Realtime Portal: a TouchDesigner Base

A portal, as a TouchDesigner Base

I needed a portal for a project. A clean alpha cutout that opens, holds, then closes, with a separate soft mask for downstream blur and a wobble that doesn't look like a logo animation. So I built one as a single TouchDesigner Base.

Generate a portal with alpha support and a separate mask.

Custom parameters

The Base exposes everything you actually want to tweak:

• Fade duration for position transformations
• Open time, how long the portal stays open
• Render resolution for the inner texture size
• Color, RGBA with alpha
• Wobble intensity, distortion amount on the edge

Drop it into your project, wire it to a trigger CHOP, done.

This eventually became the PORTAL project. See it in works.
