![]() ![]() ![]() Three.js has a built-in loader to load these models into the scene. Fortunately, there are many 3D models available online, or perhaps you or a friend have played with making models in 3D animation applications like Blender. As you can imagine, building up a complex 3D world or character using this method would be very tedious. We've created some basic 3D shapes programmatically. You can also define different materials for the torus and cube, to make them look different. Try changing up the material color and see what happens. Press the "Run" button again and you should see the torus and cube rotating in the Replit window: To kick off the animation for the first time, we call the animate() function ourselves. ![]() We call this function so that we can keep the animation running. Each time animate() is called, requestAnimationFrame will call it again for the next frame. The requestAnimationFrame function is a built-in browser API call that will fire the animate() function on the next frame. This will cause the scene to be redrawn every frame, with the updated rotations. This is a handy method that saves us from calculating the rotation ourselves.Īfter we rotate the objects, we call the renderer.render(scene, camera) method to draw the scene. We rotate the torus and cube by 0.01 radians around the objects' x and y axes using the rotation property of each mesh. This creates a new function, animate(), that will be called on every frame.
