template<typename T >
void GT_OSDBfrSurface::evaluate ( T *  result,
T *  du,
T *  dv,
int  subface,
float  u,
float  v,
const GT_DataArrayHandle &  patchpoints 
) const
inline

Evaluate attribute and its derivs at specified coordinate. subface index can be obtained by counting digits to subtract from ptexid until it maps to a different face (using ptex->face mapping from GT_OSDTopology). T must be a float type (accepts 64-bit but beware that it'll be interpolated in 32-bit). The tuple count in result array must match the tuple count in patchpoints. du and dv may be nullptr if not needed.

GT_DataArrayHandle GT_OSDBfrSurface::preparePatchPoints ( const GT_DataArrayHandle &  attrdata) const
inline

Calculate patch points to pass to evaluate functions. Input attrdata must be of float type. Returns GT_DANumeric of same type. Using fpreal32 storage is highly recommended for performance reasons. It's up to the caller to store and manage the returned data for reuse. May return nullptr if unknown data type.
