Documentation / @imvu/cal3d / Quaternion

Class: Quaternion

Defined in: packages/cal3d/src/math.ts:45

A rotation quaternion, exactly as stored in the file.

IMVU's runtime negates w on load and negates it back on save (an in-memory convention of its fork). This library keeps the file's values untouched, which is also what upstream Cal3D does.
