// LinearInterpolation.h
// Declares methods for linear interpolation over 1D, 2D and 3D arrays

// 2D and 3D Interpolation is optimized by precalculating the ratios into static-sized arrays
// These arrays enforce a max size of the dest array, but the limits are settable here:

const int MAX_INTERPOL_SIZEY = 512; ///< Maximum Y-size of the interpolated array
const int MAX_INTERPOL_SIZEZ = 256; ///< Maximum Z-size of the interpolated array
/** Puts linearly interpolated values from one array into another array. 1D version */

float * a_Src, ///< Src array
int a_SrcSizeX, ///< Count of the src array
float * a_Dst, ///< Src array
int a_DstSizeX ///< Count of the dst array
);
/** Puts linearly interpolated values from one array into another array. 2D version */
