   OpenGL lines rotation
  glBegin(GL_LINES);  // Draw the line glVertex2f(LEMLine.startX, LEMLine.startY);glVertex2f(LEMLine.endX, LEMLine.endY);glEnd();ok i supply the start and ending XY coords. to draw a line, but the line is translated then rotated. How do i get the new XY starting and ending coord.? If i simply use LEMLine.startX ect., it gives me the original coordinate I supplied it before the translation and rotation.
