Hi,
thanks a lot for filling this gap in golang!
Lets get to it: I think there is a problem in mat4.Quaternion()
A. for calculating the trace only the part of the rotation matrix should be taken (…

There is no quaternion module in this common directory, how can I fix it?

For this code:
```dart
import 'package:vector_math/vector_math.dart' as VM;
void TestMe(VM.Quaternion dir) {
print("quad: ${dir}");
VM.Matrix3 rot = VM.Matrix3.identity();
VM.Vector3 x…

Unless I'm mistaken, there's no way to use this for quaternions.

I tried to make a quaternion, and any method other than direct field assignment after definition caused either an assertion failure or a panic. I saw the first error and thought that was fine, but bot…

Hi
I noticed that the axis of the unit quaternion (1,0,0,0) is returned as (0,0,0).
This code
from pyquaternion import Quaternion
q=Quaternion()`
print("q: %s"%q)`
prin…

We already have `glm_quat_rotatev()` ( which is similar to `simd_act()` I guess ), `glm_quat_rotate()` , `glm_quat_rota…

`q*q` and maybe some other functions use the less popular Shuster's convention, which may be confusing to some. (Maybe add traditional variants?) (`qmat` uses the formula that is used with traditional…

**Is your feature request related to a problem? Please describe.**
Feature: I would need to deal with quaternion algebra from cupy rather than from numpy.
**Describe the solution you'd like**

Currently SimMath provides `Quatd.toRotationMatrix()` to convert a `Quatd` to an equivalent rotation matrix.
It would be useful to provide the inverse as well: a method that converts a `Matrix3d` to …
