Utility Functions
QuickDraw 3D provides several mathematical utility functions. You can use the following two macros to convert degrees to radians, and vice versa.
#define Q3Math_DegreesToRadians(x) ((x) * kQ3Pi / 180.0) #define Q3Math_RadiansToDegrees(x) ((x) * 180.0 / kQ3Pi)You can use the following two macros to get the minimum and maximum of two values.
#define Q3Math_Min(x,y) ((x) <= (y) ? (x) : (y)) #define Q3Math_Max(x,y) ((x) >= (y) ? (x) : (y))
