Week 8 – 17.11 VR Portal Development – Render Texture

Render Texture VR Portal

I worked on implementing a VR portal system using render textures. The idea behind this approach was to create a seamless and immersive portal experience that could enable flexible scene transitions. However, while testing in VR, I encountered an issue with incorrect stereoscopic (dual-eye) parallax, which impacted the visual fidelity of the portal. Since the parallax problem couldn’t be resolved effectively, I opted to use a stencil layer-based portal implementation instead.

How Render Textures Were Used

To create the portal effect, I placed a secondary camera (Portal Camera) in the destination scene and rendered its view onto a Render Texture, which was applied to the portal’s surface. The Portal Camera’s position and rotation were dynamically adjusted based on the player’s movement, making the portal act like a window into another space and creating a convincing perspective.
