A neural network is trained to model the colour and density information of a scene, enabling the generation of realistic 3D representations. NeRFs are.
How NeRF works
Training the neural network
NeRF is based on a neural network that is trained to model the color and density information of a scene. This is done by inputting multiple 2D images of a scene from different angles. The neural network learns how light rays are emitted from different points in the scene and thus models the scene in 3D.
Representation and Rendering
Once trained, the neural network can be used to generate new views of the scene. This is done by interpolating the learned information to calculate color and density at each point in space. The result is a realistic 3D representation that can be viewed from any perspective.
Applications of NeRF
Augmented and Virtual Reality
In AR and VR, NeRFs enable the creation of immersive environments that are more realistic and detailed than ever before. This not only improves the visual quality, but also the overall user experience.
Digital twins
NeRFs can be used to create digital twins of physical objects or environments. These digital replicas can be used in various fields, such as manufacturing, construction or real estate, to optimize processes and save costs.
Future prospects
Neural Radiation Fields are an exciting and rapidly growing area of research. With further advances in the technology and underlying algorithms, NeRFs could soon find even broader applications and fundamentally change the way we create and use 3D imagery.
