Weblayout (triangles) in; layout (triangle_strip, max_vertices=3) out; layout (lines) in; layout (line_strip, max_vertices=2) out; The shader will compile and run, but will only render lines (or whatever the last primitive defined is). So how do I define a single geometry shader that will handle multiple types of primitives? something bout a truck line dance

WebAs OpenGL Objects, VAOs have the usual creation, destruction, and binding functions: glGenVertexArrays, glDeleteVertexArrays, and glBindVertexArray. The latter is different, in that there is no "target" parameter; there is only one target for VAOs, and glBindVertexArray binds to that target. Note: VAOs cannot be shared between OpenGL contexts.
