Doom to Delphi Total Conversion (DelphiDoom)

One of the new features of DelphiDoom's software renderer is the a pseudo-3D perspective view. It's a combination of z-axis shift and a is a post-processing step where we shrink horizontal rows of the rendered scene. This feature is available in both 8 bit and 32 bit color modes. We can turn it on and off using the usefake3d console command.
To enable open console and type:
usefake3d on
To disable it type:
usefake3d off
You can also access this feature from the menu. Go to Options/Display Options/Advanced/True 3D emulation.
