Is it possible to detect two image target and then dynamically generate a hologram that fits between
I am starting a new concept project with the following requirements;
Using a HoloLens device, view a physical wall that has a physical poster on it. Assume the poster is generic and can be of a variety of sizes so it is not, itself, a good candidate for an image target. However, the poster will have two image targets or some kind of detectable spatial anchors, one at the top/left and one at the bottom/right of the poster.
Using the coordinates of the two tags/anchors, dynamically generate a gameObject rectangle that is sized to fill the area between the top/left and bottom/right points, but only show the rectangle outline so it appears to outline the poster and not cover it. Then, within that rectangle outline, create a grid calculated from the area between the top/left and bottom right.
With the grid created, I then want to dynamically highlight cells in the grid based upon data input, such as a USB or Bluetooth device keyboard or scanner, for example).
The highlighted cell should be translucent so as not to occlude the information on the poster, it just highlights it.
The highlight should remain in that fixed position even if the user is not gazing directly at it.
The highlight will only disappear when new data input is detected that then highlights a new cell in the grid over the poster.
Ideally, I would like to be able to test this using the HoloLens Emulator, if possible. So using Vuforia for the image target (or Vumark) may not be an option since, as I understand it, Vuforia does not currently offer the ability to detect image targets or Vumarks using the HoloLens Emulator.
Is any of this even possible using the current versions of Unity3D and the HoloLens Emulator?
Thanks in advance for any help you can provide.
