LIME FAQs

Here you will find a selection of common questions and topics related to LIME.

 

Q: I’m using a laptop with integrated and dedicated graphics cards. How do I get the best performance out of LIME?

Modern laptops often ship with a dedicated high performance graphics card to run 3D graphics software, and an “integrated” card for general purpose usage (such as for document handling, playing movies etc). The graphics card drivers and operating system handle the switch between the two depending on which software is run. However, the OS does not always get it right, and you may need to override which graphics card is chosen to run LIME. For NVIDIA cards (recommended), the procedure is as follows (Windows 7):

 

 

 

Alternatively, LIME can be run on demand with the NVIDIA processor by right clicking on the software icon and selecting the NVIDIA processor under Run with graphics processor.

 

Q: How do I export a textured model from Agisoft PhotoScan for use in LIME?

Export model as Wavefront OBJ (*.obj). If the model is georeferenced, select the appropriate projected coordinate system. Models exported with a geographic coordinate system (i.e. lat/long) are not compatible with LIME at this time. For versions of LIME prior to 1.1, the Shift (offset) parameter must be set for the X and Y coordinates to reduce large coordinate values. This avoids “jitter” when navigating in 3D caused by graphics card precision.

Q: Can I improve the texture resolution of a model built in Agisoft PhotoScan, prior to export to LIME?

Yes, by increasing the “Texture count” parameter when building the texture. Using the default Texture count (set to one) will result in coarse, pixelated texture for larger models.
