What is the primary advantage of using Phong shading over Gouraud shading?
Understand the Problem
The question is asking about the advantages of Phong shading compared to Gouraud shading in computer graphics. Specifically, it is inquiring which option correctly identifies the key advantage of Phong shading.
Answer
Phong shading handles highlights more realistically and effectively than Gouraud shading.
The primary advantage of Phong shading over Gouraud shading is that it produces more realistic highlights on surfaces, reducing the Mach-band effect and handling highlights better.
Answer for screen readers
The primary advantage of Phong shading over Gouraud shading is that it produces more realistic highlights on surfaces, reducing the Mach-band effect and handling highlights better.
More Information
Phong shading interpolates normal vectors across surfaces and computes light reflection for each pixel, providing a smoother and more continuous highlight effect.
Tips
A common mistake is not distinguishing between Gouraud shading's interpolation of colors and Phong's interpolation of normals, leading to different visual outcomes.
