Implementation of portals for VR (Oculus Rift)

PortalVR

A implementation of stereoscopic portals for virtual reality (VR). Supports only the Oculus Rift.

Based off of Tom Hulton-Harrop's tutorial, Portal Rendering with Offscreen Render Targets.

portalvr's Issues

Deal w/ head and hands

It might be worth to not support the localavatar hands because then we could treat the hands as normal objects

Improve depth masking system

Right now the depth mask that hides objects passing through the portal is mostly too large and doesn't adjust to the object passing through. Maybe compute a bounding box for a specific object and reshape the depth mask cube based off of that?

Make the portal camera for a given frame not render its own frame.

I believe this would have a more natural effect when you look through the portal.

Implement single pass stereo rendering

This should bring performance gains. See more here.

Teleportation of objects after they've moved through a portal

When should objects actually teleport? When they've exited the other side of the portal? When the hand that's grabbing it has passed through? When the hand releases it?

Render parts of objects that have moved through the portal invisible

This way you can't look at the other side of the portal and see the object sticking halfway through it. Maybe bounding box on that portion + depth masks or stencil masks?
