[fpc-pascal] Calculating Pixels to represent 3D coordinates

I'm curious if Freepascal has any package available that would calculate X,Y screen pixels based on 3D  X,Y,Z  data at some given rotations.  I'm using Agg-Pas with PTC-Graph in a console application on Windows.   I'm not sure what the technical term is for figuring out what pixels are used to represent 3D coordinates on a 2D screen, but I'm hoping maybe there is something that just does the calculations that I can use in conjunction with Agg-Pas and PTC-Graph instead of moving to a complete graphics package.
