update to maths utilities

[GordonTombola]

quaternion

• euler method REMOVED
• now has a rotationTo method to get the quaternion to rotation between two vectors (helpful method that was hidden behind gl-matrix)

vector

• lerp would return vec3, casting it to float32array to keep return types consistent

quaternion to euler was extremely unreliable in test cases, seems unfitting to provide it as a utility function when it doesn't give exactly what the user would expect

Thanks! Would it be possible for you to create some tests for quaternion toEuler function?

sure, I'll take a look into it when I get the chance

Just looking into sorting a test out, struggling to understand how to extract an image from the canvas, not entirely sure the best way to do this? I've looked at using the extract plugin on the renderer but that doesn't appear to work for me

• Edit - just figured I could preserve the drawing buffer in my application options in order to use toDataURL on the canvas

[GordonTombola]

After some tinkering, I think its best not to implement as the test cases weren't reliable across more than 2 axis of rotation and beyond 90 degrees +/- in any axis

I see, thanks for giving it a go :)
