What is Rendering? How to Accelerate the Rendering Speed?

Server Fox Renderfarm

In order for 3D projects to be displayed visually at all, they have to be rendered. Although this process is done by computer processors, this work step is very time-consuming due to the enormous computing power.

But what exactly happens when rendering? To put it simply: A finished single image or an entire scene from moving images is calculated pixel by pixel from the raw data of a 3D model previously created in a corresponding program. In the case of moving images, one must also note that one second of the finished scene consists of several “frames”. For a movie, for example, that's 24 frames per second. And when rendering, each individual frame is calculated as a single image.

The duration of the calculation of these frames are depending very much on the quality and the level of detail of the project, but above all on the set lighting conditions and the corresponding surface reflections, the given perspective and of course any errors that may be contained. In the end, the calculations are extremely complex and result from the previous work steps such as modeling, texturing, shading, lighting and animation. And so rendering is also the last big step in the implementation of a 3D project.

600 Years of rendering time for a character from "The Load of the Rings"?

To give you an idea of what that means in practice: In the 2003 Oscar for the best visual effects film "The Lord of the Rings: The Two Towers", the character "Treebeard" - an animated tree creature - was in the long version can be seen for 13:45 minutes. This means that a total of 19,800 frames (i.e. single images) had to be rendered. In this figure, the calculation of a single frame took about 48 hours, which in turn means a total of 950,400 calculation hours for all frames together. That would be the equivalent of 39,600 days or over 600 years for a single computer processor.

No wonder, then, that the executing VFX studio Weta Digital increased the already enormous technical equipment of around 2,250 processor cores by another 500 while production was still running. In the end, with this concentrated computing power, rendering “Treebeard” alone should have taken about 14 days. But the long version of the film lasts almost four hours and consists of a lot of animated content. It's hard to imagine how long it must have taken to render the entire movie. And mind you, this does not even include the artistic work, only the calculation is finished images.

60 Million rendering hours for the Disney film "Frozen"

But whoever thinks that rendering will be accelerated by technological developments is only partially correct. Because the developing technological possibilities naturally also improve the quality of the projects. The production team of the world-famous Disney animation film "Frozen" from 2013 cope with a total of 60 million rendering hours. And although the Walt Disney Animation Studios had increased the number of processor cores from 5,300 to 30,000 within two years and thus had one of the world's largest data centres, rendering the entire film still took over 83 days with all the computing power 24 hours without a break. But Disney doesn't just work on one project, so it probably took longer. And another small comparison: Incidentally, a single supercomputer from this time would have taken more than 900 years to render the film ...

These are of course examples from professional productions with the highest standards. And of course, for you and your studio, how to accelerate the rendering speed? The best cloud rendering service provider, Fox Renderfarm with enormous computing power worth choosing. Fox Renderfarm was founded in 2011 and is now the largest provider in this area in Asia.

What is the Difference Between 2D and 3D Model Rendering?
What is the Difference Between 2D and 3D Model Rendering?
2D Model Rendering2D model rendering as a process has evolved considerably in modern history. Before the advent of 3D model rendering, the process was undertaken entirely by 2D artists (technical draftsmen or creative designers) whose job it was to project life, despite the limitations of pencil and paper.!What is the difference between 2D rendering and 3D rendering 2 Restricted ViewsPerhaps the most obvious limitation is that every aspect of the 2D model is limited to the 2D plane. Although creative license can be used here, accuracy is key.Although rendering a model in 2D is not directly related to mathematics, it is completely relevant to it. It applies to symmetry and shape. Perspective and line strength play an important role in generating high quality 2D rendered images, for example when designing architectural illustrations. Understanding basic perspective and line values is the difference between an average rendering and a good one. In addition, there is no opportunity to change perspective, as this requires changing the camera field of view, which is only possible when modeling in 3D. Easy Insertion of 2D AssetsHowever, not every 2D model rendering is hand-drawn. Some assets may actually be cropped or repurposed from real images sent by the client or their photographer, such as high-quality photographs of display furniture or accessories superimposed on a display board. Photoshop often plays an important role in such processes. Fewer Considerations when Making AdjustmentsAnother difference between 2D model rendering and 3D model rendering is that with 2D, the artist is able to create the illusion of perfect perspective while maintaining direct control over the image, without having to change any of the complexities associated with 3D rendering. PriceSo why does a two-dimensional service still exist in the industry? It's cost effective. Not every potential client has the budget required to outsource 3D models. As a result, many design firms have made themselves available to meet the demand for simpler renderings at very affordable prices. 3D Model Rendering!What is the difference between 2D rendering and 3D rendering 3When handled correctly, 3D model rendering can provide a near-perfect photograph of any scene, giving a realistic reproduction of the scene. This helps your clients to better understand every nuance of the space and helps them to understand exactly how to place items in it, or you can use 3D modeling software and make quick changes to suit their whims. Limitations of Pre-built 3D LibrariesIt can be slightly challenging if some of the assets in the pre-built 3D library are not easily accessible or difficult to build independently. This means that the designer may end up having to readjust a 3D model that differs from the client's requirements. That said, there is an advantage in this that 2D cannot offer: the ability to build your own library of furniture, environments and accessories that can be easily reused for future projects. Adjustable ViewpointIn addition to providing accurate and wide viewing angles, aesthetically pleasing camera angles and even software for digital flight, it provides a broader overall appearance of the model for 3D images. There is no problem with the accuracy of the angles when positioning the camera in the desired position. They are positioned mathematically. The rendered image is modeled from the computer and you do not need to be concerned with the framing or any detail in the image. The rendering, based on an iteration or sample of the output, will determine the focus of the detail covering each pixel of the image.Another important feature of 3D model rendering is the resulting high quality depth - 3D provides a clear view anywhere within the camera's field of view. Vivid ResultsWhen making full use of 3D rendering software, the lifelike effects are often indistinguishable from real photographs. The renderings are often convincingly realistic and look very satisfying, as the more realistic shadows and natural light are difficult to emulate with 2D illustrations. Is 2D or 3D Model Rendering Suitable for your Client's Project?!What is the difference between 2D rendering and 3D rendering 4Both have their advantages and disadvantages, but these differences can also make it easy for clients to choose the service they want to pursue. As with any project, there are many factors to consider beyond cost.If your client is more of a traditionalist looking for the visual appeal of a more classic illustration, then drawing 2D images may be the most appropriate option.If your client has a penchant for realism, then you may prefer to use a 3D presentation.2D model rendering is best suited to artists who can effectively convey space and depth. But of course, it is not for everyone. Some artists do not have the ability to visually communicate spatial differences, so mastering 3D model rendering can definitely help any professional to meet the needs of their clients and effectively communicate the vision of their project to all stakeholders.As a designer or illustrator, it is important to gain insight into your client's mind by showing as much diversity as possible in your portfolio to help you understand what they find attractive. If your clients respond more positively to 3D images than 2D, you should do your best to adapt to their sensibilities. Even if your skills lie primarily in one or the other, you should always try to improve your toolkit to meet the changing needs of today's customers.
