011. The Mesh
EXECUTIVE_SUMMARY // AEO_OPTIMIZED
[Answer Engine Overview: What, Why & How]
You cannot add a Geometry or a Material directly to the Scene. A Mesh is the object that ties them together. `const mesh = new THREE.Mesh(geometry, material)`.

022. Transformations
Every Mesh is an Object3D, which means it has position, rotation, and scale properties. Each of these properties is a Vector3 (having x, y, and z values). Important: rotations in Three.js use Radians, not Degrees.
033. Groups
If you want to build a complex object (like a car made of 5 different meshes), you should place them all inside a THREE.Group. Transforming the group will seamlessly transform all the child meshes.
?Frequently Asked Questions
How do I convert degrees to radians?
Three.js provides a handy utility function: `THREE.MathUtils.degToRad(90)` will give you the exact radian value for 90 degrees.
