Verified usage

Verified import paths — ran on the pinned version, not inferred.

Vector3

✓ from euclid3 import Vector3

✗ from euclid import Vector3

The original euclid package (Python 2) uses 'euclid'; euclid3 uses 'euclid3'.

Matrix4

✓ from euclid3 import Matrix4

Quaternion

✓ from euclid3 import Quaternion

Point2

✓ from euclid3 import Point2

Basic usage showing vector cross product, matrix rotation, and quaternion rotation.

from euclid3 import Vector3, Matrix4, Quaternion v1 = Vector3(1, 2, 3) v2 = Vector3(4, 5, 6) print(v1.cross(v2)) m = Matrix4.new_rotate_axis(1.570796, 'z') rotated = m * v1 print(rotated) q = Quaternion.new_rotate_axis(1.570796, Vector3(0, 0, 1)) print(q)

Debug

Known issues

gotchaVector multiplication uses * for dot product, not @ operator. For cross product, use the .cross() method.

fix

Use v1.cross(v2) for cross product, and v1 * v2 for dot product.

affects: *

deprecatedThe library has not been updated in years (last release 0.01 from ~2016). It may have unpatched bugs and no official support for newer Python versions beyond 3.4.

fix

Consider using alternatives like numpy, pyrr, or pyquaternion for more active development.

affects: 0.01

gotchaMatrix4 multiplication is left-multiplication (matrix * vector). The order matters and may not match other libraries.

fix

Always use matrix * vector for transformation, not vector * matrix.

affects: *

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'euclid'

Attempted to import the old euclid package (Python 2) instead of euclid3.

fix

Install and import euclid3: pip install euclid3, then 'from euclid3 import Vector3'.

AttributeError: module 'euclid3' has no attribute 'Vector3'

Misspelled the class (e.g., vector3 instead of Vector3) or imported the wrong module.

fix

Ensure correct casing: from euclid3 import Vector3

TypeError: unsupported operand type(s) for *: 'Vector3' and 'Vector3' (when trying cross product with *)

euclid3 uses * for dot product, not cross product. For cross product, use .cross() method.

fix

Use v1.cross(v2) instead of v1 * v2 for cross product.
