Hi guys,
I'm not sure about a few things relating to downsampling and upsampling. If it matters, I'm only downsampling to 1/2 the screen size.
Should I use point sampling and do all the work myself in a shader, or should I use linear sampling and enhance that with a shader ?
D3D11_FILTER_MIN_MAG_MIP_POINT or D3D11_FILTER_MIN_MAG_MIP_LINEAR ?
I'm pretty sure I use D3D11_TEXTURE_ADDRESS_CLAMP, is that right ?
Also, do I simply render a quad with coordinates (-1,-1...1,1) ? That seems fine but I want to make sure.
And finally, about upsampling, do I need to do anything special to bring it back to screen size ?
I know there are a few techniques like average, tent, etc., I will try them all but first I want to make sure I'm doing the basics correctly.
Thanks a lot.
