Display lists were removed, because with opengl 3+ all vertex, texture and lighting data are stored on the graphics card, in what is called retained mode rendering (the data is retained, allowing you to send a single command to the card to draw a mesh, rather than sending vertex data to the card every frame). For instance assume current matrix is C, translation matrix is T, Rotation matrix is R, identity matrix is I. If you have a hardware OpenGL implementation, then glCallLists might be able to just transfer a few tens of bytes to the hardware in one shot, versus the back-and-forth of many seperate glCallList. Names that reference valid display lists are executed; others are ignored. The memory leak happens because a new displaylist gets created ( glNewList) everytime drawObject is called, but they never get deleted. java. glCallList can appear inside a display list. inside the display () method, calling renderTriangle (gl, 100); directly works as expected, a triangle 200 pixels wide appears on the screen. glWindowPos2 specifies the x x and y y coordinates, while z z is implicitly set to 0.
