Methodology Our rendering pipeline uses 3D triangles as primitives, each defined by three learnable 3D vertices, color, opacity, and a smoothness parameter \( \sigma \). The triangles are projected onto the image plane using a standard pinhole camera model with known intrinsics and extrinsics. Instead of binary masks, we introduce a smooth window function that softly modulates the triangle's influence across pixels. This function is derived from the 2D signed distance field (SDF) of the triang

Having your compile-time cake and eating it too Disclaimer In this post, I assume: You know a little bit about Rust. You know a little bit about Zig. I'll be using my own syntax to express ideas from both of these languages. Why "types are just values" doesn't work As programmers, we like it when our programs run well. Type systems are there to help us with that. They track the types of values in our programs before we run them, which not only saves us from runtime crashes but enforces g

A short note on two related rules of thumb. If there’s an if condition inside a function, consider if it could be moved to the caller instead: fn frobnicate (walrus: Walrus) { ... } fn frobnicate (walrus: Option <Walrus>) { let walrus = match walrus { Some (it) => it, None => return , }; ... } As in the example above, this often comes up with preconditions: a function might check precondition inside and “do nothing” if it doesn’t hold, or it could push the task of precondition checking to its

And each time I tried to learn how they work, I'd give up pretty quickly. But eventually, I got there. And once I finally understood how decorators work, my reaction was, "Is that it?"

A myth When fitting a non-linear model using linear regression, we typically generate new features using non-linear functions. We also know that any function, in theory, can be approximated by a sufficiently high degree polynomial. This result is known as Weierstrass approximation theorem. But many blogs, papers, and even books tell us that high polynomials should be avoided. They tend to oscilate and overfit, and regularization doesn’t help! They even scare us with images, such as the one belo
