i have a ceiling fan model which i made myself and rendered it in opengles window now i wnt to rotate the ceiling fan which consists of vertices array which is fixed, so can anyone tell/guide about how to approach this prob.

my code for vertices of fan is something like below :

GLfloat Rotor[] = {

// strip I

-0.545f, 2.6f, 0.20f,
-0.495f, 2.6f, 0.0f,
-0.435f, 2.6f, 0.20f,
-0.485f, 2.6f, 0.0f,

}................... So on..................................

so can anybody tell how to make these coordinates under rotor array rotate ?

and is the problem clear?

Thanks and regards,
Himanshu Sharma
