“These last move more and more quickly until they reach what is called the vertex of the parabola (the point of such a path which lies nearest to the sun): projectiles, on the contrary, move more and more slowly as they approach the corresponding point of their path; and further, the comet first approaches and then recedes from the centre of attraction -- the projectile first recedes from and then approaches the attracting centre.”
“Another is the ability to separate two components called vertex shaders and fragment shaders that previously had to be linked together.”
“Another is a feature DirectX programmers already enjoy, the ability to separate two components called vertex shaders and fragment shaders that previously had to be linked together.”
“For this parabola, a = -10 so it opens down and the vertex is the maximum point.”
