GTK2+ installation still needs to be added to this Windows installation process. 2009-06-18 21:47 flypig * src/spherical.c: Fixed spherical translation bug for variable-coloured functions (was already fixed for single coloured functions). 2009-06-15 17:53 flypig * NEWS, configure.ac: Fixed bug that caused spherical functions to be centred incorrectly 2009-06-15 08:07 flypig * src/spherical.c, src/vis.c: Fixed translation error for spherical functions 2009-06-14 22:58 flypig * AUTHORS, README: Updated README and AUTHORS files 2009-06-14 21:51 flypig * configure.ac: Updated version number in configure.ac 2009-06-14 21:40 flypig * NEWS, README, examples/BouncingBall.xml: Version 0.2. 2009-06-14 20:48 flypig * examples/BouncingBall.xml: Added bouncing ball example. 2009-06-14 20:14 flypig * examples/Spiral01.xml, examples/Spiral02.xml, src/functy.c: Main window title now changes to fit the filename of the last loaded or saved file. 2009-06-14 18:47 flypig * src/cartesian.c, src/cartesian.h, src/function.c, src/functy.c, src/spherical.c, src/spherical.h, src/vis.c: Minor tweaks to set the default view and default functions. Translation of spherical functions no longer causes the vertices to be regenerated, providing a speed improvement. 2009-06-14 15:00 flypig * src/vis.c: Added clippling planes to x and y axes when rendering functions with spherical coordinates. This brings their behaviour closer to that of the Cartesian functions. 2009-06-14 02:33 flypig * src/filesave.c, src/function.c, src/function.h, src/functy.c, src/spherical.c, src/spherical.h, src/vis.c, ui/Functy.glade: Added user definable centre point for spherical coordinate graphs, including updated UI to accommodate it. 2009-06-08 22:10 flypig * ui/Functy.glade: Changed function edit window to include tabs. 2009-06-08 01:01 flypig * windows/build.bat: Updated Windows build file to incorporate new files for spherical/cartesian function rendering. 2009-06-08 00:59 flypig * examples/Spiral01.xml, examples/Spiral02.xml, src/Makefile.am, src/cartesian.c, src/cartesian.h, src/filesave.c, src/function.c, src/function.h, src/function_private.h, src/functy.c, src/functy.h, src/spherical.c, src/spherical.h, src/vis.c, src/vis.h, ui/Functy.glade: Added spherical co-ordinate function rendering. 2009-05-25 13:04 flypig * Makefile.am, NEWS, README, examples, examples/BumpySlides.xml, examples/Grid.xml, examples/Islands01.xml, examples/LavaLamp01.xml, examples/LavaLamp02.xml, examples/LissajousLights.xml, examples/Logo.xml, examples/Metal.xml, examples/Pulsate.xml, examples/ScaryForest.xml, examples/ScarySlides.xml, examples/Spikes01.xml, examples/Tartan.xml, src/functy.c, ui/Functy.glade: Improved user interface thanks to Vadi. Added example function files to the distribution build. 2009-04-23 20:15 flypig * ui/Functy.glade: Updated Functy UI to add scrollbars to the function list in the Functions window. 2009-04-22 23:08 flypig * src/functy.c: Fixed Functy to properly populate function list when loading new functions from file. 2009-04-22 19:33 flypig * src/functy.c, src/vis.c: Re-wrote Functy GTK functions to remove any remaining code from the original GtkGLExt logo demo. 2009-04-21 00:18 flypig * linux/build, src/Makefile.am, src/filesave.c, src/functy.c, src/functy.h, src/vis.c, windows/build.bat: Fixed Functy build files and compiler warnings. 2009-04-21 00:07 flypig * src/filesave.c, src/filesave.h, src/functy.c, src/functy.h, src/vis.c, src/vis.h, ui/Functy.glade: Added Functy file loading and saving dialogues.

Improved the function editing user interface. 2009-03-28 21:19 flypig * src/vis.c: Reverted previous accidental commit of wireframe Functy graph. 2009-03-28 21:17 flypig * src/vis.c: Moved the vertex index array from the Vis structure to the Function structure in Functy. This will allow different graphs to be drawn with different accuracies. 2009-03-28 21:15 flypig * src/function.c, src/function.h, src/vis.c: Moved the vertex index array from the Vis structure to the Function structure in Functy.
