With the rapid development of 3D movies in recent years, VFX movies have also received more and more attention. From the point of view of the box office of European movies, the top 5 movies Avengers: Endgame, Avatar, Titanic, Star Wars: The Force Awakens, Avengers: Infinity War. They are almost inseparable from VFX production. And Disney relied on the 3D animated film Frozen series, sweeping $ 2.574 billion in the world, creating a new record for the global animated film box office.

Why do you need to use a render farm? Rendering is indispensable behind these movies, and rendering is almost done by various render farms of all sizes.

Rendering is the later part of 3D animation production, and rendering is a very time-consuming step in the later stage. An 80-minute animated movie can often be rendered in thousands to tens of thousands of hours.

In the animated film COCO, 29,000 lights were used in the scene of the train station; 18,000 lights were in the cemetery; 2000 RenderMan practical lights were used in the Undead World. The production team used the RenderMan API to create 700 special point cloud lights, which expanded to 8.2 million lights. These massive lights are a nightmare for the rendering artist. For the production requirements, the test can not complete such a huge rendering. They once tested rendering and found that these light-filled shots actually took 1,000 hours per frame! They continued their research and shortened it to 125 hours and 75 hours. The rendering time of one frame at the time of final production was 50 hours and one frame. The movie is 24 frames per second, 1440 frames per minute, if a movie is calculated as 90 minutes. That 1440 frames 90 minutes = 129600 frames, 129600 50 = 6480000 hours. Converted into adulthood is 740 years?

"To render Avatar, Weta Digital used a 10,000-square-foot server farm. There are 4,000 servers with a total of 35,000 processor cores. The average time to render a single frame is 2 hours, 160 minutes of video. The overall rendering time takes 2880000 hours, which is equivalent to 328 years of work for one server! "

If the rendering work is only on a general computer, this is almost impossible. So the production team created its own render farm, powerful machine performance and huge number to complete such a huge amount of work.

For small teams, studio, freelancer, and individual producers, rendering take the same time. If they want to spend a lot of time using the computer for rendering work, this is undoubtedly a time-consuming thing, and they are unacceptable. These various reasons, coupled with uncontrollable factors such as computer crashes, special effects artists often cannot complete the work within the time specified by the producer due to rendering problems. Moreover, the labor, material, and electricity required to maintain computer rendering. The cost is also a big fee for the production company!

So it is very necessary to work with some render farms. Not only can it save the time of the production staff, but also can use a large number of machines in a limited time to complete the work in a short time.

The emergence of cloud rendering technology makes the render farm more mature. Cloud rendering is to upload materials to the cloud and use this cloud computing system of the rendering company to render remotely.

Another advantage of cloud rendering is that small studios can also be responsible for rendering high-quality materials. In the film industry, this technological change is no less than the change that cloud computing itself brings to the IT industry.

Taking Fox Renderfarm as an example, no matter where the special effects technician is, they can use cloud rendering services to complete the "trilogy": 1. Upload your project; 2. Wait for the rendering to complete; 3. Download to the local machine. In addition, they can call more machines according to their urgency, and they can arrange the order of rendering and monitor the progress of rendering at any time. At the same time, the price is relatively low, which is accepted by many film and television special effects companies, rendering studios, and individual designers. So, why not have a free trial on Fox Renderfarm now? to experience the amazing cloud rendering services to speed up your rendering.

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.
