Project video on floor - rotate video screen

[holbylarsen]

Hi

 

I am looking at rigging projectors facing down, projecting on the floor. The video screen tool does not rotate 3D, so how can I achieve this?

 

Thankful for advice

Set Screen Tilt to 90º and Projector Tilt to -90º

Hi

 

Thank you, that got me started.

 

I am trying to make a projector with a .5 throw ratio and 16:10 that points straight down from a height of 3200 mm. The projector should be aligned to the bottom of the image.

 

The projection surface is not below the projector though. And if i try to shift it I get warnings about parameters being beyond limits.

I'm not sure what you're trying to achieve is possible with the Video Screen tool. You're going to have to fake it in some way. One possible approach would be to put the projector on its own layer and set it up as needed assuming the "floor" is a vertical wall. Then create a design layer viewport of the projector layer and rotate it as needed within your 3d model.

Thanks Kevin

 

Maybe in future versions there will be an option like in the truss tool. For now I ended up building it from scratch with manual calculations.
