Possibility of shooting some tests with a model car but I am thinking of lighting it with moving images, probably back projected.
I might need a couple of projectors, maybe three but I'm wondering how one gets a very clean stitch/join between different
sources. I'm going to shoot multicam captures on a moving car first to then project say 270 degrees of back projection. Also
if the screens are curved what software handles that kind of curved projected calculation? The other option is to create some CG
backgrounds as well so distortion/lens angle can be altered to suit. Maybe front projection is better? (thinking of Oblivion here)

With modern projection mapping it’s possible to get very clean stitching/blending between multiple projectors to create a seamless image. On the high end there’s software/hardware combination systems like those offered by Disguise (formerly d3 Technologies) or Green Hippo, with a plethora of other options at very price points and levels of sophistication / capability going down from there. Curved screens and even more complex geometry (like projecting onto non-flat surfaces) are no problem for most higher-end systems.
Depending on the parameters / budget you might also consider using LED video walls instead of projection – a technique that’s becoming more popular and has the advantage of being able to project interactive light onto the “live” subject and create more realistic reflections on specular surfaces so they don’t all have to be added in post.
I’d recommend talking to a company that specializes in live events projection mapping (and there are many in London, which is something of a hub for the technology) rather than trying to figure it all out yourself – it’s quite a deep rabbit hole to dive down in terms of working out the nitty gritty details of building a setup. Many of these companies also have special/proprietary software and hardware tools they can bring to the table that aren’t available on the open market – from what I’ve observed (at least in the US market) projection mapping systems rentals tend to be packaged as an inclusive “turnkey” service where one company supplies hardware, software, design consultation and sometimes personnel to make it all work.
