It's really fun to explore fractals this way tdhooper.github.io/offline-shad...

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

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

Finally we just need to scale exponentially instead of linearly

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

We can try linearly interpolating from one transform to the next, it loops, but it's not continuous

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

Which we use to tile the face with hexagons, I'm using a variation of this technique from Matt Zucker www.shadertoy.com/view/4d2GzV, it gives you the closest hexagon centers in 2D, which I then project onto the face in 3D by reversing the steps I used to make the uv-map

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

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

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)
