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. Web19 de ago. de 2024 · A primitive type can have multiple leading vertices defined, as long as each one is used for a different primitive. For a triangle strip with adjacency, the leading vertices are 0, 2, 4, 6, and so on. For a line strip with adjacency, the leading vertices are 1, 2, 3, and so on. An adjacent primitive, on the other hand, has no leading vertex. how did they clean up the molasses flood

"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.
