Hi,
I would like to generate a series of frames in realtime. When every
new frame is created I want all the previous frames to be translated
to the left(or any other direction for that matter), so that it looks
like something groving sideways. Every new fram i generated in the
same location, just the previous frames are moved.How can I do this using GEM?
Texture feedback is one way. You can use [pix_snap2tex] to capture the render window to a texture, then texture it on a rectangle translated slightly to the left (or any other direction).
Unfortunately my video drivers are currently broken so I can't make an example right now.
See attached.
