I'm using a projector to display the content of my computer, as one would do with a regular screen. Now I want to do the projection on several panels that have different orientations. Hence I'm looking for a projection mapping solution.

Is it possible to do projection mapping with the HDMI output of my computer as projected content? If it is, could you recommend me a tool to do so? So far, the projection mapping softwares I've found can only project content that is internal to the computer and defined in advance, such as solid colors, video or pictures.

Youre likely going to have a tough time accomplishing this without the right toolset.

Im not aware of any opensource projection mapping software that could accurately output a signal to a projector or series of projectors to accomplish a decent map.

Christie (you can visit their website and search youtube for examples) is the only projection mapping software / hardware solution Ive toyed with... back when I had two Christie HD10K rigs.

But good projection mapping typically requires at least 4 projectors all tied into the same video engine. You need up down left and right, otherwise shadows will be a major issue.

Typically, 6 or 8 units are used on a single simple object for wrap around effects.
