Unity.mathx — extension library for Unity.Mathematics

Fluent, shader-like extensions for Unity.Mathematics — noise, SDFs, fast math, and Burst job helpers in one using static.

Get started API reference GitHub
com.ltmx.mathematics.mathx

Quick start

using static Unity.Mathematics.mathx;

float3 v = new float3(1, 2, 3);
return v.length().clamp(0, 10).normalize();

Every method lives on the single mathx partial class — one import and you're done.

Fluent chains

return anyVector
    .length().clamp(0, 10).cos().sq()
    .rotate(anyQuaternion).div(3.2f).rcp().mul(3.2f).sum();

anyVector = math.clamp(math.length(anyVector), 0, 10);
anyVector = math.cos(anyVector);
anyVector = anyVector * anyVector;
anyVector = math.mul(math.rotate(anyQuaternion, anyVector), 1f / 3.2f);

See the Fluent chains guide for .set(out x) and when to break a chain.
