smathlib

High-Performance C++20 SIMD Mathematics, Non-Euclidean Geometry & Physics Foundation.

Features

• AVX2 / SSE4.1 / ARM NEON Hardware-accelerated Linear Algebra (Vec3, Mat4, Quat).
• High-Performance Python FFI (Process 100k+ vector operations in <1ms).
• XPBD Physics Solver (Extended Position Based Dynamics for cloth & constraints).
• Signed Distance Fields (SDF) & Raycasting.
• Non-Euclidean Geometry (Hyperbolic / Poincaré Ball / Spherical).

Quick Start (Python)

import smathlib as sm
import math

# Vectors
v1 = sm.Vec3(1, 0, 0)
v2 = sm.Vec3(0, 1, 0)
v3 = v1.cross(v2)
print("Cross:", v3)

# Quaternions
q = sm.Quat.from_axis_angle(sm.Vec3(0, 0, 1), math.pi * 0.5)
rotated = q.rotate(v1)
print("Rotated:", rotated)
