My teacher have given me an assignment to build a 3D car in C language using Turbo C compiler only....
I'm very confused how to start making it....
kindly help me!!!!
how to start?
please help me

I am allowed to use only basic functions of C (like line(), polygon(), putpixel(), floodfill())

I thinjk we would need more specific information to help you. Are you using a linear algebra package? What about for graphics - OpenGL?

Hey I've given all information needed..
kindly help me now!!!!

I'm afraid I am mainly knowledgeable in C++, but what I would do is take some graph paper and plot out the points on a car.

For example, to make a box, I'd have points at:

(0,0,0)
(1,0,0)
(0,1,0)
(1,1,0)
(0,0,1)
(1,0,1)
(0,1,1)
(1,1,1)

Once you have your car-on-paper, you can begin translating it into code.

I would draw a polygon between each of those points. This totals to six polygons. Also, make sure the normals are facing outwards. So, if you're doing the bottom of the box - do (0,0,0) then (0,1,0) then (1, 1, 0) then (1, 0, 0). Notice, this traverses the points in a clockwise manner - so the normal points downwards. The "outside" part of the plane that forms the box bottom faces down.

Repeat this process for all items.
