To Draw and visualize 3D projection Fron view top view and side view using c program 3 Dimensional Projection in C program CS1355-Graphics & Multimedia Lab projections of 3D images.
Algorithm
Start the program 3D projection Images
Using for loop get the no of corrdiante of the 3D view
Using line funtion in graphics we draw the projection
Front view is draw by the following code
if(i!=fs-1)
line(x[i]+some constang value,y[i],x[i+1]+some constant value,y[i+1]);
else
line(x[i]+some constant value,y[i],x[0]+some constant value,y[0]);
in For loop
like that the other top view and side view is drawn by the line function
Finally terminate the 3 Dimensional image view in Front view,Top view and side view

getch();//side view
for(i=0;i
line(10,y[i],10,y[i+1]);
line(10+d*2,y[i],10+d*2,y[i+1]);
line(10,y[i],10+d*2,y[i]);
line(10,y[i+1],10+d*2,y[i+1]);
}
getch();
closegraph();
}
Output three dimensional proection front view top view side view in c program
