We’re planning to improve Make Icosphere performance before the final Vuo 1.2.0 release.
When the Make 3D Object nodes receive an event, most of them regenerate their geometry and re-upload it to the GPU. So another way to improve performance is to just execute the Make node once, then apply a transformation using another downstream node such as Combine 3D Objects, like this:
In the final Vuo 1.2.0 release, we improved the performance of Make Icosphere. (Though in general, as with any 3D mesh generator, I’d still recommend using its built-in Transform port just for static positioning, and instead using Combine 3D Objects for animation.)
