hi everybody,

I have a question about DirectX11, I need to create water and modelize the refraction of the water. So i have a map and i need the texture that represent my map. I think that i must use a render target but I don't know how do that. Can you give me an example of render target please?

Thank you for your help.

In DX9, you call IDirect3DDevice9.SetRenderTarget and pass in an IDirect3DSurface9. You can get a surface from an IDirect3DTexture9 with IDirect3DTexture.GetSurfaceLevel. You can also get a surface from a swap chain.
