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:
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; }Compile and run the project (F5), and you will now have antialiased edges.
How it works…
The following screenshot compares the difference between having antialiasing off and on—notice the jaggies along the bottom of the triangle...
