Vec

Find the sum of three vectors in the program (blueChannel, redChannel, alphaChannel), and print the result using gl_FragColor variable.

void main() {

vec4 blueChannel = vec4(0.0, 0.0, 0.75, 0.0);

vec4 redChannel = vec4(0.5, 0.0, 0.0, 0.0);

vec4 alphaChannel = vec4(0.0, 0.0, 0.0, 1.0);

gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0);

}
