template<typename T >

void GT_OSDBfrSurfaces::evaluate ( T *  result, T *  du, T *  dv, int  ptexid, float  u, float  v, const GT_DataArrayHandle &  patchpoints  ) const

inline

Evaluate attribute and its derivs at specified coordinate. 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.

template<typename T >

void GT_OSDBfrSurfaces::evaluateFV ( T *  result, T *  du, T *  dv, int  ptexid, float  u, float  v, const GT_DataArrayHandle &  patchpoints  ) const

inline

Evaluate attribute and its derivs at specified coordinate. 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.

exint GT_OSDBfrSurfaces::getMemoryUsage

(

)

const

Minimum. The actual usage may be far greater.

const int* GT_OSDBfrSurfaces::getPtexMap ( ) const

inline

Get Ptex to base face mapping.

Definition at line 694 of file GT_OSD3.h.

GT_DataArrayHandle GT_OSDBfrSurfaces::preparePatchPoints ( const GT_DataArrayHandle &  attrdata ) const

inline

Calculate patch points for all surfaces to pass to evaluate functions. Input attrdata must be of float typpe. Returns GT_DANumeric of same type. It's up to the caller to store and manage the returned data for reuse. May return nullptr if invalid (eg surfaces don't exist or the input attrdata is unsupported type)
