Instant NeRF 3D Models: What's the big deal?

Updated: Sep 19, 2023

Neural Radiance Field (NeRF) is a type of neural network that can be used to represent and render realistic 3D scenes based on a collection of 2D images. NeRFs are trained on a set of images that have been taken from multiple viewpoints of the same scene. The neural network learns to associate each pixel in the images with a point in 3D space. This allows the neural network to generate new views of the scene from any angle.



NeRFs have a number of advantages over traditional methods of 3D scene representation. They are able to represent complex scenes with a high level of detail, and they can be used to generate new views of the scene in real time. This makes NeRFs well-suited for a variety of applications, such as virtual reality, augmented reality, and 3D printing.



Here are some of the benefits of using NeRF 3D:



  1. High-quality 3D models: NeRF 3D can be used to create high-quality 3D models of objects and scenes. These models can be used for a variety of purposes, such as virtual reality, augmented reality, and 3D printing.

  2. Real-time rendering: NeRF 3D can be used to render 3D models in real time. This makes it possible to create interactive 3D experiences that can be used for games, simulations, and other applications.

  3. Efficient data storage: NeRF 3D can be used to store 3D models in a compact format. This makes it possible to store large amounts of 3D data in a small amount of space.

  4. NeRF 3D is a promising new technology that has the potential to revolutionize the way we interact with 3D content. With its ability to create high-quality 3D models, real-time rendering, and efficient data storage, NeRF 3D is well-suited for a variety of applications.







NeRF and photogrammetry are two different methods for creating 3D models from 2D images. NeRF is a machine learning technique that uses artificial neural networks to learn the relationship between the 2D images and the 3D scene. Photogrammetry, on the other hand, is a more traditional method that uses geometric techniques to reconstruct the 3D scene from the 2D images.



NeRF has a number of advantages over photogrammetry. It can create more realistic 3D models, and it can do so with fewer images. NeRF is also more efficient, as it can generate new views of the 3D scene in real time. However, NeRF is a newer technology, and it is not yet as widely available as photogrammetry.


Photogrammetry has a number of advantages over NeRF. It is a more mature technology, and it is more widely available. Photogrammetry can also create 3D models of objects that are not well-suited for NeRF, such as transparent objects or objects with complex textures. However, photogrammetry can be more time-consuming and expensive than NeRF.


In general, NeRF is a better choice for creating realistic 3D models of objects with simple textures. Photogrammetry is a better choice for creating 3D models of objects with complex textures or objects that are not well-suited for NeRF.


Here is a table that summarizes the key differences between NeRF and photogrammetry:
