gl-matrix 3.4.0, but with strict types to help the browser optimiser. You are expected to use gl-matrix alongside this, for cases where you don't know the type of the inputs/outputs, to avoid deoptimising functions in this library.

There are also other changes to the library, such as:

• No chaining (no return values in most functions)
• Some utils are missing
• If matrix inversion fails, you're on your own. There is no return value, and you will get a bad result
• No str functions
• No mat2, mat2d, mat3d or vec2
• Renamed functions are not re-exported. For example:
  • quat.length doesn't exist, use vec4.length
  • quat2.getReal/quat2.setReal -> quat.copy
  • *.mul -> *.multiply
• No forEach functions
• No custom types. Use typed arrays instead
• random has no scale factor anymore. Call scale afterwards instead
• Far planes can't be null; must either be a finite number or Infinity, not null
• perspectiveFromFieldOfView doesn't use an object for passing degrees
• Random function is not configurable
• round function no longer exists, and the browser's round implementation is used instead
• Default angle order is no longer configurable
• Angle order is now passed as a numeric enum
• Epsilon is no longer configurable
