Humanity has been exploring the depths of OpenAI’s ChatGPT neural network since early December. One developer got the AI dialog to spit out working AR code.
OpenAI’s ChatGPT dialog AI is optimized for generating texts and answering questions. But initial tests from early December quickly showed that there’s more to the system than just a few neatly worded sentences. Programming code, for example.
ChatARKit – AR app generated by ChatGPT
As a result, ChatGPT selects 3D objects from Sketchfab that match the voice command and places them on the desktop or floor as prompted. If you prompt it, ChatGPT even scales and rotates the 3D models. The AI system generates the code for this on its own.
These are some working sample prompts according to Trzynadlowski:
- “Place a cube on the nearest plane.”
- “Place a spinning cube on the floor.”
- “Place a sports because on the table and rotate it 90 degrees.”
- “Place a school bus on the nearest plane and make it drive back and forth along the surface.”
Trzynadlowski makes his ChatGPT AR app available for free as open source on Github.
Generate 3D objects in VR with natural language
For VR, developer Jasmine Roberts recently demonstrated an implementation of OpenAI’s new 3D AI Point-E: like the image AI DALL-E 2, it can generate content based solely on text input. Instead of images, however, Point-E generates 3D point clouds that represent a 3D model. Per generation, Point-E takes only about one to two minutes on a single Nvidia V100 GPU. Roberts’ demo runs in real time.
Point-E is a starting point for OpenAI for further work in text-to-3D synthesis. Google with Dreamfusion gold Nvidia with Magic3D also recently introduced text-to-3D systems, which could play an important role in the further spread of 3D content – a fundamental assumption of the metaverse thesis – in the future.
