tur-math

2D/3D vector and matrix math for Turmeric: vec2, vec3, vec4, mat4, quaternions, and common scalar helpers.

Overview

tur-math is a Tier 1 spice (pure Turmeric, no C deps). It exposes the linear-algebra primitives you typically need for graphics, physics, and geometry: vectors with arithmetic and normalization, 4x4 transform matrices, and unit quaternions with slerp.

The implementation is deliberately small and allocation-light so it can be used alongside tur-opengl, tur-raylib, and the GLSL DSL without surprises.
