Today I revisited my previous work that around stage design "2015 KCON in Los Angeles" in VR. I converted 3D modeling to VR space through IrisVR. I was astonished by how immersive the experience felt. In particular, the fact that I can check 1:1 scale with various perspective was amazing. I can visualize the entire space in VR. Now does this mean we don't need to build physical mock-up in the future? After drafting & 3D modeling, I used to make a physical mock-up in the different scales to check the performers' and audiences' views and for the purpose of efficiency sharing my vision. Maybe we still need a mock-up to play around physical objects to check materials and movements. But for the scale, VR definitely makes it easy to share the sense of scalability.
