3D Graph

3D graph OpenGL is Android application for drawing mathematical equations in form of 3D graph. It uses OpenGL ES 1.0 library for visualization. 

You can write whatever equation you like and use variables x and y as you like. It is possible to rotate 3D graph by moving finger across the screen and zoom in and out with + and - buttons at the bottom of the screen.

There are some predefined great looking equations available by opening menu and select Favorites option. You can add equation to list of favorites with star button, and take picture of it with camera button which will be saved to 3DGraph folder on SD card.

Free Ad supported version is available on Android Market.
If you like you can buy Ad-Free version at Amazon AppStore.
