Basic VR with Unity primitives and HTC Vive
Start Unity (You may need to set up an account)
Give your project a name such as Primitive_Tutorial. This will create a folder with folders inside.
Save to the Desktop or your external drive.
Select Create Project.
(If there is a Services tab, right mouse over the tab, select Close Tab.)
Make sure the main view is the Scene tab.
Add some primitives
The nice thing about primitives is the collision boundaries are already set up.
Choose GameObject->3D Object->Cube etc. Use a Cube for the floor, scale it down in the Y axis.
Hand moves view, Move Tool, Rotate Tool, Scale Tool ,Rectangle Select, Move rotate scale tool.
Check the Inspector tab on the right, Scale should be around 15, .1, 15 x,y,z for the floor cube.
Set Position to 0, -.05, 0
You can re-name the floor in the Inspector tab.
Add more primitive shapes, place them above the floor.
Use the Alt key to move the camera around in the scene.
Click an axis such as X in with the XYZ axis to look down the X axis.
You can toggle between Persp, Iso and 2D by clicking on the word below the axis.
