Graphing Calculator v1.12
 

As a side project, I am working on a Graphing Calculator for the Zen;

Version 1.2 released (see below for attachment)

• The ui is from Transparent Glass (http://sixrevisions.com/freebies/web-page-templates/transparent-glass-ui/)

• The Icon is from (http://www.iconfinder.com/icondetail...aph_stock_icon)

Todo:

• Add the ability to use inverse trig functions (asin, acos, and atan)

Cool project.
I would like to know more about how you managed dramatic fps increase.
Did you managed to find out how to draw pixels faster?

The fps increase is only theoretical so far, I am still preparing a test app. Basically the framework uses atlasing, which is where there are multiple images in the same image file, similar to a sprite sheet. The reason it should be faster is that (wiki). With that being said, awhile ago I found out that there are image size limitations for the Zen, which if I remember correctly are only imposed on the y axis.

Version 1.0 is released, check the top post for information and the download link.

Version 1.1 is released, check the top post for the new download. The app now uses a new version of the framework (with an automatic texture packing parser).

Version 1.11 released, over 200 lines of code have been removed. All of the screens now use a built in ui library that handles buttons automatically.

Version 1.12 is released, it will no longer crash on the Zen.
