I want to create texture and fill it when created with some values, the texture has this:



texD.Width = res;
texD.Height = res;
texD.MipLevels = 1;
texD.ArraySize = 1;
texD.Format = DXGI_FORMAT_R16_FLOAT;  //yeah this format
texD.SampleDesc.Count = 1;
texD.SampleDesc.Quality = 0;
texD.Usage = D3D10_USAGE_DEFAULT;
texD.CPUAccessFlags = 0;
texD.MiscFlags = 0;
So when i create it i do this:
hr = g_pd3dDevice->CreateTexture2D(&texD, &rDSt, &TexJNMEMORY);
And fPixJN is this:
vector<float16> fPixJN(res*res);
float16 doesnt exist in c++ visual studio 2012, how can i create that vector so i can fill it with floats

If you're using DirectXMath it provides a HALF type (which is just a typedef for uint16_t, so you can use that as well). It also has conversion functions that can convert from 32-bit floats to 16-bit floats.

If you're using the older D3DX stuff, then you can use D3DXFLOAT16 which has constructors and casting operators that can convert to and from 16-bit floats. There's also D3DXFloat32To16Array for converting an entire array in one call.
