Vertex Array and Multitexturing

[enmaniac]

Is it possible to perform multitexuring ( one texture on the other ) using vertex arrays ?? I mean when you use VA you enable proper client states, setup pointers and finaly drawing using ie glDrawArrays. But how to enable multitexturing ??

Thx in advance

I think you can send one texture coord pointer per texture unit.

What does it mean 'texture unit'?? Does it mean that multitexturing can be done only inside glBegin/glEnd specifying glMultiTexCoord2fARB for every vertex ?? Isn't there any faster method to do it?? glBegin/glEnd with glVertex'es is extremally slow method for displaying thousands of faces isn't it ??

You need glClientActiveTextureARB to select the coordinate set influenced by glTexCoordPointer and glEnableClientState.
