This article walks through creating a Rust physics engine by implementing collision detection using the Separating Axis Theorem, covering point extraction, vector math, projection, overlap checks, and handling both rectangle‑rectangle and circle‑square collisions with complete code examples.
This article explains the mathematical foundations of fractals, demonstrates how to use Canvas coordinate transformations and vector operations, and provides complete JavaScript code for drawing classic fractals such as the Koch snowflake, hexagonal snowflake, and a binary tree using recursive algorithms.
This article introduces the fundamentals of a game physics engine, covering the concept of engines, essential mathematics like vectors and calculus, TypeScript implementations for vector operations, and the integration of Newtonian mechanics such as mass, inverse mass, and basic object properties.
This article explains how to use simple shapes like circles and rectangles for fast 2D collision detection, reviews vector mathematics, provides a reusable Vector2d class with operations such as addition, subtraction, length, dot product and rotation, and shows concrete JavaScript code for circle‑circle, circle‑rectangle (both axis‑aligned and rotated) and rectangle‑rectangle collisions using AABB and OBB techniques.
