2020-04-11Inverse cart: speed-up computation by 33%Even Rouault
Saves 2 sincos() and 1 atan2() calls. With the following bench ``` #include "proj.h" #include <stdlib.h> #include <stdio.h> #include <string.h> int main(int argc, char* argv[]) { if( argc != 2 ) { fprintf(stderr, "Usage: bench_inv_cart fwd/inv\n"); exit(1); } PJ* p = proj_create(0, "+proj=cart"); const int dir = strcmp(argv[1], "inv") == 0 ? PJ_INV : PJ_FWD; PJ_COORD coord; if( dir == PJ_FWD ) { coord.xyz.x = 3.14159/2; coord.xyz.y = 3.14159/2; coord.xyz.z = 100; } else { coord.xyz.x = 3e6; coord.xyz.y = 3e6; coord.xyz.z = 3e6; } for(int i = 0; i < 10* 1024 * 1024; i++ ) { proj_trans(p, dir, coord); } proj_destroy(p); return 0; } ``` On Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz Time before: 2.37s Time after: 1.57s

2020-04-04hgridshift/vgridshift: defer grid opening when grid has already been openedEven Rouault
Relates to #2115 With the fix of https://github.com/OSGeo/PROJ/pull/2128, transforming between EPSG:4326+3855 and EPSG:4269+5703 leads to many operations with many grids, and opening a file handle for each operation saturates the limit of 1024 file handles opened simunalteously. This fix defers grid opening when a transformation has already been instanciated with the same grid.

Return the index of the operation that would be the most appropriate to transform the specified coordinates. This operation may use resources that are not locally available, depending on the search criteria used by proj_create_operations(). This could be done by using proj_create_operations() with a punctual bounding box, but this function is faster when one needs to evaluate on many points with the same (source_crs, target_crs) tuple.
