As a result, the commands saved in each display list are executed in order, just as if they were called without using a display list. But It takes a lot of time to built display list and re-build it if scene is modified. 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). This is a simplification of some math software that I've been working on writing, and it seemed like it was going well up until this point.

Execute the list using glCallList(ID); Note how we use a display list to draw a picket of the fence. void EndList ( void );1. The following function retrieves information related to. JOGL depends on some run-time support classes and native code provided by the GlueGen project; these. The idea is that we create pipe_resource for each glBitmap call when a display list is being recorded, and glCallList just draws a textured quad through our glBitmap path. The memory leak happens because a new displaylist gets created ( glNewList) everytime drawObject is called, but they never get deleted. The glGenTextures command is not recorded into the display list, it is executed immediatelly. 1 Answer. 当显示列表准备好（被编译完成. init () display = (1700, 1000) pygame.
