Compute camera position
I would like to use unity for projection and I need to calibrate the projector relative to the real world. In blender I use BLAM (http://www.blendernation.com/2012/01/23/blam-geometry-camera-matching-add-on/) to do this and it computes the position of the camera and helps me project on the 3d space.
Using unity can I achieve this?
To go in detail I have a unit cube and the world is relative to it. I could match the corners of the cube from the projector and would like to compute the position of the projector in unity using the co ordinates and recreate my scene in unity for projection.
Is there a better way to go about this or any tool which I can use?
I do this using augmented reality toolkits like Vuforia and others. Put some markers (in this case, on your cube) and calibrate them in real world.
Yes but I have to reproject on the cube so I need the position of the projector in real world so I can map that postion to a camera and render its view.
Based on your suggestion I tried to run AR toolkit on mac. It is rather difficult to work with it. Their documentation says use exview. But their prebuilt binaries don't include the tool. I cannot build the source because they only support 32 bit. I tried the linux version on an ubuntu. I still had the 32,64 bit problem. Seems to me like this is old and not being supported or rather made a commercial product with toolkit v4. Any other suggestions? I appreciate your time
