  • The only code with timezones should be the bit squishy meat bags touch. Everything’s is should be UNIX time. Or it you are unfortunate enough to be on Windows, NT time.

    Some unfortunate programmers already have to deal with the speed of time not being a constant. In a distant future, timestamps might always have a universal position (and speed), and is that much different from timezones?

    Or we find some way of removing time distortion of physics. Find the universe’s real systick. 😃









  • That’s pretty neat. Game streaming isn’t that different. It basically loads the adjacent scene blocks ready for you to wonder in that direction. Some load in LOD (Level Of Detail) versions of the scene blocks so you can see into the distance. The further away, the lower the LOD of course. Also, you shouldn’t really keep the same origin, or you will hit the distort geometry issue. Have the origin as the centre of tha current block.


  • I just gave up fighting. There is no system that is going to both fast and infinitely precision.

    So long ago I worked in a game middleware company. One of the most common problems was skinning in local space vs global space. We kept having customers try and have global skinning and massive worlds, then upset by geometry distortion when miles away from the origin.

    As a programmer who grew up without a FPU (Archimedes/Acorn), I have never liked float. But I thought this war had been lost a long time ago. Floats are everywhere. I’ve not done graphics for a bit, but I never saw a graphics card that took any form of fixed point. All geometry you load in is in floats. The shaders all work in floats.

    Briefly ARM MCU work was non-float, but loads of those have float support now.

    I mean you can tell good low level programmers because of how they feel about floats. But the battle does seam lost. There is lots of bit of technology that has taken turns I don’t like. Sometimes the market/bazaar has spoken and it’s wrong, but you still have to grudgingly go with it or everything is too difficult.
