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.

WebIf you want slightly less index data, you can use primitive restart indices.This allows you to designate an index to mean "restart the primitive". This allows you to use a GL_TRIANGLE_STRIP primitive and break the primitive up into pieces while still only having a single draw call.

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.
