3D Model geolocation scale

I have read that default implementation fo Wikitude 3D model implementation is : 

The scaling of 3D models is relative to the target. That is, the smaller the target, the smaller the augmented 3D model. 


Can I disable this automatic scaling? 

I want to have same target model size irrespective of the distance to the target model. 


For example, i want same model size whether it is at 1KM or 8KM. 


I have tried scale property of the Model but it is not giving the result as expected as it doesn't allow to specify the same scale for all the distance.

Hi Hardik,



for our tracking algorithms in the JavaScript API you cannot change that behaviour. We perform our rendering with a perspective projection matrix, causing object to naturally decrease in size as you distance yourself from them. That's just the way the human vision works and how cameras work; augmentations that behave otherwise would immediately stand out strangely.


If you are using our Geo feature you might be able to do that by employing a feature that sort-of does what you are asking but was intended for a different purpose; distance based scaling.


Otherwise you will have to use our native API. With that you can do any king of rendering you desire; but have to implement it yourself. We provide everything else, but the rendering is yours to do.
