Render Surface & Outputs

*Reminder:
A Render Surface is a rendering area where all the media are composited.
A V-Node needs a Render Surface affected to it to be able to display content.
An Output then uses a portion of the Render Surface. This portion is defined by the MAP.
MAPs can be defined on the output itself, or on any number of X-Maps created on an Output.

Render Surface

There are two ways to approach our render surface in this project.

Since the projectors on the cyclo screen share an overlap of 384 pixels, we could take this into account when calculating the pixel workspace and stick everything together. This would result in an overall width of (1920×4)-384 = 7296 pixels.

Since this is a virtual workspace and we assign whichever portions of it to our outputs, it can be more practical to leave an “unused portion” in our pixel workspace and simply work with an overall width of (1920×4) = 7680 pixels.

This has the advantage of simplifying media position coordinates and in some situations can make working in conjunction with a video matrix easier as well.

Create a Render Surface with a size of 7680×1080 pixels. This results in the following:

*Note: All numeric inputs in Kinetic Designer accept mathematical operators.

Outputs

Create 4 Outputs on the V-Node and configure them as such:

If you are running in demo mode you can only display one output at a time but everything you prepare here will work when you load this project into a Kinetic Designer connected to a V-Node server.

Select all the outputs.

In the Shape tab set the Test Pattern to Softedge.
