Detailed Description

Wraps the OpenGL function glDrawArrays().

See also http://www.opengl.org/sdk/docs/man/xhtml/glDrawArrays.xml for more information.

DrawElements, MultiDrawElements, DrawRangeElements, DrawArrays are used by Geometry to define a set of primitives to be rendered, see Geometry::drawCalls().
