geometrix 0.1.16

LaTeX-first differential geometry renderer for Jupyter/Colab.

Geometrix

LLM-assisted LaTeX-first differential geometry renderer for Jupyter/Colab. Ask for symbolic solutions (with full derivations), then graph them immediately.

Flagship: LLM → Graph

From examples/14_llm_assist2.py.

LaTeX-first differential geometry renderer for Jupyter/Colab. Write math in LaTeX, sample it numerically, and render with an interactive Three.js viewer.

Install

pip install geometrix

Quickstart (Notebook)

from geometrix import geom

scene = geom("""
coords: u v
X(u,v) = (u, v, 0)
render: surface X domain u:[0,1] v:[0,1] res 30 30
""")
scene.show()

LaTeX-First Workflow

import sympy as sp
from geometrix import latex, show
from geometrix.api import SceneBundle
from geometrix.sample.domains import Domain
from geometrix.sample.surface import sample_surface_grid
from geometrix.scene.build import build_surface_scene
from geometrix.symbolic.compile import compile_vector

u, v = sp.symbols("u v")
x = latex("u", show_latex_expr=True)
y = latex("v", show_latex_expr=True)
z = latex("\\sin(u)\\cos(v)", show_latex_expr=True)

compiled = compile_vector([x, y, z], [u, v])
surface = sample_surface_grid(
    compiled,
    [Domain("u", -sp.pi.evalf(), sp.pi.evalf()), Domain("v", -sp.pi.evalf(), sp.pi.evalf())],
    [60, 60],
)
scene = build_surface_scene(surface.positions, surface.grid_shape)
show(SceneBundle(scene=scene, arrays={"positions": surface.positions}))

Viewer Controls

• Toggle axes, grid, gizmo, legend, and light mode.
• Drag gizmo arrow tips to move the locator; coordinates update in the panel.
• Grid planes and tick labels adapt to the data range.

Input Types

• LaTeX expressions via latex() (math-first workflow).
• DSL blocks via geom(...) for quick parametric surfaces.
• Python arrays for points/lines/meshes (via points(), line(), mesh()).

Symbolic Utilities

import sympy as sp
from geometrix import canonicalize, simplify, solve

x = sp.symbols("x")
expr = (x**2 - 1) / (x - 1)
print(canonicalize(expr))
print(simplify(expr, mode="factor"))
print(solve([x**2 - 1], [x], dict=True))

Coordinate Helpers

import numpy as np
from geometrix import cylindrical_to_cartesian, spherical_to_cartesian, lorentz_metric

r, theta, z = np.array([1.0]), np.array([0.5]), np.array([0.0])
xyz = cylindrical_to_cartesian(r, theta, z)
metric = lorentz_metric()

Notes

• LaTeX parsing uses a safe allowlist of commands; unknown commands are rejected.
• Indices use the symbols i, j, k, l, m, n, a, b, c, d by default.
• The HTML renderer loads Three.js from a CDN (no widget install needed).
