Thanks for prompt responses. Now I see how does it work and can test it locally, but the format of JSON file is not clear to me. I exported some objects from blender using three io addon but non of them is loaded. I see that JSON file in example above is a non-idexed file where each vertex is listed three times for each triangle and there is no connectivity section. I would prefer to create JSON file with indexed geometry like the mesh from this website: http://blog.teamtreehouse.com/the-beginners-guide-to-three-js in which section called faces shows vertex connections. Is there any description of acceptable JSON file structure? I use also MeshLab which exports indexed JSON files but these are also not loaded by three.js. Any help will be appreciated.
BTW I see there are two json loaders BufferGeometryLoader and JSONLoader. I tried both but just wondering if there is any difference between them.
PS. One more note about LUT file: range of the color legend is set in main file as lut.setmin and lut.setmax to fixed values. I think it would be more convenient to set these directly from range of the attribute. It will mess up round labesls of the legend ticks but at least there will be a ful range of attribute values on the legend.
Thanks,
