To help understand what 3D AI avatars are, we often use 3D characters from movies and games as a reference. However, we haven't fully explored their key differences.

Many people are curious:

In the world of virtual characters, what exactly are the similarities and differences between 3D avatars and 3D characters in film, animation and games, as well as virtual idols, which have been a big hit in the last few years;
In the AI space, how do 3D avatars relate to ChatGPT and real-world robots?

Today, let’s break it all down and explore what makes 3D avatars truly unique!

3D Avatars vs. 3D Animated Characters

First, both Hollywood blockbuster characters and avatars in AAA games , similar to 3D avatars, feature highly realistic appearances and fluid movements. Before discussing their differences, let’s introduce an important concept—PGC.

What is PGC?

PGC stands for Professional Generated Content, referring to content produced by professionals with specialized skills and experience. This includes content created by media institutions, game studios, animation companies, and film production teams.

3D characters in movies and games are all produced under the PGC model.

It seems simple to let 3D characters talk and move, but what hides behind is massive investments of time, talent, and money. The higher the quality of the character, the longer the production cycle and the more expensive it becomes, while highly skilled professionals remain in limited supply.

Character Design: The process involves character designers, concept artists, 3D modelers, and rigging specialists using software like Maya or Blender. Just creating a high-quality 3D character’s face alone can cost $70,000 or more, and it takes a small professional team several months to complete the full workflow, from concept art to face modeling and rigging.
Animation: Animators must use industry-leading 3D animation software like Maya to create smooth character movements frame by frame. Even a senior 3D animator can only produce 1-2 seconds of high-quality animation per day.
Voice Acting: Professional voice actors, sound engineers, and post-production teams work in high-end recording studios to bring 3D characters to life with realistic speech.

If you aren’t familiar with 3D modeling or animation, chances are you haven’t even heard of many of these tools—let alone know how to use them.

Wouldn’t it be amazing if you could instantly have all these capabilities at your fingertips?!

Rendora’s AI-Powered 3D Avatars: Making High-Quality 3D Characters Accessible to Everyone

In the past, only industry professionals could painstakingly create 3D characters. Now, 3D avatars combined with AIallow anyone to create high-quality, professional 3D characters with zero barriers—making it accessible to users from all industries.

Key Takeaway: Breaking free from the PGC model, Rendora's 3D AI avatars are now accessible to everyone.

3D Avatars vs. Virtual Idols

The concept of virtual idols originated in Japan and refers to virtual characters created using animation technology and artificial intelligence. These characters are often highly personalized in terms of their appearance and voice.

For example, Hatsune Miku is a classic virtual idol. Not only does she have a rich portfolio of music, but she also holds special concerts and has a wide range of merchandise.

Rendora's Avatar Livestreaming

The essential difference between virtual idols and 3D avatars is that virtual idols are typically designed for the entertainment industry, with specific character settings and backstories. They focus heavily on entertainment value and fan engagement. They can sing and perform, but they do not understand the real world and lack common sense and professional knowledge.

For example, virtual idols cannot answer your questions. They don't know why people go to work, they can't answer specific queries, and they cannot help you complete specific tasks.

Similar to 3D characters, virtual idols or corporate virtual IPs are also produced using the PGC model, and ordinary people can hardly complete production independently.

These virtual idols and IPs rely on professional teams to create their images and animations, or they use real-life motion capture to interact with audiences in live streams. However, without real human drivers, they cannot interact with users 24/7 or engage in 1v1 communication.

3D avatars are different! 3D avatars are more like your colleagues while virtual idols and IPs are like celebrities.

Let’s recap definition in previous articles: 3D avatars should be visually appealing, expressive, and highly capable.

They can not only create videos and live streams but also interact with each user in 1v1 text, voice, and video formats. Additionally, they possess professional skills, such as writing scripts, presenting on camera, and generating edited 3D avatar videos with just one click.

This means you can create your own 3D avatar, and treat him as a white-collar worker to help you complete tasks.

In the video production field, films, TV shows, and variety shows used to be produced by professional studios. However, with the development of mobile devices and the internet, the popularity of short video platforms and editing software has made it possible for everyone to create short videos and live streams. The content has shifted from PGC long-form videos to UGC short videos and live interactions.

In the past, only professionals could create 3D characters and animations, which were confined to professional content like films and games. Now, with the development of 3D avatars and AIGC, along with products like Youyan that revolutionize traditional video production methods, 3D video has already entered the UGC and AIGC era.

It's the same with 3D content. In the past, only professionals could create 3D characters and animations, which were confined to professional content like films and games. Now, with the development of 3D avatar and AIGC, along with products like Rendora that revolutionizes traditional video production methods, 3D video creation has already entered the UGC and AIGC era.

If the upgrade of long-form video technology allowed 3D movie characters created by directors to appear on the big screen, then virtual idols are products of the social media era. Virtual idols created by entertainment companies, Multi-Channel Networks(MCNs), and influencers can thrive on mobile screens, while 3D avatars further lower the barrier to content creation. Everyone can use 3D avatars on various auditoriums and stages, anytime and anywhere.

Key takeaway: 3D avatars are UGC and AIGC, and can 1v1 interact online 24/7 .

3D Avatar vs ChatGPT

Having talked about 3D characters and virtual idols, let’s now look at the AI field.

Taking the familiar ChatGPT as an example, chatbot programs such as ChatGPT are capable of providing text and voice conversations.3D avatars have the same text-to-text and text-to-speech capabilities.

In fact, ChatGPT is also a type of avatar. It has the ability to express itself—you can see its text and hear its speech, but you cannot see its image or visual outputs, such as expressions, movements, and eye contact.

This is because chatbots themselves do not have a physical image and cannot move to interact with you.

Even so, there are still people making up the image of ChatGPT. For example, some people use ChatGPT to simulate man-machine love scene in the movie Her. And a blogger gained millions of fans through flirting dialogues with ChatGPT DAN mode. In fact, a lot of people have begun to imagine that “DAN” is a handsome bossy president.

The emergence of 3D avatars is turning fantasy into reality. Characters like Her and Dan can now easily have beautiful and handsome appearances respectively.

3D avatars can provide chatbots with high-quality visual appearances. You can choose your preferred style, customize facial features, change makeup, and clothing accessories, and see their vivid facial expressions and body movements, fulfilling all your imaginative desires.

Over the past decade, the content industry has evolved from text and images to video and live streaming. In the AI era, more efficient information exchange through video and live streaming content will also become the mainstream of AIGC content.

To some extent, 3D avatars are an upgrade to chatbots like ChatGPT, and they represent the ultimate form of AIGC.

With the development of AR and AI technologies, users' demand for 3D visual content will continue to increase. AI products that only have text-to-speech, text-to-text, and text-to-image capabilities are far from enough. Only 3D avatars that are visually appealing, expressive, and highly capable and able to integrate AI-generated text, speech, and animation, can more effectively meet users' content demands.

Key takeaway: 3D avatars are the ultimate form of AIGC.

3D avatars vs Robots

In addition to ChatGPT, AI robots have already integrated into various aspects of daily life, playing the role of blue-collar workers.

For example, a vacuum robot can take on the role of a cleaner, helping you clean the floor. A robotic cooking machine can perform the job of a chef, helping you cook and prepare meals. Automated sorting robots can quickly sort parcels, improving logistics efficiency. If robots are the AI version of blue-collar workers in life, then 3D avatars are the AI version of white-collar workers in the workplace.

3D avatars can take on roles like teachers, lawyers, trainers, marketing managers, hosts, and HR personnel, excelling in knowledge-based jobs.

For example, 3D avatars can be hosts, effortlessly handling various events and press conferences. 3D avatars can be your legal advisors, answering legal questions online. 3D avatars can also become teachers, explaining various knowledge from kindergarten to university, always maintaining high quality lectures.

3D avatars vs Real Humans

At this point, what is the difference between 3D avatars and real white-collar workers?

Apart from the fundamental difference between humans and AI, 3D avatars have two key characteristics: firstly, as mentioned earlier, they can interact with users 24/7 and in a 1v1 manner; secondly, they can scale up efficiently.

No one can work 24 hours a day, 7 days a week, all year round, but 3D avatars can.

No one can appear in multiple places at the same time and have face-to-face conversations with thousands of people, but 3D avatars can.

More importantly, 3D avatars can easily scale up by dozens or even hundreds of times.

Almost no company can hire 100 employees meeting business needs from various countries in a single day, but 3D avatars can.

If you need a host, you can customize different 3D avatars based on the theme of the event, create them into videos or live streams, and interact dynamically in real-time based on the live streaming needs.

Key takeaway: 3D avatars can scale up efficiently.
