Built-in functions | Vector Normaliztion

Vector Normaliztion

Write a shader program that divides the screen into two equal parts. The origin of the left part is at (0.25, 0.5), and the origin of the right part is at (0.75, 0.5). In the left part, display the cosine of the angle between the positive X-axis and the vector directed from the origin to the current pixel position. In the right part, display the sine of the angle between the positive X-axis and the vector directed from the origin to the current pixel position.
