This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.


The dvector library provides both common and more specialized 2D/3D vector math operations, its features include:

  • No hard dependencies besides the standard library, making it fully portable for most purposes
  • Provides vec2, vec3, vec4, quat, mat2, mat3, and mat4 types with various important operations
  • Supports an additional frst type along with frustum culling functions for spheres and AABBs
  • All dvector types are pass-by-value, allowing for easy use as arguments or return values
