The alternative is VEX Wrangles. The advantages is that it’s less effort if you’re au fete with VEX and it will more than likely run faster, which doesn’t make any difference on a small scene but if you’re dealing with hundreds to thousands of transforms it soon counts a lot.
The advantages of VOP’s is much like ICE, it’s visual, approachable and artist friendly. VOP’s are threaded too (they generate VEX code behind the scenes automatically) so there’s not much in it for smaller transform challenges. The one gotcha, as you work on larger scenes is that you avoid the old Point SOP as that’s single threaded and even though it’s doing something simple in Oliver’s example, if it’s doing it to 5000 points on a single thread that’s not so good. A lot of artists gravitate towards Wrangles in the long run and save VOP’s for things like procedural noise (which is trickier to manage in Wrangles). VEX snippets in Wrangles is pretty approachable too. The documentation is good and folk like Entagma and Matt Estella (Tokeru Wiki) includes bite sized chucks of VEX in their tutorials – which eases the path considerably as you’re always learning through context.
