What’s the difference between glDrawArrays and glDrawElements ?

Can anyone help me?

Thanx,

glDrawArrays submits the vertices in linear order, as they are stored in the vertex arrays.
With glDrawElements you have to supply an index buffer. Indices allow you to submit the vertices in any order, and to reuse vertices that are shared between triangles.
