Is DxScene the "WPF for Delphi"? Anyone used it?

Yes, I am using it now in a new project and intend to use it for all future projects.

It's indeed extremely powerful and versatile. It does consume SVG and even XAML, among many other formats, so you could consider it as a Win32 API WPF alternative. Believe me, I've been looking for one for ages, and this is it for me.

Current drawback: lack of documentation. You have to learn it all from the examples and by asking questions in their forum. Not ideal, but it can only get better!

All it needs is more users, and it'll grow into something wonderful.
