In one case it was transposed and in another was missing / w coefficient.

Thanks, I guess I wasn't actually using this code so it slipped by; out of curiosity what are you using it for?

I was originally using glm for vector and matrix math, but removed it since I didn't want it in the API. On second thought maybe I should have kept it and just used it internally, wrapped by the tlRender classes.

For rotating the images and for perspective transformations on sphere mapping and environment cube mapping.
