Getting the depth buffer's content

Hi,

I have a GeForce 7800 GTX 512 based card and was surprized to find out

that the driver for it states ( in the caps ) that there is no support for D3DFMT_D16_LOCKABLE .

I want to get the content of the depth buffer - How can I do that

Thanks' In Advance : Lior Canetti .

Hi,

Thank's for the replay, but it does't help Me, because as You can

understand from My first post, I have used that method and got the surface,

but the LockRect() function failed because the surface was not in the D3DFMT_D16_LOCKABLE format, which by the Direct3D's documentation

is the only depth / stencil lockable format, allthow

D3DFMT_D32F_LOCKABLE ( which is allso not supported by any card I know of ) is allso in the enumeration .

I will be happy to receive any help .

Thank's In Advance : Lior Canetti .

You could easily retrieve the depth/stencil surface using the IDirect3DDevice9::GetDepthStencilSurface(&userDefinedSurface) or the Device.DepthStencilSurface. Then you can perform the necessary functions that you need to get the contents.

You could lock the surface and read the contents etc...

I hope this helps.
Take care.

Unfortunately you can’t do this with nVidia hardware. What do you want to do with the depth values Maybe there is another way to reach your aim.
