// LinearInterpolation.h
// Declares methods for linear interpolation over 1D, 2D and 3D arrays
#pragma once
// 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_SIZEX = 256; ///< Maximum X-size of the interpolated array
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
void LinearInterpolate1DArray(
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
void LinearInterpolate2DArray(
float * a_Src, ///< Src array, [x + a_SrcSizeX * y]
int a_SrcSizeX, int a_SrcSizeY, ///< Count of the src array, in each direction
float * a_Dst, ///< Dst array, [x + a_DstSizeX * y]
int a_DstSizeX, int a_DstSizeY ///< Count of the dst array, in each direction
);
/// Puts linearly interpolated values from one array into another array. 3D version
void LinearInterpolate3DArray(
float * a_Src, ///< Src array, [x + a_SrcSizeX * y + a_SrcSizeX * a_SrcSizeY * z]
int a_SrcSizeX, int a_SrcSizeY, int a_SrcSizeZ, ///< Count of the src array, in each direction
float * a_Dst, ///< Dst array, [x + a_DstSizeX * y + a_DstSizeX * a_DstSizeY * z]
int a_DstSizeX, int a_DstSizeY, int a_DstSizeZ ///< Count of the dst array, in each direction
