[Huawei Developers] Mike-mei:
The HUAWEI DEVELOPER CONFERENCE 2022 (Together) kicked off on Nov. 4 at Songshan Lake in Dongguan, Guangdong, and showcased HMS Core 3D Modeling Kit, one of the critical services that illustrates HMS Core's 3D tech. At the conference, the kit revealed its latest auto rigging function that is highly automated, is incredibly robust, and delivers great skinning results, helping developers bring their ideas to life.

The auto rigging function of 3D Modeling Kit leverages AI to deliver a range of services such as automatic rigging for developers whose apps cover product display, online learning, AR gaming, animation creation, and more.

This function lets users generate a 3D model of a biped humanoid object simply by taking photos with a standard mobile phone camera, and then lets users simultaneously perform rigging and skin weight generation. In this way, the model can be easily animated.

Auto rigging simplifies the process of generating 3D models, particularly for those who want to create their own animations. Conventional animation methods require a model to be created first, and then a rigger has to make the skeleton of this model. Once the skeleton is created, the rigger needs to manually rig the model using skeleton points, one by one, so that the skeleton can support the model. With auto rigging, all the complexities of manual modeling and rigging can be done automatically.

There are several other automatic rigging solutions available. However, they all require the object to be modeled be in a standard position. Auto rigging from 3D Modeling Kit is free of this restriction. This AI-driven function supports multiple positions, allowing the object's body to move asymmetrically.

The function's AI algorithms deliver remarkable accuracy and a great generalization ability — due to a Huawei-developed 3D character data generation framework built upon hundreds of thousands of 3D rigging data. Most rigging solutions can recognize and track 17 skeleton points, but auto rigging delivers 23, meaning it can recognize a posture more accurately.

3D Modeling Kit has been working extensively for developers and their partners across a wide range of fields. This year, Bilibili merchandise (online market provided by the video streaming and sharing platform Bilibili) has cooperated with HMS Core to adopt the auto rigging function, allowing for virtually displaying products. This has created a more immersive shopping experience for Bilibili users through the application of 3D product models that can make movements like dancing.

This is not the first time Bilibili cooperated with HMS Core as it previously implemented HMS Core AR Engine's capabilities in 2021 for its tarot card product series. Backed by AR technology, the cards feature 3D effects and users are able to interact with the cards, which are well received by users.

3D Modeling Kit can play an important role in many other fields.

For example, an education app can use auto rigging to create a 3D version of the teaching material and bring it to life, which is fun to watch and helps keep students engaged. A game can use auto rigging, 3D object reconstruction, and material generation functions from 3D Modeling Kit to streamline the process for creating 3D animations and characters.

HMS Core strives to open up more software-hardware and device-cloud capabilities and to lay a solid foundation for the HMS ecosystem with intelligent connectivity. Moving forward, 3D Modeling Kit, along with other HMS Core services, will be committed to offering straightforward coding to help developers create apps that deliver an immersive 3D experience to users.
