The SDK documentation has a section explaining the organization of texture resources in memory. Texture3D has a constructor taking a DataBox because DataBox contains volume data, which can be used to construct a volume texture.

Thanks for the clarification, i'll use a DataStream for now. Nov 13, 2009 issue 576 (Double memory usage on AudioBuffer/SourceVoice) Owner changed by Mike.Popoloski - The problem is that the audio data needs to stick around until XAudio2 is done consuming the whole buffer. We might be able to add a method that blocks until all the data has been processed by listening to XAudio2 events. For now, the preferred method of submitting audio data if you have an array is to wrap it in a DataStream, since SlimDX will check for this kind of stream and simply pass the pinned pointer along instead of reading the whole stream again.

There is no way to avoid copying and reusing the same memory/stream passed? It should be A LOT more efficient. (i'm optimizing my engine, and I see that most of the memory are used by the musics (4MB2 = 8 MB over a 30 MB total game (aka 26% of the memory usage...)) P.S.

In the game I was executing the update of the texture from the UPDATE TASK while the only thread that should do DirectX calls is the DRAW TASK.
