Determines whether the specified Object is equal to the current Object.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Interpolate a value at the specified 2D position

Resample the interpolation grid, basically halfing the dx and dy in the grid by adding mid points between all current points.

If the original grid was a 3x3 grid, the new grid after resampling is 5x5, and then 9x9 and so on.

Returns a string that represents the current object.
