##### Using the ray tracer construct any scene you want, including at least one of all objects. (this can take a while to render, so in the meanwhile you can answer the next questions)
###### Does the image corresponds to the scene you created?
##### Move the camera and render the same scene.
###### Does the image corresponds to the same scene, but from a different perspective?
###### Did the student provided 4 .ppm pictures?
###### Does one of these images consist of a scene with a sphere?
###### Does one of these images consist of a scene with a plane and a cube with lower brightness than in the sphere image?
###### Does one of these images consist of a scene with one of each of all the objects (one cube, one sphere, one cylinder and one plane)?
###### Does one of these images consist of a scene like the previous one, but with the camera in another position (thus generating the same image from a different perspective)?
###### Considering all of the previous pictures, can you see any changes in brightness?
###### Considering all of the previous pictures, can you see shadows from the objects?
