advanced video mapping

advanced techniques for projection mapping onto architecture - I developed this method myself.

please note - since making this clip I have found that camera angle of view is only critical with very wide and very narrow angles. so you only need to be accurate in selecting a camera lens if you are doing very short or long throw projections - what is important is that the camera lens is in exactly the same position as the projector lens

Once i have created the mask and projected the image back through the projector,how would i get each of the buttons and dials to light up a different color and not all the same video footage?

[deepvisual]

@ATGxQuadPimp either, use different video for each button, or use one video with lots of different coloured areas .. you could globally change these using a filter or the inbuilt color correction in M8

thanks for getting back. I take it you mean that when I take the picture I need to make sure I've 'cropped' the image size of the camera to the size of the projected screen......as near as possible?

@fiftynorth

no not at all.

use a focal length that has the same throw ratio/lens angle as the projector lens.

this technique only works if you use the same lens angle on both projector and camera.

I wish i could do stuff like that. Wish i had the imagination anymore.

When can we expect to see this applied to common concerts and festivals?

@roskildahphreak

there was a major mapping installation at glastonbury this year!

@deepvisual I'm using Resolume on a PC,but i assume it's similar in purpose to M8,i just can't figure out how to add a different video to each map. It's probably so simple,the penny just hasn't dropped yet. Thanks for your response.

Awesome. Thanks for the info. :)

this stuff is the way of video art future... i love it!

@deepvisual Nice!

@fiftynorth

maybe. try keep the zoom in the relevant area, so the lens ratios are the same
