Instructor: Lingqi Yan | UCSB Bilibili: https://www.bilibili.com/video/BV1X7411F744 Lectures covered: Lecture 10 (Geometry 1: Introduction), Lecture 11 (Geometry 2: Curves and Surfaces), Lecture 12 (Geometry 3)

Geometry is an extremely important yet difficult topic in computer graphics. This post covers various ways to represent geometry (implicit and explicit), curves and surfaces (Bezier curves, B-splines, Bezier surfaces), mesh processing (subdivision, simplification, regularization) as well as the shadow mapping technique.

02 | Geometry and Primitives

Geometry is the building block of the 3D world. Master 5 basic primitives and you can combine almost any shape.

01 Learning Objectives

This lesson focuses on Three.js built-in geometries:

Master the constructors and parameters of 5 basic geometries
Understand the relationship between segments and vertex count
Learn to combine multiple primitives into complex objects
Understand Wireframe visualization principles
Learn procedural texture generation (Canvas)

02 The Nature of Geometries

Three.js geometries are essentially collections of vertex data:
