Hi all, as it's a larger chunk of functions, I felt like proposing my design idea for the D3DXCreateTexture/Volume/CubeTextureFromFile/Resource/FileInMemory/etc... functions. I'm CC'ing it to any wine d3dx coder I have in my addressbook yet, so sorry if I forgot one :)
So, the first thing I want to make sure is that we redirect the function calls correctly in order to reduce double coding. This means on the one hand that we should call the Extended versions of each function from inside of the simpler ones (most default parameters for the Ex functions are on MSDN) and on the other hand that we unify all D3DXCreateTextureFromXXEx functions somehow. I don't know how Resources are stored internally, but I guess the simplest would be to redirect all of them to D3DXCreateTextureFromFileInMemory, i.e. when D3DXCreateTextureFromFile is called we read the file into memory and call the InMemory function. I hope this shouldn't be too hard to be applied to the resource function either. Of course, this should also be done at the corresponding Surface, Volume and cube texture functions. Also, I haven't looked too much into it yet, but I guess we could go even a step further and define the CreateTextuteFromXX calls like this: 1. Redirect to the corresponding D3DXCreateXFromFileInMemoryEx call 2. Call D3DXCheckXRequirements 3. Call IDirect3DDevice9::CreateTexture 4. Lock its surface 5. Call LoadSurfaceFromFileEx with it
This would reduce most of our coding work on LoadSurfaceFromFileEx. However, there are still plenty of formats supported by the texturing functions and thus, plenty of work for us to do. IIRC we once came to the decision to use libraries like libpng or so to reduce that work, too, so we'd just need to implement formats like .dds.
And the last thing I'd like to ask goes to Louis Lenders: I've just found out that you have been working on a D3DXCreateTextureFromFile implementation. Are you still working on that? I'm really looking forward to do some coding work again, so I could continue your implementation from the 24th March if you've stopped to work on it ;-)
However, feel free to comment on my proposals for the texturing functions and tell me if you see any concerns with it :)
Best regards, Tony
