Neural Radiance Field

Neural Radiance Field (NeRF), you may have heard this word many times in the past few months. Yes, this is the latest progress in neutral work and computer graphics. NeRF represents a scene with a learned, continuous volumetric radiance field \(F_{\theta}\) defined over a bounded 3D volume. In Nerf, \(F_{\theta}\) is a multilayer perceptron (MLP) that takes as input a 3D position \(x=(x,y,z)\) and unit-norm viewing direction \(d=(d_x,d_y,d_z)\), and produces an output which contains density \(\sigma\) and color \(c=(r,g,b)\). By enumerating all possible positions and directions of a bounded 3D volume, we are able to obtain the 3D scene.

My House Search in 2021

This post is my review of house search from Sep to Oct of 2021. I have checked 88 houses and most of which I have paid a visit. I was looking for a new house as my office has been moved to north and the long commute from my current house makes me to move somewhere north. As a result, I mainly considered the area from Mountain View (north of 85) to Belmont.

Neural Lumigraph Rendering

Neural Lumigraph Rendering was accepted for CVPR 2021 Oral and best paper candidate. This paper proposes a method which performs on par with NeRF on view interpolation tasks while providing a high-quality 3D surface that can be directly exported for real-time rendering at test time. code is publically available.
