Projection mapping as an external display for a computer 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.
