Hello,

I think about createing a directx binding for java. Do you think it is possible to use jna for this job or better use jni??

e.g

is it possible to map this code to java using jna: [code] typedef struct _D3DMATRIX { union { struct { float _11, _12, _13, _14; float _21, _22, _23, _24; float _31, _32, _33, _34; float _41, _42, _43, _44;

}; float m[4][4]; }; } D3DMATRIX; [/code]

or this one: [code] typedef interface IDirect3D9 IDirect3D9; [/code]

or this one: [code] #define INTERFACE IDirect3D9

DECLARE_INTERFACE_(IDirect3D9, IUnknown) { /*** IUnknown methods ***/ STDMETHOD(QueryInterface)(THIS_ REFIID riid, void** ppvObj) PURE; STDMETHOD_(ULONG,AddRef)(THIS) PURE; STDMETHOD_(ULONG,Release)(THIS) PURE;

/*** IDirect3D9 methods ***/ STDMETHOD(RegisterSoftwareDevice)(THIS_ void* pInitializeFunction) PURE; STDMETHOD_(UINT, GetAdapterCount)(THIS) PURE; STDMETHOD(GetAdapterIdentifier)(THIS_ UINT Adapter,DWORD

#ifdef D3D_DEBUG_INFO LPCWSTR Version; #endif }; [/code]

any suggestions are welcome.
