Vuforia 7 Plane - Custom Interactive Hit Test

Hello,

I just downloaded Unity 2017.3 and trying out with the GroundPlane example from Vuforia. I understand most of it. But I just wonder how to make custom interactive hit test, the example provides an solution for detection hit result on where user's finger input. What if I want to make it return hit test result from the center of the screen? Like shooting a bullet from the center? Is it just a simple physics raycast?

thanks in advance.

Just fire a raycast from center of screen in the direction the camera faces, then check for the intersect point and thats your anchor.

 

Thanks for your reply, do you know what layer does it has? I might need to raycast it with a specific layer.

 

Default layer, called Ground Plane Stage, just set your own layer or tag to make it easier.

 

Thanks! this clears things out for me.

 

Hi Gamrek (Derek)

How did you manage to get Vuforia 7 to work and on what device? I too tried https://library.vuforia.com/articles/Solution/ground-plane-guide.html.
But the samples didn't worked, It could be I have an Note 8 (Exynos) and Pixel 2 XL, both of which are not listed in the supported Device List.

 

Sorry, i didn't deploy on on device, I was only trying on editor to understand how it works at the first place.

 

I also just installed Unity 2017.3 and Vuforia Groundplane, but on my Galaxy S7 no ground is detected.
Is Unity 2017.3 Patch 1 really needed?
It´s not available in the downloads...

PS: Also on an S8 no ground detected
PPS: Vuforia Ducumentation:
NOTE: The initial release of Vuforia Ground Plane in Unity 2017.3 (Vuforia v7.0.36) supports ARKit enabled iOS devices. Android devices and non-ARKIt enabled iOS devices are supported in Unity 2017.3 Patch 1 (Vuforia 7.0.40). See Supported Device List for the latest device coverage. New devices are added frequently.

 

Okay, got a reply from Vuforia Support, the patch will be released in January.

Does anyone know that if enable groundplane on current version will mean using ARKit on the device by default? Also how do I enable ambient light estimation?

Hello,
Could you please make a tutorial how to raycast an object in Vuforia plane detection?
I followed https://library.vuforia.com/articles/Solution/ground-plane-guide.html to place a car.
But now, I would like to turn on/off the headlight by clicking on object.
My script works on 2D camera, but not AR Camera.
Pls help me!
Thank

 

You add a collider and a rigidbody to the object you want to interact with. Then you make a script with OnMouseDown method and inside you add functionality, like turning on/off lights.
