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

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

I was struggling for hours yesterday to get this to work, but thankfully there was this super helpful forum thread from 2011:

www.gamedev.net/forums/topic...
STufaro (Author) 183 stars December 28, 2011 04:41 PM Well, after a little bit of struggling yesterday I've come up with a buggy, but somewhat-working, implementation. My basic steps are as follows: Get the vector of the line: lineDirection = (lineStart - lineEnd) Find our soon-to-be constructed quad's normal as: quadNormal = cameraPosition - lineMidpoint Where lineMidpoint = ((lineStart + lineEnd) / 2). I reason this should be the quad's normal since the quad will always be facing the camera, like a billboard. Get the direction along which we should extrude vertices from our line, which is the cross product of lineDirection and quadNormal: extrudeDirection = Vector3.Cross(lineDirection, quadNormal) Normalize extrudeDirection. Get the W of lineStart and lineEnd by transforming them by the viewMatrix * projectionMatrix. wStart = (Vector3.Transform(lineStart, viewMatrix * projectionMatrix)).W wEnd = (Vector3.Transform(lineEnd, viewMatrix * projectionMatrix)).W Extrude vertices from the line along the extrudeDirection vector, in some multiple of the W. Vector3 startVert1 = lineStart + extrudeDirection * wStart * lineWeight Vector3 startVert2 = lineStart - extrudeDirection * wStart * lineWeight Vector3 endVert1 = lineEnd + extrudeDirection * wEnd * lineWeight Vector3 endVert2 = lineEnd - extrudeDirection * wEnd * lineWeight Connect the vertices to form a quad.

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

I might eventually release this as an open source addon

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

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

the same tree but it's more hd now

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

made a sand texture and then added support for multiple terrain materials (this is the first working version, there's still some bugs to work out)

the water looks a lot nicer when there isn't grass under it

I've been on a quest to render an entire spherical planet in godot, without destroying the framerate on my laptop

I got the terrain LOD working recently, and today I made a water shader
view of the horizon from a high hill, there is grass and square rocks and trees in the foreground, with lakes and mountains and clouds in the background, the sky is daytime with stars and another planet visible view showing shorelines having a stylized white edge on them closeup view of the water with some submerged rocks visible

I made a volumetric clouds shader in godot

it was fun and I learned a few things about ray marching

I made some progress on my godot project, added the start of a scenery/clutter spawning system

I needed to use MultiMesh and direct RenderingServer/PhysicsServer access to avoid destroying fps

everything is still placeholders, I'll have to make a bunch of rocks, plants, and ground textures

I beat factorio space age, it took 137 hours (been playing it since it came out a month ago...)

my most recent playthrough of the base game (v1.1) took 40 hours for context

very cool expansion pack. I liked fulgora a lot

fractal cool S

I saw a meme about a cool S made of cool S's, so I made it into a fractal
the famous "cool S" symbol, but each line segment is replaced with a smaller version of the symbol, recursively

I found out today you can tile a sphere with quads using a rhombic dodecahedron, and made this in blender

doesn't seem better than a cubed sphere in most cases, but it does get some usage, like the HEALPix map projection
