Google Creates AI That Turns Text Into 3D Objects
DreamFusion is an evolution of Dream Fields, a text-to-3d-image generator revealed by Google back in 2021. And like Dream Fields, DreamFusion creates its 3D images by combining a Neural Radiance Field (NeRF) — or a neural network that can create synthetic 3D scenes using partial 2D datasets — with a pre-trained text-to-image prompt model.
The twist? Unlike Dream Fields, which utilized OpenAI's CLIP technology as that latter pre-trained model, DreamFusion now uses its own: Imagen, Google's DALL-E 2 competitor.
So, basically, Google booted Elon Musk's OpenAI tech and figured out how to use its own. Keeping things in-house — smart.
It's unclear when DreamFusion — or whatever comes next — will be available to the public, though we can definitely see a number of applications already. Just think of the value to indie game developers alone! And according to Twitter, it's already been used to 3D-print a ghost eating a hamburger, so cheers to that.
