Hi! I have imported a .x model into my C# application and I would like to anti-alias the model... I've been looking around for a while on how to do so, but I was unable to find answer... Any help would be appreciated :) Thank you

Are you familiar with the term multisample? When you create your render target you can specifiy a multismaple type which will enable anti aliasing by default. If you later wish to render without multisample you could set the render state, D3DRS_MULTISAMPLEANTIALIAS, to false.

But make sure your card supports it. Use CheckDeviceMultiSampleType for this purpose.

Multisampling is applied to a rendertarget or backbuffer, not to a certain object. You'll need to make your backbuffer multisampled by setting the proper members in the PRESENTATION_PARAMETERS struct when creating the device.

Actually, its both :-).

Yes, multisampling must be specified as part of the back buffer (and depth buffer) when creating those surface if you want to use it. However, once a buffer has multiple samples, then you can either use multisampling or not depending on how you set RS Multisample Antialias.
