Join Engin Arslan for an in-depth discussion in this video Math.sin() and Math.cos(), part of Learning 3D Graphics on the Web with Three.js.
- [Instructor] Sine and cosine functions generates a value…in between minus one and one for a given value.…The values that are generated would be continuous…if the provided value is continuous as well.…One way of getting a continuous value in Three.js…will be to use the Three.js clock object.…Clock object tracks the time in the Three.js application.…We can call the getElapsedTime method on this object…to be able to get the elapsed time…since the start of the application…to feed it into a sine or a cosine function.…
I will be using the sine function in this example.…I will first start off by creating a clock object.…So here let's create a clock object…by calling the THREE.Clock function.…And let's pass this object inside our update function.…Here inside the update function,…remember we need to update this function in two places,…in this top level and inside…the requestAnimationFrame loop as well.…
So I will pass the clock object here too.…And now, inside this update function,…I can call the getElapsedTime method of the clock object…
