Lighting

In our real nature world, light is everywhere. There are many light sources, such as sunlight, lightning, the light bulb, etc. Different intensity of light from the light sources will provide you a different feeling about an object or a scene. It plays a key role in rendering. To create more perfect object as in real life, you will need to set light in your scene. While we use 3Ds max, we can choose many different light types from it. As I read the blog from (Masters, 2013) in the website (digitaltutors.com), I have learned the several types of light you can apply: spot lights, point light, area lights, directional light, volume light and ambient light. Spotlight is emitted from a direct source in a cone-shape field such as flashlight. Point light is like a light bulb emits light from the center and in round dimension. Area lights is the light within a limited area. Direction light is the daylight that gets from sun. Volume light is similar to point light but it can have specific shapes. And ambient light is the light that comes from every direction. Hence it will not have the shadow projection.

Rendering

3D rendering is generating 2D images or scenes that can be represented by the original 3D models. It gathers various components such as texturing, lighting, and shading to form a result. Rendering process is taking through computer application and come up as an output file. This process will be takes a really long time despite of any kind of quality computer you are using. To better solve this question, artist usually will render every short-interval work they have done. And then edit them together.

Compositing

3D compositing is a stage where you combine and composite various rendered elements or generated images and scene in layers to produce animation. It can deliver a fantastic lifelike visual effect. There are two composing types which are nodes- based compositing and layer-based compositing. Basically, they can do the same things but just in different ways. In node-based compositing, elements are linked together by form structure shown in a node graph, this node graph looks like a tree map. And in layer-based composing is assembling several render elements in separate layer within a timeline and every layer overlap each other.
