MathUtils.degToRad()

The MathUtils.degToRad() function is a utility function provided by the Three.js library to convert values from degrees to radians.

Syntax

MathUtils.degToRad(degrees)

Parameters

• degrees - input angle in degrees

Return Value

The function returns the input angle converted to radians.

Examples

Example 1

Convert 45 degrees to radians.

const angleInDeg = 45;
const angleInRad = MathUtils.degToRad(angleInDeg);
console.log(angleInRad); // Output: 0.7853981633974483

Example 2

Find the sine of an angle in degrees.

const angleInDeg = 30;
const angleInRad = MathUtils.degToRad(angleInDeg);
const sinValue = Math.sin(angleInRad);
console.log(sinValue); // Output: 0.5

Remarks

The MathUtils.degToRad() function is mainly used in graphics programming for converting angles between different systems of measurement. Since the Three.js library mainly deals with 3D graphics and animations, this function becomes essential for developers.
