LIMIT for polygon numbers in a 3d obj

May 6, 2019 - 3:16am #1

Hello,

we are thinking of an AR app using Unity + Vuforia, that will use a 3D model in OBJ format imported in Unity.

The 3D model is a 3D scan of a human head.

The AR app must be able to view / render the model; in addition obviously, using image target in Vuforia, when the real target, for example a printed page, will be rotated the 3D model will rotate and the user will be able to views the 3d model from different angles.

 

based on what I wrote, is there a numer of poligons in the 3D model,  that it is better to not overcome, in order to have good performance on mobile smartphones?

 

 

Kind regards,

Matt

Hello,

In my opinion, this is a difficult topic to provide guidance with something like "do not exceed X polygons" because Android device performance can vary greatly. Additionally, most modern mobile devices have been optimized for rendering, but can struggle with rendering + Vuforia Engine SDK processing requirements.

Thus, the only real guidance I can provide is to pick the least performant model your app will support, and then build your requirements to meet "good performance" on that device.

Thanks,

Vuforia Engine Support
