Yes this is a problem with building projections, whether by LED’s projecting light out or projectors projecting light onto the surface. If you’re not in the sweet spot for viewing it doesn’t read as well. Which is why a display like this would need different visual content running over time for different effects and aesthetic results. I think the curvature of the LED’s on the corner sell this effect from this perspective.
I would love to have access to this screen space as an artistic canvas. Unfortunately I would think that the video content would be sold to the client from a 3D render that only sells this perspective.
Fluid sims are a great way to create a certain sort of optics which melds with the geometry of the actual structure. But in real life this screen will be an imposition on the folk who have to live with it in their daily life, pedestrians, people in surrounding buildings, as well as the folk in this building etc. which means that for these urban installations it is important to consider the common denominator of viewing experiences.
I’m hoping that this is more than a demonstration of LED tech. A visual canvas that is more meaningful to the folk that have to see it everyday!
