TestLines

TestLines is a fantastic software program that is not only free but also open source, making it accessible to anyone who wants to improve their line-drawing speed. The software's main function is to draw a specific number of lines per update, with a target of 60 updates per second. The application then displays the average update rate as "fps" (frames per second).

One of the highlights of TestLines is its ability to calculate the average number of lines that can be drawn per second if it were not performing any other tasks. This calculation is determined by dividing the number of lines drawn by the time taken by the drawing routine.

TestLines is a great example of how to program for Mac OS X using the Cocoa API. It uses separate Model, View, and Controller classes for ease of use and efficiency. Furthermore, the software also utilizes bindings and NSTimer to provide regular updates.

To sum up, TestLines is an excellent software program that is perfect for anyone looking to improve their line-drawing speed. Its free and open-source nature gives anyone the accessibility to take advantage of its fantastic features, while its use of the Cocoa API highlights the best software programming practices.
