geomcore (Python bindings)

Python bindings for geomcore, a pure, standalone geometric kernel for CAD-grade curves and surfaces — parametric evaluation, rigid transformations, and analytic curve-on-surface parametrization, implemented in Rust.

from geomcore import Point3D, Vector3D
from geomcore.curves import Circle3D
import math

circle = Circle3D(Point3D.origin(), Vector3D.z(), 2.0)
point = circle.eval_point(math.pi / 4)

Install

pip install geomcore

Pre-built wheels are published for Linux (x86_64, aarch64), macOS, and Windows, for Python 3.9+ (abi3 — one wheel covers all versions).

What's inside

  • Parametric evaluation for lines, circles, ellipses, parabolas, hyperbolas, and B-spline curves (rational and periodic), plus planes, cylinders, cones, spheres, tori, and B-spline surfaces.
  • Bulk evaluation (eval_points) with a single native call per batch.
  • Rigid transformations via a single Transform type.
  • Analytic curve-on-surface parametrization (parametrize_on) for lines and circles on the five elementary surfaces.

All numeric results are validated against golden fixtures at CAD-kernel-grade tolerances (1e-7). See the repository for full documentation, the roadmap, and the Rust crate.
