We looked into what would need to be done/what programs would need to be used in order to create this 3D render walkthrough. Whatever we came up with had to work for the ping pong visualisation and be able to be easily used for other pavilions that may need the same visualisation done when they are completed.

The biggest problem we found was the overlaying of the original ping pong type video over top of the walkthrough video and how we get it distort and move to track the screens as the walkthrough moves through the space. We found that the easiest way would be to insert the video into the actual 3D rendered environment and record that as overlaying it inside After Effects or Premiere Pro would be very time consuming and wouldn't look nearly as good. We ended up looking into programs like:
– SketchUp
– Twinmotion
– CryEngine
– Cinema 4D
Each one had limitations to the actual inserting and playing of videos within the space. CryEngine was the best option as it created amazing renders and was able to have videos inserted with the help of plugins. As we looked into it and talked to people we found that it just wasn't possible for us to do due to actual equipment constraints and how complicated it was.
We ended up deciding that the best way to do it was to split the focuses into two visualisation techniques:
– EXPERIENCE - rendered stills overplayed with the type videos. Importing a SketchUp model into SkIndigo and overlaying the original type video with After Effects
– SPATIAL - 3D rendered space walkthrough. Importing a SketchUp model into Twinmotion and recording the walkthrough
We found that splitting the visualisation into two sections still clearly communicates the idea just as well as the CryEngine technique.
