Compose a scene (MUST USE GLSL) that includes ray tracing to spheres & implement the specular component of Phong reflection based on the following(starter)

• ray trace to two or more spheres, perhaps create an interesting character.
• create other sorts of natural materials using the noise-based procedural texture.
• can add multiple light sources.
• can add a sky gradient.

uniform float uTime; // TIME, IN SECONDS // RAY TRACE TO ALL OBJECTS IN THE SCENE varying vec3 Pos; // -1 0. ) { float t = -B - sqrt(D); void main() { // IF RAY HITS SPHERE // WHERE, FOR YOUR HOMEWORK, YOU CAN WRITE ANY W/ CODE YOU LIKDEFINE A COLOR FOR THIS FRAGMENT. if (t > 0. && t 0. ) { float t = -B - sqrt(D); void main() { // IF RAY HITS SPHERE // WHERE, FOR YOUR HOMEWORK, YOU CAN WRITE ANY W/ CODE YOU LIKDEFINE A COLOR FOR THIS FRAGMENT. if (t > 0. && t
