Screen XY location for point in cartesian coordinates

I’ve been looking around for a means to get the Screen XY coordinates from a point in 3d space. I’ve been looking at the various frustrum-related methods for the ActiveViewport, which lets me quite easily go from the screen to the world, but am having trouble figuring out how to invert the process…thanks in advance!

If you have the screen to world Transform, you should be able to get the inverse of the Transform. This does the world to screen mapping.
