- /* Below are several defines needed by the generic parts of POV. You
- * may redefine them as needed in this config.h file.
- *
- * The following constants are needed by various POV modules. Each has
- * a default (shown below) which is will be defined in frame.h if you don't
- * define them here.
- *
- * #define EPSILON 1.0e-10 - a small value used for POLY
- * #define FILE_NAME_LENGTH 150 - default file name length
- * #define HUGE_VAL 1.0e+17 - a really big number
- * #define DBL_FORMAT_STRING "%lf" - the string to use for scanfs of doubles
- * #define DEFAULT_OUTPUT_FORMAT 'd' - the default +f format
- * #define RED_RAW_FILE_EXTENSION ".red" - for +fr, this is the extension for the
- * red file
- * #define GREEN_RAW_FILE_EXTENSION ".grn" - ditto for the green file
- * #define BLUE_RAW_FILE_EXTENSION ".blu" - ditto again for the blue file
- * #define FILENAME_SEPARATOR "/" - the character that separates names
- * in a path.
- * #define CASE_SENSITIVE_DEFAULT 2 - controls case sensitivity in DAT files
- * #define READ_FILE_STRING "rb" - special binary (raw, uncooked)
- * #define WRITE_FILE_STRING "wb" modes of fopen()
- * #define APPEND_FILE_STRING "ab"
- * #define NORMAL '0' - machine-specific PaletteOption settings
- * #define GREY 'G'
- *
- * These routines are required by POV to compute trace times. The defaults
- * shown below are defined in most versions of C. You may redefine them if
- * your compiler doesn't support these. If time is completely unsupported
- * define them as 0.
- *
- * #define START_TIME time(&tstart);
- * #define STOP_TIME time(&tstop);
- * #define TIME_ELAPSED difftime (tstop, tstart);
- *
- * Note difftime can be replaced with: #define TIME_ELAPSED (tstop - tstart);
- * in some cases.
- *
- * These are optional routines that POV calls. You may define them
- * or if undefined they will be defined as empty in frame.h.
- *
- * #define STARTUP_POVRAY - first executable statement of main
- * (useful for initialization)
- * #define PRINT_OTHER_CREDITS - used for people who extend the machine specific modules
- * (put your own printf's here)
- * #define TEST_ABORT - code to test for ^C or abort
- * (called on each pixel)
- * #define FINISH_POVRAY - last statement before exiting normally
- * #define COOPERATE - called for multi-tasking
- *
- * These items are standard on some C compilers. If they are not defined
- * on your compiler or are called something different you may define your
- * own or use the defaults supplied in frame.h as shown below.
- *
- * #define DBL double - floating point precision
- * #define ACOS acos - arc cosine of DBL
- * #define SQRT sqrt - square root of DBL
- * #define POW pow - x to the y power - x, y DBL
- * #define COS cos - cosine of DBL
- * #define SIN sin - sine of DBL
- * #define labs(x) (long) ((x<0)?-x:x) - Returns the absolute value of long integer x
- * #define max (x,y) ((x<y)?y:x) - greater of x and y
- *
- * On some systems "sprintf" returns the string rather than the length
- * of the string. If the string is returned, define the following:
- * #define STRLN(x) strlen(x)
- *
- * #define setvbuf(w,x,y,z) - some systems don't understand setvbuf.
- * If not, just define it away - it's
- * not critical to the raytracer. It
- * just buffers disk accesses.
- * This macro controls prototyping and is required by POV. Choose one
- * of the two options below or if left undefined it will default to ANSI
- * in frame.h
- *
- * #define PARAMS (x) x - do ANSI prototyping
- * #define PARAMS (x) () - do K&R non-ANSI prototyping
- *
- * These allow command line vs non-command line versions and alternate
- * main routines. Normally they should be undefined. Define them 1 if needed.
- * #define ALTMAIN 1
- * #define NOCMDLINE 1
