I can add points to the grid and drag them around. would rather not.Īll the sites I go to do not even have prices for their software and if they do, they are thousands of dollars. I used wayback machine and got a free time trial copy of Nthusim to try but it only does blending, so that was no help. I use Nvidia surround on a 2070 super card. I am easy, I can live with that, but the out of focus on the sides of the curved screen are miserable. Right now I just line them up in the middle, and have a tiny line on my screen where they come together. What do cockpit builders use for 2 and 3 projectors on a curved screen? (its only the faces we care about)Ģ - unwrap the UV and it'll look a bit like this UV unwrapģ - generate a template from that UV unwrap to make sure you've not goofed rubiks unwrapĤ - if you then wanted vines to grow up the sides of the cube you could just draw them onto the 2d unwrap and save it as a video file (in HAP or DXV)ĥ - a media server (disguise for example) can then take the mesh and wrap the video back onto it, work out what the projector can and cant see and then output that as a flattened out image to a projector.Hi All: I have been searching for months, and years trying to find warping software for projectors, that does not cost a kings ransom. Lets do a rubix cube because its 3d and easy and content isn't my thing really:ġ - make a 3d cube and save it as an OBJ or wavefront file so its just a box rather than a solid thing. We used two 3,000lm Epson's and one 5,000lm so it was. It was in a store with glass walls on 3 sides in Florida during the day. It would be much worse with multiple blended projectors. MadMapper is an incredibly finicky program that makes it extremely time consuming to recover from a lone projector going out of alignment. I think it makes me do the time consuming blending process over and over instead of doing it once at the beginning.

MadMapper claims this is a more flexible way of doing things. MadMapper doesn't blend projectors it blends surfaces across projectors. Some laptops with integrated graphics and a graphics card will used the integrated graphics for USB to HDMI. MadMapper can be rented by the month $50 and the dongle is $40.Ĭons - Need a high end laptop if you are pushing a lot of pixels as you do in a complicated projection mapping show. Pros - Its a low cost set up if you have a good enough laptop. We used a laptop with a graphics card and 1 HDMI port plus a USB-C dongle with 2 HDMI ports to output to 3 projectors.

We have used MadMapper to project large walls using 2 and 3 projectors. What are the pros and cons of this method? What method have you used for blending projectors?
