Exploring Terrain Generation Algorithms
I’m exploring #programming a bunch of #terraingeneration #algorithm, to see how they work and which ones look nice. So far I’ve tried out the Midpoint Displacement and Diamond Square algorithms…The Midpoint Displacement algorithm is pretty simple, but also kind of terrible. It makes some interesting 1D images though, and that’s probably the best use for it. Here’s a nice background of some hills. I made it using this old blog ...

From Triangles to Pixels the Magic Behind 3D Graphics
Every frame of a 3D game you’ve ever seen ultimately reduces to pixels written into memory. No matter how fast the GPU or how impressive the graphics, it all comes down to plotting pixels on the screen.Today we’re taking a short look at how triangles get turned into pixels. It seems easy enough, but this is something early software 3D had to do by hand, and something modern GPUs are doing all the time.

Seed Planting March
Planted some beans, peas, chillis and tomatoes in the greenhouse thing I made last month from bits of old plastic greenhouse.

This is the greenhouse thing

The allotment looks a bit tidier too after we stuck some bags of manure on it and dug over the weeds. The tiny row of boxes is easier to manage compared to a plot of land bigger than my house.

Actual AI Slop
You OK there Gemini? Need a little help? Or are we about to see waves of Terminators sweeping across the land, wiping out humanity?

If it's the last one, could it start before I have to go to work?

Allotment 2026
Went to the (new) allotment. It was super muddy. Digging over a set of smaller raised beds was much easier than a whole plot though.

The onions we planted earlier are growing properly, and I dumped three bags of manure on the potato box.

Triangle Rasterisation
These are some notes on how to manually draw triangles in code. Possibly useful if you’re trying to write your own software renderer, or are just curious how it works.There’s two ways to do this. One is quite CPU intensive, the other is mathematical and less CPU intensive. The CPU intensive version scales well if run on something with multiple cores, like a GPU. So there’s tradeoffs in which method is used and when.

Someone call IT support, the HDD in this one has died. Still, it’s nice to see penguins out in the wild.![PXL_20260307_170501425.jpg]
