The four of us will be alone in the lab for today as Kevin is on leave and Ming Hong will only be back tomorrow. So Leonard and I started looking for patches that would allow us to draw in Quartz Composer which is needed for the Overlay Board (WhiteBoard app).
After some research and trying out some patches found, we found another patch which is called 'Kineme Particles Tool'. Just before we left the lab for the day, we managed to do some 'drawing' using the patch after some editing to the patch itself.

We continued testing the drawing function of the application and we found that the frame rate will drop drastically as we continue to draw. We told Ming Hong about our findings and he told us that it was because the patch stores the number of points in order to do the drawing.
And so he suggested us to store 2 coordinates instead of all the points. He also explained how we can use of viewport, ortho in our drawing application. We started create a simple application using all these patches that we change the first coordinates of the GL Line using the left-click and the 2nd coordinates using the right-click with the help from Ming Hong.

Today is Christmas Eve and we will only be here for half a day. We researched more on the use of GL tools because the 'Line', 'Point' will automatically be drawn once the patch is drag into the project.

Merry Christmas!

A day off was given by Kevin
Reflections:
This week, I learn more about GL Tools and a little about 3-Dimensional Graphics. I also managed to get a better understanding how Quartz Composer work and their limitations.
