ARCHE

ARCHE is a rail-shooter game playable in a cylindrical C.A.V.E

(Cave Automatic Virtual Environment).

The game is my first year school project and was developped with Unity 3D within 3 months and a team of 6 students.

The main idea is to have a 360° field of view inside a defense turret mounted into a spaceship. The player is sat at the center of the cave and aim by rotating the chair.

The biggest challenge I had was to find out how to project the image on a cylindrical screen and also how to retrieve the orientation of the chair. I was also responsible of the AI and the turret gameplay.

4 screen display with Eyefinity We had to use a special GPU capable of 4 video outputs at the same time in order to have a 360° field of view (4 video projectors were used : front/back - left/right) Using a 4 screen display is quite awesome ! Especially when you're a student :)	Top view of the installation Here is what ARCHE's installation looked like from a top view. The player (our Sound Designer Martin Bussy Pâris here) was at the center of the CAVE and could aim using a rotating chair.	Side view of the installation 4 video projectors were used. We couldn't afford 4 HD projectors (student budget) so we had to use a resolution of 800600 for a total of 3200600 pixels to display
	Projector adjustments We had to adjust the position and settings of each projectors in order to have the same image at each side. This was really cheap because we did have any professional equipment. (you can see the gap between two projected images on the left)
Thanks to The game was made with Unity3D. We used an ATI GPU with Eyefinity to output 4 screens at the same time. The audio engine used was Wwise and all the models were made with 3ds max.	The ATI Radeon HD 6950	WIP installation

	Metal was not an option Because of our budget we used plastic PVC for the armature.
Projector setup Accuracy was our primary target... :)	Wires everywhere	working from the inside
Inside ARCHE We had to cover te top of the installation for acoustic reasons in order to get the best audio experience possible.
Wiimote gear We used the wiimote accelerometers to retreive the orientation of the chair. The gear was made of wood.	screenshots of the game	final model of the ARCHE
