Nvidia Research Turns 2D Photos into 3D Scenes (blogs.nvidia.com)

Article summary

NVIDIA Research has developed a technique called Instant NeRF, which can turn a collection of 2D images into a digital 3D scene in a matter of seconds. This is achieved through a process called inverse rendering, which uses AI to approximate how light behaves in the real world. The resulting 3D scene can be used in various applications, such as creating avatars or scenes for virtual worlds, capturing video conference participants and their environments in 3D, or reconstructing scenes for 3D digital maps. The technique has the potential to revolutionize the field of 3D capture and sharing.

What commenters say

• The ability to generate 3D scenes from 2D images has the potential to revolutionize the film and TV industry by allowing for dynamic addition of shots in post-production.
• Estimating camera angles and positions is a long-standing problem in computer vision that has been largely solved, making it possible to generate accurate 3D scenes from 2D images.
• The use of NeRFs may replace the need for photo-realistic modelers in some industries, but it will also create new opportunities for artists and designers.
• The quality of the generated 3D scenes is still limited by the quality of the input images and the complexity of the scene, which can result in artifacts and inaccuracies.
• The technique has the potential to be used in a wide range of applications, including virtual reality, architecture, and entertainment.
• The use of NeRFs may also enable the creation of highly realistic virtual sets and environments, which could be used in film, TV, and other industries.
• Some commenters are skeptical about the potential of NeRFs to replace traditional 3D modeling techniques, citing the need for high-quality input images and the potential for artifacts and inaccuracies.
• Others believe that NeRFs have the potential to enable new forms of creative expression and storytelling, particularly in the context of virtual reality and immersive media.
