This is not Vector it has shading and translucent glass and glare it was made on a primitive 3D engine thinking you could do this with vector is exactly why you don't have UI like this anymore, you cannot.

Hardware acceleration is not a rendering engine it is simply using the video card for assets instead of the cpu, to generate this on the fly you would either have to create your own engine from scratch in the start up, use an open source 3D engine and imbed it into the start up or pay a company to use theirs, none of which are efficient, useful or stable and I remind you this is all for a slider that can be created from a simple api and look ~as good and even if you disagree the vast majority of people do not so their is still no reason to pour more development time into a UI that would be more time consuming, complex and expensive to create than the app itself.
