Applying multisample anti-aliasing

In this recipe, we will enable multisample antialiasing (MSAA) to smoothen lines and edges.

Getting ready

We can apply this recipe to any of our recipes that are implemented with a class that
descends from D3DApplicationBase . Otherwise, this can be easily adapted to work
with the creation of any swap chain.

How to do it…

We can smooth the lines in our example by enabling multisampling:

1. To do this, simply override the D3DApplicationBase.

CreateSwapChainDescription() method in our class as follows:
protected override SwapChainDescription1
CreateSwapChainDescription()
{
var description = base.CreateSwapChainDescription();
description.SampleDescription. Count = 4;
description.SampleDescription. Quality = 0;
return description;
}

2. Compile and run the project ( F5 ), and you will now have antialiased edges.
