This tutorial will take the application we created in Graphics Setup and teach you how to draw a simple red triangle to the screen. Another option would be to use the same element array for drawing a single line strip, with the alpha of every third vertex set to zero so that the invalid lines (between the last … So we need a way to tell each individual vertex to have it’s own unique position.
