However I’m still just a little confused, because the way I do it is by calling the function glfwLoadTexture2D every loop to apply it, but I’m thinking that that’s not very efficient to load the texture every loop. As per the documentation, glGenLists returns the first list name in a range of the length you pass to glGenLists. Thus, for example, GL type int is referred to as GLint outside this document, and is not. 8-gles 7. - opengl. When using display lists, the driver can store the object as efficiently as.
