Rotating an object around a fixed point in opengl

Question

I have a problem with this openGL code:

glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glPushMatrix(); // put current matrix on stack

//glTranslatef(0.0f, 0.         


        

Answer 1

Use this

house();

glTranslatef(x, y, 0.0); // 3. Translate back to original
glRotatef(theta, 0.0, 0.0, 1.0); // 2. Rotate the object around angle
glTranslatef(-m, -n, 0.0); // 1. Move to origin

house();

where m and n are the point on the object around which you want to rotate and x and y are the points around which you want to rotate.
