### Note - Skip Motion Blur and Perlin Noise

We are skipping Chapter 2 Motion Blur and Chapter 5 Perlin Noise as they are not essential to the project.

As we are not using Motion Blur, take care of the sphere constructor code: not use **static\_center but stick to center in Task 1**.

As we are not using Perlin Noise, use our earthmap texture instead of the Perlin noise texture in Task 5.

They are marked in my source code in T1 and T5.
