A very quick update on my holiday “fun”. After a bit of work I managed to combine two VASA voxel models - one for the visibility cone and one for its intersection with Forma’s site surroundings, something we saw last time - into a single Forma mesh.
You can hopefully see that the performance is very decent, and the translucent, fog-like effect of the cone to be a reasonable visual complement to the intersection area.
I ended up going through the extra effort to combine them both into a single mesh - putting the vertices together as well as their respective colours - to keep the performance snappy: I'd tried pumping the two meshes through Forma's rendering API separately, to start with, which led to a modest lag as the two meshes were drawn in sequence.
Here's another example of the extension visualizing visibility in a model of Las Vegas.
