With the development of emerging technology- 3D rendering , the quality of interactive applications has been greatly improved. Immersive digital experiences created with real-time 3D rendering software are virtually indistinguishable from reality. As technology improved over time, it became easier to render 3D images on less expensive personal workstations, requiring less input from designers.
What is real-time 3D rendering? how it works
Simply put, real-time 3D rendering allows users to view or interact with 3D images and scenes that simulate real-time motion.
Live imaging allows for more comprehensive visualization of ideas and designs, including how they will be experienced in action. 3D rendering also allows for greater collaboration and innovation between designers and marketing teams. This kind of workflow has only recently been possible because many people used to be required to work on local render farms, and the processes required to maintain and manage these farms took even more time and money.
It can be said that 3D rendering is a multi-step process, and the graphics content is a two-dimensional image generated based on the three-dimensional scene using software. Real-time 3D rendering means you digitally build a model that can be rotated and turned. So it's not a matter of showing a static three-dimensional image, it's possible to rotate the model and see it from all different angles. Unlike still image rendering, you can use real-time rendering to make modifications to your model and see the results directly on the screen.
To give a more technical explanation, you can say that a three-dimensional image of a product is made up of triangles. You create a model of a triangle, you do it one triangle at a time, placing them in a specific position (width, depth and height). There are also shortcuts so you can make many polygons quickly instead of placing them one at a time. Finally, you have a model consisting of hundreds, thousands, or hundreds of thousands of triangles. For example, if you want to create a moving box, it is a simple model that only has 6 sides when it is closed. Then you use 12 triangles. If you want to create a sofa with many soft, rounded edges, you will need to add more triangles to be able to create the soft shape of the sofa.
There are also many different lighting techniques that allow you to create a stylish and realistic reproduction of your sofa. The more technology advances, the more you can compare lighting in 3D to real-life lighting and the way light works. An important part of creating photorealistic images is dealing with reflections by adjusting light and shadows. Shadows are created where light cannot reach. How an object is illuminated is important to the result. Reflections occur depending on how light falls on an object. The intensity of light and the surface of the object play important roles.
In what industries can 3D rendering be applied?
A simpler way to measure the importance of an emerging technology like real-time 3D rendering is to look at which industries it has changed and which industries are about to adopt this new technology. For now, real-time 3D rendering has changed some industries.
1. Game industry
As one might expect, one of the biggest industries that relies on this technology is gaming. Real-time 3D rendering makes game development easier, faster, and cheaper, which is great news for game creators. However, the bigger draw may lie with gamers, as streaming is the most exciting application of this technology.
Meta, Microsoft, and Google are fighting tit for tat, competing for the cloud gaming market and becoming the first to dominate it. Many speculators believe that the days of physical cartridges are over and that AR/VR and cloud-based user storage are the future of gaming. It shouldn't come as a surprise that they're investing heavily in conquering the 3D rendering space.
2. Automobile industry
With the advent of real-time 3D rendering, digital showrooms have become an essential step in the sales process. Users can see what the car looks like inside and out in real time, such as small details of the vehicle, seat color or material from any angle, and more. The virtual showroom created by 3D rendering software can replace the real showroom, providing designers and customers with what the car will look like in the actual environment. In the future, car buyers will be able to customize their vehicles exactly how they want them to look.
3. Architectural Visualization/Real Estate
Previously, architects and developers could only use hard drive copies of blueprints and miniature 3D models made from foam core to help clients visualize a building project. Now with real-time three-dimensional rendering, the company can digitally recreate a site, and users can experience the various interiors of the house and the scenery in front of the windows in virtual reality , giving buyers a more accurate understanding of the home.
4. Media/Entertainment
Like games, film and television production have always been at the forefront of new visualization technologies. People are pursuing higher-definition visual effects, which means that the resolution of graphics needs to be continuously improved. Even sports broadcasts use rendering software like Unreal Engine to combine live footage and on-screen images with motion tracking to add a new entertainment experience for fans.
real-time rendering software
When it comes to high-quality rendering, it's possible to create interactive applications that look like video games. There are various 3D engines available, depending on what you want to achieve. The most famous of these is Unreal Engine, an advanced 3D engine that delivers incredible photo-realistic experiences.
Unreal Engine is a game engine developed by Epic Games, which is also the driving force behind several well-known video games, such as Fortnite. Unreal Engine is a very popular game engine that you use when you want to display a product with very high fidelity. For example, with high-quality visualization of cars, users can accurately see the different shine levels of the car's paint under light from different angles, as well as the detailed display of different materials inside the car.
Cloud virtual display is beginning to become a new display method. It uses cloud computing resources and uses ultra-high-definition, full-real-time, interactive, and immersive online virtual modes to break geographical space restrictions, realize lightweight terminal equipment, and meet more needs. Users can conveniently browse and customize configuration requirements, etc. 3DCAT real-time rendering cloud is based on the powerful graphics rendering computing power of the cloud, rendering XR applications and pushing them to the terminal in real time, providing users with a public cloud + private cloud real-time rendering solution.
3DCAT uses Cloud Streaming technology to realize 3D application interaction and real-time access. Cloud streaming technology is based on the concept of cloud computing, deploying applications to run in the cloud, and pushing the running results to various terminals (PCs, tablets, mobile phones, XR devices, etc.) in a "streaming" manner. solution. Users can interact with cloud applications in real time through terminals (browser, WeChat, APP, controller, voice, etc.), making the application experience more immersive. New users who register can get 30 real-time rendering experience coupons.
