you're probably familiar with my shaders, you can take a closer look on instagram instagram.com/tdhpr or shadertoy shadertoy.com/user/tdhoope...
