Virtual worlds

NVIDIA’s new AI model quickly generates objects and characters for virtual worlds

seeks to simplify the creation of virtual 3D worlds with a new model. GET3D can generate characters, buildings, vehicles and other types of 3D objects, says NVIDIA. The model should also be able to create shapes quickly. The company notes that GET3D can generate around 20 objects per second using a single GPU.

The researchers trained the model using synthetic 2D images of 3D shapes taken from multiple angles. NVIDIA claims that it only took two days to feed around 1 million frames into GET3D using A100 Tensor Core GPUs.

The model can create objects with “high-fidelity textures and intricate geometric detail”, NVIDIA’s Isha Salian . The shapes made by GET3D “are in the form of a triangular mesh, like a papier-mâché model, covered with a textured material,” Salian added.

Users should be able to quickly import the objects into game engines, 3D modelers and movie renderers for editing, as GET3D will create them in compatible formats. This means it could be much easier for developers to create dense virtual worlds for games and the metaverse. NVIDIA cited robotics and architecture as other use cases.

The company said that based on a set of car imaging data, GET3D was able to generate sedans, trucks, race cars and vans. It can also produce foxes, rhinos, horses, and bears after being trained on animal pictures. As you would expect, NVIDIA notes that the larger and more diverse the training set provided to GET3D, “the more varied and detailed the output.”

With the help of another NVIDIA AI tool, , it is possible to apply different styles to an object with text prompts. You can apply a burnt-out look to a car, convert a house model into a haunted house, or, as a video showing off the technology suggests, apply tiger stripes to any animal.

The NVIDIA Research team that created GET3D believes that future versions could be trained on real-world images instead of synthetic data. It may also be possible to train the model on different types of 3D shapes at once, rather than having to focus on one category of objects at any given time.
