What Are You Working On? - August 2014

[cartman300]

I finally got my thing to render on nVidia cards, and i finally figured out what was the problem after very very much testing, basically i just mistyped a variable type in fragment shader for the screen quad from vec4 to vec3 and it renders just fine on ATI cards because it seems it defaults to 1 there while it defaults to 0 on nVidia cards making it transparent.

C++, GLEW, GLFW, and QT

Edit:
Any suggestions how to handle objects that belong in 2 or more nodes of an octree ? store them in each of them ? or only in the parent node ? or something else ? divide it (not a good option i guess...)?

I'm working on a game engine, here's a random character generator:

Trying to convert game's alien color format

        public static Color GetColorFrom16bit(UInt16 n)
        {
            //4:4:3:5
            byte R = (byte)((n >> 12) << 4);
            byte G = (byte)(((n << 4) >> 8) << 4);
            byte B = (byte)(((n << 8) >> 5) << 5);
            byte A = (byte)((n << 11) >> 8);

            Color color = Color.FromArgb(A, R, G, B);

            return color;
        }

        public static UInt16 Get16bitFromColor(Color c)
        {
            return (UInt16)(((c.R >> 4) << 12) | ((c.G >> 4) << 8) | ((c.B >> 5) << 5) | (c.A >> 3));
        }

For some reason Get16bitFromColor produces slightly off Reds. I have no idea :suicide:
I've only recently started using bitwise operations. So that might be it.

Reading straight from the game's files:

Exporting and then importing the same sprite:

It's slightly darker which completely fucks up the rendering in-game. :suicide:

C++ with SFML for window creation/input handling and GLM for some data structures.

require Dash

class Fibonacci
{
  defn Integer run(Integer n)
    where(n < 2)
  {
    return n
  }

  defn Integer run(Integer n)
  {
    return run(n - 1) + run(n - 2)
  }
}

This is what dash looks like so far

What are those components? It reminds me of unpacking bits in MIPs :v: Shifting x bits right then y left to remove x bits and pad with y zeroes.

It's two color channels and one alpha channel.

5:6:5

I can so far convert these channels into a presentable pixel but if i do the inverse the colors get messed up. That line is trying to do the inverse.

Wasn't the conversion for that some non power of two factor? If you just bit shift it's going to turn out too dark in the higher range.

DON'T shift right then left or vice-versa :v: use masks.

Your problem, by the way (I think) is that the left-shift by 11 is happening [I]before[/I] the cast to uint16, so you're shifting an 8-bit number and chucking out all of the data.

Personally I'd end up writing it like this

return ((((UInt16)c.R) & 0xf8) << 8) |
       ((((UInt16)c.G) & 0xfc) << 3) | 
       (((UInt16)c.A)  >> 3);

[Z_guy]

So I opened up UnityEngine.dll in ILSpy, and in the Mathf class found this:
[csharp]
public static float Sin(float f)
{
return (float)Math.Sin((double)f);
}
public static float Cos(float f)
{
return (float)Math.Cos((double)f);
}
public static float Tan(float f)
{
return (float)Math.Tan((double)f);
}
[/csharp]

It's just calling the System.Math methods.
I kinda expected there to be internal calls to the native C++ sin family, but that's probably not faster anyway.

Also, for some reason Mathf is a struct instead of a static class.

Rewriting and refactoring is such a pain. It's fine when it's just a single function, but I have to rewrite about 50% of my engine so far to accommodate for me switching data structures.

[HiredK]

I recently started a blog where I showcase all my older projects. The quality of the code is pretty bad for some of them since they date from a few years back but maybe some of you might be interested anyway.
