One more example of a video-feedback rendering system.
A camera, slowly rotating, is in the center of a cube; the image captured by the camera is pushed through a few different colour transformations, and the results of those are painted onto the walls of the cube in the next frame. Zoomy rainbow trips ensue.
A "Combine image with feedback" node is included in the feedback loop, which blends the new frame with the previous one at a specified opacity. This arrests some intense strobing effects which would otherwise occur, and lends the image a softer, dreamier quality.
How to load Vuo Image Generator compositions and how to manipulate Vuo's inputs (published ports) from within VDMX
Transcript:
Hi! I’m Jean Marie from Team Vuo. Vuo compositions can be used in other applications. In this tutorial we’ll cover how to use a specific type of Vuo composition, one that conforms to Image Generator protocol, as input to VDMX.
OK, let’s get started. Here I’m using VDMX’s simple mixer template, and I’ve already moved the crossfader all the way to the left, so we are looking at the left screen. I’m going to drag my Vuo composition into a media bin.
It takes moment to compile the first time, but after that it will be available right away.
This image generator composition shows seven 3D objects made of points with several changeable parameters, including the 3D camera position. This composition in used in a tutorial on how to use image generator compositions in VDMX.
