To avoid the possibility of infinite recursion resulting from display lists calling one another, a limit is placed on the nesting level of display lists during display-list execution. . Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and so on, and use them to construct a sequence of primitives with a single. A quick fix is to delete the displaylist after drawing them, but the current code suggests that there is a more fundamental problem. 8A CN201811355755A CN109583051A CN 109583051 A CN109583051 A CN 109583051A CN 201811355755 A CN201811355755 A CN 201811355755A CN 109583051 A CN109583051 A CN 109583051A Authority CN China Prior art keywords tlm control unit information display list glcalllist Prior art date 2018-11.

I do not know if it was a bug in the drivers. But the objects in the display lists are rendered off their right position. 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). In short, that's because OpenGL libraries under Win32 may produce (under valid circumstances) some.
