Hello,
In an upcoming project I want to track and augment a big sculpture. It's kind of a cylinder, 3meter diameter 5m tall.
I want people to move around the cylinder and see an augmented sculpture through their tablet. They might get closer at the beginning than go few meters away and look up and down a little bit.
The tablet has to be Windows based so I can't use a combination of Vuforia + ARKit or ARCore to start positioning the virtual cylinder to the real one using a marker and than finish the tracking using SLAM. I have to use Vuforia only and their SLAM based approach is not released...
What I wanted to do is to print about 50-100 big targets, 40cm squared and to stick/hang them around the cylinder at fixed known position/orientation relative to the cylinder.
I saw that Vuforia has a multi-target feature but it seems more focused on small scale object than on big scale. Has anyone used it for larger scale objects?
Also if I want to create 50-100 targets I thought that VuMarks are a better choice has you can easily generate 100.
I though that I could use the VuMark ID to deduce its position/rotation so I could go from one vumark to the other using extended tracking if none are visible and switching from one to the other without loosing the augmentation.
Maybe using the wolrd center mode or the unified coordinate system or with custom software to get the augmentation transformation to the camera.
But in Unity the VuMark component doesn't have a predefined ID so I can't place several Vumarks around my cylinder with a fixed ID.
Any idea how to solve my problem? Any feature I didn't think of to handle this kind of problem?
Is it too optimistic?
Thanks a lot,
Ben
Hello I33N,
You can pre-generate and print out your VuMark instances. Review this documentation to get more information on this:
https://library.vuforia.com/content/vuforia-library/en/articles/Solution/Working-with-VuMarks.html
https://library.vuforia.com/articles/Solution/Using-the-VuMark-Instance-Generation-API.html
Our sample app also has a VuMark scene that has a handful of pre-generated VuMark instances if you want to see some code that handles this use case.
Alternatively, we have a new feature coming in Vuforia 7 called Model Targets which allows you to detect and track based on 3D model data. It is currently in our Early Access Program. You can get more information on this as well as apply for EAP at this link: http://info.vuforia.com/modeltargets
Thanks,
