Constructive Solid Geometry is a technique that has various use cases, ranging from quickly blocking out levels in a level editor to building generic 3d procedural geometry. Previous algorithms scale poorly and have reliability issues. This presentation will explain in detail how to implement a unique algorithm that allows you to perform hierarchical Constructive Solid Geometry in real-time on thousands of primitives.


Attendees will learn how to implement a Constructive Solid Geometry algorithm that will be robust, fast and scalable3

Intended Audience

Indie and tool developers, and anyone who is interested in procedural geometry, or computational geometry in general. It is assumed that the audience is familiar with basic geometry math
