Trying to achieve free rotation *without* using [accumrotate], I have come across concepts such as multiplying matrixs and converting a matrix to "quarternion" How do you implement precise control of rotation matrixs? Is this exactly what people use GridFlow for?
If you tried GridFlow's bundled examples you'd see what I use GridFlow for. I suppose that I could add some other people's examples in the package, if they sent it to me for that purpose. There is already one patch by Roman Häfeli in GridFlow's examples though.
GridFlow does not support quaternions. I bet it's possible to add support for it using abstractions, but it wouldn't be fast. But I'm willing to add it to the core... there's already a complex-number section in number.c, why not quaternion product? It would be called [# H.*] where H stands for Hamilton (in math the letter Q is already reserved for rationals, so I'd use H even though the concept of rational reasonably couldn't appear in that particular place).
