SuperImpose 3D CAD Models

December 4, 2017 - 1:18am #1


How to Super Impose a 3D CAD model on to the real equipment, so that we can highlight some elements from it.

I tried in Unity 2017.2, When i scan a QR code  the Model is Placed on top of it, taking the QR code as Origin. I want to Activate or enable the model back of the QR code,as it is placed on to the equipment, in this way i can superimpose the model and highlight some elements.

These are some examples what i am trying to achive




Please do help me, i am stuck with this implementation. Not able to Hold the Model always moving and on top of the QR code.

Kindly waiting for some help.

Thank You.

Hello @Samih,

You can find a mesh as output by the Model Target generator. One is a GLTF in Ascii format (".gltf"), along with binary asset files (".bin"). These assets are *not* included in the Model Targets device database. It is up to you to package it with your project/app.

Please see https://library.vuforia.com/content/vuforia-library/en/articles/Solution/introduction-model-targets-unity.html for more information.

Hello there,

I am not able to superimpose a 3D CAD model on top of a physical model on HoloLens. I can see the guide view through the HoloLens and when the model is detected the guide view disappears and the CAD model is not shown. I assume that this should be by default in Vuforia Model target.

any advice?

I am using:

- Vuforia 8.0.10

- latest Model Target Generator (MTG) for generating the Model Target.

- Unity 2018.2

Hello ICLDev1,

You'll need to set up your augmentation to be offset from the origin of your target in Unity relative to where it will be to the target on your physical model. This will likely require some trial and error to get the alignment correct.

Alternatively, our upcoming Model Targets feature will use a CAD model as the detection target. Model Targets will be available in the upcoming Vuforia 7, but are currently available in our Early Access Program which you can learn more about here: http://info.vuforia.com/modeltargets

The Model Targets feature will augment the CAD Model over the physical model by default and will be more accurate that using an Image Target or QR code.
