I’ve been working to get video/image output from TD to be continuous from floor to wall (or vice versa) for a curved LED wall and flat floor.
My initial idea was using standard transforms (scaling, etc) but this needs to be adjusted per output
Another approach for this was to think of it as if it were a projected image and using grid/bezier warping, but given that this is a video wall I wasn’t sure how to apply this like you see in the mapper tools.
Does anyone have any suggestions on how to reliably have the image move from surface to surface and maintain continuity? I also feel that I’m overthinking this, but maybe someone will jostle my brain a little.
I’m looking to build a tool that is a continuous image from a curved wall to a flat floor, not a singular curved surface. I can display to a curved wall.
since it’s a LED wall and floor, do all the led tiles have the same resolution?
Are you additionally looking for a perspective distortion of the content?
If it is LED tiles, you could think about rendering the curved section as individual horizontal strips making use of the Camera COMP’s Quad Reproject feature.
The tiles should all be the same resolution, yes. The floor and wall are the same resolution, we just have a gap as the wall sits downstage some and covers the back bit of the floor tiles. Perspective distortion would be nice, but not sure that it’s absolutely crucial (though it would be nice).
if you want to make use of the QuadReproject, you would create a rectangle for the floor, a rectangle for the wall, and rectangles to approximate the curve from the flat wall to the floor. For all these you would have to know the exact resolution.
The quadReproject component from the Palette>Mapping folder, let’s you position these elements and render the 3D world around you from the sweetspot of a camera giving you the same effect as a Trompe l’oeil type projection.
if you just want to map an image onto the led, you would still need to know the resolution of each section and then adjust the uv coordinates for the continuous image to fit onto the screen.
Attached is an example with a terribly simplified stage model but hopefully the two ideas translate.
