You are using URBASEE but your 3D models don't fit in the application or don't work as you would like? Then you've come to the right place! In this article we will explain why and how to optimize your models through a set of best practices.
Why optimise your 3D model?
The URBASEE platform processes your 3D file so that it can be displayed in augmented reality in your application. This processing time can be more or less long depending on the complexity of your model. Always keep in mind that your 3D file must be viewable on a mobile device (smartphone or tablet) and that this type of platform does not have the hardware power of a 3D workstation. You must therefore adapt your model for real-time 3D.
Optimising your 3D model: our experts guide you!
Our experts offer a few tips and tricks to help you get the most out of your augmented reality application.
Make sure you model with as few triangles and polygons as possible. The maximum allowed by the application is 1,000,000 triangles to ensure a smooth use of augmented reality.
- Set up your model in metres. This is necessary for correct visualisation at scale 1. Don't forget to set your model to point 0. This will allow you to use the zoom or to rotate the model on itself.
- Remember to clean up points and vertices outside the 3D model that may be included in the bounding box. This may affect the lighting of the model.
- If you want to model several houses, we advise you to model them one by one in different projects.
- Apply the Reset transform / Reset Object / Reset Xform according to your software in order to take into account your modifications (risk of exploded model, returned,...)
- Remember to remove the cameras and lights so that your bounding box does not become too large, thus lowering the quality of the rendering.
Reminder: DAE, 3DS, FBX, BLEND, IFC, KMZ and WRL files are accepted in URBASEE. To place the associated textures, place the file with its textures in a ZIP archive and load it into your URBASEE workspace. Save your project and synchronise your application.
Thanks to these good 3D modelling practices, you will be able to fully enjoy your augmented reality application. However, if you are still having problems displaying your model correctly, don't hesitate to go to the FAQ [link] or contact us so that one of our experts can answer you.
