@nothings@mastodon.gamedev.place My general understanding of the timeline is that compact encodings became popular *after* bitangent reconstruction became standard, so I don't think it was the direct motivation. A matrix inverse though was a tall order at the time, especially because at the time you also had an option to convert light direction into tangent space *in your vertex shader*, as you just had a single light source and fragment compute was precious. Those were the days.
