Autodesk Project Neon - the best CAD-related cloud application and a typical example what server clouds can bring to general CAD users - has been updated this Friday. Project Neon takes your 3D scene stored in an uploaded DWG file, puts the cloud servers in hard work and creates photorealistic renderings (raster images) of the views you specify. So the "cloud" simply does the work for you and you don't need the extra hardware performance usually needed for 3D renderings.
The updated version now offers faster renderings (up to 5x!), environment maps, texture filtering, support for larger models, support for sub-entity materials (this was important), more accurate UV mapping, support for proxy objects and 2.5D objects (wide lines).
