## Detailed Description

A GridTransformer applies a geometric transformation to an input grid using one of several sampling schemes, and stores the result in an output grid.

Note
  GridTransformer is optimized for affine transformations.

Usage:

Mat4R xform = ...;
GridTransformer transformer(xform);
transformer.transformGrid<BoxSampler>(inGrid, outGrid);

GridTransformer(const Mat4R &xform)

Definition Interpolation.h:120

or

Vec3R pivot = ..., scale = ..., rotate = ..., translate = ...;
GridTransformer transformer(pivot, scale, rotate, translate);
transformer.transformGrid<QuadraticSampler>(inGrid, outGrid);
