Hi,
I'm wanting to generate a full chain of mip-maps right down to 1x1 so that I can get the average luminosity of my rendered scene.
How would I go about doing this in DirectX 11?
I have setup the D3D11_TEXTURE2D_DESC with the right misc flags and was wondering what mipmap levels i should use.
Does setting the mip levels to 0 create a full chain or do you have to manually set the number?
My last question is my scene is rendered in widescreen 16:9 so the texture isnt square will I be able to go as low as 1x1?
Thanks in advance
