Hello,I've got a question.
For example,I have two 2 triangles and I want to rotate only first. How do I use glTranslate/glRotate?Do I have to use them in display function or somewhere else?

void display()
{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glRotatef(angle, 1.0, 0.0, 0.0);
glTranslatef(0.0f,0.0f,0.0f);
drawFirstTriangle();

glPopMatrix();


glPushMatrix();

drawSecondTriangle();

glPopMatrix();

glutSwapBuffers();

}


Hope this will help.
