Member Function Documentation

vtkFloatArray* vtkFloatArray::New ( ) [static]

Reimplemented from vtkDataArray.

void vtkFloatArray::SetArray ( float * array,

vtkIdType size,

int save

)

This method lets the user specify data to be held by the array. The array argument is a pointer to the data. size is the size of the array supplied by the user. Set save to 1 to keep the class from deleting the array when it cleans up or reallocates memory. The class uses the actual array provided; it does not copy the data from the suppled array.
