What's New


Release Date: July 18, 2020

Typescript Type Definitions

Typescript type definitions (.d.ts files) are now provided for all modules.

A new module offering geospatial polygon clipping functions.


Date: Dec 16, 2019

  • viewport-mercator-project has been added to a new sub-module.


Date: Aug 8, 2019

The 3.0 release brings support for geospatial math, culling, performance improvements, and some API consolidation.

A new module (developed in collaboration with the Cesium engineering team) providing WebGL-framework-independent geospatial math classes and algorithms:

  • New class Ellipsoid and constant Ellipsoid.WGS84 for working with WSG84 coordinates

A new module (developed in collaboration with the Cesium engineering team) providing WebGL-framework-independent classesthat support geometric intersection calculations (primarily intended to support frustum culling operations):

  • New class AxisAlignedBoundingBox
  • New class OrientedBoundingBox
  • New class BoundingSphere
  • New class CullingVolume

Transform API Consolidation

The API for transformations (i.e. multiplying vectors with matrices or quaternions) has been extended and made more orthogonal:

  • The transform* methods are now available on all Vector classes, in addition to on the Matrix classes. Among other things, this enables transformations without using Matrix classes.
  • Naming consistency of transform methods across classes (transform, transformAsPoint, transformAsVector).
  • Alternative transform methods added to the Vector classes (transformByMatrix3, transformByMatrix2, transformByMatrix2x3 and transformByQuaternion). Simplifies using the most efficient transformation for the job.

Matrix classes

  • New methods Matrix*.setColumn() and Matrix*.getColumn()
  • New method Matrix*.toString()
  • Improved method: Matrix4.frustum() now supports infinite far plane (parity with Matrix4.perspective, which already supported this).

Utility Functions

  • New: global functions toRadians and toDegrees
  • New: global function exactEqual

Performance Improvements (and Website Benchmarks)

A benchmarking example has been added to the website that makes it easy to assess the performance of the library on your own browser. The library has been carefully tuned based on these benchmarks and performance of the library has been significantly improved over version 2.x.


Date: Jan 29, 2019

  • New class: Matrix3
  • New: Add scale factor support to Matrix3 and Matrix4
  • Support quaternion to euler conversion
  • Now uses the official gl-matrix@3.0.0 package as dependency instead of forked gl-matrix packages.


Date: Sep 20, 2018

  • Use @babel/runtime to reduce bundle size
  • equals function fix on arrays


Date: June 25, 2018

New Naming Convention for Experimental Exports

Experimental exports are now exported with a leading underscore (_), instead of as members of the experimental namespace.

The change was made to make it possible for tree-shaking bundlers to remove unused experimental exports from applications.


Date: May 4, 2018

  • New lerp utility
  • Experimental Pose class


Date: April 16, 2018

Matrix4 Improvements

Matrix4.orthographic() - To simplify switching between perspective and orthographic views, now offers an additional method for creating orthographic projection matrix, that takes the same parameters as Matrix4.perspective(), with the addition of one additional parameter, focalDistance. See Matrix4.orthographic({fovy, aspect, focalDistance, near, far})

Bundle Size Reduction has been tuned to have approximately 20% smaller footprint when bundled in applications.

THREE.js Compatibility classes now pass large parts of the THREE.js test suite, which should make it easier to reuse code written for the THREE.js math library.
