Method Detail

clamp

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

Clamp value to range [min, max]

Parameters:

val - Value to clamp.

min - Minimum value.

max - Maximum value.

Returns:

The value between [min, max] Example:

     double val = 195;
     //Clamp value to [0, 100]
     double clampedValue = MathUtils.clamp(val, 0, 100);
     //This will output 100
     System.out.printf("Value = %d", val);
 

toDegree

public static Vector3 toDegree(Vector3 radian)

Convert a Vector3 from radian to degree.
