Fundamentals of 3D Rendering – Its Different Applications

Modern computer software enables artists and designers to use a new form of canvas: 3D rendering/modeling.

A 3D rendering is a 2D representation of objects based on a computer generated wireframe model. The color, lighting, textures, shadows, and the material are transposed onto the wireframe in order to create photorealistic images.

The most widely known use for 3D technology is in cinema. For instance, the animated Toy Story movies are a good example. While doing your research, I’m sure you have also come across 3D modeling. While they are usually interchanged, they can actually be clearer distinguished from each other. This interesting post that talks about the definition of 3D modeling and rendering will surely help clear up a lot of information.

The Basics of 3D Rendering

How are 3D Renderings Created?

In order to create a 3D render, two types of computer software are needed: modelers and renderers.

There is a three step process used to create a 3D render/image. The following is a basic breakdown of how a render is performed:

Step 1

The first step in the process is 3D modeling. This process creates a series of flat geometric shapes that are connected together to form polygons.

This process is similar to how a professional artist draws a subject. All subjects start out as a series of basic shapes like circles, squares, triangles, and rectangles.

Computer software is then used in order to manipulate the 3D model. The output is essentially a rough outline of what the final product will look like. The object will resemble a RAW wireframe of an object or scene.

Step 3

The wireframe is further refined through the use of various textures, colors, lighting, filters, and shading.

Applications of 3D Rendering

Real Estate

In real estate, making use of dynamic visuals is the key to success. While pictures and 360 degree tours are beneficial, a 3D rendering offers a more realistic image. A potential buyer can use the rendering to virtually walk through the space without having to see it in person.

A broker may have buyers that live in other parts of the world. For instance, a family that’s relocating may not be able to fly back and forth for an in-person walk-through. 3D tours are able to be posted on real estate websites in order to attract potential buyers or investors.

Interior Design

In the past, interior designers only made use of swatches and drawings. Today, designers use rendering software to show clients what a room, space, or structure will look like. A schematic can be rendered to help plan how the space will be used: site plan, floor plan, and elevations.


The same 3D rendered blueprints can be shared among the people doing the construction (crew and foreman). This way all parties know and understand the end goal. They may also be able to provide additional insight into potential problems.

An advantage of 3D rendering is that it helps speed up the design process and can help clients and investors visualize what the completed product, structure, or space will look like.

3D rendering also makes it easier to spot potential problems and changes can be made relatively easily.

A 3D animation allows for clients to do a virtual walkthrough before construction even starts.

It’s now possible for products to be realistically and dynamically depicted and rendered. 3D rendering may also be used in the creation of images of product packaging, prototypes, and more.

3D rendering of products can then be utilized for campaigns both in digital and print medium as a way to sell the product before it even exists. This can be useful when you’re trying to raise capital.

Video Games

3D rendering has allowed for video games to be more realistic than ever. Most games make use of this technology, from creating large civilizations to high octane first person shooters. You can render scenery, textures, lighting as well as objects like vehicles, people, animals, etc.
