Anti-alias for lines

Mark,

I'm doing some line vector stuff and would like to know if you have any plans for Anti-alias to be turned on?

After some investigation:
* By default it's enabled on HTML5 (cannot be changed??)
* Xna: adding 'deviceManager.PreferMultiSampling = true;' to the gxtkGame constructor.

Re-prompting this one. Anyone know how this might work for GLFW?

Thanks

Ok - made extension for this one (XNA at this stage):

1. Create a folder called extension

2. Inside extension folder, create a file called extension.monkey and add this code:

Import "native/extension.${TARGET}.${LANG}"

Extern

#If TARGET="xna" Then
    Function SetAntiAlias:Void(value:Bool)="extension.SetAntiAlias"
    Function IsAntiAlias:Bool()="extension.IsAntiAlias"
    
#EndIf

Public

3. Create a folder called native (inside extension folder)

4. Inside native folder, create a file called extension.xna.cs and add this code:

class extension
{
    private static Boolean _antiAliasEnabled = false;
    
    public static void SetAntiAlias(Boolean value)
    {
        gxtkApp.game.deviceManager.PreferMultiSampling = value;
        gxtkApp.game.GraphicsDevice.PresentationParameters.MultiSampleCount = (value == true ? 4 : 0);
        gxtkApp.game.deviceManager.ApplyChanges();
        _antiAliasEnabled = value;
    }

    public static Boolean IsAntiAlias()
    {
        return _antiAliasEnabled;
    }
    
}

Some conjecture about what code properly turns on AntiAlias in XNA 4.0 but does a decent job at the moment.

I'd like anti aliased lines as well, for andriod/flash/xcode too.

Oh and Matt, thanks for sharing :)

Tibit,

No probs - I'm doing some vector stuff too so this is needed :)
