projection mapping onto curved surface

in General Discussion • Other • 6 months ago

I need to map a sketch to a curved surface in a C shape, its a panoramic screen that curves towards you similar to this http://www.scientificamerican.com/media/inline/blog/Image/RPI-EMPAC.jpg

I made a sketch that uses basic processing vector objects: lines/circles/rendered text and now need to do some projection mapping into a curved surface, I thought this would work: http://www.iact.umontreal.ca/mappingtools/ but not sure if this is just for video/images, can't seem to get it to work with regular sketch.

http://keystonep5.sourceforge.net/ also seemed interesting but I needed to have more control like bezier curves for the curved surface, so this is a no go.

any ideas?

hey lukasz,

could you do your vector drawing to an offscreen PGraphics, then pass that PGraphics through the library's render() ?

similar to this example: http://www.iact.umontreal.ca/mappingtools/examples/BezierWarp_offscreen/BezierWarp_offscreen.pde

but just using the built in Pgraphics offscreen functions rather than GLGraphics, as explained here: http://processing.org/reference/PGraphics_beginDraw_.html

Just a thought. Hope it helps.
