House Model AR 1.6

This Augmented Reality application is a techdemo which features both the Unity3d game engine and the Qualcomm Vuforia marker tracker software plugin for Unity3d. Vuforia is the best AR tracking software available for Android at the moment. The tracking quality and speed is superior to alternatives like ARToolKit. The only thing which is better is String but that one is extremely expensive if you want to publish your work and also not available for Android yet.

This demo can be used to view a model of a house (Shadow Demo of Unity3d) using a marker (picture of stones). The marker can be downloaded from slingame.com and is free. You need to print it out and place it in the view of the camera.

The app also features the Vectrosity plugin for Unity3d. You can use it to render line objects and is very cheap. Highly recommended. Tap the hardware menu button, then add the geometry by selecting the appropriate button. Select the created geometry by tapping on it (it will turn red when selected) and drag or pinch to zoom with the correct button selected at the same time.

In the demo, some lights can be switched on and off using the menu on the bottom left. A framerate counter is also shown at the bottom. Some objects can be moved around by dragging them with your finger.

The reason why this app requires permissions like network, wifi, and internet. is because the Vuforia package needs to download some camera parameters from their server the first time this app is run.

This app runs on ARMv7 processors only. This is a Unity3d limitation.

Changelog:
v1.0
- first release

v1.1
- Changed location where the user has to tap the screen to show the camera options window (focus, flash) to the top left.

-Added an option to add additional line geometry such as a grid, cube, or cylinder. You can scale it and move it around.
