Computer Vector Graphics Math Library

Because reinventing the wheel is half the fun.

A path tracing scene using cvmath. See pathtracing.rs.

🔍 What is this?

cvmath is a lightweight, graphics-oriented math library written in Rust. It focuses on vector math and geometric primitives commonly used in computer graphics. It is not a general-purpose numerical library.

If you're building 2D/3D renderers, ray tracers, or similar tools and want something compact and to the point, this might be a good fit.

The API is lean, clear, and practical.

✨ Features Overview

All types are available at the crate root.

General Types

• Vec2<T>, Vec3<T>, Vec4<T> — 2D, 3D, and 4D vectors
• Bool2, Bool3, Bool4 — Boolean vector masks
• Angle<T> — Angles in radians
• Complex<T>, Polar<T>, Quat<T> — Complex numbers, polar coordinates, and quaternions

Matrices and Transformations

• Mat2<T>, Mat3<T>, Mat4<T> — General-purpose matrices
• Transform2<T>, Transform3<T> — Affine transformations

Shapes and Geometry

Shapes are available in 2D and 3D variants.

• Point2<T>, Point3<T> — 2D and 3D points
• Bounds2<T>, Bounds3<T> — Axis-aligned bounding boxes
• Plane2<T>, Plane3<T> — Infinite planes
• Circle<T>, Sphere<T> — Defined by a center point and radius
• Line2<T>, Line3<T> — Line segments defined by two points
• Triangle2<T>, Triangle3<T> — Triangles defined by three points
• Shape2<T>, Shape3<T> — Generic shape enums for flexible composition

Ray Tracing

Types involved in ray casting and intersection:

• Ray2<T>, Ray3<T> — Rays defined by origin, direction, and max distance
• Hit2<T>, Hit3<T> — Intersection results (distance, normal, index)
• Trace2<T>, Trace3<T> — Traits for types that support ray tracing
