Perspective and LookAt

Getting a better view

Setup

I have updated code on the examples repo on github. Start by checking the status of your personal examples repo using git status and committing any local changes. Refer to git status help page for instructions, particularly on files that have been modified.

Next, fetch upstream changes. If you have committed local changes, merge conflicts should be minimal 

[~]$ cd ~/cs40/examples
[examples]$ git fetch upstream
[examples]$ git merge upstream/master
[examples]$ git push

Open up a terminal and navigate to sphere directory in w05-perspective. You will be creating a symlink to a folder containing texture map images for this code. You need to do this step before running make in your build directory. 

[~]$ cd ~/cs40/examples/w05-perspective
[w05-perspective]$ ln -s /usr/local/doc/textures data

In a second terminal, navigate to the build folder and run make -j8 to get the w05-perspective folder. 

[~]$ cd ~/cs40/examples/build/
[build]$ make -j8
[build]$ cd w05-perspective
[w05-perspective]$ ./perspective

Exercises

Sketch the scene. Where are the centers of the sphere? What are their radii in world coordinates?

Toggle the Ortho/Perspective projection matrix

Modify the LookAt matrix to view from above the $\hat{y}$ axis.

Add a keybinding to change the field of view in the $y$ direction.

Open up a terminal and navigate to sphere directory in w06-lighting to browse code. You do not need to make a data symlink in this folder

In a second terminal, navigate to the build folder and run make -j8 to get the w06-lighting folder. 

[~]$ cd ~/cs40/examples/build/
[build]$ make -j8
[build]$ cd w06-lighting
[w05-lighting]$ ./phong
