Method Detail

clamp

public static double clamp(double value,
                           double min,
                           double max)

Test a value in specified range, returning minimum if it's below, and maximum if it's above

Parameters:

value - Value to test

min - Minimum value of range

max - Maximum value of range

Returns:

value if it's between min and max, min if it's below, max if it's above

clamp

public static float clamp(float value,
                          float min,
                          float max)

Test a value in specified range, returning minimum if it's below, and maximum if it's above

Parameters:

value - Value to test

min - Minimum value of range

max - Maximum value of range

Returns:

value if it's between min and max, min if it's below, max if it's above

wrap

public static double wrap(double value,
                          double min,
                          double max)

Constrains value to the given range (including min, excluding max) via modular arithmetic.

Same formula as used in Core GL (wrap.hpp) std::fmod((std::fmod((value - min), d) + d), d) + min;

Parameters:

value - Value to wrap

min - Minimum value

max - Maximum value

Returns:

Wrapped value
