Convert Delphi code to C++ Builder code

I have a sample project written in Delphi I need converted to C++Builder. The Delphi project is named ThreeDLab and shows how to draw and rotate a Cube, Globe and Mesh. It is written for the 32bit VCL Windows platform and uses the GDI Canvas. I have started a C++Builder project to convert all the Delphi code but my knowledge of Delphi is not good enough to finish. The attachments are the original Delphi project in a zip file named Delphi_ThreeDLab.ZIP. My C++Builder project is in a .zip file named CPP_3DLabProject.zip. I am using C++Builder XE4 Pro VCL 32bit platform. You should be able to use any version of Delphi and C++Builder and get these projects working. The attached picture shows the output of my C++Builder project and the Delphi project for the 3D Mesh. You can see my version does not work. What I need: 1) The final C++ project should not use the .PAS files or Delphi code. 2) The Delphi code uses a custom class named TPantoGraph which links a canvas with the calculations and draw functions. I need the C++ code to NOT use this custom class. I will eventually be using a different canvas system so I need the canvas and calculations separate. 3) The C++ Builder version should draw the Cube, Globe and 3D Mesh correctly. 4) Each of the five settings (1)Azimuth (2)Elevation (3)Distance (4)Width / Height and (5)To Camera, should correctly move the object being drawn. end.
