The Open Graphics Library (OpenGL) is the industry standard for high-performance 3D graphics and is widely used to create leading-edge software.As such, what ends up being passed through OpenGL with the constant of GL_LINES is: Since each edge contains 2 vertices, we then say for vertex in edge, do glVertex3fv(vertices), which performs the glVertex3fv OpenGL function on the element of the vertices tuple.Ubuntu 17.10 then upgraded to the Linux 4.15 Git kernel as well as Mesa 17.4-dev via the Padoka PPA for a bleeding-edge look at the Intel open-source.
