The wglShareLists function enables a rendering context to share the display-list space of another rendering context; any number of rendering contexts can share a single display-list space. Starting when glBegin is issued and counting vertices and primitives from 1, the GL gives each flat-shaded line segment i the computed color of vertex i + 1 , its second vertex. . The glCallList subroutine causes the named display list to be executed. There is much controversy over the use of these against Vertex Buffer Objects in relation to speed, so I will show you both, starting with display lists in this tutorial.
