Final answer:
The primary difference in skills between 2-D and 3-D animation is that 2-D animation requires great drawing skills, while 3-D animation requires proficiency in CGI and 3-D software. Drawing skills can be helpful in 3-D for conceptual work but are not central to the animation process as they are in 2-D.
Step-by-step explanation:
The skills required for 2-D and 3-D animation are distinct. For 2-D animation, great drawing skills are often essential because artists need to create frame-by-frame illustrations that represent motion. This type of animation relies heavily on the animator's ability to draw consistently and with a sense of fluid motion.
In contrast, 3-D animation primarily involves working with digital models in a three-dimensional space. While drawing skills can be beneficial for concept art and storyboarding in 3-D animation, they are not as central as skills in CGI (Computer Generated Imagery).
Mastery of 3-D software and understanding of modeling, rigging, texturing, and animating in a 3-D environment are crucial for 3-D animators. Therefore, the correct answer is b) Great CGI skills are not required for 2-D animation, but they are for 3-D.
