Parameters mode Specifies what kind of primitives to render.
Description glDrawArraysEXT makes it possible to specify multiple geometric primitives with very few subroutine calls. When glDrawArraysEXT is called, count sequential elements from each enabled array are used to construct a sequence of geometric primitives, beginning with element first . Vertex attributes that are modified by glDrawArraysEXT have an unspecified value after glDrawArraysEXT returns. Attributes that aren't modified remain well defined. Operation of glDrawArraysEXT is atomic with respect to error generation.
