DECLARATION

in int gl_VertexID ;.SH "DESCRIPTION"

gl_VertexID is a vertex language input variable that holds an integer index for the vertex. The index is implicitly generated by glDrawArrays and other commands that do not reference the content of the GL_ELEMENT_ARRAY_BUFFER, or explicitly generated from the content of the GL_ELEMENT_ARRAY_BUFFER by commands such as glDrawElements. For glDrawElements forms that take a basevertex, gl_VertexID will have this value added to the index from the buffer.
