[QUOTE=Larikang;46759222]But that doesn't work either. You can easily end up planning [i]too much[/i], and when you start implementing it you realize that your design is impractical.

Good programming is about finding the right balance between careful planning and figuring out things as you go.[/QUOTE]

It's also worth mentioning that the code you write for yourself rarely has a set objective and a specification so it's impossible to structure your project so perfectly that anything you want to add later fits in. And adding stuff later is basically all you do anyways...

Man, what you are doing is something I've wanted to do for a LONG time. I'm just starting to learn Unity, and I was thinking of doing something like this but in 2D for that "lel INdie dezigner" feel. (that and the fact I can't do 3d stuff for shit lol)

It's really cool watching this develop. Good on you!

I've got a while to go yet before being as good and pretty much ANYONE in this thread, but I'm hoping it wont take TOO long. :)

After 10 weeks of literally the most amount of work i've ever had to do, its back to fun programming again (PS do not take an uneven module split between terms at uni)

Anyway, hooray! I THINK this might be wavelet noise

[IMG]https://dl.dropboxusercontent.com/u/9317774/wavelet.PNG[/IMG]

Unfortunately the [url=https://en.wikipedia.org/wiki/Wavelet_noise]wikipedia[/url] page is hilarious, and the paper I'm referencing from is not exactly much better.

This is so I can do the cool wavelet upscaling thing for a low resolution navier-stokes gpu simulation, hopefully to generate high frequency noise and simulate very high detail smoke with a very low level of computation

I made a cute little program to fix steam's annoying size 16 chat font they changed to a while back:

Quicker then your mom and dirtier then a $1 hooker.. but it works!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace SteamFix
{
    class Program
    {
        static void Main(string[] args)
        {
            string dir = "C:\\Program Files (x86)\\Steam\\resource\\styles\\steam.styles";
            try
            {
                string text = File.ReadAllText(dir);
                text = text.Replace("font-size=16", "font-size=14");
                File.WriteAllText(dir, text);

                Console.WriteLine("Fonts Fixed! :D");
            }
            catch (FileNotFoundException e)
            {
                Console.WriteLine(e.Message);
                throw;
            }

            Console.ReadLine();
        }
    }
}

Even more assets for the little runnerXborderlandsXcrashbandicoot game, this are the characters in the release version. If things go well we will do more, but for an initial version it should be enough to test the water.

I spent a couple of hours making the necessary improvements to associative carriers so that gender-neutral names would match with either pronoun. I rewrote the algorithm three times, but couldn't get it to work. I finally gave up trying to plot out the logic mentally and drew it on a whiteboard:

[t]http://i.imgur.com/DpjSazL.jpg[/t]

After pausing to cackle wickedly, the above mess was magically transformed into this:

public static bool AssociatesWith(this RantDictionaryEntry a, RantDictionaryEntry b)
        {
            bool aNoneRequired = !a.GetRequiredClasses().Any();
            bool bNoneRequired = !b.GetRequiredClasses().Any();

            if (aNoneRequired && bNoneRequired) return true; // If both have no required classes, pass.

            // One or both have required classes.

            // Remove B optionals from A required.
            var aRequired = a.GetRequiredClasses().Except(b.GetOptionalClasses());
            // Remove A optionals from B required.
            var bRequired = b.GetRequiredClasses().Except(a.GetOptionalClasses());

            // Both should be either empty, or have exactly the same classes.
            return !aRequired.Except(bRequired).Any() && aRequired.Any() == bRequired.Any();
        }

You found an edge case where "Jessie" contains the optional class "female?", which can be fixed by specifying a class filter on the pronoun. Something I need to fix. But the majority of names will provide a correct output.

Yes, but now I only need to press a button on my desktop ;)

Originally I was planning to have it only change the specific size 16 fonts that mattered.

okay the font texture atlas now grows when needed

the growing algorithm kind of sucks since this is what you would get if you originally specified that above size

but whatever it's good enough for now

unless you add too many glyphs

[QUOTE=DrDevil;46765297]If you guys had to store data of a simulation with several million to billion data points (3d vectors), what format would you use?[/QUOTE]

Just a flat array with documented endianness. If you expect repetitions stream it through a compression algorithm.
At least that's the most convenient way to get reasonable storage. If the data is compressible you can likely find a better way to do it (but it would be a lot more complicated to set up).

If the data is composed of multiple frames of varying size I'd prefix it with an index so whoever reads it can skip around.
(You could also append it, but I'd only do that if you have absolutely no way of knowing how much space you'll need before processing the points.)

If it's just one huge point cloud but the user may want to examine certain parts I'd sort them into an adaptive tree structure and put that index at the front of the file, after a pointer to the data.
If you do it like this, a "dumb" program can still trivially open it and save it as single tree node if you don't want to bother sorting them.
(There are likely one or two possible tweaks that would make the format better than just the very plain specification, for example if you require a specific maximum amount per tree node the index alone would give you some rough density data. Choosing the right number most likely depends on the tree though.
You'd also need to decide whether to work with an initial bounding box or expand the tree upwards as you find points outside its reach. The former may require scanning through all points once before you can start sorting them.)

[QUOTE=DrDevil;46765297]If you guys had to store data of a simulation with several million to billion data points (3d vectors), what format would you use?[/QUOTE]

It depends a lot on the use case, the data itself sometimes it's not the most important thing, it could be more important what you do with it, are you going to search the existence of specific points? are you going to load a range of points? are you going to load all points? are going to do analysis over the points? is ACID important? is there more to it or is it a simple list of vectors? it's more important writing or reading speed?
