I started using material maker recently, it's an open source program for making PBR textures

it's a much nicer workflow for my pixel art style than the krita filter layers I was using before, although it does crash a lot

I've been out of motivation on my godot project for a while, but today I got a foothold on it, converting star rendering to use compute shaders + CompositorEffect

I'm going to try a different way to fix the issues that I got stuck on before (unrelated to star rendering)

I worked on rink this weekend, I'm hoping to get v0.9 out soon if I can, but there are a few big annoying tasks left to do

I've been making a program that runs 3D cellular automata on the GPU using compute shaders, and renders using voxel raymarching

I can run 512x512x512 volumes in realtime on my PC

Ruleset is 1-3/1,4-5/5/N A lot of different lines scuttling about, covering the entire screen in complete chaos. There are colors in a gradient from yellow to purple. The ruleset is 4/4/5/M

Whoa.

That's a sprite, an elusive, high-altitude electrical discharge from a thundercloud photographed by NASA astronaut Nichole Ayers from the ISS earlier today.

With reported sightings going back more than a century, this phenomenon was first photographed in 1989.

Geology Murder

Comic. [two people in labcoats look at body pierced with blade draped over bench] PERSON 1: We found him lying uncomformably on the lab bench. I wonder if the iron-rich intrusion in his back is related. PERSON 2 with ponytail: It could be clastic. Maybe a rift opened in his body, and the intrusive material later fell into the hole.

I started making a procedural planetary system generator, starting from a raw list of elemental abundances + a bunch of formulas for various minerals

it's still pretty buggy but it's really cool to me that it's working at all

traveling so fast that the leftover light from the birth of the universe glows red hot
a ship traveling at 0.99981 c, in a dark void with a bright red light in front of it the ship slowed down to 0.9932 c, the red glow is fading away and the milky way is visible as a ring in front of the ship the ship has slowed to 0.84 c, things are mostly back to normal, although stars are still red- and blue-shifted

I added an intercept planner and now it's much easier to get to places without overshooting by 400 km/s

it automatically activates when your closest approach to the selected object is inside its hill sphere (the area where orbiting it is possible basically)
screenshot of the game, showing venus and the sun in the foreground, venus is selected and the info panel is showing it on the left at the bottom of the screen there is the text: INTERCEPT TRAJECTORY closest approach: 97.14 km time remaining: 10.25 min distance remaining: 0.61 au braking burn needed: 121.45 m/s² same text but zoomed in

antialiased 3d line rendering in godot, with a convenient API

I worked on my project this weekend, I've mostly been refactoring stuff, but I did add some nicer UIs
search UI showing nearby stars sorted by distance, lots of "Gaia DR3 1234" and "HD 1234" a view showing earth orbiting the sun, with a line showing the orbital path a nicely organized info panel on the left showing the objects in the sol system, and the properties of earth

I accidentally made the distance between stars just a little bit too large and everything clamped to the maximum size of a 64bit integer

the box edges look cool

I tried clamping the position to a sphere to see what that would look like too
screenshot from my project, showing a view in deep space of many stars however, many of the stars are bunching up along lines and planes where they would have exceeded the size of a huge box dozens of parsecs across the box edges are super bright because there are a lot of stars bunched up there there's also a bunch of random debug text on screen similar to before, but showing the stars bunching up along the surface of a huge sphere

i turned it into a drawing

in the year 58,515 an interstellar ship tears through space at 99.9999% lightspeed, travelling to some far away place. the extremely blueshifted light is enough to heat its exotic hull to the point of incandescence

doing a big refactor of my project so that I can actually start working on game systems (a lot of the current code is a mess)

I'm using data oriented design (for perf + for fun), which means lots of schemas

I just got done with orbits & stars:
a data schema for the tables: barycenters, orbits, celestials, stars, and systems. most of them are keyed on a `celestial_id` as the primary key, except for the orbits table, which is keyed on a `child_id` and `parent_id` (which are both celestial_id's) this is just a markdown doc but it's too big to paste as alt text a test scene showing a bunch of lines connecting stars in the hyades cluster together, one of them is selected, showing this info: star #059232 name : Theta Tauri Ab gaia edr3 : 3312744219988782720 position : -42.57 -0.26 -17.21 distance : 2.53 pc temperature : 6773 K abs mag : 0.07 luminosity : 73.790423 is hyades : yes white dwarf : no

I've spent so many hours trying to understand how trees work

I tried different tree creator programs, none worked the way I needed, so I started writing my own that works at runtime (currently <3ms to generate this tree)

I also painted the leaf bunch and bark texture
procedurally generated tree that doesn't really correspond to any real life tree species, just the generic idea of "Tree" some of my older lollipop trees are visible in the background

December 20, 2004 saw the release of Doukutsu Monogatari, AKA Cave Story, a free game that was quickly translated into English and became the talk of the Internet. It's hard to estimate the impact it had on the indie scene and on the resurgence of 2D outside handheld consoles.

a neutron star in the year 120 trillion; in this future neutron stars have all cooled to only a few degrees above background temperatures, but they are still incredibly dense. these objects are very smooth and shiny, with splotches of dust from trillions of years of impacts

#b3d
Render of a cooled-off neutron star against a backdrop of a few dim stars and dim red clouds of gas and stuff. The star's mass bends the light around it like you'd see with a black hole. Exposure has been boosted a lot in this render to make anything visible. Render of the neutron star itself with no lensing effect and a lamp shining on it; it's surface is dark and reflective, with scratches and marks dotting its surface. The star exhibits a kind of irridencense like you'd see with an opal.
