From 375d87a9b0ec1cf2fffd705adb870c86144d2400 Mon Sep 17 00:00:00 2001 From: Johannes Hofmann Date: Mon, 26 Oct 2026 20:05:20 +0100 Subject: Replace the C++ implementation with the Rust port The Rust port (formerly gipfel-rs) is now the official successor to the FLTK/GSL C++ code base. This squashes the port into a single commit and removes the C++ sources (they remain in the git history below). Layout: crates/gipfel-core headless core: hills, panorama geometry, projections (maxima-generated derivatives), pure-Rust LM fit, gipfel: JPEG comment + EXIF I/O, profiles, stitching crates/gipfel-cli command-line tools (export, info, stitch, profiles) crates/gipfel-app Cosmic DE (libcosmic) GUI, binary name `gipfel` codegen/ maxima scripts + regen.sh for the projection code tests/ golden files + C++ reference harnesses (historical) The original README is kept for now; it will be updated to describe the Rust build. gipfel.dat, AUTHORS, ChangeLog and NEWS are unchanged. --- tests/harness/funcsdump.cxx | 60 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 tests/harness/funcsdump.cxx (limited to 'tests/harness/funcsdump.cxx') diff --git a/tests/harness/funcsdump.cxx b/tests/harness/funcsdump.cxx new file mode 100644 index 0000000..b416f2c --- /dev/null +++ b/tests/harness/funcsdump.cxx @@ -0,0 +1,60 @@ +// Golden dump of the maxima-generated projection functions (C reference). +// The `#define` trick turns the generated class methods into free functions. +#include +#include + +static double sec(double a) { return 1.0 / cos(a); } + +// gen_golden.sh copies the generated files with the class scope replaced: +// ProjectionRectilinear::rect_mac_x -> rect_mac_x, ProjectionCylindrical::rect_mac_x -> cyl_mac_x +#include "rect_funcs.cxx" +#include "cyl_funcs.cxx" + +int main(void) { + for (int k = 0; k < 200; k++) { + double kk = (double) k; + double c_view = -3.0 + 0.03 * kk; + double c_nick = 0.10 * sin(0.11 * kk); + double c_tilt = 0.05 * cos(0.07 * kk); + double scale = 2000.0 + 37.0 * fmod(kk, 19.0); + double k0 = 0.001 * sin(0.31 * kk); + double k1 = 0.0001 * cos(0.17 * kk); + double x0 = 50.0 * sin(0.13 * kk); + double m_view = c_view + 0.5 * sin(0.23 * kk); + double m_nick = 0.05 * cos(0.19 * kk); + + printf("%.17g %.17g %.17g %.17g %.17g %.17g %.17g %.17g %.17g ", + rect_mac_x(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dc_view(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dc_nick(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dc_tilt(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dscale(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dk0(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dk1(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_x_dx0(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick)); + printf("%.17g %.17g %.17g %.17g %.17g %.17g %.17g ", + rect_mac_y_dc_view(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dc_nick(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dc_tilt(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dscale(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dk0(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dk1(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + rect_mac_y_dx0(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick)); + + printf("%.17g %.17g ", + cyl_mac_x(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_y(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick)); + printf("%.17g %.17g %.17g %.17g ", + cyl_mac_x_dc_view(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_x_dc_nick(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_x_dc_tilt(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_x_dscale(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick)); + printf("%.17g %.17g %.17g %.17g\n", + cyl_mac_y_dc_view(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_y_dc_nick(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_y_dc_tilt(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick), + cyl_mac_y_dscale(c_view, c_nick, c_tilt, scale, k0, k1, x0, m_view, m_nick)); + } + return 0; +} -- cgit v1.2.3
