4 Creating and Editing NURB Patches

4 Q3NURBPatch_GetData

You can use the Q3NURBPatch_GetData function to get the data that defines a NURB patch and its attributes.

TQ3Status Q3NURBPatch_GetData (
TQ3GeometryObject nurbPatch, 
TQ3NURBPatchData *nurbPatchData);
nurbPatch A NURB patch.
nurbPatchData
On exit, a pointer to a TQ3NURBPatchData structure that contains information about the NURB patch specified by the nurbPatch parameter.

DESCRIPTION


The Q3NURBPatch_GetData function returns, through the nurbPatchData parameter, information about the NURB patch specified by the nurbPatch parameter. QuickDraw3D allocates memory for the TQ3NURBPatchData structure internally; you must call Q3NURBPatch_EmptyData to dispose of that memory.
