GRAPH 3D v2.425 (20-FEB-2017)

[Han]

For those who find the slower rendering a bit too slow for your liking, you can make a minor modification to the code in order to change the rotation to a "box-only" rotation in the same sense as moving a program window in Windows and seeing only the rectangular border move until the window is "placed" somewhere new on the desktop and the contents of the window are finally rendered.

In the function g3D_keys() change the code

Code:


        if key==3 then rotx:=(rotx-5) MOD 360; end;
        if key==45 then zoom3D:=max(zoom3D/1.05,.01); end;
        if key==50 then zoom3D:=zoom3D*1.05; end;
      end;
      g3D_rotmatrix();
      g3D_draw(); // <------------- change this line
    until NOT iskeydown(key);
                   // <------------- and change this line
    end;

to

Code:


        if key==3 then rotx:=(rotx-5) MOD 360; end;
        if key==45 then zoom3D:=max(zoom3D/1.05,.01); end;
        if key==50 then zoom3D:=zoom3D*1.05; end;
      end;
      g3D_rotmatrix();
      rect(G1); g3D_drawbox(); blit_p(G0,G1); // <---------- to this
    until NOT iskeydown(key);
    g3D_draw(); // <-------- and to this
    end;
