Hi, is it possible to get the point2 pixelcoordinates on the screen based on a point3 position in the world?

Should be possible since the other way around is.

Nevermind, I found the solution myself. It would be something like this for getting the screencoordinates for a vert:

gw.setTransform(Matrix3 1)
vertpos = polyop.getVert $ 24 node:$ --just a random vert on some object
m = gw.wTranspoint vertpos
screenpos = [m[1],m[2]]
