What is 3D Rendering? A Brief Explanation Everyone Should Know

According to Wikipedia, 3D Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life.

Several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more advanced techniques such as: scanline rendering, ray tracing, or radiosity. Rendering may take from fractions of a second to days for a single image/frame. In general, different methods are better suited for either photo-realistic rendering, or real-time rendering.

3D rendering is not just bound to the graphics design industry only. For its vast workable platforms, this technology has gone beyond one industry. It is just an awesome engineering marvel that is used in the medical industry, video industry, movie industry, architectural industry and so on. And this article aims to send you a message of why and how this 3D rendering tech is a must to be used for the future technological progress.

So What is 3D rendering?

3D rendering is a representation of two-dimensional computerized wireframe. And this wireframe is given just the perfect shadow, lighting, textures as well as regularly used tools and materials into the frame. The fun thing is, looking at a billboard or a magazine’s graphical image, we don’t know that these are made using 3D architectural rendering. Love to see Tony Stark wearing his giant metal robotic body fighting with the bad guys and flaming them with a hand-attached gun in Iron Man movie? We all love it but how many of us know that all the animations are made by 3D rendering? This technology is just everywhere, in the magazine, on the TV, on the cover of our books, in the advertisement and in many more digital media. This technology is moving so fast that even we can’t keep cope with it.

The Post-mortem of 3D rendering.

There are two types of software needed to complete a 3D rendering task and they are:

1. Modelers (eg.  Z brush, Modo, Houdini, Rhino 3D, Mudbox, Cinema 4D, Maya & Max etc)

2. Renderers (eg. Vray, Mental Ray, Corona, Art Renderer, Artlantis, Lumion 3D, Maxwell etc)

Rendering starts with just a rough 3D model. That model is consists of a series of geometric shapes in a which are connected together is a three dimensional way. These geometric shapes are called ‘Ploygons’. These geometric shapes or Ploygons are the backbone of any digital 3D modeling. The 3D model is created and manipulated using computer software like 3DStudio Max, SketchUp or Rhinoceros 3D. The models that come from this software are an unrefined version of the final model. The models are shown like a RAW wireframe scene or object. RAW models need to be refined by giving them shades, textures, artificial light source, and some other filters. The end product is purely refined and nicely shaped by 3D rendering.

There is also some additional software needed to after the modeling and rendering tasks. But these are not mandatory. It is called the post-production process. Software like Photoshop gives the final product a finishing touch which makes the design loke alive. In order do all these time-taking and complex software, a 3D rendering artist must need to have all these software expertise in his/her fingertip. Otherwise, the final product will not be in the highest quality.

The Birth of 3D Rendering.

Aircraft is awesome. It flies us thousands of feet above the clouds and crosses us the Atlantic ocean in a matter of some hours. But the journey of the airliner is not as easy as we think. It had difficulties. And those difficulties gave us a solution called 3D rendering. You may ask me that, what is the relationship between aircraft and 3D rendering. Yes, there is a relationship. And the relationship lies in the cockpit of an aircraft. Back in those days, no aircraft had anything called autopilot. In 1990, a computer graphics designer named William Fetter was given a task to utilize the empty space of an aircraft’s cockpit. There was a need for an autopilot system because of the pilots boring hours long journey. William Fetter was ended up with a computer generated orthographic sketch of the human form. He named it ‘Computer Graphic’ and after that everything is history.

William Fetter Walking in the footsteps of William Fetter, Dr. Ivan Sutherland experimented step one step further. He invented a sketchpad and the world first saw a complete 3D computer modeling program. This software enabled a person to work with or create an image on a computer screen. It was the first footstep of Graphical User Interface (GUI).

Dr. Ivan Sutherland After that, we all know what happened. All happened before our eyes. Computer got faster, software got smarter and the tools that need to manipulate all the complex works of 3D, become sophisticated.

3D Rendering Software/Tools

Maybe you are planning to be a rendering expert and can’t find the best software to do it! OK, take the first step first. Start learning what 3d rendering is and why you should learn it. If you are not a designer from the base, then learn the basics first. Otherwise, there is no way left to learn to render. 3D architectural rendering is the latest technological path to design an interior or exterior structure in a photographic like image. That’s why around the world 3d architectural rendering services are getting very much popular and a well-known profession.

OK, you are an expert? Then this article is the path for you. We’ve gathered 22 best and most advanced rendering software. These are the best option for animation movies, effects rather than just doing 3d rendering. 3d rendering is the final stage of 3d animation or 3d model. Because 3d rendering is a complex process and an integral part of the movie or architecture industry, there is so many software available today. So, it has become more difficult to find out the perfect and suitable software to do a particular work. To help you find the right 3d rendering software, we’ve gathered the solution for your project.

3D Rendering in Films

Maybe this Film industry (the so-called Show Biz) is the industry which has got the most impact of 3D rendering. Each year vast amount of animated movies are released featuring a Raccoon or a Panda or countless characters. We can see them in the best possible realistic way. Their body movement, their mouth movement, their expressions look nothing but real! Studios like Pixar, DreamWorks has changed the whole trajectory of animated entertainment including the motion-media canvas.

Back then in the 70s, computer-generated imagery was not realistic like today at all. But back then, after seeing the ‘Star Wars’, people got speechless. Their jaw dropped to their feet thinking, ‘How the hell did they do it!’ It was the first time when 3D rendering was used in a movie. It was the technology that no one had seen before. And then the evolution happened. Still one of the best hardcore director named Mr. Spielberg brought us ‘ Jurassic Park’ in 1993. And it became a world-class hit. People started to cope with the involvement of technology in a commercial movie. Then Hollywood came up with the ‘ T2: Judgement Day’. And we know what happened with that movie. Till now 3D rendering is doing its job done. It has nothing but the best to the movie industry so far and will go on amazing us!

Architecture and Design

Architecture has got a romantic touch with the help of 3D rendering. No doubt about that. The glamorous touch of it made the unreal make real. We are talking about architecture, isn’t it? Not a romantic story! Sorry, I lost the track (quink quink)!

Ok, picture a 50 storied building including it’s interior and exterior. Picture its wall, its decoration, its hallway, its room, and many many things. Not possible? It is possible by sketching a design of each fundamental things that a building can hold. But not in pictured mode, isn’t it? Before the involvement of 3D rendering in the architecture industry, architects, designers, and engineers came up with paper sketch based idea before their client. But with the romantic touch (!again) of 3D rendering services, designers can make that paper sketch design into photorealistic marvel that can be easily recognized by the clients. And if the client doesn’t want or like anything, just remove it and replace it with other pre-made material. 3D rendering is the best friend of an architect and designer. It makes them show the project, not tell them.
