Hello, How can I fill a A16R16G16B16F texture when locking it ? There is no 16 bits float type in C++. Is there a special class for this ? Must I operate a copy from a 32 bits texture ?

You want to look into OpenEXR.

D3DXFLOAT16 is a 16 bit float.

You should check out D3DXFloat32To16Array which converts an array of 32 bit floats to 16 bit, and the converse D3DXFloat16To32Array which goes the other way,

Hope that helps,
Tim
