  • I got my home server (Lenovo thinkcentre, i7 6700) for $30 minus ram or storage at my local university surplus store a few years ago, and I have no regrets. Added a 256gb sata SSD, 16 gb RAM, 8tb HDD all refurbished for like +$150 when that was still cheap.

  • Makes sense, for naive, completely diffuse lighting (not reflective) the result is just the sum of base color * light visiblity * cos(angle between surface and light) for every light

    And then for light bounces just repeat that many times, but considering every surface as a light

    In the general case, for a more complicated material, the resulting brightness on a surface can be pretty much any arbitrary function of wavelength, the angle the light comes in, and the angle of the observer (called a BRDF). As long as it's not putting out more light than it's getting in, it's probably possible. These functions can get especially complicated when there's multiple thin layers, imagine a brushed metal surface with a layer of oxidization, a clear coating, some dirt, and some dust. Even for a single position on the surface, each of those reacts so differently to different input and output angles that no simple functions will represent the surface well. For CGI in films, they usually will layer many simpler BRDFs together, but that's slow for games, which usually try to approximate surfaces in a single one.

  • Yes, it's a common brand.

    In the United States, pudding means a sweet, milk-based dessert similar in consistency to egg-based custards, instant custards or a mousse, often commercially set using cornstarch, gelatin or similar coagulating agent. These puddings are known in some Commonwealth countries as custards (or curds) if they are egg-thickened, as blancmange if starch-thickened, and as jelly if gelatin-based. Pudding in America may also refer to other dishes such as bread pudding and rice pudding, although typically these names derive from their origin as British dishes.

    Steam Controller page updated: $99 USD, releases May 4th

  • If you are playing games where trackpads are useful, there's not really another option, so it's automatically a good value. I know my steam deck experience would have been a whole lot worse without those, and I would probably never consider a gaming handheld without them. But for the gaming I do with an xbox controller, I currently just use it for some video games at my computer (where I have access to a mouse anyways), and maybe split screen with family. I think my Gamesir Cyclone 2 controller (at half the price) is an unambiguously better deal for that, in the premium controller space. If I were using it mostly for couch gaming, that might put the Steam controller in a better position, or if I were mostly playing games that support whatever haptic trigger things Sony has, that controller might be in a better position.

    One of the other more unique features is the tracking in the Steam Frame. It would be cool if they could standardize that sort of thing so it would work with other headsets. I wonder if they've considered that.

  • They can make it illegal to sell certain types of hardware to consumers that allows you to install your own operating system. Of course, there is still virtualization. You can run Linux in a web browser nowadays (badly, but if there was a reason to improve it I'm sure it would be done)

  • As an amateur computer graphics person, the best way to draw accurate stars is to just pre render it onto a cubemap. But if you really need that subpixel worth of parallax to be completely accurate for every star, there are a couple ways I can think of off of the top of my head. With any you'd want to make sure you only store position, size, and color, since stars are all spheres anyways. With effort, you can be very flexible with how these are stored. (4 bits color temperature, 4 bits size, 3*32 bits coordinates maybe)

    • splat each star into the screen texture with atomics
    • some sort of tiled software rasterization thing, like in Gaussian Splatting

    Worse ideas:

    • instanced hardware rasterization
    • ray tracing

    This is not that well suited to most usual rendering techniques, because most stars are probably going to be much smaller than a pixel. Ray tracing would mean you need to just hit every star by chance (or artificially increase star size and then deal with having tons of transparency), hardware rasterization is basically the same and additionally is inefficient with small triangles. I guess you could just live with only hitting stars by chance and throw TAA at it, there's enough stars that it doesn't matter if you miss some. That would react badly to parallax though and defeats the purpose of rendering every star in the first place.

    It's much more efficient to do a manual splatting thing, where for each star you look at what pixel(s) it will be in. You can also group stars together to cull out of view stars more efficiently. Subpixel occlusion will be wrong, but it probably doesn't matter.

    This is all just for the viewport, though. Presumably there are other objects in the game besides stars, which need to have reflections on them of the stars. Then that becomes an entirely different problem.

    The real answer though is that you wouldn't try to render all of the stars, even if you want parallax. Maybe some of the closer and larger ones as actual geometry, simplify a ton of stuff in the background, render things as volumes or 2d billboards, have a cubemap for the far distance, etc

    Edit: also ofc this presumes you know the position, scale, temperature of every star

    I also like the idea of baking all of the stars into a volume in spherical coordinates, centered around the origin

  • If it doesn't come with the 3d printer, a pair of flush cutters is insanely useful. Just be careful with them, especially if you have a cheap pair. Probably wear eye protection.

    If you think you would find them useful, there are also filaments at different levels of softness, bounciness, and foaming variants of those. Particularly useful for the soft ones as you can get different levels of softness by changing printing temperature. For any it helps to decrease weight.

    For 3D modeling software, Fusion is good but annoying to obtain, Onshape is good but has a non-commercial license for the free version (and makes all of your files public), Freecad is FOSS, decent but not quite as good, Blender is good for detailed or sculpted things that are more art-y (although it's often very difficult to achieve certain shapes that are easy in actual CAD software)

    My modelling advice is to keep in mind where supports will go, what places can be bridged, what details the printer can achieve, what axis the vertical should go on (for strength)
