The code it becomes

What Studio writes for the graph below: a few lines of the material's shader, worked out for every pixel.

void mainImage(out vec4 fragColor, in vec2 fragCoord){    float n2_out = (pow(max(abs(1.0 - max(dot(vec3(0.0, 0.0, 1.0), vec3(0.0, 0.0, 1.0)), 0.0)), 1e-4), 5.0) * (1.0 - (0.04)) + (0.04));    fragColor = vec4(vec3(n2_out), 1.0);}

Texture coordinates into the node, and the node into the material, as Studio draws them.
