Web27 de jun. de 2012 · The spec’s language with regard to primitive restarting makes no exceptions for primitive types, geometry shaders, or anything at all. If the above two commands are defined behavior, then according to the spec, it should work. Therefore, if it doesn’t, (and everything else is correct), it is a driver bug. WebOpenGL lines Three different line primitives can be created: GL_LINES draws a line segment for each pair of vertices. GL_LINE_STRIP draws a connected group of line segments from vertex v0 to vn connecting a line between each vertex and the next in the order given. GL_LINE_LOOP similar to GL_LINE_STRIP, except it closes the line from
