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.
