What is the Difference Between 2D and 3D Model Rendering?

As a designer, architect or CG artist, one of the most likely questions to arise when communicating ideas with clients is: What is the difference between 2D model rendering and 3D model rendering? In this article, the best CPU&GPU render farm, Fox Renderfarm will work with you to find the answer together.

What is the difference between 2D rendering and 3D rendering 1

2D Model Rendering

2D 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 Views

Perhaps 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 Assets

However, 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 Adjustments

Another 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.

Price

So 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 3

When 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 Libraries

It 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 Viewpoint

In 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 Results

When 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 4

Both 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.

Three Aspects to See the Differences Between GPU and CPU Rendering (2)
Three Aspects to See the Differences Between GPU and CPU Rendering (2)
The fast cloud rendering services provider and GPU & CPU render farm, Fox Renderfarm will still share with you the difference between GPU and CPU rendering. - Three Aspects to See the Differences Between GPU and CPU Rendering (1)") 2. The Magic Inside of CPU and GPUThe above picture origins from the NVIDIA CUDA document. The green color represents computing units, orange-red color represents storage units, and the orange color represents control units.The GPU employs a large number of computing units and an extremely long pipeline, with only a very simple Cache-free control logic is required. But CPU is occupied by a large amount of Cache, with complex control logic functionality and lots of optimization circuits. Compare to GPU, CPU’s computing power is only a small part of it.And that’s most of the GPU's work look like, large work load of computation, less technique but more repetitive computing required. Just like when you have a task of doing the number calculation within 100 for a hundred million times, probably the best way is to hire dozens of elementary school students and divide the task, since the task only involve repetitive work instead of highly-skills requiring. But CPU is like a prestigious professor, who is proficient in high-level of math field, his ability equals to 20 elementary students, he gets higher paid, of course. But who would you hire if you are Fox Conn’s recruiting officer? GPU is like that, accumulates simple computing units to complete a large number of computing tasks, while based on the premise that the tasks of student A and student B is not dependent on each other. Many problems involving large numbers of computing have such characteristics, such as deciphering passwords, mining, and many graphics calculations. These calculations can be decomposed into multiple identical simple tasks. Each task can be assigned to an elementary school student. But there are still some tasks that involve the issue of "cloud." For example, when you go to a blind date, it takes both of the parties’ willingness to continue for further development. There's no way to go further like getting married when at least one of you are against this. And CPU usually takes care of more complicated issue like this.Usually we can use GPU to solve the issue if it’s possible. Use the previous analogy, the speed of the GPU's computing depends on the quantity of students are employed, while the CPU's speed of operation depends on the quality the professor is employed. Professor's ability to handle complex tasks can squash students, but for less complex tasks with more workload required, one professor still can not compete with dozens of elementary students. Of course, the current GPU can also do some complicated work, which is equivalent to junior high school students’ ability. But CPU is still the brain to control GPU and assign GPU tasks with halfway done data 3. Parallel ComputingFirst of all, let's talk about the concept of parallel computing, which is a kind of calculation, and many of its calculation or execution processes are performed simultaneously. This type of calculation usually can divide into smaller tasks, which can then be solved at the same time. Parallel computing can co-process with CPU or the main engine, they have their own internal storage, and can even open 1000 threads at the same time.When using the GPU to perform computing, the CPU interacts mainly with the following:- Data exchange between CPU and GPU- Data exchange on the GPU In general, only one task can be performed on one CPU or one GPU computing core (which we usually call “core”) at the same time. With Hyper-Thread technology, one computing core may perform multiple computing tasks at the same time. (For example, for a dual-core, four-thread CPU, each computing core may perform two computing tasks at the same time without interruption.) What Hyper-thread do is usually double computing core’s logical computing functionality. We usually see that the CPU can run dozens of programs at the same time. In fact, from a microscopic point of view, these dozens of programs are still dependent and serial computing supported, such as on four-core and four-thread CPU. Only four operations can be performed at a time, and these dozens of programs can only be executed on four computing cores. However, due to the fast switching speed, what is shown on the macroscopic is the superficial fact that these programs are running “simultaneously”.The most prominent feature of GPU is: large numbers of computing cores. The CPU's computing core is usually only four or eight, and generally does not exceed two digits. The GPU computing core for scientific computing may have more than a thousand calculation cores. Due to the huge advantage of the number of computing cores, the number of computations that the GPU can perform far outweighs the CPU. At this time, for those calculations that can be performed in parallel computing, using the advantages of the GPU can greatly improve the efficiency. Here let me explain a little bit of the task's serial computation and parallel computation. In general, serial computing is doing the calculation one by one. In parallel computing, several parallel computing is to do it simultaneously. For example, to calculate the product of real number a and vector B=[1 2 3 4], the serial calculation is to first calculate a*B[1], then calculate a*B[2], then calculate a*B[3], and finally calculate a*B[4] to get the result of a*B. The parallel calculation is to calculate a*B[1], a*B[2], a*B[3], and a*B[4] at the same time and get a *B results. If there is only one computing core, then four independent computing tasks cannot be executed in parallel computing, and can only be calculated in serial computing one by one; But if there are four computing cores, four independent computing tasks can be divided and executed on each core. That is the advantage of parallel computing. Because of this, the GPU has a large number of computing cores, and the scale of parallel computing can be very large, computing problems that can be solved by parallel computing, which showing superior performance over CPU. For example, when deciphering a password, the task is decomposed into several pieces that can be executed independently. Each piece is allocated on one GPU core, and multiple decipher tasks can be performed at the same time, thereby speeding up deciphering process.But parallel computing is not a panacea, it requires a premise that the problems can be executed in parallel computing only when they are able to be decomposing into several independent tasks, which many of them are not able to be decomposed. For example, if a problem has two steps, and the second step of the calculation depends on the result of the first step, then the two parts cannot be executed in parallel computing and can only be sequentially executed in sequence. In fact, our usual calculation tasks often have complex dependencies that can not be parallel computed. This is the big disadvantage of the GPU.About GPU programming, there are mainly the following methods: Fox Renderfarm hopes it will be of some help to you.

Linux’s Place in The Film Industry
Linux’s Place in The Film Industry
In 1991, a student named Linus Torvalds began developing a new operating system as a hobby. That hobby, which would later be called Linux, forever changed the world of computers. Since Linux is open source, anyone can license it for free and modify the source code to their liking. This has made Linux one of the most popular operating systems in the world.Linux is everywhere. The web server maintaining this page is very likely Linux based. You may have a version of Linux in your pocket right now. Google’s Android operating system is a modified version of Linux. Several world governments use Linux extensively for day to day operations. And, many would be surprised to learn that Linux has become the standard for major FX studios.In the early 90s, Hollywood studios relied on SGI and its Irix operating system to run animation and FX software. At the time, Irix was one of the best systems available for handling intense graphics. But a change was about to sweep through the computer industry. Windows began to dominate the business world, and Intel began making powerful chips at a lower price point. These market forces made expensive SGI systems hard to justify.When studios began looking for a system to replace Irix, Windows wasn’t an option due to its architecture. The proprietary software in place at many studios was written for Irix. Since Irix and Linux were both Unix based, porting that software to Linux was easier than porting to Windows. Render farms were the first to be converted. In 1996, Digital Domain was the first production studio to render a major motion picture on a Linux farm with Titanic. DreamWorks, ILM, Pixar and others quickly followed. Workstations were next for Linux once artists realized the performance boost in the new operating system. Under pressure from studios, commercial software vendors got on board and started releasing Linux compatible versions. Maya, Houdini, Softimage and other popular 3D applications quickly became available for Linux.By the early 2000s, most major studios were dominated by Linux. While Windows and Mac environments are still used for television and small independent films, practically all blockbuster movies are now rendered on Linux farms.Linux has many advantages for render farm. The obvious benefits are cost and customization. Since Linux is free to license, startup costs are greatly reduced compared to commercial systems. And, since Linux is open source, completely customized versions of the operating system are possible.There are other advantages. Linux machines can multitask well and are easy to network. But the single greatest advantage is stability. Unlike other operating systems, Linux doesn’t slow down over time. It is common for Linux machines to run for months, yes months, without needing a reboot.With all these advantages, it’s surprising to learn many online render farms still haven’t embraced Linux. While a handful of farms like Rebus, Rendersolve and Rayvision support Linux, Windows is still the most common environment for cloud rendering services.It’s not likely anything will replace Linux’s role in the film industry soon. Studios are heavily invested in Linux with millions of lines of custom code. While anything is possible, it would take another industry change akin to the PC revolution to shake Linux from its place in Hollywood.The story of Linux is almost like a Hollywood movie itself. It shows us that anything is possible. It’s hard to believe that a simple student project forever changed the world of computers and became the backbone of the film industry.
