• PA1 Ray Casting is due on Sep 15, 11:59pm, 2016
• Code: cs451-PA01.7z (last update: 9/15/2016)
• Solution: cs451-PA01-solution.7z (last update: 9/21/2016)
  • OpenGL ray viewer code: cs451-rt-viewer.7z (last update: 9/15/2016)

• This assignment will help you deepen the understanding of the following topics
  • Ray generation
  • Ray-sphere Intersection
  • Basic shading (Diffusion, Specular, and Ambient)
• What to submit
  • Your code (with everything)
  • You RT file (name it cs451_pa01.rt)
  • Rendered images. Make sure that you name your images as follows
    • 6 images with 1, 10, 100 rays per pixel using orthogonal and perspective cameras
      • name these images cs451_pa01_ortho_0001.jpg, cs451_pa01_ortho_0010.jpg, cs451_pa01_ortho_0100.jpg, cs451_pa01_persp_0001.jpg, cs451_pa01_persp_0010.jpg, cs451_pa01_persp_0100.jpg
  • README.txt file in cs451-PA01 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 (30%): Generate rays for both orthogonal and perspective cameras
• Task 2 (20%): Compute Intersection between rays and the spheres
• Task 3 (20%): Determine the normal direction of the intersection point
• Task 4 (20%): Determine the color of the ray
• Task 5 (5%): Create your own *.RT file.
• Task 6 (5%): Compelete the README file.

Examples:
