From 7719d297f2a1da0e45fd39cad21e99e23fd695c8 Mon Sep 17 00:00:00 2001 From: Tomer Shalev Date: Fri, 15 Jan 2010 05:53:15 +0000 Subject: FS#10911 - Plugins: Fractals (formerly Mandelbrot) - Rename the mandelbrot plugin to fractals - Update manual accordingly - Separate plugin's functionality into separate files - Lay the ground for having fractals sets other than the Mandelbrot set. For that the following will need to be implemented: - Create a new file for the new fracral set - Provide key mapping to switch between sets git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24230 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugins/CATEGORIES | 2 +- apps/plugins/SOURCES | 1 - apps/plugins/SUBDIRS | 1 + apps/plugins/fractals/SOURCES | 10 + apps/plugins/fractals/cpu_arm.c | 40 ++++ apps/plugins/fractals/cpu_arm.h | 27 +++ apps/plugins/fractals/cpu_coldfire.c | 58 +++++ apps/plugins/fractals/cpu_coldfire.h | 29 +++ apps/plugins/fractals/cpu_sh7043.c | 94 ++++++++ apps/plugins/fractals/cpu_sh7043.h | 29 +++ apps/plugins/fractals/fractal.c | 260 ++++++++++++++++++++++ apps/plugins/fractals/fractal.h | 352 +++++++++++++++++++++++++++++ apps/plugins/fractals/fractal_rect.c | 209 ++++++++++++++++++ apps/plugins/fractals/fractal_rect.h | 38 ++++ apps/plugins/fractals/fractal_sets.h | 52 +++++ apps/plugins/fractals/fractals.make | 21 ++ apps/plugins/fractals/mandelbrot_set.c | 392 +++++++++++++++++++++++++++++++++ apps/plugins/fractals/mandelbrot_set.h | 60 +++++ manual/plugins/fractals.tex | 81 +++++++ manual/plugins/main.tex | 4 +- manual/plugins/mandelbrot.tex | 81 ------- 21 files changed, 1756 insertions(+), 85 deletions(-) create mode 100644 apps/plugins/fractals/SOURCES create mode 100644 apps/plugins/fractals/cpu_arm.c create mode 100644 apps/plugins/fractals/cpu_arm.h create mode 100644 apps/plugins/fractals/cpu_coldfire.c create mode 100644 apps/plugins/fractals/cpu_coldfire.h create mode 100644 apps/plugins/fractals/cpu_sh7043.c create mode 100644 apps/plugins/fractals/cpu_sh7043.h create mode 100644 apps/plugins/fractals/fractal.c create mode 100644 apps/plugins/fractals/fractal.h create mode 100644 apps/plugins/fractals/fractal_rect.c create mode 100644 apps/plugins/fractals/fractal_rect.h create mode 100644 apps/plugins/fractals/fractal_sets.h create mode 100644 apps/plugins/fractals/fractals.make create mode 100644 apps/plugins/fractals/mandelbrot_set.c create mode 100644 apps/plugins/fractals/mandelbrot_set.h create mode 100644 manual/plugins/fractals.tex delete mode 100644 manual/plugins/mandelbrot.tex diff --git a/apps/plugins/CATEGORIES b/apps/plugins/CATEGORIES index fc9589282e..a41514f93d 100644 --- a/apps/plugins/CATEGORIES +++ b/apps/plugins/CATEGORIES @@ -41,7 +41,7 @@ keybox,apps lamp,apps logo,demos lua,viewers -mandelbrot,demos +fractals,demos matrix,demos maze,games mazezam,games diff --git a/apps/plugins/SOURCES b/apps/plugins/SOURCES index a3ce60fbf8..16f7ff6f9a 100644 --- a/apps/plugins/SOURCES +++ b/apps/plugins/SOURCES @@ -77,7 +77,6 @@ codebuster.c /* Plugins needing the grayscale lib on low-depth LCDs */ fire.c -mandelbrot.c plasma.c blackjack.c diff --git a/apps/plugins/SUBDIRS b/apps/plugins/SUBDIRS index 587050fb94..0993e8221c 100644 --- a/apps/plugins/SUBDIRS +++ b/apps/plugins/SUBDIRS @@ -20,6 +20,7 @@ rockboy pictureflow #endif chessbox +fractals jpeg sudoku reversi diff --git a/apps/plugins/fractals/SOURCES b/apps/plugins/fractals/SOURCES new file mode 100644 index 0000000000..72a22467c2 --- /dev/null +++ b/apps/plugins/fractals/SOURCES @@ -0,0 +1,10 @@ +fractal.c +fractal_rect.c +mandelbrot_set.c +#if CONFIG_CPU == SH7034 +cpu_sh7043.c +#elif defined CPU_COLDFIRE +cpu_coldfire.c +#elif defined CPU_ARM +cpu_arm.c +#endif diff --git a/apps/plugins/fractals/cpu_arm.c b/apps/plugins/fractals/cpu_arm.c new file mode 100644 index 0000000000..1d8b1a76f6 --- /dev/null +++ b/apps/plugins/fractals/cpu_arm.c @@ -0,0 +1,40 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2009 Tomer Shalev + * + * + * This program is free software;
