    Methods in com.io7m.jtensors that return QuaternionI4F
    Modifier and Type | Method and Description
    --- | ---
    `static QuaternionI4F` | QuaternionI4F.`add(QuaternionReadable4FType q0, QuaternionReadable4FType q1)` Calculate the element-wise sum of the quaternions `q0` and `q1`.
    `static QuaternionI4F` | QuaternionI4F.`conjugate(QuaternionReadable4FType q)` Calculate the conjugate of the input quaternion `q`.
    `static QuaternionI4F` | QuaternionI4F.`interpolateLinear(QuaternionReadable4FType q0, QuaternionReadable4FType q1, float alpha)` Linearly interpolate between `q0` and `q1` by the amount `alpha`, such that: `interpolateLinear(q0, q1, 0.0) = q0` `interpolateLinear(q0, q1, 1.0) = q1`
    `static QuaternionI4F` | QuaternionI4F.`lookAtWithContext(QuaternionI4F.ContextQI4F context, VectorReadable3FType origin, VectorReadable3FType target, VectorReadable3FType up)` Produce a quaternion that represents a rotation that "looks at" the point at `target` assuming the viewer is at `origin`, using `up` as the "up" vector.
    `static QuaternionI4F` | QuaternionI4F.`makeFromAxisAngle(VectorReadable3FType axis, double angle)` Produce a quaternion that represents a rotation of `angle` degrees around the axis specified by `axis`.
    `static QuaternionI4F` | QuaternionI4F.`makeFromRotationMatrix3x3(MatrixReadable3x3FType m)` Produce a quaternion equivalent to the rotation matrix `m`.
    `static QuaternionI4F` | QuaternionI4F.`makeFromRotationMatrix4x4(MatrixReadable4x4FType m)` Produce a quaternion equivalent to the rotation matrix `m`, writing the result to `out`.
    `static QuaternionI4F` | QuaternionI4F.`multiply(QuaternionReadable4FType q0, QuaternionReadable4FType q1)` Multiply the quaternion `q0` by the quaternion `q1` .
    `static QuaternionI4F` | QuaternionI4F.`negate(QuaternionReadable4FType q)` Negate the elements of `q`.
    `static QuaternionI4F` | QuaternionI4F.`normalize(QuaternionReadable4FType q)` Normalize the quaternion `q`, preserqing its direction but reducing it to unit length.
    `static QuaternionI4F` | QuaternionI4F.`scale(QuaternionReadable4FType q, float r)` Scale the quaternion `q` by the scalar `r`.
    `static QuaternionI4F` | QuaternionI4F.`subtract(QuaternionReadable4FType q0, QuaternionReadable4FType q1)` Subtract the quaternion `q0` from the quaternion `q1`.
