Callback function for Precomputed Radiance Transfer (PRT) simulation and compression.

Syntax

typedef HRESULT (WINAPI *LPD3DXSHPRTSIMCB)(
    FLOAT fPercentDone,
    LPVOID lpUserContext
);

Parameters

fPercentDone - Floating point number between 0 and 1.0 that represents the percentage of calculations completed (between 0 and 100 percent).

lpUserContext - Pointer to a user-defined value which is passed to the callback function; typically used by an application to pass a pointer to a data structure that provides context information for the callback function.

Return Value
