Task07: Multiple Importance Sampling (Brdf sampling, Light sampling)

Deadline: June 6th (Thu) at 15:00pm

If you have not done the task01, task02 do it first to set up the C++ development environment.

Follow this document to submit the assignment, In a nutshell, before doing the assignment,

make sure you synchronized the main branch of your local repository to that of remote repository.
make sure you created branch task07 from main branch.
make sure you are currently in the task07 branch (use git branch -a command).

Now you are ready to go!

Implement light sampling by lighting a single line code around line #364
Implement Brdf sampling by lighting a single line code around line #383
Implement MIS sampling by lighting a few lines of code around line #401 around line #403

Run the program with Release mode and it will generate three images that replace the images below.

Light sampling	Brdf sampling	MIS sampling

Observe that three image looks similar but the noise is reduced by MIS sampling.

After modify the code, push the code and submit a pull request. Make sure your pull request only contains the files you edited. Good luck!
