This post explains how to apply a bloom effect to specific objects in a Three.js scene using multiple EffectComposer instances and layers. By leveraging Three.js Layers, objects that require the bloom effect are isolated into a dedicated layer. A “bloom composer” renders only these objects wit...
Post-processing in Three.js is a technique used to enhance the visual quality of rendered 3D scenes by applying various effects such as bloom, depth of field, and glitch effects. These effects are added after the main rendering process, giving developers control over the final appearance of a ...
This post explains the mathematical principles and dynamics of elliptical orbits in celestial mechanics. To fully grasp how planets move and where they are at any given time, it begins by introducing the concept of planetary orbits as ellipses, following Johannes Kepler’s first law of planetar...
This article introduces Spherical Harmonics (SH) and explains their mathematical foundation and applications. It covers how SH functions are used to represent data on spherical surfaces, particularly in computer graphics, including 3D Gaussian Splatting field. The interactive demo allows users...
Until now, I’ve illustrated celestial bodies as a completely spherical shapes: Earth, Sun, and Saturn. They have enough gravity to form nearly smooth, spherical shapes. However, Phobos, one of Mars’ moons, has an irregular shape due to its low mass and weak gravity, which aren’t strong enough ...
