jtensors

The jtensors package package implements a set of vector and matrix types, intended for use in computer graphics software.

Features

• 2D, 3D, and 4D immutable vector types in float and double versions.
• 2D, 3D, and 4D immutable vector types in int and long versions.
• 4D immutable quaternion types in float and double versions.
• 2x2, 3x3, and 4x4 mutable matrix types in float and double versions.
• Phantom-typed variants of all types for statically distinguishing between semantically different but otherwise type-compatible vectors and matrices.
• Fully documented (Javadoc).
• Massive battery of tests for checking the behaviour of matrix/vector implementations.
• 100% automated unit test coverage.
• OSGi-ready
• JPMS-ready
• ISC license.

Development Snapshots

At the time of writing, the current unstable development version of the package is 11.0.1-SNAPSHOT.

Development snapshots may be available in the Central Portal Snapshots repository. Snapshots are published to this repository every time the project is built by the project's continuous integration system, but snapshots do expire after around ninety days and so may or may not be available depending on when a build of the package was last triggered.
