A quick E57 reader implementation for inspecting the data and visualizing the structered scans as well as images. One can see point colors, intensities and invalid points.
I prepared this small code really quickly to test out some E57 functionality and to understand the file type better. There are possible many bugs.
Clone the repository including submodules and build it. I just worked on ubuntu up to know. Not sure what would happen for the other operating systems.
Drag and drop the E57 file. Start inspecting.
Let me know if you want to add something or thinking that you may use it and a bug is creating problem. I will fix it happily :)
