Components of Video RAM Usage on Mobile Devices

 

This data refers to the Video RAM memory required to view the model on the supported iOS mobile devices.
Geometry: Based on the triangle count.
Textures: The BIMx application for mobile devices automatically optimizes your textures to a certain degree, but if your BIMx model is too large to be run on your mobile device, you can try to reduce their size and complexity.
If the BIMx model was saved using Global Illumination, additional video RAM memory is required to handle the following two texture components:
Global Illumination of Flat Surfaces: the illumination texture applied to flat surfaces; and
Global Illumination of Curved Surfaces: the illumination texture applied to curved surfaces
You will notice that curved surfaces are less memory-intensive than the flat surfaces.
