## What is Neotrie VR?

NeoTrie VR is a new software package which is currently being developed by Virtual Dor, a spin-off of the University of Almería, that enables users to create, manipulate, and interact with 3D geometrical objects and 3D models in general, of several types.

It is being used and tested for educational purposes, through the european platform Scientix. You can see more information at:

## Quick start

1. Choose your Language and avatar, hair color. You can write your name on the screen of the PC.
2. **Start game** with your hand to get into the temple of Neotrie: "Lan session" for local multiplayer mode (Online multiplayer soon available).
3. Euclid will guide your first steps and show you how to use the basic modes of your hands, and some tool.
4. The "Lantern" can be caught with the **Trigger Button** (nr 3), but there are no objects yet. You will have to create some object first to see their shadows.
5. Say "dodecahedron" to get this figure in front of your eyes, and then move the light to see the shadows. Neotrie has hundreds of figures which appear in the scene thanks to its SRS (Speech Recogntion System).
6. **Grip Button** (nr 4 for HTC Vive, nr 1 for Oculus Rift, Windows Mixed Reality) allows you to TELETEPORT inside and outside the temple.
7. Grip Button also allows you to FLY: choose the "bird" in the Menu (see below).
8. If you press the **System Button**, incidentally you will go out the game, to come back, press again the **System button**.
