JAVA: GUI Implementation of the remote Intersection Algorithm

JAVA: GUI Implementation of the remote Intersection Algorithm

Compiling environment:

Operating System: Win8.1 64-bit

IDE platform: Visual Studio 2013 Ultimate

I. Principles

Observe the distance S1, S2, and S3 on the P to be tested, and then determine the plane coordinates of P:
