Examples of toAxisAngle()

toxi.geom.Quaternion.toAxisAngle()
Converts the quaternion into a float array consisting of: rotation angle in radians, rotation axis x,y,z @return 4-element float array

Examples of toxi.geom.Quaternion.toAxisAngle()

    public void testCreateFromAxisAngle() {
        ReadonlyVec3D axis = new Vec3D(100, 100, 100);
        float angle = MathUtils.PI * 1.5f;
        Quaternion a = Quaternion.createFromAxisAngle(axis, angle);
        assertEquals(MathUtils.sin(-MathUtils.QUARTER_PI), a.w);
        float[] reverse = a.toAxisAngle();
        Vec3D revAxis = new Vec3D(reverse[1], reverse[2], reverse[3]);
        assertTrue(axis.getNormalized().equalsWithTolerance(revAxis, 0.01f));
        assertTrue(MathUtils.abs(angle - reverse[0]) < 0.01);
