Functions

void Rast3d_nearest_neighbor (RASTER3D_Map *map, int x, int y, int z, void *value, int type)
 The default resampling function which uses nearest neighbor resampling. This method converts the window coordinates x, y, and z into region coordinates and returned the nearest neighbor. More...
 
void Rast3d_set_resampling_fun (RASTER3D_Map *map, void(*resampleFun)(RASTER3D_Map *, int, int, int, void *, int))
 Sets the resampling function to be used by Rast3d_get_value () (cf.{g3d:G3d.getValue}). This function is defined as follows: More...
 
void Rast3d_get_resampling_fun (RASTER3D_Map *map, void(**resampleFun)(RASTER3D_Map *, int, int, int, void *, int))
 Returns in resampleFun a pointer to the resampling function used by map. More...
 
void Rast3d_get_nearest_neighbor_fun_ptr (void(**nnFunPtr)(RASTER3D_Map *, int, int, int, void *, int))
 Returns in nnFunPtr a pointer to Rast3d_nearest_neighbor () (cf.{g3d:G3d.nearestNeighbor}). More...
