• PA8 Ambient Occlusion is due on Dec 16, 11:59pm
• Code: cs451-PA8.7z Δ
• This assignment will help you deepen the understanding of the following topics
  • Ray generation in a hemisphere centered at a point
  • ambient occlusion
• What to submit
  • Your code (with everything)
  • You RT file (name it cs451_pa8.rt)
  • Rendered images. Make sure that you name your images as follows
    • two 680x680 images, one without ambient occlusion and one with ambient occlusion
    • name these images cs451_pa8_No_AO.jpg and cs451_pa8_AO.jpg
    • create these images with 30 rays per pixel and 30 rays for ambient occlusion approximation
  • README.txt file in cs451-PA8 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 did not start
    • What are the known bugs in your code?
• How to submit
  • email me (jmlien@cs.gmu.edu) and your TA (ple13@masonlive.gmu.edu) a link to all source code, images and README.txt in a file named cs451_pa8_[your last name].zip
  • Please do not send us the file directly

Tasks

• Task 1 (5%): Blend ambient occlusion with ray color
• Task 2 (90%): Compute Ambient occlusion of a given point on the surface of a mesh
• Task 3 (5%): Create your own *.RT file.
