What’s CG?<br />
• <strong>Computer</strong> <strong>Graphics</strong>.<br />
• Mainly focusing on 3D graphics.<br />
• Displaying a realistic virtual environment by<br />
computers.<br />
• Or synthesizing virtual objects in the real world.<br />

What’s CG? (cont.)<br />
• Or displaying a virtual world with specific styles.<br />
(e.g. non-pho<strong>to</strong>realistic rendering)<br />
• CG tech. is the foundation of modern 3D<br />
animation, special effects and games.<br />
