P A02-Ray Tracing

• PA02 Ray Tracing is due on Sept 29, 11:59pm
• Code: cs451-PA02.7z
• Solution: cs451-PA02-solution.7z
• This assignment will help you deepen the understanding of the following topics
  • Ray generation from refraction and reflection
  • Ray-triangle Intersection
  • Soft shadows
  • Basic Lighting (Diffusion, Specular, Ambient)
• What to submit
  • Your code (with everything)
  • You RT file (name it cs451_pa02.rt)
  • Rendered images. Make sure that you name your images as follows
    • 3 images with 1, 10, 100 rays per pixel with image resolution 680 by 680 or higher using a perspective camera
      • name these images cs451_pa02_0001.jpg, cs451_pa02_0010.jpg, cs451_pa02_0100.jpg
  • README.txt file in cs451-PA02 folder with the following information
    • The OS and compiler that you compile your code
    • How to build your program
    • Tasks that you completed
    • Tasks that you started but did not complete
    • Tasks that you did not start
    • What are the known bugs in your code?
• How to submit
  • Submit your files in a single zip file on blackboard.
  • Please do not send us the file directly

Tasks

• Task 1 (20%): Compute Intersection between ray and a triangle
• Task 2 (25%): Determine reflection color
• Task 3 (25%): Determine refraction color
• Task 4 (25%): create soft shadows
• Task 5 (5%): Create your own *.RT file.
