From c70554786db3e32ce5601b11d29d25db08cb2b37 Mon Sep 17 00:00:00 2001 From: Hans-Christoph Steiner Date: Thu, 13 Dec 2007 05:28:54 +0000 Subject: - reorganized files to build easy with Pd-extended. - updated NT macro to _MSC_VER since those pragmas are for MSVC only - put each object's "fill" function into that object's .c file, - added i0.c to the end of kaiser~.c since that's the only one that needs it - added #define powf pow for _WIN32 and Mac OS X for gaussian~.c since those platforms don't have single precision pow() by default svn path=/trunk/externals/windowing/; revision=9092 --- gaussian~.c | 24 ++++++++++++++++++++++-- 1 file changed, 22 insertions(+), 2 deletions(-) (limited to 'gaussian~.c') diff --git a/gaussian~.c b/gaussian~.c index 4716c8e..5ec3c47 100644 --- a/gaussian~.c +++ b/gaussian~.c @@ -20,15 +20,35 @@ */ #include "m_pd.h" -#include "windowFunctions.h" #include -#ifdef NT +#include + +#ifdef _MSC_VER #pragma warning( disable : 4244 ) #pragma warning( disable : 4305 ) #endif + #define DEFDELTA 0.5 #define DEFBLOCKSIZE 64 +/* MSW and OSX don't appear to have single-precision ANSI math */ +#if defined(_WIN32) || defined(__APPLE__) +#define powf pow +#endif + +void fillGaussian(float *vec, int n, float delta) { + int i; + float xShift = (float)n / 2; + float x; + if (delta == 0) { + delta = 1; + } + for (i = 0; i < n; i++) { + x = (i - xShift) / xShift; + vec[i] = (float)(pow(2, (-1 * (x / delta) * (x / delta)))); + } +} + static t_class *gaussian_class; typedef struct _gaussian { -- cgit v1.2.1
