Some useful tips on how to prepare and export models.
The most crucial factor for demonstrating architectural models in augmented reality is the size of the models being rendered at real-time. Most models submitted to us are very information heavy because these models are normally created at 1:1 scale, or modelled without considering Polygon Counts. Due to the size and complexity of detail within these models, they often take too much processing power for most portable devices to render and augment at real-time. Therefore in order to achieve the most robust AR performance, models must be optimised through their polygon count.
The optimum model size for best AR tracking is:
To check the polygon count for 3dmodel please refer to the guidelines below:
Polygon Count in 3dsMax
Polygon Count in Sketchup
Polygon Count in Maya
For models created in Revit, Microstation and Autocad, please export these first as .FBX and check polygon count and file size, and object count in the software's mentioned above.
