2D Drawing

Recommended Posts

I'm doing some 2D drawing with glDrawArrays. Is there a simple way to translate all the points by some x and y position or do I have to manually translate all the points I send to glVertexPointer?

Typically you would use the 'modelview' matrix for this, e.g.:
glMatrixMode(GL_MODELVIEW);
glPushMatrix();
glLoadIdentity();
glTranslatef(x, y, 0.f);
Render();
glPopMatrix();
If that doesn't answer your question, you may need to provide some more details about what it is exactly that you're trying to do.
