# Thread: drawing cone and cylinder

1. ## drawing cone and cylinder

hi to all of u..

i m doing my final project now, and i really REALLY want to know how to draw cone and cylinder using openGL..i hope all of u here can help me...

thanks

So do you want to know how to get opengl to work or just the algorithm for cone and cylinder?

gav

yup...i want to know how get opengl to work on those cones and cylinders..

4. ## Re: drawing cone and cylinder

gluCylinder will do the job for you.

Code :
```GLUquadricObj *quadObj = gluNewQuadric();
gluCylinder(quadObj, base, top, height, slices, stacks);```
i think.

Uhmm... thought you could figure that out

A cone is a cylinder with top (or bottom if you want the cone "up side down") radius set to zero.

I would like to draw a so-called-cylinder but the base and top are not parallel. Any ideas if there is such a function or do I need to hardcode it. If so, how?

A gluCylinder most certain is! Are you sure you have not just rotated the model with a viewing transform or something?

9. Wrote an article describing how to draw a cone without using GLU/GLUT, would be happy to know if there are errors!
